Robot [SEP] Origin of the term 'robot'
'Robot' was first applied as a term for artificial automata in the 1920 play "R.U.R." by the Czech writer, Karel Čapek. However, Josef Čapek was named by his brother Karel as the true inventor of the term robot. The word 'robot' itself was not new, having been in the Slavic language as "robota" (forced laborer), a term which classified those peasants obligated to compulsory service under the feudal system (see: Robot Patent). Čapek's fictional story postulated the technological creation of artificial human bodies without souls, and the old theme of the feudal "robota" class eloquently fit the imagination of a new class of manufactured, artificial workers.
