The on-the-fly pneumatic shifting works by brute force. As the robot is moving, the pneumatic cylinder forces the gear off the current gear that it is locked with (they slide apart), and slides it along the shaft until it hits the 2nd gear. These cylinders have anywhere from 30-180lbs of force (30 is plenty). As the opposing gear rotates (becasue the robot is moving) eventually the gears will mesh and the cylinder will force the gear to slide into position.
I have a question? It sounds like you would shred the gears if you try and force them to mesh as one is moving.
