I was tired of looking at the confusing FIRST maps, so I built myself a small Android app that works entirely offline and (as far as I can tell without extremely rigorous testing or being at the event in person) gives directions for paths between pits between any two team numbers. I figured I’d share it with the community, if anyone else wants to use it:
