Robotic Arm

This handout frame grab from video, provided by UPMC, taken Monday, Sept. 19, 2011, shows Katie Schaffer getting a high-five from a mechanical prosthetic arm in a testing session at a University of Pittsburgh Medical Center research facility in Pittsburgh. Tim Hemmes had a chip implanted on the surface of his brain that reads his intention to move his paralyzed arm and sends that instruction instead to an advanced bionic arm.
