I have only a little to add to the above. My key points:

Tell them what to do, but not how to do it. ("Come back over the moat", "There's a boulder to the right", "head for challange")

I watch the dashboard/drive camera during certain operations, mostly to be sure we are close enough to the Cheval, and to say when the vision tracking error is small enough to shoot. These are both being improved for the next event so i can watch the field.

Running to the other teams and checking on status if someone is stuck, or seeing why they aren't moving

Final queue checks for loose wires, etc.

last person to touch the bot on setup. Alignment and setup issues are my fault not the student's.

distributing/reinforcing the game plan during team intros ("Auto will cross the moat, in teleop, we take the shot, then Cheval, low goal, Cheval, low goal, Moat. High goal if there is time. Team X is doing the low bar and rock wall, we are cleanup if something goes wrong.")

Explaining to the spectators (stand drivers) why we did what we did, or what was the view from the field ("Why didn't you just shoot sooner?" "The camera was blocked and the shot would have been no good")

In build season, every team operates differently. On the field, every coach operates differently.
