For a month, This determined man’s amputated arm was connected to a robotic limb, allowing him to feel sensations and control the prosthetic arm with his thoughts. He says “I closed my eyes, and repeated ‘your hand exists, you can close your fist.’ When I finally succeeded after a month at closing my new hand, I felt that I had accomplished a huge goal.” This inspiring story is just the tip of the iceberg when it comes to research with prosthetic hands. I am currently working in the “Grab Lab” here at Yale University on prosthetics. We use under-actuation to build simple and effective grasping mechanisms. Hopefully we can bring an effective solution to currently disabled people.
