started my quest looking at more mechanical means like you
suggested... But I got frustrated. The spine bends in a nice arc in
any direction. Maybe I could print vertebrae on a MakerBot and pull
on a string to 'contract the muscle' in the direction of the bend?
But that seems pretty fragile compared to a material that
contracts/bends under voltage, and I swear I've seen this material
used somewhere. I just can't remember where, and can't search for it
because I don't remember what it's called :-(
