Abstract
A system and method of breakaway clutching in a device includes an arm including a first joint and a control unit coupled to the arm. 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 an external stimulus applied to the arm exceeding a first threshold, wherein movement of the first joint is more restricted in the first state of the first joint than in the second state of the first joint, switches the first joint from the second state to the first state in response to a speed associated with the first joint falling below a speed threshold, and prevents the switching of the first joint from the first state to the second state when the arm is in a predetermined mode.
