SV7
From Tardis Wiki, the free Doctor Who reference
SV7 was the Super-Voc which supervised the other robots aboard the Sandminer. Taren Capel took control of it and he led the robots in killing the crew. The Doctor tricked it into killing Capel, then deactivated it. SV7 was quite a smart robot and capable of some Human-like thought. SV7 was Silver in colour.
