I think the size of our cylinders is what lead to our issue. They just use a lot of air per stroke. Our high CFM solenoids may also play into this issue.

We also have a pneumatic lifter, and we ran into a lot of problems with air usage, but we have determined through testing that 7 black clippard air tanks (1.1 gallons) was enough to last a match. 7 gallons seem like overkill, but I guess too much is better than too little.
Our initial in house tests were done with 7 black Clippard air tanks and we ran out of air really fast as per my observation. We thought we calculated a fair amount of wiggle room with a 5 gallon air tank. Which it would get us by. However the advertised 5 minute charge time of said air tank with the 250C compressor was not what we were seeing in practice. So we've had to consider what our options are.

The re-do of our lift movement system should be fairly simple. We'll just have to see if we can get it done with enough time to spare to get some more practice time in.

Looking good! That recycle container auto would be great for an alliance partner like us
We made that function of our robot a top priority since day one. We hope to see it pan out well for us in playoffs/eliminations.
