Abstract
A force feedback velocity control measures the forces adjacent the end point of an arm being controlled and adjusts the stiffness of a manual controller in any one direction by scaling the end point force in the corresponding direction and adjusting the scaled force based on the degree of displacement of the manual controller away from a datum or zero velocity position in the one direction. A suitable deadband zone is provided surrounding the datum position.
