This past Saturday a few members of the robotics team ran a booth at the Philadelphia Science carnival. We demonstrated our robot, our 3D printers, and, at the front of the exhibit, our work on prosthetic hands. Xan’s electronic setup was front and center, allowing us to place the EMG sensors on people’s forearms as they walked by to control the hand. About 300 people were able to work the prosthetic, and only few were unable to operate it.
We also heard back from the people running the research part of DuPont Nemours hospital. They have an extremely high end 3D printer, which they allowed us to print two models of our hand on. The quality of these are way beyond what we were capable of doing on our printers. One of them is currently being used by Xan on his research with the myoelectric control system, while the other is being set up for the activation energy and efficiency tests, hopefully completed towards the end of this week.
We’re in the last month of our work here, but we’re really close to finishing a working model.
