Abstract: This application relates to an actuation system for assistive wearable devices such as exoskeletons designed to actuate a joint of a wearer of the device. The actuation system comprises a cable that connects a guide member arranged on one side of the joint and active components arranged on the other side of the joint. Applying a tension to the cable causes the cable to apply a force to the joint in a superior direction, which translates into a torque of the joint. The actuation system provides the advantages of having a low profile, and being substantially flexible, compliant, lightweight, and comfortable, while having good controllability and force delivery capabilities.
