Summary:A computer-assisted system includes a repositionable structure configured to support an instrument and a control unit. The control unit is configured to: while a remote center of motion (RCM) is set at a first position, receive a command to move the repositionable structure with a commanded motion; determine whether driving the plurality of joints to move the repositionable structure in accordance with the commanded motion while maintaining the remote center of motion RCM at the first position would violate a limit of the repositionable structure; and, in response: determine an alternative motion of the plurality of joints based on the commanded motion and the first position, wherein driving the plurality of joints in accordance with the alternative motion would not violate the limit, and would move the RCM to a second position different from the first position, and drive the plurality of joints in accordance with the alternative motion.
