In 1921, a play about robots premiered at the National Theater in Prague, which was the capital of Czechoslovakia at the time. Karel Capek’s “R.U.R.” (Rossum’s Universal Robots) marks the first time the term “robot” referred to an artificial being. Capek coined the term for his artificial persons, using the Czech word for “forced labor” as the basis for the word. Capek’s term “robot” entered the English language in 1923. Source: Wired.com
A robot is a machine—especially one programmable by a computer— capable of carrying out a complex series of actions automatically. Robots can be guided by an external control device or the control may be embedded within.
