Robot loses communication while going over obstacles

[boz336]

We had the same problem last year. It was a very slightly loose crimp on our battery lug. We thought our wiring was fine.. And the behavior wasn't repeatable when we shook the robot off field... But consistently happened when we drove over the platforms.

You might want to triple check the connections to the battery and/or other power connections that "look" OK, but might be intermittent under mechanical shock. You can always try the shake test... But in our case we still didn't see the problem.

If you really suspect brownout, you can look at the robot logs for battery voltage to see if it gets low.

Very frustrating... Hope you get it solved.

Multiple teams were having the same problem at our scrimmage yesterday including ourselves. We discovered that the bridge power connector can sometimes wiggle loose during a match and cause the bridge to reboot when it experiences some shock from an obstacle. We fixed ours with a ziptie stretching around our bridge to hold the power connector tightly in place.
