The hard part with cylinders isn't actually the pneumatics so much as the design of the climbing mechanism. A pair of 1.25" bore cylinders are more than capable of lifting our robot very easily. Due to the climbing requirement, we designed our robot to be under 100 lbs with both battery and bumpers.

Assuming you get a pneumatics design that works for climbing, then you just need to add tanks to ensure you have enough air volume. Our current plan is to have six 41in tanks and the small compressor on-board the robot. We will charge the tanks before a match. The compressor is there to ensure any leaks will not be a problem in the match or while queuing - we don't actually expect it to even come on until we are climbing and consuming gobs of air. The size of our two climbing cylinders far exceeds the ability to reasonably climb with just the compressor itself which is why we need the tanks.
