Abstract
A servo system includes a servo loop incorporating an articulated mechanical arm or other controllable element, resolved motion rate control apparatus or other coordinate transformation apparatus, and an accommodation branch. The transfer characteristics may be readily adjusted to constrain the controllable element to accomplish a desired task, and the accommodation branch transfer characteristics may be readily modified to accomplish the performance of many different tasks without modifications to other portions of the system.
