Robotic prostheses have reached a whole new level. We've seen different sorts of them over the years, many of them typically revolving around the hand rather than an entire arm. Les Baugh is different. He lost both arms at the shoulders a handful of decades ago in an accident, and thanks to the hard working scientists at John Hopkins University, he has received a robotic replacement. Baugh has been fitted with two robotic arms he is slowly learning to control.
