Robot losing and regaining drive power

[Al Skierkiewicz]

PSH,
Just to add to Kevin's response, problems with going forward and not backward can also be mechanical in nature. Do you have slack in your drive chains and is the slack enough to throw a link into an adjacent mechanical frame member? If so, that would explain backing up and then having a problem again in forward. Losing power in turns is an age old problem with tank drives and high friction wheels. It is why most teams either use omni wheels or drop center drives to overcome the side loading of the wheels in turns. For reference...

Less than one second (stutter) is branch circuit breakers tripping usually with buzzing sound from robot
Less than one second with all lights blinking off is a faulty main breaker usually follows a robot collision or other mechanical event
3.5 second with power is Jag reset from over current/under voltage fault
20-40 seconds is Crio reset usually due to battery brownout
52 seconds is DAP-1522 reset usually due to battery brownout
Disabled for the remainder of the match with power, could be a failure of the Crio and DAP connecting once reboot occurs
Disabled for the remainder of the match with no power showing, is main breaker trip (highly unlikely)
