Force Servo is a servo drive with a feedback from a force sensor. The value of force is proportionate to the control signal and does not depend on the position of the arm. Force servo creates minimal friction between base and load. It's arm automatically runs away from any load which was applied from outside. For example, you can rotate the arm with a burn out match. This allows to isolate the load from vibrations on the unstable base. You may think, that it is not possible to lock the position with such servodrive, but actually we are getting more accurate control. Our devices have no information about the position of the unstable base. The position is controlled with respect to the target in a 3D space. Other devices are using fast processors to detect and correct the position error regarding unstable base.  We are preventing the transfer of the unwanted swinging.
