Brain implants control robot arm well enough to grab a beer
A paralyzed man named Erik Sorto has finally been able to drink beer on his own after 13 years, and it's all thanks to a robotic arm controlled solely by his mind. If you've been following our robotics coverage, you'll know it isn't the first mind-controlled robo limb -- a DARPA-funded project once allowed a woman to feed herself chocolate, while the one developed by the Braingate2 consortium helped another woman drink coffee on her own. This particular technology, however, works quite differently from the others. Its creators, a team of researchers from various institutes led by Caltech, implanted the neural chips needed to control the arm into a part of the brain called "posterior parietal cortex" or PPC.
