New that we've gone off topic, let me toss in the ultimate water game a couple of mentors have been thinking about. It's the sort of water game that Dean is more likely to approve, as well. They'll have to ditch the seven-to-twelve rounds plus playoffs, though.
The game:
Solar Slingshot. Teams build robots which roam the solar system, collecting and purifying water and delivering it to impoverished space stations.
Autonomous: There is a two hour autonomous period during which teams may launch their robot. There is a 20 point bonus for reaching LEO (low earth orbit) during autonomous, and a 40 point bonus for reaching earth escape velocity. Note: teams competing at regionals and districts more than 300m above sea level will have adjusted reaction mass allocations and autonomous scoring. For an additional shipping fee, teams may begin aboard a SpaceX-launched craft in LEO at the end of the autonomous period, thus waiving eligibility for autonomous points.
Teleop: Teams direct their robots to a comet. Robots then mine the comet for water and deliver said water to one of two beacons located at the L4 and L5 metastable orbits leading and trailing the moon. Since the temperature will be below freezing, scoring is by mass, not volume: 1 point per 100g delivered. Maximum payload: 20kg per round trip.
Endgame: Before closing ceremonies, return the robot to the LEO craft for a 20 point bonus or the terrestrial regional for 40 bonus points. The "license plate" must still be intact and (after cleaning) legible to receive endgame bonus points.
