Gadget

Gadget was a robot used by the crew of the human Mars colony Bowie Base One in 2059. It was operated by base technician Roman Groom, who created it.

Profile
Groom created Gadget using parts from the powerfully strong drones used to construct the colony originally. When receiving or acknowledging commands, it said, "Gadget! Gadget!", which its creator said amused him. Gadget had no sentience and little autonomy. It depended on an operator controlling it by means of a pair of gloves. It had similar level of dexterity to a human. At least one person could ride it much as they could a Segway.

Prior to the the Doctor's using the sonic screwdriver to give it the power to travel at prodigious speeds, Gadget could travel at approximately two miles per hour. After this adjustment the Doctor and Adelaide Brooke were able to ride Gadget in order to escape from Flood-infected Andy Stone and Tarak Ital. The Doctor, as suggested, doesn't like funny robots, but saved Gadget from the Flood. Adelade critisised this, saying "I thought you didn't like funny robots!". The Doctor later sent it with his TARDIS key out to the TARDIS and had it bring the TARDIS into Bowie Base One. After arriving on Earth. Gadget lost contact with its control signal, and shut down.
