Like I said in my post above, our team found out the hard way that pots have inherent inaccuracies that make it inadvisable to use them as the safety cutoff. They can be used to determine position when a couple of degrees don't matter, but when something like the motors of your arm/whatever the arm is capable of running into is at stake, don't trust a potentiometer to be 100% accurate.
