1024... if you've seen, has an elevator mounted manipulator with several degrees of freedom, capable of scoring on all three levels and changing the orientation of the tube within its gripper. It can also remove tubes from the rack. Nice speedy drivetrain too... software's coming along so multi-mode autonomous as well.
Depending on how many helium baloons we can find (or how good we get at carbon fiber n such), one or two full width ramps....
