Gadget
From Tardis Wiki, the free Doctor Who reference
Gadget was a robot used by the crew of Bowie Base One, operated by Roman Groom. Before the Doctor's manipulation, it could travel at approximately two miles per hour. The Doctor later sent it with his TARDIS key out to the TARDIS and had it bring the TARDIS into Bowie Base One.
When receiving or acknowledging commands, it stated "Gadget, Gadget!"
