Abstract
Control systems and methods for a remote joint use position measurements to determine and control the force that an actuator applies to the joint through a linkage. The use of force and feedback allows control of a medical instrument having a linkage that provides non-negligible compliance between the joint and a proximal actuator and particularly allows precise instrument operation even when the position of the distal joint cannot be directly related to the proximal motor position.
