I don't really see the point of this. Why don't you just define your stop position as "10" and then program it to stop at 10?

...because this arm goes to eleven. It goes one farther.

You know, some times youre at ten, and you just need that push off the clif, so you turn up to eleven...

Question: Why do teams put user input things on the robot? We've always put any toggles on the driver station and never had a problem.

I'm guessing here that this team put a potentiometer on the pivot of this arm. The movement of the arm turns the shaft of the pot and they are taking a voltage drop across the resistor to translate into angle...the knob and the "11" are only decorative (but great).

In the period of FRC history between ~2005 and ~2009, it was popular to use a user-input device was mounted on the robot to select between different autonomous modes.

Many teams still do this. It makes it easy to switch "on the fly" when setting up for a match

That is 100% correct. The POT gives us the position of the arm allowing us to then do presets on the arm, have more precise control in autonomous and plus... it can go to eleven just in case we need to move the arm just that little bit further ;).

This year for FTC actually, my team decided to use a 6 position rotary switch to switch between different autonomous's, as well as a pot for a time delay. Between matches, we found ourselves often changing our code to account for our alliance partners, but now we think we have a more solid strategy plan going into state.
