Living proof that a robotic limb can be responsive and agile. This is work from US Defense Advanced Research Projects Agency in helping soldiers restore limbs and, most importantly, confidence and hope.
“Prosthetic limbs that can be controlled by thoughts are showing great promise, but without feedback from signals travelling back to the brain it can be difficult to achieve the level of control needed to perform precise movements. By wiring a sense of touch from a mechanical hand directly into the brain, this work shows the potential for seamless bio-technological restoration of near-natural function.” – Justin Sanchez
