A robot is provided with a dynamically controlled center of mass which is decoupled from the end effector. The robot is comprised of a moving arm including a redundant linkage of connecting links and joints coupled to an end effector. The movement of the links and joints of the robot are coordinated by a dynamic servo controller. The robot has at least twice as many degrees of freedom as the number of operating dimensions. Also, for each dimension of operation, there is one group of masses that moves in the same direction as the end effector and another group of masses capable of independently moving in the same or opposite direction. This separation of the motion of the center of mass from the motion of the end effector can be used to decrease reaction forces and to generate significant forces at the end effector.
