Re: [FTC]: Edison Division replaying a ton of matches today.

This comes from the words of John Tobes and Micheal Coleman.

There is a very consistent problem with NXT lock-ups which are always caused by static arcing.
Micheal was explaining to me FIRST was running some tests on a NXT lockup issue they have where the NXT completely freezes where there was no drop in voltage or Samantha module disconnect.
This happens when a 8000v~ or higher discharge occurs on the Tetrix Motor Controllers.
There was a discharge/ground cable that was given to us at championship and because it wasn't enforced both sides either using it or not experienced problems.
The people who did use it were at a high state of ground than the people who were not therefore when robots collided with the field or other robots that were charged all the energy was then discharged onto the grounded robot.
