Abstract
Abstract A transferrable-center compliance system including a remote center compliance (RCC) device being erectable by an axial load in a first range, for establishing a remote center of compliance at, near, or beyond the free end of an operator member; and pliant support means for supporting the RCC device when the RCC device is collapsed by an axial load outside the first range, and for yielding to the RCC device when it is erected with the first remote center of compliance at, near, or beyond the free end of the operator member.
