The Sandia Hand is meant to be a relatively affordable, still-dextrous alternative to the current crop of robotic hands. It costs $10,000, compared to up to $250,000 for a similar high-end hand; is made of plastic; and is mostly produced with parts found in cellphones. The digits attach to the palm through magnets, so they can be easily switched out, or can detach when the hand gets rocked too hard. (Something fun besides the standard fingers, like, say, screwdrivers, could also be attached.) It can even retrieve its digits and reattach them on its own.
