Why use a manifold?

[Jon Stratis]

I'll add one thing I've seen in inspection... fill all slots on the manifold appropriately! Solenoids attach to them at the top with a rubber gasket to ensure a good seal. If you aren't using one of those slots, either put a solenoid in there anyways (It's always good to have a backup, if you can afford the weight) or put in an appropriate cap that's designed and sold for that use. I've seen teams block unused ports with epoxy or hot glue before, which just means that manifold is coming off the robot when the inspector sees it!
