Simple-to-use Teleoperated 3D Printed Hand: The aim of this project is to create a cheap teleoperated hand that can be easily controlled by its user. In order to reduce cost of prosthetics, we hope to eventually have this system be implemented in prosthesis. Three scenarios were present to 8 subjects from various ages where they tried to determine if a 3D printed hand was grasping or at least touching a stress ball, laying on top of the palm of the 3D printed hand. All subjects were right handed, except for the exception of one ambidextrous subject. The 3D printed hand contained two force sensors to enable tactile feedback on the fingertip of the thumb and index fingers. Only the thumbs and index fingers were operational, but operation of all 5 fingers can be achievable. We determined that we can indeed produce an affordable, working 3D printed hand that gives the user real time tactile information. Even with the lack of a few degrees of freedom in the thumb, the experiment were still successful, giving subjects who were not looking at the 3D printed hand the information needed to determine that they were indeed touching or grasping the stress ball with the movement of their hand. This can also give headway in humanoid robotics or virtual reality environments. More information available in the paper.
