Long before Karel Čapek introduced the word “robot” to the general vocabulary in his 1920 play R.U.R., people had a pretty good idea of what an “automaton” or a “mechanical man” did. They learned it from popular media. Short stories, newspaper articles, vaudeville acts, comic strips, and more toyed with the idea of humanoid mechanical servants.

Not until after World War II did a robot automatically conjure an image of a mechanical human, and that was largely because a word was needed to separate robots from the computer brains that increasingly took the robot’s place in media.
Before WWII, in fact, robot was frequently applied to any automatic machine which functioned with constant human supervision. Before R.U.R. mechanical man or automaton did much the same.
