muscle
I don't know how to spell 'exercise' either... does that make me a geek?
Ed: I 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 :-(
