Prosthetic Hand

I was part of a team of students who were working on designing a prosthetic hand for a real person who lost their fingers in an equestrian accident. Because she previously had her fingers, and still had all the muscles we decided to go with a design which would detect muscle contraction and use servos to move the robotic fingers in response. The picture above is of one teammate's arm with the sensor on it. This was the first sensor we went with, but since it's readings were not accurate we switched to a different sensor (not pictured). To create the hand we also 3d scanned the hand missing the fingers along with the person's other hand which we would use for reference. We converted this into a 3D model. Using this model we could design the hand to fit on the person's hand along with designing the fingers that would move. Even with how far this project got, we were unfortunately unable to complete it.
