Does static conduct through plastic or rubber? Because I'm pretty (Again, I fully admit that I know very little about electricity) sure those are both insulators, and almost all robot wheels are made out of those two materials.
That said, the only time we got shocked this year was when we had frame-to-frame contact with another robot, so the material in our wheels might not have even mattered. I'm just trying to understand the phenomenon here.

DUH! I didn't realize those screwheads could be an electrical path into the controller. That solves my "How does the charge get into the electronics" problem.
Is there any chance that the static charge could also be carried through the motor leads into the controller?
