Current auto mode that is selected,
Visions information / camera,
Pneumatics psi,
Red / green status box if robot is connected,
Make sure the actual driverstation is in view as well to see if controllers are connected.
Anything else is clutter and not that useful in a 2:30 second match IMO.
i wasn’t looking down, i was looking at the robot. the operator agreed. it helped that we had LEDs that would go solid green when we had a game piece, and would turn off when we lost it. we had some info displayed that would help our drive coach see what we were doing though, a dashboard using shuffleboard. used it to select our auto too.
as a programmer: everything.
at home, you should be logging literally everything. we used glass to view and graph everything from encoders positions, motor outputs, estimated pose, and more. so useful for tuning PID.
