Depending on funds, and if i were king for a day:
Phase 1: Build a hacky robot. Make it reliable and functional, but not polished or perfect. It plays to a certain strategy and that is all. A very specialized robot. Drive it like crazy, practice for hours. Make the students of the drive team avoid eye contact if you see them in the wild, ie, not driving. Go to a week 1 event. Win?
Phase 2: Have students watch matches religiously. Maybe send a student or two to regionals far away. Have them copy and clone the very best of ideas and strategies.
Phase 3: Implement said ideas into the second robot you were building on the side, that you continue refining and building during basically the next 5 weeks after the “old” season would have ended. Have just some basic functions done during the “old” build season. You now have twice the build and drive time.
Phase 4: Go to week 5 and 6 events. Win, hopefully.
I’m not sure how this helps teams with a limited budget though, as this rough plan will make upper mid tier teams crazy good, and who knows what the poofs will look like at worlds.
