Dean Kamen has done it again.

One of the world’s most interestig inventors, entepreneurs, and engineers, Kamen has brought to prototype a fully operational robotic arm which promises to revolutionize prosthetics as we know it.

Dean says that fatalities are down because of battlefield tech and triage methods. But that many soldiers are coming back missing limbs. He wanted to make an arm to replace their missing ones. He wants it sensitive enough to pick up a grape or allow soldiers to use a razor to shave, but be self-contained in terms of power. And a two- year deadline.

He say that a year later, they built an 8.9-pound arm using titanium, custom motors, and so on. There’s 18 degrees of freedom, and they’re now seeing a demo of a man who is scratching his nose. Dean says he did this in one year.

The control techniques are revolutionary. He’s playing a video of a guy who didn’t have both his arms for 18 years, and learned how to use the arms effectively in less than two dozen hours of training. He’s showing a video that shows a guy who knows how to punch, pass a Ping Pong ball to his friend and pour a drink for another man who is holding a cup with the same type of arm. Then the video shows Chuck, the man with no arms, for the first time in 13 years, feeding himself cereal. source

Thank you, Mr. Kamen!
