Obama Geeks Out Over a Brain-Controlled Robotic Arm That 'Feels'

When Nathan Copeland got into a car accident in 2004, he suffered a spinal cord injury that left him paralyzed in both arms and both legs. Eventually, Copeland got a prosthetic--but one that is very different from most anyone else's out there. Copeland is the first person in the world to use a system created by DARPA and the National Science Foundation, which allows him to "experience" the sensation of touch via a special robotic prosthesis. He has a brain implant that lets him control and feel the system with his mind. Oh, he's also one of the few Americans who has personally met the President of the United States.
