Robot

Quick facts

• In technical usage a robot is a programmable, actuated mechanism with a degree of autonomy that can sense and act on its environment — industrial definitions used by ISO and the International Federation of Robotics emphasize a programmed actuated mechanism able to perform locomotion, manipulation or positioning.

• The English word "robot" entered common use after Czech playwright Karel Čapek used it in his 1920 play R.U.R. (Rossum’s Universal Robots); the root is Czech robota, meaning forced labour or drudgery.

• Very early 'robotic' devices were mechanical automata (moving, programmed machines) from antiquity through the Renaissance — e.g., devices described by Heron of Alexandria and later automata makers — showing the idea of self-moving machines long predates modern electronics.

• The first widely recognized industrial robot was Unimate, a programmable manipulator developed by George Devol and deployed on a General Motors assembly line in 1961; that installation established the industrial-robot template used for decades.

• Robots today are a broad class — from fixed industrial manipulators and automated guided vehicles to mobile service robots, surgical robots, autonomous vehicles, and research humanoids — and most deployed robots are industrial or task-specific rather than humanoid companions.
