Question about things that MUST be on the robot w/o compressor

[EricH]

Nothing says you can't that I can find; you'll want to put a fitting in so the connection doesn't leak.

(Of course, my opinion is not necessarily valid at inspection; to be sure, ask Q&A.)

I want to ask but they are now close for new post...

ic ok thanks

Here is the applicable rules concerning on and off board compressors.

<R75> Compressed air for the pneumatic system on the ROBOT must be provided by one and only one compressor. This compressor may be either the Thomas Industries compressor from the KOP, or an equivalent compressor that does not exceed any of the KOP compressor performance specifications (specifically: 12v, 0.8cfm flow rate, 120psi continuous pressure, 120psi maximum pressure compressor). Note: if an alternative compressor is used, during inspection the team may be required to provide documentation to show compliance with the performance specifications. Compressed air shall not come from any other source. The compressor may be mounted on the ROBOT, or it may be left off the ROBOT and used to pre-charge compressed air in the storage tanks prior to bringing the ROBOT onto the FIELD. Off-board compressors must be controlled and powered by the ROBOT.
<R76> “Working” air pressure on the ROBOT must be no greater than 60psi. All working air must be provided through one primary Norgren adjustable pressure regulator.
A. All “working” pneumatic components (e.g. valves, cylinders, rotary actuators, etc.) must be downstream from this regulator.
B. Only the compressor, relief valve, pressure switch, pressure vent plug valve, pressure gauge, storage tanks, tubing, and connecting fittings may be in the high-pressure pneumatic circuit upstream from the regulator.
C. Pressure gauges must be placed in easily visible locations upstream and downstream of the regulator to display the “stored” and “working” pressures.
D. If the compressor is not included on the ROBOT (under the provisions of Rule <R75>), the regulator may be located on-board or off-board, provided all other pneumatic rules are satisfied. Note that if the regulator is kept off-board the ROBOT with the compressor, then only low-pressure (60psi or less) “working” air can be stored on the ROBOT.
<R77> The relief valve must be attached directly to the compressor. If the relief valve is already set to 125psi, teams are not allowed to adjust it. If the relief valve is not set to 125psi, teams are required to adjust to release air at 125psi. The valve may or may not have been calibrated prior to being supplied to teams.

All components except the compressor must be on board the robot. If the regulator is off board, then the robot can only be pressurized to 60 psi.

Hope this helps.
