Re: Eliminating Arm Wobble
I work on radio telescopes. They solve this problem by using two motors pushing against each other and on the arm. The control is done simply by issuing a command of torque X to one motor and torque X-K to the other motor, K being the amount of bias needed to keep the motors pushing each other to remove the backlash.
