About Aero Hand Open
Seven motors drive tendons routed through the fingers, with underactuated joints allowing the hand to conform around objects instead of commanding every joint independently. The mechanical parts can be printed and assembled with readily available actuators, fasteners and control electronics.
TetherIA publishes CAD files, bills of materials, assembly guidance and software so laboratories can repair, modify or reproduce the hand without depending on a closed supplier. The platform is intended for manipulation, teleoperation and robot-learning experiments where accessibility and iteration matter more than matching the force, sensing or durability of a commercial industrial hand.
