Robert Gaunt tests Nathan Copeland's ability to detect touch by tapping fingers on a robotic hand. Robert Gaunt tests Nathan Copeland's ability to detect touch by tapping fingers on a robotic hand. Twelve years ago, a car wreck took away Nathan Copeland's ability to control his hands or sense what his fingers were touching. A few months ago, researchers at the University of Pittsburgh and the University of Pittsburgh Medical Center gave Copeland a new way to reach out and feel the world around him. It's a mind-controlled robotic arm that has pressure sensors in each fingertip that send signals directly to Copeland's brain.
