Etymology

Origin of robot

< Czech, coined by Karel Čapek in the play R.U.R. (1920) from the base robot-, as in robota compulsory labor, robotník peasant owing such labor


Explanation

A robot is a mechanical creation that can move or act on its own. Science fiction is full of robots. Also called droids, Cylons, and bots, robots are certainly the stuff of science fiction stories. But there are plenty of real robots out there in the world, using their mechanical smarts to make life easier. There are robots that can vacuum the rug, dance, perform surgery, clean oil spills, and even build cars. The field of robotics is growing all the time. Maybe someday you'll even have that robot butler so many of us have dreamed about.
