I'm quite amazed that using springs in robots is sort of a new thing.
I was thinking about making amateur robot with two wiper motors, in-parallel, through strings, per joint. Wiper motors seem to me to be pretty fast and strong (and cheap), and use worm gear so they could hold the springs tensed without using energy proportional to tension.
