The word robot came into English from a polish play R.U.R. (Rossum's Universal Robots). The robots in the play were organic rather than mechanical.

From the wiki entry it replaced older words android or automaton. Automaton or, automata have a long history going back to the ancient Egyptian and Greeks. From Mythical - like Daedalus or Hephaestus, to historical like Hero. But, just to tie it back in to somethign that was mentioned above, the only surviving example is the Antikythera mechanism.
