Re: Pneumatics - what do we do with exhaust air?

After I posted, i realized that you would need check valves, therefore making it much more complicated (and i do believe unusable since i don't think you can use check valves on the robot)

Unless you want to work another downstream cylinder at a lower pressure, and set up an elaborate system of check valves and pressure reliefs, you can't get more work out of the exhaust.

Let them vent, and don't even worry about putting fittings on - save the weight.
