Pneumatics off board recharge packs

I am going to assume that your goal is to fill the tanks on the robot and that you started with the tanks on the pack full before connecting it to the robot. The air stored on board the pack will spread equally through out the system and drop in overall pressure. Then you would have to leave it connected with the compressor running until not only the robot was full, but also the onboard tanks. I believe that it would take an equal amount of time as without tanks to fill the robot, therefore it is unnecessary to have the tanks.

My guess would be, since it's not controlled by the robot (once again, <R69>), and thus not limited by the pressure switch, they fill those tanks beyond 120psi. They probably use that final pressure regulator to ensure a 120psi fill into their on-board storage.
