A friend just showed this to me. http://www.youtube.com/watch?v=UffOrwSO-HE Apparently it is designed to help people with disabilities like Cerebral Palsy have a more aligned gait. Looks like a tiny robot to me. I really like the natural flow to the movement. Certainly keeping this in mind when it becomes available! It is still being developed at the moment. I know if I were a parent of a kid with CP or other gait effecting disability I'd really like the look of this so that is why I am sharing. It would be cool if using things like this reduced the need for surgeries in people with gait issues.
