The controller unit runs the device. It captures the wearer’s movement and intent, senses the limb’s position and surroundings, decides how much to assist, drives the powered joints, and links to clinician systems. It also sets adaptive assistance by adjusting resistance, speed, and range of motion to the user in real time.
