The QB SoftHand 2 is a research-grade underactuated anthropomorphic dexterous hand from qbrobotics, featuring 19 anthropomorphic DoFs driven through 2 synergies by just 2 motors for human-like synergistic grasping. It weighs 0.94 kg, measures 220 × 135 × 90 mm, and supports a nominal 2 kg pinch / 3 kg grasp payload. Dislocatable self-healing finger joints combined with underactuated synergistic grasping enable adaptive enveloping of objects of varied shapes. Control runs over RS485 (4 Mbps) or CAN FD (5 Mbps) with 24 V DC power, supporting the custom QB protocol and ROS; an industrial version is also available.
