History for robot
In 1923 the play R.U.R., by Karel Čapek, opened in London and New York. In the play “R.U.R.” stands for “Rossum's Universal Robots,” a company formed by an English scientist named Rossum to manufacture humanlike machines called “robots” to do hard, boring jobs. In Czech—the language of what is today the Czech Republic and the original language of the play—the word robota means “forced labor,” and Čapek based his new coinage “robot” on this word. Čapek's play was popular, and soon the word became a general term for machines that can perform the tasks of a person.
