I read a short story in the 1950s called "Jingle In The Jungle". It featured a boxing trainer named Charlie Jingle who had pieced together an old boxing robot for a big fight in which, of course, the odds were not in his favor. Can't remember the author. But it seems the idea of fighting machines is not at all a new thing.
