Re: Balancing an Arm

Our 2011 robot used a gas shock from McMaster on the same side of the arm as the tube manipulator. It was sized in a way to provide a slight assist in lifting the arm, but not so much that it required a lot of motor power to lower it. We did a lot of match to determine the length and pressure and final location.

The other advantage of the gas shock was that it provided some damping and gave stability to the arm as it rotated up or down.
