Musician Who Lost His Arm Plays Piano Again with AI Prosthesis

A galaxy far, far away is a little closer with the invention of a robotic arm inspired by Luke Skywalker's bionic hand. And while this arm may not wield a lightsaber, it has a greater power for jazz musician Jason Barnes -- it lets him play the piano for the first time in five years. Barnes, who lost much of his right arm in a work accident, is back at the keys with an AI prosthesis created by researchers at the Georgia Institute of Technology. Unlike most prosthetics, it gives the 28-year-old the ability to control each finger individually. With it, Barnes can play Beethoven.
