The term “robot” is derived from the Slavic word “robota”, which means forced labour. The robot itself is nothing more than a programmable mechanical arm that is controlled from a computer system, the robot controller. A MIG welding robot holds a welding torch and manipulates this around a work piece in a similar way as a human welder.
Definition of a robot according to European standard EN 10218-1 (previously EN 775)
