'''''Robot''''' was the first serial of [[Season 12 (Doctor Who 1963)|season 12]] of ''[[Doctor Who]]''. This story had numerous notable firsts and lasts.


==Synopsis==
In terms of firsts, ''Robot'' was [[Tom Baker]]'s debut episode as the [[Fourth Doctor]], which followed on directly from the end of ''[[Planet of the Spiders (TV story)|Planet of the Spiders]]''. It was also the first story to feature new companion [[Harry Sullivan]], played by [[Ian Marter]]. It was the first story for which [[Robert Holmes]] was the script editor.
Mortally weakened by the Spider Queen on Metebelis 3, the Doctor is forced to regenerate. His recuperation is cut short as UNIT investigate a spate of robberies involving components for a top-secret disintegrator gun. The culprit is quickly identified as a highly sophisticated robot built by Professor Kettlewell, which is being ordered to act against its Prime Directive.


Just how is the robot being used to carry out the sinister agenda of the Scientific Reform Society? And can the Doctor rescue Sarah from the robot's clutches and avert a nuclear war?
In terms of lasts, this was the final story produced by Barry Letts. It was the last story in which [[Nicholas Courtney]] had a regular role as [[Alistair Gordon Lethbridge-Stewart|Brigadier Lethbridge-Stewart]], as the character did not appear again until ''[[Terror of the Zygons (TV story)|Terror of the Zygons]]'' the following season. After that, he was entirely absent from the series until ''[[Mawdryn Undead (TV story)|Mawdryn Undead]]'' in 1983. Likewise, [[John Levene]]'s newly promoted Warrant Officer [[John Benton]] made his final appearance as a regular character. His only subsequent appearances were in the aforementioned ''Terror of the Zygons'' and ''[[The Android Invasion (TV story)|The Android Invasion]]''.


==Plot==
Outgoing script editor [[Terrance Dicks]] saw this as an opportunity to quickly secure a contract now that he had returned to the ranks of freelance writing. He convinced his replacement, [[Robert Holmes]], that the programme had a tradition of departing script editors being commissioned by their successors, and so was assigned the task of writing this story.


===Part one===
== Synopsis ==
[[file:Robot_ep1.JPG|thumb|right|The definite article]]
Trouble is brewing once again; a series of robberies are taking place which seem linked to plans for a top secret disintegrator gun. All evidence seems to point to the culprit being a sentient [[robot]], created by an eccentric professor and owned by a think tank. However, the robot's basic programming prevents him from killing, providing a contradiction to the clues.
[[Sarah Jane Smith]] and [[Brigadier Lethbridge-Stewart|the Brigadier]] watch as the [[Third Doctor]]'s features fade into that of the [[Fourth Doctor]]. The newly regenerated Doctor is delirious, waking up to spout random lines from past adventures before falling unconscious again. The Brigadier summons the base medical officer, [[Harry Sullivan|Lieutenant Harry Sullivan]] to take the Doctor to sickbay and care for him.


Meanwhile, something large and mechanical enters a [[Ministry of Defence]] advanced research centre, killing a guard and breaking easily through a gate to steal documents from a vault. In the Doctor's laboratory, the Brigadier confides to Sarah that the plans are for a [[disintegrator gun]]. Sarah asks the Brigadier to arrange for a visitor's pass to the [[National Institute for Advanced Scientific Research]], or "Think Tank", which admits journalists only rarely. The Brigadier is glad to help, and the two leave for his office, just as the Doctor sneaks into the laboratory. Finding the [[the Doctor's TARDIS|TARDIS]] locked, the Doctor discovers the key in one of his boots. Before he can enter his ship, he is interrupted by Harry, who tries to persuade him to return to sickbay.
At the same time, [[Fourth Doctor|the Doctor]] is recovering from [[Third Doctor's regeneration|his latest regeneration]]; can he regain his senses and help [[UNIT]] solve the case before time runs out?


When Sarah and the Brigadier return to the lab, they find Harry shut up in a locker and hear the wheezing sound of the TARDIS starting to take off. Sarah bangs frantically on the police box, causing the Doctor to pop his head out. Sarah tries to coax the still unstable Doctor out of the TARDIS by saying that they need his help to find a stolen secret weapon. She almost fails, until the Doctor recognises the Brigadier and her.

=== Part one ===
[[File:Third-doctor-regenerates.jpg|thumb|left|The Doctor [[regenerate]]s.]]
[[Sarah Jane Smith]] and [[Alistair Gordon Lethbridge-Stewart|the Brigadier]] watch as the [[Third Doctor]]'s features fade into those of the [[Fourth Doctor]]. The newly regenerated Doctor is delirious, waking to spout random lines from past adventures before again falling unconscious. The Brigadier summons the base medical officer, [[Lieutenant]] [[Harry Sullivan]], to take the Doctor to [[UNIT sickbay|sickbay]] and care for him.


The mechanical creature breaks into another facility, this time stealing components from a vault. The Brigadier brings the Doctor to investigate the break-in, but the Doctor seems more interested in a pulverised dandelion on the grounds. He points out that the force needed to do that would have to be about a quarter ton. He also deduces from the stolen items that whoever is doing this is stealing the components of a disintegrator gun. The last component is a focusing generator. The Brigadier orders the factory where it is housed to be guarded.
Meanwhile, something large and mechanical enters a [[Ministry of Defence]] advanced research centre. It kills a guard, scares a guard dog and breaks easily through a gate to steal documents from a vault. In the Doctor's laboratory, the Brigadier confides to Sarah that the plans are for a [[disintegrator gun]]. Sarah asks the Brigadier to arrange for a visitor's pass to the [[National Institute for Advanced Scientific Research]], or "Think Tank", which admits journalists only rarely. The Brigadier is glad to help. The two leave for his office just as the Doctor, dressed in a nightshirt and the previous Doctor's black velvet jacket, sneaks into the laboratory. Finding [[the Doctor's TARDIS|the TARDIS]] locked, the Doctor discovers the key in one of his boots. However, before he can enter his ship, he is interrupted by Harry, who tries to persuade him to return to sickbay.


Sarah goes to visit Think Tank. She is shown around the grounds by the director, [[Hilda Winters]] and her assistant, [[Arnold Jellicoe]]. Think Tank is a pure research facility — once research reaches a certain stage, it is handed off to another organisation with more resources, like the government. The initial work on the disintegrator gun was done by Think Tank. Sarah notices a door marked "No Admittance" and pushes her way through into the former robotics section run by Professor [[J.P. Kettlewell]]. She remembers that Kettlewell left Think Tank after he turned against conventional science, and now works on alternative energy facilities. Sarah nearly slips on a wet patchas she looks around. Jellicoe insists, however, that there is nothing in the section, and he and Winters escort Sarah out.
When Sarah and the Brigadier return to the lab, they find Harry shut up in a locker and hear the wheezing sound of the TARDIS starting to take off. Sarah bangs frantically on the police box doors, causing the takeoff sound to stop and the Doctor to pop his head out. Sarah tries to coax the still unstable Doctor out of the TARDIS, saying they need his help to find a stolen secret weapon. She almost fails, until the Doctor recognises the Brigadier and her.


At [[Emmett's Electronics]], [[UNIT]] sets up barriers, but the Doctor observes that they have covered all directions... except down. Sure enough, the mechanical thing tunnels upward into the vault where the generator is kept. By the time the others arrive, all that is left is a dead guard and a hole in the floor. At the other end of the tunnel in the woods, [[Sergeant Benton]] discovers a giant, rectangular and very deep footprint.
The Doctor has entered the TARDIS to find a new wardrobe. He emerges in a [[Viking]] outfit, complete with horned helmet, much to the Brigadier's annoyance, who points out that UNIT is supposed to be an undercover organisation. The Doctor tries again, but comes out wearing the costume of a playing card jack, which he immediately goes back in to change. His third attempt is a Pierrot [[clown]] outfit, complete with face-paint, which is also met with disapproval. His fourth attempt has him emerge in what will be his regular outfit, with a long multi-coloured [[The Doctor's scarf|scarf]] and floppy hat; the Brigadier decides this look is much better than the ones before.


Sarah goes to see Kettlewell, who brusquely tells her that Think Tank cannot be carrying on his robotics research because no one else has the ability to do so. Still suspicious, she drives back to Think Tank and sneaks back into the robotics section, discovering that the wet patch was actually oil. At that moment, a set of doors opens, and a giant, gleaming robot lumbers towards her menacingly, demanding to know who she is what she is doing here.

===Part two===
Sarah visits Think Tank. She is shown around the grounds by the director, [[Hilda Winters]], and her assistant, [[Arnold Jellicoe]]. Think Tank is a pure research facility — once research reaches a certain stage, it is handed to another organisation with more resources, like the government. The initial work on the disintegrator gun was done by Think Tank.

She remembers that Kettlewell left Think Tank after he turned against conventional science. He now works on alternative energy facilities. Sarah nearly slips on a wet patch as she looks around. Jellicoe insists, however, that there is nothing in the section. Winters and he escort Sarah out.
[[file:Robot_ep2.JPG|150px|thumb|left|[[Sarah Jane Smith|Sarah]] meets the [[Experimental Prototype Robot K1|K1 Robot]]]]
Sarah, panicked, runs to where she came in and meets Winters. The director explains that since Sarah was so insistent on seeing what was in there, they activated the robot as a joke. In response to Sarah's questions, the robot identifies itself as [[Experimental Prototype Robot K1]]. Its purpose is to replace human beings in carrying out hazardous activities like mining or handling radioactive materials. Sarah asks if the robot can be dangerous, and Winters demonstrates by ordering K1 to kill her. K1 is unable to do so, and the conflicting impulses cause it distress. Jellicoe explains that K1's prime directive is to serve and not harm humanity. Sarah observes that that was a cruel demonstration, and apologises to K1 for its distress, despite Winters claiming that the robot has no feelings. After she leaves, Jellicoe tells Winters that the demonstration was dangerous. K1's programming had just been reset.


Jellicoe and Winters adjust K1 again before sending it out. They show K1 a picture of Cabinet Minister [[Joseph Chambers]], telling it that Chambers is an enemy of humanity. Meanwhile, Sarah reports what she has seen to UNIT. The Brigadier cannot act without more evidence. They decide to send Harry to Think Tank, undercover, to gather information. The others go to see Kettlewell, who is hostile at first but warms up when the Doctor shows interest in his work. Kettlewell tells them that he reluctantly ordered K1 dismantled because its capacity to learn and its power began to frighten him. He scoffs at the idea that Winters or Jellicoe would have the ability to alter the robot's programming, but concedes that if they had, it would drive the robot mad.
At [[Emmett's Electronics]], [[UNIT]] sets up barriers against the thief. The Doctor observes they have covered all directions... except down. Sure enough, the mechanical thing tunnels upward into the vault where the generator is kept. By the time the others arrive, all that is left is a dead guard and a hole in the floor. At the other end of the tunnel in the woods, [[Benton]] discovers a giant, rectangular and very deep footprint.


K1 enters Chambers' home, kills him and disintegrates the door of his safe  to steal a set of documents. At UNIT, the Brigadier has discovered that many Think Tank scientists, including Winters and Jellicoe, belong to the [[Scientific Reform Society]], a fringe group advocating a society ruled by a scientific elite. K1 arrives at Kettlewell's lab in a confused state, knowing it has gone against its programming. It asks its creator for help. When the Doctor and the Brigadier go to Think Tank, Winters tells them that K1 has been dismantled, but Winters is aware the Doctor knows she is lying. Meanwhile, Harry arrives at Think Tank disguised as a medical inspector.

Still suspicious, she drives back to Think Tank and sneaks back into the robotics section, discovering the wet patch was actually oil. At that moment, a set of doors opens, and a giant, gleaming robot lumbers menacingly towards her, demanding to know who she is and what she is doing here.


In his lab, the Doctor receives a call from Kettlewell, who tells him of K1's presence. The Doctor agrees to go over, but leaves a note tacked up on the TARDIS in case it is a trap. Indeed, after Kettlewell hangs up, Winters and Jellicoe enter the professor's lab. When the Doctor arrives, he finds the place empty except for K1, who has been ordered to kill the Doctor as an enemy of humanity. Although the Doctor tries to get away, it manages to knock him out. K1 raises its arm to deliver the coup de grace.

[[file:Robot_ep3.JPG|150px|thumb|right|An enthusiastic [[Hilda Winters|Winters]] unveils the robot]]
Before K1 can land the killing blow, Sarah (having read the note) arrives. K1 recognises her as the person who showed concern for its wellbeing, and when Sarah tells it that Think Tank are deceiving it, K1 flails about in confusion and distress. At that moment, Benton and a squad of UNIT soldiers arrive, but it easily shrugs off their gunfire and escapes. They find Kettlewell tied up inside a cupboard and take him back to UNIT headquarters. There, he confirms that Jellicoe and Winters altered the robot's programming and made it unstable. He explains that K1 is made of a living metal he invented, one that can grow like a living organism. That also led him to another discovery, a virus that could biodegrade metal into a recyclable form.


When Sarah discovers that Kettlewell is still a member of the Scientific Reform Society, she persuades him to attend that evening's meeting and let her in secretly. When Benton protests, she points out that neither she nor Kettlewell are under UNIT's jurisdiction and the two leave. When the Doctor wakes up, he has realised that Chambers must have had access to some kind of ultimate threat. The Brigadier explains that some months before, to ensure peace, the governments of [[Russia]], [[China]] and [[United States of America|America]] decided to give the locations and launch codes of their nuclear weapons to a neutral country [[Great Britain|Britain]] for safekeeping, with the intention that Britain could publish these codes if war was imminent and allow things to cool down. Chambers was holding on to these Destructor Codes, and if Think Tank has them, they could hold the world to ransom. When Benton tells them that Sarah has gone off with Kettlewell, the Doctor is alarmed.

When the Doctor and the Brigadier go to Think Tank, Winters tells them K1 has been dismantled, but Winters is aware the Doctor knows she is lying. Meanwhile, Harry arrives at Think Tank disguised as a medical inspector.


At the SRS meeting, Kettlewell opens a side door to let Sarah in. She hides in the meeting room as Winters addresses the membership, ranting that soon they will rule as is their right. To Sarah's shock, she credits this to one man: Kettlewell, who joins them on stage, as does K1. The robot senses Sarah's presence and homes in on her, just as the Doctor arrives to provide a distraction. He knew Kettlewell was the only one capable of altering K1's programming; the attack on him was a ruse to gain UNIT's confidence. Kettlewell explains that for years he had tried to persuade people to stop destroying the environment. Now with Think Tank, he can make them stop instead. The Doctor points out that in science, as in morality, the ends never justify the means, and Kettlewell gets an inkling of Winters' ruthlessness when she orders the Doctor and Sarah killed.

Harry contacts the Brigadier from Think Tank, reporting that the scientists are evacuating to a bunker, but is knocked unconscious and taken captive before he can relate any more. UNIT troops proceed to Think Tank's atomic shelter, but are held off by its automated defences. Winters contacts the Brigadier: they have already given the governments of the world their demands. Unless these are agreed to, in full, in thirty minutes, she will use the Destructor Codes.

Benton and his men knock out the bunker's machine gun nests while the Doctor uses his [[sonic screwdriver]] to detonate the mines surrounding the entrance. Winters sends K1 out, armed with the disintegrator gun, which he proceeds to use on a soldier, and then a UNIT tank. It warns that it will destroy them all.

The Doctor points out that in science, as in morality, the ends never justify the means, and Kettlewell gets an inkling of Winters' ruthlessness when she orders the Doctor and Sarah killed.
[[file:Robot_ep4.JPG|150px|thumb|left|The problem just got bigger]]
In the bunker, Winters has Kettlewell make the international computer linkups so they can use the Destructor Codes. Kettlewell still believes Winters is bluffing, but she disabuses him of the notion, telling him that if the world governments do not give in, she will fire the missiles. The countdown begins.


Kettlewell has a change of heart and tries to stop the countdown, but Jellicoe pulls a gun on him. Harry and Sarah have escaped their bonds and Harry knocks Jellicoe to the ground. Kettlewell holds the countdown while the other two open the doors. As they exit the bunker, K1 swings the disintegrator gun on them. Sarah tries to convince K1 that Think Tank are evil. K1 struggles with the dilemma and fires the gun, disintegrating Kettlewell. With a wail, the robot cries out that it has killed its creator, and collapses. With K1 apparently disabled, the Doctor and the UNIT troops make their way into the bunker.
UNIT arrives at that moment, but using K1 as cover and Sarah as a hostage, Winters, Jellicoe and Kettlewell make their escape. Harry contacts the Brigadier from Think Tank, reporting that the scientists are evacuating to a bunker, but is knocked unconscious by Jellicoe and [[Phillips (Robot)|Phillips]] and taken captive before he can relate any more. UNIT troops proceed to Think Tank's atomic shelter but are held off by its automated defences. Winters contacts the Brigadier; they have already given the governments of the world their demands. Unless these are agreed to, in full, in thirty minutes, she will use the destructor codes.


Winters has resumed the countdown, and although she moves away from the console when ordered, she is confident that no one can stop the countdown in time. However, she has not reckoned on the Doctor, who  reprograms the computer and cancels the order. However, in the mop-up, nobody notices that K1 has revived, and has taken Sarah with it into the bunker. The Doctor realises that K1 is in a state of emotional shock after killing its "father" and has developed an Oedipus complex. K1 intends to carry out Kettlewell's last orders and ensure the destruction of humanity, although the robot assures Sarah that she alone will be saved.

Benton tells the Doctor of Kettlewell's description of the robot's living metal and the accompanying virus he developed. The Doctor is delighted and tells the Brigadier to find the robot while he and Harry go to Kettlewell's lab to cook up a batch of the virus. K1 locks the bunker and restarts to countdown. This time, the world governments' fail-safe procedures are activated in time, and the missiles remain unfired.

As K1 exits the bunker, the Brigadier fires at it with the disintegrator gun. Instead of being destroyed, the robot grows to gigantic size. It picks up Sarah like a doll and heads towards the nearby village. It places Sarah on a rooftop as a pitched battle takes place between K1 and UNIT troops while the Doctor races back with the virus. Driving by K1's feet in his roadster, [[Bessie]], the Doctor throws the batch of virus at it. The virus instantly  spreads over the robot, throwing its growth into reverse. It shrinks down to doll size, and then dissolves completely.

Back at the Doctor's laboratory, Sarah is saddened at K1's demise. She realises that the Doctor had to do what he did, but it had seemed so human. The Doctor observes that it was capable of great good as well as great evil, so one could say that it was human. He suggests a trip in the TARDIS to cheer Sarah up. She agrees, just as Harry enters, asking where they are going. When the Doctor tells him, Harry considers the idea that a police box can go anywhere absurd. The Doctor invites Harry to step inside to, just to prove it is no illusion.
Winters has resumed the countdown. Although she moves away from the console when ordered, she is confident that no one can stop the countdown.

K1 intends to carry out Kettlewell's last orders and ensure the destruction of humanity, although the robot assures Sarah that she alone will be saved.


Harry steps into the TARDIS, and is heard to exclaim in surprise. The Doctor and Sarah follow, grinning.The TARDIS dematerialises just as the Brigadier comes in. Seeing the empty corner of the lab, the Brigadier muses to himself that he will have to tell [[Buckingham Palace]] that the Doctor will be a little late for dinner.

It places her on a rooftop as a pitched battle takes place between K1 and UNIT troops, while the Doctor races back with the virus. Driving by K1's feet in his roadster, [[Bessie]], the Doctor throws the batch of virus at it. The virus instantly spreads over the robot, throwing its growth into reverse. It shrinks to doll size and then dissolves completely.

Back at the Doctor's laboratory, Sarah is saddened by K1's demise. She realises the Doctor had to do what he did, but it had seemed so human. The Doctor observes it was capable of great good as well as great evil, so one could say that it was human. He suggests a trip in the TARDIS to cheer Sarah up. She agrees but wonders why the Doctor wants to do so right now. He has been invited to dinner at [[Buckingham Palace]]. Unlike his predecessor, the Doctor finds much of his work at UNIT to be boring. He simply doesn't wish to do so much work. Harry enters, asking where they are going. When the Doctor tells him, Harry considers the idea that a police box can go anywhere in time and space absurd. The Doctor invites Harry to step inside the TARDIS too, just to prove it is no illusion. Harry does so and is heard by the Doctor and Sarah to exclaim in surprise; they follow him in, grinning. The TARDIS dematerialises just as the Brigadier enters the lab. Seeing the empty corner where the TARDIS was, the Brigadier muses to himself that he will have to tell Buckingham Palace that the Doctor will be a little late for dinner.

==Story notes==
=== Uncredited crew ===
*This was the first ''Doctor Who'' [[serial]] to have location as well as studio material shot on videotape, as opposed to the more usual BBC television drama practice of the time of shooting studio interiors on videotape and location exteriors on film. This was due to the large number of video effects involving the eponymous robot required in exterior scenes, which were easier and more convincing to marry to videotape than to film. The next serial to be produced completely on videotape was ''[[The Sontaran Experiment]]'' later that season. Beginning with ''[[The Trial of a Time Lord]]'' in [[1986]], videotaping exteriors became standard practice for the remainder of the 1963-89 series' run. The revived (2005-) series shoots most scenes on videotape, which is later processed to look like film (though some deleted scenes and other footage included on DVD releases are presented in their original videotape format).
* [[Floor assistant|Floor Assistant]] - [[Geoffrey Posner]] ([[INFO]]: ''Robot'')
*As a consequence of the above point, this was the first colour serial to be recorded entirely on videotape. ([[REF]]: ''[[The Fourth Doctor Handbook]]'')
* [[Senior cameraman|Senior Cameraman]] - [[Colin Reid]] ([[INFO]]: ''Robot'')
*The seeming disappearance of the robot's legs when it grows was due largely to a change in the way in which [[CSO|color separation overlay]] was achieved. Generally, [[Barry Letts]] had ordered blue as the background to all CSO shots during the Pertwee era. However, as with the previous story, ''[[Planet of the Spiders]]'', yellow was used. While this switch had produced generally desirable results for the shots of the [[Whomobile]] in flight in ''Spiders'', it didn't work so well in this story, due to the fact that the reflection of the studio lights on the silver of the robot's body registered as yellow to the camera. When the growing robot was keyed into the shot with Sarah, the CSO process removed all yellow from the shot, which took away not just the yellow background, but also those parts of the robot's body which the camera ''saw'' as yellow.
* [[Grams operator|Grams Operator]] - [[Gordon Phillipson]] ([[INFO]]: ''Robot'')
*Benton is promoted to Warrant Officer. This is not reflected in the closing credits, which continue to give his rank as Sergeant.
* [[Technical manager|Technical Manager]] - [[Derek Thompson]] ([[INFO]]: ''Robot'')
*This story features the debut of another new opening and closing title sequence, again designed by [[Bernard Lodge]] and realised using the '[[slit scan]]' process, but in this instance featuring Tom Baker rather than Jon Pertwee and, for the first time, the TARDIS's police box exterior.
* [[Make-up assistant|Make-Up Assistants]] - [[Ann Edward]], [[Gail Glaser]] ([[INFO]]: ''Robot'')
*Terrance Dicks later said that two major influences for this story were [[Wikipedia:King Kong|''King Kong'']] and Isaac Asimov's [[wikipedia:I, Robot|''I, Robot'']]. Indeed, the scenes in which Sarah Jane is carried by the Robot greatly resemble scenes from ''King Kong''.
* [[Vision Mixer]]s - [[Graham Giles]], [[Fred Law]] ([[INFO]]: ''Robot'')
*This is the first story which makes note of [[the Brigadier]]'s full name: Alistair Gordon Lethbridge-Stewart. Prior to this story, his middle name had never been revealed.
* [[Inlay Operator]] - [[Dave Jervis]] ([[INFO]]: ''Robot'')
*Parts of this story were recorded at the same time as parts of ''Planet of the Spiders''. This not only meant that Jon Pertwee and Tom Baker were literally playing the Doctor at the same time, but also that Elizabeth Sladen and to a lesser extent, Nicholas Courtney and John Levene were having to rush back and forth between the two productions.
* [[Props buyer|Props Buyer]] - [[Bob Warans]] ([[INFO]]: ''Robot'')
*This story marks the final appearance of [[Bessie]] until ''[[The Five Doctors]]'' nine years later.
* [[Producer's secretary|Producer's Secretary]] - [[Sarah Newman]] ([[INFO]]: ''Robot'')
*The TARDIS interior in not seen throughout this serial, nor indeed at any point until ''[[Planet of Evil]]'', the first post-[[Harry Sullivan]] story.
* [[Director's assistant|Director's Assistant]] - [[Joy Sinclair]] ([[INFO]]: ''Robot'')
*[[Director]] [[Christopher Barry]] considered [[Colin Baker]] for the role of [[Arnold Jellicoe]]. ([[REF]]: ''[[The Fourth Doctor Handbook]]'')

== Story notes ==
* This story had the working title ''The Giant Robot''. The existing camera script for part one also lists ''Robot'' as a working title. ([[REF]]: ''[[The Scripts: Tom Baker 1974/5]]'')
* This is the last time that the Third Doctor's [[lab]] is seen.
* This is the last story to feature [[Bessie]] until ''[[The Five Doctors (TV story)|The Five Doctors]]''. It is also the last occasion that the current Doctor drives her until ''[[Battlefield (TV story)|Battlefield]]'' with the [[Seventh Doctor]].

Beginning with ''[[Season 23 (Doctor Who 1963)|The Trial of a Time Lord]]'' in 1986, videotaping exteriors became standard practice for the remainder of the 1963-89 series' run. The revived (2005-) series, by comparison, is largely shot on digital using ARRI ALEXA Camera, ARRI ALEXA XT Camera, Sony Betacam (Unknown) Camera, Sony CineAlta F35 Camera, Sony HDW-F900 Camera and editing was done on the Apple Final Cut Pro 7.
* As a consequence of the above point, this was the first colour serial to be recorded entirely on videotape. ([[REF]]: ''[[Doctor Who The Handbook: The Fourth Doctor|The Fourth Doctor Handbook]]'')
* The seeming disappearance of the robot's legs when it grows was due largely to a change in the way in which [[CSO|colour separation overlay]] was achieved.

* Benton is promoted to Warrant Officer, thus entitling him to be addressed as "Mister". This is not reflected in the closing credits, which continue to give his rank as Sergeant.
* This story features the debut of another new opening and closing title sequence, again designed by [[Bernard Lodge]] and realised using the "[[slit scan]]" process, but in this instance featuring [[Tom Baker]] rather than [[Jon Pertwee]] and, for the first time, the TARDIS's police box exterior. It is the first time in which the title sequence is changed, but the series' logo is not.
* The ''[[Radio Times]]'' programme listing for part one was accompanied by black-and-white head-and-shoulders publicity stills of the Third and Fourth Doctors which depicted a four-stage "regeneration" sequence via trick photography, with the accompanying caption, "Who's Who? The Time Lords never die, they just sort of transmute... and become...? [[Tom Baker]] takes over as Dr. Who this evening in ''Robot'': 5.35". ''(original published text)''
* Terrance Dicks later said that two major influences for this story were ''[[King Kong]]'' and Isaac Asimov's {{wi|I, Robot}}. Indeed, the scenes in which Sarah Jane is carried by the robot greatly resemble scenes from ''King Kong''.

* [[Director (crew)|Director]] [[Christopher Barry]] considered [[Colin Baker]] for the role of [[Arnold Jellicoe]]. ([[REF]]: ''[[The Fourth Doctor Handbook]]'')
* [[Terrance Dicks]]'s novelisation ''[[Doctor Who and the Face of Evil (novelisation)|Doctor Who and the Face of Evil]]'' suggests that the Doctor's first unrecorded visit to the planet of the [[Sevateem]] took place early during this story; he left in the TARDIS one night, performed his initial repair work on the [[Mordee expedition]]'s [[Xoanon|spaceship computer]] and then returned to UNIT H.Q. before anyone noticed he had been gone. This was not derived from any information given in the televised version of ''[[The Face of Evil (TV story)|The Face of Evil]]''.
* This is the first introductory story for a new companion since ''[[The Wheel in Space (TV story)|The Wheel in Space]]'' to not be written by [[Robert Holmes]].
* Professor Kettlewell's hair was a suggestion from [[Edward Burnham]], as his hair actually did go like that naturally if he grew it out long enough.
* The King of Hearts outfit that the Doctor wears originates from a 1972 musical version of ''[[Alice's Adventures in Wonderland]]'', although he's wearing it with the hat worn by the Knave of Hearts (presumably because of his unusually large hat size).
* [[Terrance Dicks]] drew on ''[[The Avengers]]'' episode "The Mauritius Penny", which he co-wrote with [[Malcolm Hulke]], most notably for the scenes in which Sarah Jane infiltrates the meeting of the Scientific Reform Society.
* [[Tom Baker]] thought it would be a great idea for the robot to sing "There's An Old Mill by the Breeze", as [[Michael Kilgarriff]] had a lot of knowledge of music hall songs. He decided against suggesting this to [[Barry Letts]].
* [[Terrance Dicks]] later admitted that he had no idea what the Fourth Doctor would be like at this stage, so he largely based him on [[Tom Baker]] himself.
* [[Eaglemoss Collections]] released a special issue magazine that included a hand painted figurine of Robot K1 on 2 September 2014. It was presented as the fourth special in the ''Doctor Who'' Figurine Collection.
* ''Doctor Who Battles in Time'' released a rare card number 787 of Robot K1 in the Ultimate Monsters which was part of the other card category collections of Exterminator, Annihilator, Invader and Devastator.
* [[Christopher Barry]] defended the infamous model tank shot by saying that [[Barry Letts]] and designer [[George Gallaccio]] didn't take him seriously when he said a model tank wouldn't do.
* [[Nicholas Courtney]] regretted the length of his hair in the serial. He cut his hair prior to his next appearance in ''[[Terror of the Zygons (TV story)|Terror of the Zygons]].''
* This is one of two Doctor debut stories, along with [[An Unearthly Child (TV story)|''An Unearthly Child'']], to not have any extra-terrestrial elements except for the Doctor and the TARDIS. [[Deep Breath (TV story)|''Deep Breath'']] also has robots as antagonists, but they originate from space and not from Earth as with the K1.

*The Robot's legs keep vanishing.
* The robot's legs keep vanishing after growing. ''(This was because the shiny metal of the costume reflected the chromakeyed background, thus causing the robot's legs to disappear. For the DVD release, the ''Doctor Who'' Restoration Team corrected this error by recreating the missing limbs electronically.)''
*The Doctor chops a brick in half, but it's clearly a block of balsa wood. Listen for the noise when it hits the ground.
* The Doctor chops a brick in half, but it sounds like balsa wood when it hits the ground.
*The height of the robot is inconsistent after it grows to a huge size.
* The close-up shot of the Doctor's note shows the opening paragraph says "Professor Kettlewell tells me that he has the robot hidden at his cottage". But when Sarah reads the note aloud, she says "house" rather than "cottage" and also reads it as starting with "Sarah".
*Benton mentions he has been promoted to Warrant Officer, but is still credited as "Sergeant Benton".
* The height of the robot is inconsistent after it grows to a huge size.
*After the giant robot has placed Sarah on the chromakey rooftop, some UNIT soldiers attack it with missiles and grenades. In the quick special effects shot that follows, the smoke from these explosions rises in front of the backdrop of the houses but behind the figure of Sarah (who is supposed to be clinging to the houses), making the composite nature of the image painfully obvious.
* When the robot picks Sarah up off the ground the chromakeyed blanket she is wrapped in can be seen from the creases. When it places her on the rooftop and she grabs the chromakeyed object mapped to the chimney, it clearly wobbles.
*When The Doctor jumps out the UNIT land rover his hat comes off, Tom Baker tries to make a grab for it but doesn't manage to and so he keeps running without it.

In the quick special effects shot that follows, the smoke from these explosions rises in front of the backdrop of the houses but behind the figure of Sarah (who is supposed to be clinging to the rooftop).
 
* Outside Kettlewell's lab, when the soldiers attack the robot, the robot loses it footing and almost falls over.
==Continuity==
* When the robot knocks a UNIT soldier unconscious as it escapes from Kettlewell's lab in part three, the robot's hand visibly doesn't come into contact with the soldier, but the soldier collapses anyway.
*The end of this story leads directly into the opening of the next one, ''[[The Ark in Space]]''. It is the first of a continuous series of adventures for the TARDIS crew, beginning from the end of ''Robot'' and continuing through to ''[[Terror of the Zygons]]'', although [[MA]]: ''[[A Device of Death]]'' takes place in a possible gap between ''[[Genesis of the Daleks]]'' and ''[[Revenge of the Cybermen]]'', and [[PDA]]: ''[[Wolfsbane (novel)|Wolfsbane]]'' is set in another such gap between ''Revenge of the Cybermen'' and Terror of the Zygons.
*The novelisation ''[[Doctor Who and the Face of Evil]]'' suggests that the Doctor's first visit to the planet of the [[Sevateem]] takes place early during this story, when Sarah witnesses the newly regenerated and still delirious Doctor starting to leave in the TARDIS.
*Elements of this story have surfaced in [[BFBS]]: ''[[The Relics of Jegg-Sau]]'', Kettlewell's robot designs are revived in the 26th century, where the Robots once again go mad.
*Hilda Winters (again played by Patricia Maynard) returns in [[BFSJS]]: ''[[Mirror, Signal, Manoeuvre]]''
*In post regenerative confusion, the Doctor refers to ''[[The Time Warrior]]'' ('[[Sontaran]]s perverting the course of human history'), ''[[Invasion of the Dinosaurs]]'' ('I tell you, Brigadier, the [[Brontosaurus]] is large and placid. And stupid!').
*The destructor codes are utilised once more in [[NA]]: ''[[Return of the Living Dad]]''.
*The Doctor uses his [[sonic screwdriver]] to detonate a minefield, much as he did in [[DW]]: ''[[The Sea Devils]]''.
*The Doctor carries a small spyglass in his pocket, much as he later produces in [[DW]]: ''[[The Fires of Pompeii]]''.
*As the Doctor empties his pockets at the SRS meeting, he produces a document from [[Skaro]] and references that [[Alpha Centauri]] table tennis players have six arms, which is consistent with the appearance of their representative in [[DW]]:''[[The Curse of Peladon]]'' and [[DW]]:''[[The Monster of Peladon]]''.
*The Doctor had previously hidden a [[TARDIS key]] inside his shoe in [[DW]]: ''[[Spearhead From Space]]''.


==[[Fourth Doctor - Timeline|Timeline]]==
== Continuity ==
*This story occurs after [[DW]]: ''[[Planet of the Spiders]]''
* The [[Fourth Doctor]] offers [[jelly babies]], as he would frequently do later in this incarnation ([[TV]]: ''[[The Ark in Space (TV story)|The Ark in Space]]'', et. al.) and as the [[Second Doctor]] had done at least twice previously. ([[TV]]: ''[[The Dominators (TV story)|The Dominators]]'', ''[[The Three Doctors (TV story)|The Three Doctors]]'')
*[[TVC]]: ''[[Death Flower]]'' takes place during episode 2 of this story.
* The Doctor states he hates goodbyes. ([[TV]]: ''[[The Name of the Doctor (TV story)|The Name of the Doctor]]'')
*This story occurs before [[DW]]: ''[[The Ark in Space]]''
* In his confusion immediately after his regeneration, the Doctor briefly refers to [[Alexander the Great]]. ([[AUDIO]]: ''[[Farewell, Great Macedon (audio story)|Farewell, Great Macedon]]'')
* In post-regenerative confusion, the Doctor mumbles references to recent events:
** "[[Sontaran]]s perverting the course of human history." ([[TV]]: ''[[The Time Warrior (TV story)|The Time Warrior]]'')
** "I tell you, Brigadier, the [[Brontosaurus]] is large and placid. And stupid!" ([[TV]]: ''[[Invasion of the Dinosaurs (TV story)|Invasion of the Dinosaurs]]'')
* The Doctor again uses [[The Doctor's sonic screwdriver|his sonic screwdriver]] to detonate a [[minefield]]. ([[TV]]: ''[[The Sea Devils (TV story)|The Sea Devils]]'')
* As the Doctor empties his pockets at the SRS meeting, he produces a document from [[Skaro]] ([[TV]]: ''[[The Daleks (TV story)|The Daleks]]'') and references that [[Alpha Centauri (planet)|Alpha Centauri]] table tennis players have six arms, which is consistent with the appearance of [[Alpha Centauri (The Curse of Peladon)|their representative]] to the [[Galactic Federation]], whom the [[Third Doctor]] met on [[Peladon]] on two occasions. ([[TV]]: ''[[The Curse of Peladon (TV story)|The Curse of Peladon]]'', ''[[The Monster of Peladon (TV story)|The Monster of Peladon]]'').
* The Doctor had previously hidden a [[TARDIS key]] inside his shoe shortly after his regeneration into his third incarnation. ([[TV]]: ''[[Spearhead from Space (TV story)|Spearhead from Space]]'')

RealWorld.png

Robot was the first serial of season 12 of Doctor Who. This story had numerous notable firsts and lasts.

In terms of firsts, Robot was Tom Baker's debut episode as the Fourth Doctor, which followed on directly from the end of Planet of the Spiders. It was also the first story to feature new companion Harry Sullivan, played by Ian Marter. It was the first story for which Robert Holmes was the script editor.

In terms of lasts, this was the final story produced by Barry Letts. It was the last story in which Nicholas Courtney had a regular role as Brigadier Lethbridge-Stewart, as the character did not appear again until Terror of the Zygons the following season. After that, he was entirely absent from the series until Mawdryn Undead in 1983. Likewise, John Levene's newly promoted Warrant Officer John Benton made his final appearance as a regular character. His only subsequent appearances were in the aforementioned Terror of the Zygons and The Android Invasion.

Outgoing script editor Terrance Dicks saw this as an opportunity to quickly secure a contract now that he had returned to the ranks of freelance writing. He convinced his replacement, Robert Holmes, that the programme had a tradition of departing script editors being commissioned by their successors, and so was assigned the task of writing this story.

Synopsis[[edit] | [edit source]]

Trouble is brewing once again; a series of robberies are taking place which seem linked to plans for a top secret disintegrator gun. All evidence seems to point to the culprit being a sentient robot, created by an eccentric professor and owned by a think tank. However, the robot's basic programming prevents him from killing, providing a contradiction to the clues.

At the same time, the Doctor is recovering from his latest regeneration; can he regain his senses and help UNIT solve the case before time runs out?

Plot[[edit] | [edit source]]

Part one[[edit] | [edit source]]

The Doctor regenerates.

Sarah Jane Smith and the Brigadier watch as the Third Doctor's features fade into those of the Fourth Doctor. The newly regenerated Doctor is delirious, waking to spout random lines from past adventures before again falling unconscious. The Brigadier summons the base medical officer, Lieutenant Harry Sullivan, to take the Doctor to sickbay and care for him.

Meanwhile, something large and mechanical enters a Ministry of Defence advanced research centre. It kills a guard, scares a guard dog and breaks easily through a gate to steal documents from a vault. In the Doctor's laboratory, the Brigadier confides to Sarah that the plans are for a disintegrator gun. Sarah asks the Brigadier to arrange for a visitor's pass to the National Institute for Advanced Scientific Research, or "Think Tank", which admits journalists only rarely. The Brigadier is glad to help. The two leave for his office just as the Doctor, dressed in a nightshirt and the previous Doctor's black velvet jacket, sneaks into the laboratory. Finding the TARDIS locked, the Doctor discovers the key in one of his boots. However, before he can enter his ship, he is interrupted by Harry, who tries to persuade him to return to sickbay.

When Sarah and the Brigadier return to the lab, they find Harry shut up in a locker and hear the wheezing sound of the TARDIS starting to take off. Sarah bangs frantically on the police box doors, causing the takeoff sound to stop and the Doctor to pop his head out. Sarah tries to coax the still unstable Doctor out of the TARDIS, saying they need his help to find a stolen secret weapon. She almost fails, until the Doctor recognises the Brigadier and her.

The Doctor has entered the TARDIS to find a new wardrobe. He emerges in a Viking outfit, complete with horned helmet, much to the Brigadier's annoyance, who points out that UNIT is supposed to be an undercover organisation. The Doctor tries again, but comes out wearing the costume of a playing card jack, which he immediately goes back in to change. His third attempt is a Pierrot clown outfit, complete with face-paint, which is also met with disapproval. His fourth attempt has him emerge in what will be his regular outfit, with a long multi-coloured scarf and floppy hat; the Brigadier decides this look is much better than the ones before.

The mechanical creature breaks into another facility, this time stealing components from a vault. The Brigadier brings the Doctor to investigate the break-in, but the Doctor seems more interested in a pulverised dandelion on the grounds. He points out that the force needed to do that would have to be about a quarter ton. He also deduces from the stolen items that whoever is doing this is stealing the components of a disintegrator gun. The last component is a focusing generator. The Brigadier orders the factory where it is housed to be guarded.

Sarah visits Think Tank. She is shown around the grounds by the director, Hilda Winters, and her assistant, Arnold Jellicoe. Think Tank is a pure research facility — once research reaches a certain stage, it is handed to another organisation with more resources, like the government. The initial work on the disintegrator gun was done by Think Tank. Sarah notices a door marked "No Admittance" and pushes her way through into the former robotics section run by Professor J.P. Kettlewell. She remembers that Kettlewell left Think Tank after he turned against conventional science. He now works on alternative energy facilities. Sarah nearly slips on a wet patch as she looks around. Jellicoe insists, however, that there is nothing in the section. Winters and he escort Sarah out.

At Emmett's Electronics, UNIT sets up barriers against the thief. The Doctor observes they have covered all directions... except down. Sure enough, the mechanical thing tunnels upward into the vault where the generator is kept. By the time the others arrive, all that is left is a dead guard and a hole in the floor. At the other end of the tunnel in the woods, Benton discovers a giant, rectangular and very deep footprint.

Sarah goes to see Kettlewell, who brusquely tells her that Think Tank cannot be carrying on his robotics research because no one else has the ability to do so. Still suspicious, she drives back to Think Tank and sneaks back into the robotics section, discovering the wet patch was actually oil. At that moment, a set of doors opens, and a giant, gleaming robot lumbers menacingly towards her, demanding to know who she is and what she is doing here.

Part two[[edit] | [edit source]]

Sarah, panicked, runs to where she came in and meets Winters. The director explains that since Sarah was so insistent on seeing what was in there, they activated the robot as a joke. In response to Sarah's questions, the robot identifies itself as Experimental Prototype Robot K1. Its purpose is to replace human beings in carrying out hazardous activities like mining or handling radioactive materials. Sarah asks if the robot can be dangerous. Winters demonstrates by ordering K1 to kill her. K1 is unable to do so and the conflicting impulses cause it distress. Jellicoe explains that K1's prime directive is to serve and not harm humanity. Sarah observes that that was a cruel demonstration and apologises to K1 for its distress, despite Winters claiming that the robot has no feelings. After she leaves, Jellicoe tells Winters that the demonstration was dangerous. K1's programming had just been reset.

Jellicoe and Winters adjust K1 again before sending it out. They show K1 a picture of Cabinet Minister Joseph Chambers, telling it that Chambers is an enemy of humanity. Meanwhile, Sarah reports what she has seen to UNIT. The Brigadier cannot act without more evidence. They decide to send Harry to Think Tank, undercover, to gather information. The others go to see Kettlewell, who is hostile at first but warms up when the Doctor shows interest in his work. Kettlewell tells them that he reluctantly ordered K1 dismantled because its capacity to learn and its power began to frighten him. He scoffs at the idea that Winters or Jellicoe would have the ability to alter the robot's programming but concedes that, if they had, it would drive the robot mad.

K1 enters Chambers' home, kills him and disintegrates the door of his safe to steal a set of documents. At UNIT, the Brigadier has discovered that many Think Tank scientists, including Winters and Jellicoe, belong to the Scientific Reform Society, a fringe group advocating a society ruled by a scientific elite. K1 arrives at Kettlewell's lab in a confused state, knowing it has gone against its programming. It asks its creator for help. When the Doctor and the Brigadier go to Think Tank, Winters tells them K1 has been dismantled, but Winters is aware the Doctor knows she is lying. Meanwhile, Harry arrives at Think Tank disguised as a medical inspector.

In his lab, the Doctor receives a call from Kettlewell, who tells him of K1's presence. The Doctor agrees to go over but leaves a note tacked up on the TARDIS in case it is a trap. Indeed, after Kettlewell hangs up, Winters and Jellicoe enter the professor's lab. When the Doctor arrives, he finds the place empty except for K1, who has been ordered to kill the Doctor as an enemy of humanity. Although the Doctor tries to get away, it knocks him out and raises its arm to deliver the coup de grace.

Part three[[edit] | [edit source]]

An enthusiastic Winters unveils the robot

Before K1 can land the killing blow, Sarah (having read the note) arrives. K1 recognises her as the person who showed concern for its well-being. When Sarah tells it that Think Tank are deceiving it, K1 flails about in confusion and distress. At that moment, Benton and a squad of UNIT soldiers arrive, but it easily shrugs off their gunfire and escapes. They find Kettlewell tied up inside a cupboard and take him back to UNIT headquarters. There, he confirms that Jellicoe and Winters altered the robot's programming and made it unstable. He explains that K1 is made of a living metal he invented, one that can grow like a living organism. That led him to another discovery, a virus that could biodegrade metal into a recyclable form.

When Sarah discovers that Kettlewell is still a member of the Scientific Reform Society, she persuades him to attend that evening's meeting and let her in secretly. When Benton protests, she points out that neither of them are under UNIT's jurisdiction, and they leave. When the Doctor wakes up, he has realised that Chambers must have had access to some kind of ultimate threat. The Brigadier explains that some months before, to ensure peace, the governments of Russia, China and America decided to give the locations and launch codes of their nuclear weapons to a neutral country, Britain, for safekeeping, with the intention that Britain could publish these codes if war was imminent and allow things to cool down. Chambers was holding on to these destructor codes. If Think Tank has them, they could hold the world to ransom. When Benton tells them that Sarah has gone off with Kettlewell, the Doctor is alarmed.

At the SRS meeting, Kettlewell opens a side door to let Sarah in. She hides in the meeting room as Winters addresses the membership, ranting that soon they will rule as is their right. To Sarah's shock, she credits this to one man: Kettlewell, who joins them on stage, as does K1. The robot senses Sarah's presence and homes in on her, just as the Doctor arrives to provide a distraction. He knew Kettlewell was the only one capable of altering K1's programming; the attack on him was a ruse to gain UNIT's confidence. Kettlewell explains that for years he had tried to persuade people to stop destroying the environment. Now with Think Tank, he can make them stop. The Doctor points out that in science, as in morality, the ends never justify the means, and Kettlewell gets an inkling of Winters' ruthlessness when she orders the Doctor and Sarah killed.

UNIT arrives at that moment, but using K1 as cover and Sarah as a hostage, Winters, Jellicoe and Kettlewell make their escape. Harry contacts the Brigadier from Think Tank, reporting that the scientists are evacuating to a bunker, but is knocked unconscious by Jellicoe and Phillips and taken captive before he can relate any more. UNIT troops proceed to Think Tank's atomic shelter but are held off by its automated defences. Winters contacts the Brigadier; they have already given the governments of the world their demands. Unless these are agreed to, in full, in thirty minutes, she will use the destructor codes.

Benton and his men knock out the bunker's machine gun nests while the Doctor uses his sonic screwdriver to detonate the mines surrounding the entrance. Winters sends K1 out, armed with the disintegrator gun, which he proceeds to use on a soldier, then a UNIT tank. It warns that it will destroy them all.

Part four[[edit] | [edit source]]

In the bunker, Winters has Kettlewell make the international computer linkups so they can use the destructor codes. Kettlewell still believes Winters is bluffing, but she disabuses him of the notion. If the world governments do not give in, she will fire the missiles. The countdown begins.

Kettlewell has a change of heart and tries to stop the countdown, but Jellicoe pulls a gun on him. Harry and Sarah have escaped their bonds, and Harry knocks Jellicoe to the ground. Kettlewell holds the countdown while the other two open the doors. As they exit the bunker, K1 swings the disintegrator gun on them. Sarah tries to convince K1 that Think Tank are evil. K1 struggles with the dilemma and fires the gun, disintegrating Kettlewell. With a wail, the robot cries out that it has killed its creator and collapses. With K1 apparently disabled, the Doctor and the UNIT troops make their way into the bunker.

Winters has resumed the countdown. Although she moves away from the console when ordered, she is confident that no one can stop the countdown. She has not reckoned on the Doctor, who reprograms the computer and cancels the order. In the mop-up, nobody notices that K1 has revived and has taken Sarah with it into the bunker. The Doctor realises that K1 is in a state of emotional shock after killing its "father" and has developed an Oedipus complex. K1 intends to carry out Kettlewell's last orders and ensure the destruction of humanity, although the robot assures Sarah that she alone will be saved.

Benton tells the Doctor of Kettlewell's description of the robot's living metal and the accompanying virus he developed. The Doctor is delighted and tells the Brigadier to find the robot while Harry and he go to Kettlewell's lab to cook up a batch of the virus. K1 locks the bunker and restarts the countdown. This time, the world governments' fail-safe procedures are activated in time. The missiles remain unfired.

As K1 exits the bunker, the Brigadier fires at it with the disintegrator gun. Instead of being destroyed, the robot grows to gigantic size. It picks up Sarah like a doll and heads towards the nearby village.

It places her on a rooftop as a pitched battle takes place between K1 and UNIT troops, while the Doctor races back with the virus. Driving by K1's feet in his roadster, Bessie, the Doctor throws the batch of virus at it. The virus instantly spreads over the robot, throwing its growth into reverse. It shrinks to doll size and then dissolves completely.

The end of K1.

Back at the Doctor's laboratory, Sarah is saddened by K1's demise. She realises the Doctor had to do what he did, but it had seemed so human. The Doctor observes it was capable of great good as well as great evil, so one could say that it was human. He suggests a trip in the TARDIS to cheer Sarah up. She agrees but wonders why the Doctor wants to do so right now. He has been invited to dinner at Buckingham Palace. Unlike his predecessor, the Doctor finds much of his work at UNIT to be boring. He simply doesn't wish to do so much work. Harry enters, asking where they are going. When the Doctor tells him, Harry considers the idea that a police box can go anywhere in time and space absurd. The Doctor invites Harry to step inside the TARDIS too, just to prove it is no illusion. Harry does so and is heard by the Doctor and Sarah to exclaim in surprise; they follow him in, grinning. The TARDIS dematerialises just as the Brigadier enters the lab. Seeing the empty corner where the TARDIS was, the Brigadier muses to himself that he will have to tell Buckingham Palace that the Doctor will be a little late for dinner.

Story notes[[edit] | [edit source]]

  • This story had the working title The Giant Robot. The existing camera script for part one also lists Robot as a working title. (REF: The Scripts: Tom Baker 1974/5)
  • This is the last time that the Third Doctor's lab is seen.
  • This is the last story to feature Bessie until The Five Doctors. It is also the last occasion that the current Doctor drives her until Battlefield with the Seventh Doctor.
  • This was the first Doctor Who serial to have location as well as studio material shot on videotape, as opposed to the more usual BBC television drama practice of the time of shooting studio interiors on videotape and location exteriors on film. This was due to the large number of video effects involving the eponymous robot required in exterior scenes, which were easier and more convincing to marry to videotape than to film. The next serial to be produced completely on videotape was The Sontaran Experiment later that season. Beginning with The Trial of a Time Lord in 1986, videotaping exteriors became standard practice for the remainder of the 1963-89 series' run. The revived (2005-) series, by comparison, is largely shot on digital using ARRI ALEXA Camera, ARRI ALEXA XT Camera, Sony Betacam (Unknown) Camera, Sony CineAlta F35 Camera, Sony HDW-F900 Camera and editing was done on the Apple Final Cut Pro 7.
  • As a consequence of the above point, this was the first colour serial to be recorded entirely on videotape. (REF: The Fourth Doctor Handbook)
  • The seeming disappearance of the robot's legs when it grows was due largely to a change in the way in which colour separation overlay was achieved. Generally, Barry Letts had ordered blue as the background to all CSO shots during the Pertwee era. However, as with the previous story, Planet of the Spiders, yellow was used. While this switch had produced generally desirable results for the shots of the Whomobile in flight in Planet of the Spiders, it didn't work so well in this story, due to the fact that the reflection of the studio lights on the silver of the robot's body registered as yellow to the camera. When the growing robot was keyed into the shot with Sarah, the CSO process removed all yellow from the shot, which took away not just the yellow background, but also those parts of the robot's body which the camera saw as yellow.
  • Benton is promoted to Warrant Officer, thus entitling him to be addressed as "Mister". This is not reflected in the closing credits, which continue to give his rank as Sergeant.
  • This story features the debut of another new opening and closing title sequence, again designed by Bernard Lodge and realised using the "slit scan" process, but in this instance featuring Tom Baker rather than Jon Pertwee and, for the first time, the TARDIS's police box exterior. It is the first time in which the title sequence is changed, but the series' logo is not.
  • The Radio Times programme listing for part one was accompanied by black-and-white head-and-shoulders publicity stills of the Third and Fourth Doctors which depicted a four-stage "regeneration" sequence via trick photography, with the accompanying caption, "Who's Who? The Time Lords never die, they just sort of transmute... and become...? Tom Baker takes over as Dr. Who this evening in Robot: 5.35". (original published text)
  • Terrance Dicks later said that two major influences for this story were King Kong and Isaac Asimov's I, Robot. Indeed, the scenes in which Sarah Jane is carried by the robot greatly resemble scenes from King Kong.
  • This is the first story which makes note of the Brigadier's full name: Alistair Gordon Lethbridge-Stewart. Before this story, his middle name had never been revealed.
  • Parts of this story were recorded at the same time as parts of Planet of the Spiders. This not only meant that Jon Pertwee and Tom Baker were literally playing the Doctor at the same time, but also that Elisabeth Sladen and, to a lesser extent, Nicholas Courtney and John Levene, were rushing back and forth between the two productions.
  • The TARDIS interior is not seen throughout this serial, nor indeed at any point until Planet of Evil, the first post-Harry Sullivan story.
  • Director Christopher Barry considered Colin Baker for the role of Arnold Jellicoe. (REF: The Fourth Doctor Handbook)
  • Terrance Dicks's novelisation Doctor Who and the Face of Evil suggests that the Doctor's first unrecorded visit to the planet of the Sevateem took place early during this story; he left in the TARDIS one night, performed his initial repair work on the Mordee expedition's spaceship computer and then returned to UNIT H.Q. before anyone noticed he had been gone. This was not derived from any information given in the televised version of The Face of Evil.
  • This is the first introductory story for a new companion since The Wheel in Space to not be written by Robert Holmes.
  • Professor Kettlewell's hair was a suggestion from Edward Burnham, as his hair actually did go like that naturally if he grew it out long enough.
  • The King of Hearts outfit that the Doctor wears originates from a 1972 musical version of Alice's Adventures in Wonderland, although he's wearing it with the hat worn by the Knave of Hearts (presumably because of his unusually large hat size).
  • Terrance Dicks drew on The Avengers episode "The Mauritius Penny", which he co-wrote with Malcolm Hulke, most notably for the scenes in which Sarah Jane infiltrates the meeting of the Scientific Reform Society.
  • Tom Baker thought it would be a great idea for the robot to sing "There's An Old Mill by the Breeze", as Michael Kilgarriff had a lot of knowledge of music hall songs. He decided against suggesting this to Barry Letts.
  • Terrance Dicks later admitted that he had no idea what the Fourth Doctor would be like at this stage, so he largely based him on Tom Baker himself.
  • Eaglemoss Collections released a special issue magazine that included a hand painted figurine of Robot K1 on 2 September 2014. It was presented as the fourth special in the Doctor Who Figurine Collection.
  • Doctor Who Battles in Time released a rare card number 787 of Robot K1 in the Ultimate Monsters which was part of the other card category collections of Exterminator, Annihilator, Invader and Devastator.
  • Christopher Barry defended the infamous model tank shot by saying that Barry Letts and designer George Gallaccio didn't take him seriously when he said a model tank wouldn't do.
  • Nicholas Courtney regretted the length of his hair in the serial. He cut his hair prior to his next appearance in Terror of the Zygons.
  • This is one of two Doctor debut stories, along with An Unearthly Child, to not have any extra-terrestrial elements except for the Doctor and the TARDIS. Deep Breath also has robots as antagonists, but they originate from space and not from Earth as with the K1.

Production errors[[edit] | [edit source]]

If you'd like to talk about narrative problems with this story — like plot holes and things that seem to contradict other stories — please go to this episode's discontinuity discussion.
  • The robot's legs keep vanishing after growing. (This was because the shiny metal of the costume reflected the chromakeyed background, thus causing the robot's legs to disappear. For the DVD release, the Doctor Who Restoration Team corrected this error by recreating the missing limbs electronically.)
  • The Doctor chops a brick in half, but it sounds like balsa wood when it hits the ground.
  • The close-up shot of the Doctor's note shows the opening paragraph says "Professor Kettlewell tells me that he has the robot hidden at his cottage". But when Sarah reads the note aloud, she says "house" rather than "cottage" and also reads it as starting with "Sarah".
  • The height of the robot is inconsistent after it grows to a huge size.
  • When the robot picks Sarah up off the ground the chromakeyed blanket she is wrapped in can be seen from the creases. When it places her on the rooftop and she grabs the chromakeyed object mapped to the chimney, it clearly wobbles.
  • After the giant robot has placed Sarah on the chromakey rooftop, some UNIT soldiers attack it with missiles and grenades. In the quick special effects shot that follows, the smoke from these explosions rises in front of the backdrop of the houses but behind the figure of Sarah (who is supposed to be clinging to the rooftop).
  • Outside Kettlewell's lab, when the soldiers attack the robot, the robot loses it footing and almost falls over.
  • When the robot knocks a UNIT soldier unconscious as it escapes from Kettlewell's lab in part three, the robot's hand visibly doesn't come into contact with the soldier, but the soldier collapses anyway.

Post-regeneration stories
For the purposes of this list, a "post-regeneration story" is one in which the after-effects of a regeneration is actually and initially depicted and the Time Lord fully settles into their new body. For this reason, Rose is not included below, even though it is commonly thought of as a "post-regeneration story". It doesn't actually include a clear scene of regeneration, and the preponderance of stories in other media confirm that the Ninth Doctor has not immediately regenerated prior to the story.

Regeneration is usually considered a biologic process exclusive to Time Lords and a few other species. However, some consider Regeneration to also be a "post-regeneration story", though neither describes anything close to a biological process.
