METHOD FOR COMPLIANCE CONTROL Abstract In a method of effecting compliance control over an object subjected to a force, such as in the case of a servo-operated robot manipulator device, parameters are established for compliance and values set for balance of compliance. Positions taken up by the object in response to a detected external force are determined by integrating an equation of motion. Trajectory is calculated in a joint coordinate system with universe kinematics; and from this, velocity and acceleration are obtained. Using this method allows compliance to be specified in any desired Cartesian coordinate system in a form of second-order perturbation including not only stiffness but also damping.
