Over at Engadget they have a post about Berkeley Bionics and an exoskeleton that they are working on to assist paraplegics walk. This is particularly interesting to me because I have lost about 75% of my ability to walk because of a degenerative disorder. It's great to see that so much progress has been made and by the time I can no longer walk this device may be available and the bugs worked out. Hooray!
There is some pretty cool video on the link.
