Abstract :
This paper addresses the dynamics and control of direct drive robots with positive joint torque feedback. We analytically derive the system dynamics in closed form. Even though it is coupled and nonlinear in general, it is substantially simpler than the robot link dynamics. We also derive conditions on the robot configuration which result in linear dynamics. Motion control laws for both cases are proposed
