Abstract
A system and method of breakaway clutching in a device includes a plurality of links coupled by a plurality of joints, a brake coupled to brake a first joint of the plurality of joints, and a control unit operatively coupled to the brake. The control unit includes one or more processors. The control unit switches the first joint from a first state of the first joint to a second state of the first joint in response to a determination that an external stimulus applied to the plurality of links or the plurality of joints meets at least a first criterion and switches the first joint from the second state to the first state in response to a speed associated with the first joint meeting at least a second criterion. The control unit causes more braking with the first brake in the first state than in the second state.
