The DARPA-funded DEKA Arm System is an amazingly life-like prosthetic arm controlled directly by electric signals from the muscles. It’s the first such prosthetic available to the general public. And it can help you climb a rock wall like a badass.
By plugging into the body’s electric signals, the DEKA arm allows for close to natural movement. That can mean delicate manoeuvres like picking up eggs. It can also mean, as illustrated in this new DARPA video, feats of strength like this Army volunteer amputee scaling a rock wall.
