Communication Trouble

[Jon Stratis]

A few other places to check...

Check the entire power path from the battery to the cRio. There should be no "wiggle" in any of the connections - the battery terminals, the terminals on the 120A breaker, or the terminals on the power distribution board. If any of those spots is loose, it can cause a high resistance which will reduce the power available to the robot, possible causing a cRio reset.

Also check your electrical isolation. The cRio should be completely isolated from the frame, as the case for the cRio is grounded. I've seen scenarios where the cRio appeared isolated when the robot was sitting there, but when moving it would bounce around a little bit, or the material it was mounted to would flex, and it would short to the frame. If anything else is shorted to your frame (like a 775 from last year, or a wire someone accidentally caught under the head of a bolt), you can cause power issues that will cause a reset.
