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 and including 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 and 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. 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. In some embodiments, the external stimulus applied to the arm is a stimulus detected on the first joint or a stimulus detected on a second joint of the arm.
