Six motors drive 13 joints, so the hand can both pinch small items precisely and grasp larger ones firmly. In addition, springs built into the joints let the fingers flex on contact and help prevent damage in collisions. Users can also unscrew the fingertips and swap in sensors or different materials. Moreover, the hand mounts directly on popular collaborative robot arms. Therefore, students and researchers can start experimenting quickly with free control software or simple Python scripts.
