This is absolutly amazing. I cannot believe how far Humankind has come to actually making something such as a robotic arm come to life. Dean Kamen is one of the most amazing men in the world, and is way up there with the likes of Galileo, Newton, and other inventors. His "Luke" arm as it is dubbed possible the greatest invention in medicine this century. Not only has he achieved what some have called the impossible my recreating a limb, but he has given back to these people the dignity that they so deserve.
"Kamen's arm, dubbed "Luke" (after Skywalker, I assume), is an incredibly sophisticated bit of engineering that's lightyears ahead of the clamping "claws" that many amputees are forced to use today. The arm is fully articulated, giving the user the same degrees of movement as a natural arm, and is sensitive enough to pick up a piece of paper, a wineglass or even a grape without mishap."
