Interestingly enough when our team practiced on a mostly carpet surface (with some regolith) we didn't have any static problems either. No problems at regional either. However, at Atlanta we had a weird problem where the cRIO would spontaneously reset itself. Someone suggested it may be static, so we put electrical tape across all of the open ports (serial, Ethernet, and exposed module slots). It worked flawlessly after that.

If you truly have a static problem, then I would suggest taping any exposed conductors that are near the wheels, especially if they are advanced electronic components (e.g. Jaguars, Digital Sidecar, Gyro, cRIO).
