38 DoF... YQ Bionics has shared a first look inside the Y-Hand M2, which it calls the world's highest-DoF bionic hand. Look at the joints. Bone-like segments, cartilage-like components and braided ligaments work together around curved joint surfaces. The hard parts carry compression while the soft elements carry tension, giving the fingers compliance built into their structure. The pull comes from its in-house YQ Motors and YQ Muscles artificial muscle modules. Tendons running through sheaths carry that force across multiple joints, letting several actuators work together to move the fingers. Encoders and force sensors tell the controller how the hand is moving and what forces it's experiencing. Combined with vision, that feedback helps the fingers conform to an object's shape and maintain their grip.
