Pneumatic Systems

Yeah, it's definitely possible to have loads and loads of air storage. The issue with having the tanks outside of your frame perimeter is that in the event that you get bumped by other robots, you're possibly looking at 120 PSI plastic tanks getting hit by the metal chassis of a robot going 15+ ft/s (if you're moving, we could potentially have 30+ ft/s collision). So, I'd be seriously concerned about safety with that sort of setup. While it is quite unlikely that there will be anywhere near as many collisions this year as there were last year, it is still a thing to keep in mind, especially with pressurized systems.

Assuming that issue is solved, I do see quite a bit of potential for pneumatics. You can do the majority of lifting with your cylinders (say, raising between levels with different length cylinders), and then do fine adjustment by having the entire cylinder mounted on a lead screw or something, being able to adjust it a couple of inches as necessary to stack (to go over lips and such).
