Re: possible solution to the static problem

Split the regionals, put chains on half and not on the other half and then correlate resets, chains, and humidity. If it makes things worse, it will do that for only half of the practice rounds. If it makes things better, it will do that for half of the practice rounds. (I'm ignoring the DS issues - they are a different matter).
Neither static wicks nor drag chains were permitted by the inspectors at the Florida regional. I suggested to them, (and probably others made similar suggestions), that they consider drag chains on the trailers since that could remain completely under their control. Our drivers saw the chains on the trailers on Saturday.

I know that Team 2383 was having reset issues on Friday that disappeared on Saturday. They would reset every time they contacted a wall. This, however, could have been electrical rather than electrostatic.

I don't know if the "Trailer Drag Chains" have been tried at other regionals but it does appear that at least they do not make matters worse on the actual playing field, at least as far as Robot resets are concerned.
