Stuart, If they can make any kind of a rolling robot and program it to move forward and stop, they can complete three missions: push a ball into the reservoir, trigger the storm, and push a minifig to the green mountain. With those plus the three gimme levees (assuming the storm doesn't clobber one), that's 5+15+10+15=45 points right there. Maybe they'd find that fact encouraging. And the penalties are taken from the levees in Base, so that score holds even if their robot doesn't drive backwards back to Base and is retrieved by hand each time.
