How do you control the length a piston will extention/retraction?

Hi,

I would love to see sketches or photos of any of the multi-valve solutions. It would be fun to try them out in the lab to learn more about pneumatics fundamentals.

Here is a thought on the KoP. It seems to me that FIRST tries to use equipment that is relatively simple and general rather than highly specialized items. The basic elements of robotics - you might say. I guess it also depends on the cost of the items in question. Does anyone have a sense of the comparative costs of regular versus specialized pneumatic components?
