Agreed, but from the reveal, the robot only appeared to be using 12 motors. That leaves 4 motors for a flywheel and chain. Or maybe that robot will only shoot from the starting tile, so it won’t need a chain or an intake. In any case, you’re right that a purely elevating robot would be bad, but the 24 inch robot still had plenty of motors to shoot with.
Separately, have you guys considered using any sort of 3D printed catapult or something? Printer plastic is lighter than a C channel so its good material for a catapult.
