An exoskeleton system includes a cable, an exoskeleton device, a controller, and a motor. The exoskeleton device includes a frame comprising a first portion coupled to a second portion by a joint, a first crossbar supported by the first portion of the frame, and a second crossbar supported by the second portion of the frame. The first crossbar is configured to redirect the cable toward the second crossbar, and the cable is configured to affix to the second crossbar. The motor is connected to the cable and configured to cause the cable to provide a torque about the joint. The controller controls the motor to adjust the torque. The cable provides the torque by exerting a first force on the first crossbar and a second force on the second crossbar. The cable provides the torque about the joint in a first direction.
