Abstract:
A system and method of breakaway clutching in a device includes an arm having 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. Movement of the first joint is more restricted in the first state than in the second state. The control unit further 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. The first threshold is based on at least one first property of the arm. The speed threshold is based on at least one second property of the arm.
