Abstract
A system and method of maintaining a tool position and orientation for a computer-assisted device include a control unit and an articulated structure coupled to the control unit and including a plurality of joints. The articulated structure is configured to support an instrument. The control unit is configured to determine an error that is introduced to a position of the instrument, an orientation of the instrument, or both the position of the instrument and the orientation of the instrument by movement of a first joint of the plurality of joints; and drive at least a second joint of the plurality of joints to reduce the error.
