A machine built to carry out some complex task or group of tasks by physically moving, especially one which can be programmed.
"The factory installed a new robot to automatically assemble the car chassis without any human intervention."
In plain English: A robot is a machine that can do tasks on its own by following programmed instructions.
"The robot cleaned the floor while everyone watched."
Usage: Use the singular form when referring to an individual unit and pluralize as robots rather than robs. This term specifically describes programmable machines that perform physical movements for complex tasks, distinguishing it from simple automated devices or software agents.
The word robot comes from the German term Robot, which was borrowed from a West Slavic language. It entered English with its original meaning of forced labor or serfdom intact.
