Nissan's new concept design for a personal mobility device sure is, well, interesting. It looks like a pair of roller skates connected to ski poles, and it supposedly lifts your feet and walks for you, like automated stilts. Sure it does. Is this supposed to be helpful for people who have trouble walking? This seems like it'd be tough to get on if you're perfectly healthy, let alone someone with disabilities.
