I mean, in the past when we were told we couldn't use it, its not like they made us take the ability to pressurize from the cart away, they just asked us not to use it, because of the rule violation.

Setting up the cart to follow the rules to the letter is NOT a difficult thing to do. All that is needed to do it is a little planning:
1) One additional shut off valve on the robot with a nipple in it to connect the tubing from the compressor..
2) Easy access to the load side of the Spike feeding the compressor so that the connections can be made and removed simply.
3) A short pigtail connection from the limit switch so the signal into the cRio can easily be connected/disconnected.
The 125psi relief valve would stay on the compressor as the rules require and save a bit more weight.
All of these connections could actually be done through one modular connector with the exception of the pneumatic tubing.
