Re: cRio Constantly Rebooting

Interesting - I was watching the Waterloo Regional feed, watching 2056 score twice in autonomous (very impressive!) before dying shortly thereafter for about 40 seconds. I wonder if this was the same issue?

As an update:
* We received our tool crate from Florida, and began doing diagnostics on our electrical board. We have been unable to find any debris, loose connections, damage, etc., to which we could attribute the problem.

* We did notice that with our practice robot up on blocks (wheels off the ground), slamming the stick from full forward to full reverse did cause a (predictable) brief but severe drop in battery voltage. Other than simply asking too much from our battery, though, we're almost out of theories.

* This still begs the question: why didn't we see the issue in practice? Or on practice day or the first half of Friday of our first Regional?

* Lastly, we looked at video of each and every time we died on the field. I see no real pattern - sometimes we were lightly bumped, sometimes we were turning in open field, sometimes we were picking up or carrying a tube. I was able to tell that our RSL DID go out completely each time, meaning that it was the cRIO (and NOT the radio) that was doing the rebooting.
