...That team felt that it was an item worthy of FIRST's consideration for next year, because the effect ought to be minimal. Note, however, that I believe that their proposed solution involved a non-polarized capacitor across the leads, instead of to the frame or case of the motor.

Tristan,

The team was not 177. It was 173 (Rage) but I am familiar with their problem. You are correct that a non-polarized cap, installed across the motor terminals, eliminated the problem but was not legal this year.

BTW, Rage's technical mentors are (IMHO) top notch and there was no wiring error that I could find.

Mike

Yes, it was us. We consulted with the inspectors before adding the capacitors, and were told it was not legal.
We went through the competition without it, and the camera still worked.
I hope FIRST looks into this issue.
