Re: cRio Constantly Rebooting
I am willing to bet it's the 6 motor drive, combined with the additional current draw of a drivetrain being pushed against and pushing. We did some magic math at the beginning of the season and found that heavily loading all of those motors would lead to pretty quick battery drains (1:30 or so into a match with some other mechanisms running).
Talking to some friends with similar issues, changing the 6 motor drive's gearing to a lower speed (10 FPS is apparently a good sweet spot) made the issue go away entirely. From what I can recall, you guys are running at 13 FPS, which is much heavier on the motors.

...I tried to pump it up to the 47 inches. I stopped around 42 inches, than tried getting it through a 36" door. It got stuck, I proceeded to dropkick the thing in front of my team and a girl I had gone out with the previous Fri. It didn't move, I hit the floor.
Ouch, my pride. - ChrisMcK2186 [more]
