Re: 1551's encoder-controlled arm

A. Encoders with victors. No PID -- it's just not needed on these.

B. We have spares. Several of them. The entire robot is highly modular and easy to replace.

C. The screw should only ever extend out in skewer-like position when we are in scoring position for the middle row -- and thus with nothing in front of us. If the inspectors disagree, we have a plan in place (and a part half-made) to deal with it.
