Hugo's father explains how the robot works
Scene from Hugo with the automaton, a early mechanical robot.
Hugo: What does he do?
Hugo's father: He's a wind-up figure. Like a music box. This is the most complicated one I've ever seen by far. See this one. This one can write. Magicians used machines like this when I was a boy. Some walked, some danced, some sang. But the secret was always in the clockwork.
Can we fix him?
Of course we can fix him.
