The next generation in prosthetic arms will soon be helping amputees get a grip in the real world. The LUKE arm, which was previously known as the Deka Arm, was developed under DARPA’s Revolutionizing Prosthetics program by DEKA Research & Development Corp. It received marketing approval from the U.S. Food and Drug Administration (FDA) in 2014 and is now set to hit the market later this year.
