Yes, I really did.
No, not exactly... but I think I have it down.
Not leaving time, after the bot is done, to practice driving before practice day
Being unrealistic about how much can get done in 3 minutes
Not basing all decisions on strategy-- and/or not using scoring/feasibility to create strategy
Being "fair" by having students who haven't spent time studying the math behind the scoring have just as much say on strategy as the students who do understand the complexity of how the scoring works.
Using overly complicated programming/design/mechanical strategies
All of the above
Core samples, assuming a 45 second drive each direction, 25 second pick up, 20 second drop off
Chalcopyrite bin (full), assuming 40 second drive each direction, 25 second pick up, 15 second drop off
Filter replacement or pipe replacement, assuming the robot only picks up one at a time and each is a 35 second pickup, 35 second travel (each way), and 55 second placement
As much aggregate and all the coal you can get, assuming 10 second travel time per piece (yes, that's and unrealistically speedy bot!).
Before semi-finals, based on seeding matches
After each seeding match, based on previous match
Before finals, based on semi-finals
During game play, based on what each team puts into their bins
Coal because even though it scores fewer points than the bauxite in the seeding rounds, the deflation of the bauxite makes the coal more valuable.
Coal because because other teams will also be going for the coal this time.
Bauxite because market values will now be higher for bauxite and lower for coal.
Bauxite because it scores higher than coal.
