A null seeking control system for a remote center compliance (RCC) device including: detector means for sensing the position of the operator means of an RCC device relative to the fixed portion of that RCC device; a threshold circuit, responsive to the detector means, for determining for each degree of freedom whether the operator means is at a null region, offset in a first direction or offset in a second direction relative to the fixed portion of the RCC device; and a correction circuit, responsive to the threshold circuit, for providing an error correction signal to maintain the null position of the operator means relative to the fixed portion of the RCC device. |
