CHOHO Hand

CHOHO Hand is a five-finger chain-driven hand developed by CHOHO. Official first-generation materials specify 17 total degrees of freedom—7 active and 10 passive—and a hand mass of 715 g. Miniature sprockets and chains transmit power, coordinating the thumb with the other fingers to form grasps. Company materials describe irregular-part grasping, precision assembly and wire-harness arrangement, and document a robot-mounted water-serving demonstration, illustrating integration of a chain-driven end effector with robotic manipulation.
