I hope it helps. I will be cheering for you and your team at Championship. It would be great to see you all back in Texas again.

You are correct. The isolation of the electronics from the frame is checked with a hand-held meter set to measure Ohms. The highest voltage that such a test would apply between the electronics and the chassis would be 9V or less since these meters are typically powered with 9V batteries or some number of AA's (I have never seen more than 6). The insulation or air gap needed to prevent 9V from arcing across is pretty small (a fraction of a mm). Electronic components rated to resist static-discharges typically have ratings of at least 1500V, often 2500V. Any half decent static charge would have no trouble arcing over the small air gap (or punching through the thin insulation) needed to satisfy the robot isolation test.
