Robots not under driver control- does it happen- do you determine why?

[Kevin Sevcik]

You know, I'm not certain if it's always the same jag. It was doing the slow yellow disabled blink and we couldn't see it on the CAN bus, until we cycled power on the robot and everything was fine. I'll tell our programmer to note which jag is causing the problems the next time it happens and we might just swap it out for a spare one if it's the same one.

Related note: was your problem jag a black jaguar on your drivetrain or another system subject to sudden heavy current reversals? The gray jags have issues with sudden reversals blowing up gate drivers and disabling half the h bridge. Perhaps the new ones are subject to some other, more unlikely sort of failure when hit with a sudden reversal.
