Did you know?

In 1920, Czech writer Karel Čapek published a play titled R.U.R. Those initials stood for "Rossum's Universal Robots," which was the name of a fictional company that manufactured human-like machines designed to perform hard, dull, dangerous work for people. The machines in the play eventually grew to resent their jobs and rebelled—with disastrous results for humans. During the writing of his play, Čapek consulted with his brother, the painter and writer Josef Čapek, who suggested the name robot for these machines, from the Czech word robota, which means "forced labor." Robot made its way into our language in 1922 when R.U.R. was translated into English.

Etymology

Noun

from Czech robot "a machine that looks human and performs dull or dangerous work," from robota "forced labor, work"

Word Origin
In 1923 a play by the Czech author Karel Čapek introduced the word robot to English. The title of the play, R.U.R., stood for "Rossum's Universal Robots," a fictional company that manufactured robots. These humanlike machines were supposed to perform all the hard, dull, and dangerous work for people, but they finally became resentful and rebelled, killing all humans. Čapek formed the word robot from the Czech robota, meaning "forced labor." The play was very popular and influential. As a result, the word robot came to have several meanings, including "a human being who has become brutal and insensitive or machinelike because of overwork and mistreatment." It is used today for machines that may not look human but do perform dangerous or dull work.
