Re: Thoughts after my first "FIRST" season

Communications between the robot, the driver station, and the field are monitored continuously during matches. Also battery voltage, enabled/disabled status, packet loss and round trip time. Those are the readily accessible items, visible on a screen during the match. With digging more information is available but it is unusual to have to go that deep and there would have to be a specific reason to do that while running matches.

If the FMS (Field Management System) lights are all green and your robot stops moving, it is almost certainly something on your robot or driver station that is causing the problem. But there are many ways this can happen ranging from weak batteries, to shock loading, to poor programming.

In LA and AZ we kept logs of dead robots and had people delegated to track down the real issue any time a robot died in a match. While I think we had far too many, all instances were ultimately traced to either team hardware or robot programming.
