This is by far our most complex electrical system ever, with 10 motor controllers, two PCM’s, 7 double solenoids, 10 sensors, 4 cameras, and a fancy battery voltage readout!
some of the talon connections are still WIP, so cut us a little slack

I spy two hats!, but seriously your setup looks really nice.
How does the battery gauge work?
EDIT: Just noticed, please never leave both battery terminals exposed at the same time. A unknowing student or metal object (e.g. a tool) could easily complete a very dangerous circuit!
EDIT 2: Also noticed that I can see that you have plugged at least one side of a pneumatic manifold’s exhaust. If both sides are plugged, I would imagine that your pneumatics wouldn’t work. Did you do this purposefully? My team ordered some sintered bronze vents to let the ports vent while remaining protected.
You’re definitely right about the battery! still working on a safety culture here…
The battery gauge is this product, connected to an arcade button from adafruit. You can see it panel mounted on the right of the board near the VRM. We connected it to a wago on the PDP with a 20 amp breaker. It only displays voltage when the button is pressed, so it isnt using any current during the match (it should be insignificant to leave it on all the time, but the button looks cool ;))
One thing I would caution you about if you are interested in using this voltage readout though: The gauge considers ‘low’ battery level to be like 0-1V, while we know the robot would be browning out at 8 or 9V. Basically your battery is dead if the gauge shows anything less than 2 bars from full.
