Re: Solution: Variable position of cylinder in compliance with <R74>

You would need two encoders/pots because the load on the arm varies, based on what kind of tube you're picking up, as well as the location of the end effector in relation to the pivot point. Unless you have some method of reliably measuring the load on the cylinder, your method would not be the most precise option.

We also only have one positioning sensor on the main segment of our arm, but we're switching the motor out for a pneumatic cylinder, since the BaneBots gearbox seized up, causing the motor to melt.

I happen to prefer pneumatics over motors, and I've been trying to influence my team in that direction since ever since I joined.
