What a great job the team at Johns Hopkins University Applied Physics Laboratory did. They built this Double Prosthetic Arm with Mind Control to allow Les Baugh to once again have arms and hands. He lost them in an electrical accident over 0 years ago. I can’t imagine the feeling Les has after so many years living without arms and now finally have some high tech versions to work with. They are controlled using nerve signals so Les will learn to control them with his mind. Surely this will be a challenging task but the reward is outstanding!

”We use pattern recognition algorithms to identify individual muscles that are contracting, how well they communicate with each other, and their amplitude and frequency,†Chi explained. “We take that information and translate that into actual movements within a prosthetic.â€
Then Baugh was fitted for a custom socket for his torso and shoulders that supports the prosthetic limbs and also makes the neurological connections with the reinnervated nerves. While the socket got its finishing touches, the team had him work with the limb system through a Virtual Integration Environment (VIE), a virtual-reality version of the MPL.”
