As one of those FMS guys poring through the logs, I think (and will verify with FIRST) that the battery voltage being reported is not actually coming from the robot but instead from the classmate. I now think the classmate is reporting the last known voltage it saw. The FMS shows the change in status pretty much immediately when the robot loses its link to the field. At the scorekeeper table, we're constantly monitoring this and when we see it, send the FTA to look more closely. Sometimes it is obvious. When we suspect an issue, we try to get someone to pass the word to the team to look at likely causes. There are a lot of electrical connections on current FIRST robots where any one bad connection can take you down for a few seconds or an entire match.

The match could not have started with the breakers on 34 or 1311 being open. Something clearly happened to both.
