Thread-powered movement supportKinethreads wraps around the chest, arms, and legs like a second skin. Nylon threads run through fabric channels, connected to compact motors that act as synthetic tendons. A sleeve covered the bicep and forearm, with threads running from shoulder to wrist. Four motors controlled each arm: one for shoulder flexion, one for the elbow, and two for rotation and extension. Motors shifted to a belt pack for mobility, with a lithium-polymer battery supplying two hours of active use.
