Dean Kamen is known to many as the inventor of the failed Segway transportation vehicle.  But now he’s clearly moved on to bigger and better things.  In conjunction with the Defense Department and DARPA, Kamen’s been developing an advanced prosthetic arm internally called “Luke” (named after Luke Skywalker).  Luke is being made specifically for injured U.S. troops who tragically lose their arms in battle.  It is by for the most impressive prosthetic I’ve ever seen in practical use.  See for yourself in the video above.
