This looks like something that would chase me in my nightmares.....

Looks like the only thing you are missing is a fuel tank.

I see pneumatics too...

Due to how inventor utilizes "segments" in building constraints and my unwillingness to route a black and red wire seperately for every connection, I did the following. Under the segments are true black and red wires of correct gauge. The power side of wires is covered in "red chrome" material while the motor sides is a "black chrome". The battery leads are left normal, pwm's are covered by gold material and then the pneumatics is all the orange and very thick "wires".

I see a few issues here. The first is that you have 2 power converters, neither of which is hooked up to the regulated 12 volt output on the PDB. The wireless bridge should be run off of one of the 12 volt regulated supply via one of these adapters to avoid communication drop-outs. The second thing is that your compressor is connected directly to a hose after the check valve. after the check valve should be a tee with whatever you want on oneside, and the pressure relief valve on the other to satisfy [R75]

[R75]
The relief valve must be attached directly to the compressor or attached by suitable brass fittings connected to the compressor output port.


If necessary, teams are required to adjust the relief valve to release air at 125 psi. The valve may or may not have been calibrated prior to being supplied to teams.

That sound you just heard was my husband fainting dead on the floor! He is a master electrician and if the kids don't wire just right, it all gets done over again until it is a thing of beauty!

yes, some parts especially the power convertors are very incorrect, but very difficult to see that, they are infact plugged into the power distrubiution board, and to answer your question the pneumatics is in fact correct, if you trace it, the compressor goes directly to the storage tanks, then goes to the Tee on the Norgren (on one side) and to the pressure relief valve on the other side. After the Norgren are the actuators. You see the compressor going directly to the valve which is not the case it actually snakes underneath that black board to where the tanks are placed then back through the proper system. The wiring on the DC convertors is being fixed, the ribbion cable is being mounted, the classmate, pot/encoders, and solenoids are being wired tonight.

If in the process of plugging in a wire you jostle loose three others, reexamine what you did to get left with the crappiest and smallest place on the bot to mount electronics!

The relief valve MUST be connected to the compressor by only brass fittings. The tanks are not brass fittings. The relief valve must be before any hoses, tanks, valves (except for the factory installed check valve), or regulators. The check valve is the small hexagonal piece directly mounted to the compressor. This is allowed since it is factory installed, but every thing in between this component and the relief valve must be BRASS.

now I am really confused, This is what first puts as their diagram...

That is going compressor, storage tanks, relief valve/ regulator....

Any clarification would be great.

You've got the dump valve confused with the relief valve.

The relief valve is the small brass thing on top of the compressor in that diagram. The relief valve prevents the pressure from going too high; the dump valve is used to drain all the air out of the system.

yeah I just realized that, on the old compressor model I was using it was already placed on the output of the compressor, and I didn't even think about it on this one. Yes it is done correctly on our robot, but I made a mistake on the render, luckily you can't see it on the whole render

The relief valve must be attached directly to the compressor or attached by suitable brass fittings connected to the compressor output port.

In the pictures/diagrams that you linked to the pressure relief valve is directly connected to the compressors secondary port.

I believe you may be mixing up the pressure switch (which must be on the high side) and the pressure relief valve (which must be hard connected to the compressor.
