They did another test drive today, and jokingly said they should name it "zippy" because it goes plenty fast. I even
got to drive! after they'd run the batteries down, driving it around for over 20 minutes. That's with two VEX NiCd batteries wired in series, giving 14.4v nominal and 2000 mAH. We're thinking of just getting some 3500 mAH NiMH battery packs and it should provide plenty of power for the mission.
They've worked out a list of parts to buy to build two more robots...this will be fun!
The LEGIT robot is looking good! I hope they can get it in the water early and get some good practice, it really helps.
