This gives us twice the amount of air to work with and we still have enough force to lift two robots.

Correct me if I am mistaken, but it looks like the pistons raise your robot as well as the other two? So, given the max weight of a robot being ≈148 lb. (120+13 battery+15 bumpers), wouldn't you need at least 444 pound of upward force? The 4 central pistons each producing 80 lb.s only gives about 320 lb. of force. Even if the outrigger piston is also 2 in. (which it doesn't appear to be) that's still only 400 lb. of force.
Is there something I'm missing?
