A robot is a mechanical device with the ability to do work without the help of a living organism. The most common type of robot is an android (a humanoid robot, e.g. Kamelion, who could also shape-shift), but they come in various forms such as dog-like (e.g. K-9). (DW: The King's Demons, The Invisible Enemy) On many planets Robots were used as a servile labor force sometimes generating strong emotions in people. (DW: The Robots of Death) They were powered in many different ways such as by Black light. (DW: Four to Doomsday)

Robots are not to be confused with machines, which can be called thinking machines. The difference is that while machines can function by independently, robots require a control.
