Goats inspired this prosthetic leg for rock climbers

For all the neural-controlled, bluetooth-enabled and sport-specific prosthetics humanity has designed over the years, one thing remains constant: most of of them are lousy for climbing rock faces. Design student Kai Lin learned this while researching artificial limbs in a prosthetic-design class at Pratt Institute — traditional leg prosthetics don’t have enough grip or articulation to facilitate effective climbing. Lin’s solution to the problem is almost elegant in its simplicity. He designed a prosthetic leg inspired by one of nature’s best rock climbers: the mountain goat.
