Dean Kamen's Ibot Wheel Chair Helps Handicapped.

In my days wheel chairs were just that, a chair with wheels. Thanks to Dean Kamen the inventor of the Segway ,the heart stents , and many other creations, wheel chairs can do many things. The Ibot climbs stairs, goes down stairs, travels at high speeds, stands up so your at eye level to a standing people, and can travel in mud and sandy beaches. To look at the picture it looks unstable, but on You Tube videos people can push agaist it with full force and not tip it over. Check this link to watch it in motion:
