Abstract
A robotic system includes an articulated member comprising a joint and configured to be manually moved by a user to facilitate performance of a task and a controller. The controller is programmed to determine whether an angular position of the joint is moved within an angular range of motion defined by a braking region, generate a force feedback signal compensating for a gravitational load on the articulated member to inhibit manual movement in space of at least a portion of the articulated member when the angular position of the joint is in the braking region, and maintain the force feedback signal until a user disengages the force feedback.
