Reminds me of the last team to pass at Arizona this year. They'd been trying to fix their pneumatics, they had a match coming up, and they thought they had it. Two inspectors (myself being one) were inspecting their robot, and each had one gauge. They power up...and both gauges read 120 PSI! OK, let's dial it down to 60 PSI, guys. They did--and both gauges read 60 PSI. The first place we looked for the problem? The regulator. Sure enough, the input was going into an output, and I think the gauge was in the input slot--in short, 90 degrees from the way it should have been oriented. With a match coming up, we had them pull the compressor breaker. They later got their pneumatics working right and reinspected.

Oh, and another team had pneumatics--but had no vent valve and no relief valve. Uh-oh. The next time they came around, they had both.
