It’s really quite simple to get the piston to stop half way. The valves last year worked because there was a neutral position. You can make a similar setup using 2 valves, one single and one double. Hook the double up to a cylinder like you normally would. Now plug both exhaust ports together and send that tube to the single switch. Sine it is spring loaded it will stay in its default position. Put a plug in the port where that air would normally come out. Now when you apply pressure to one side of the piston it will not move because you have effectively "plugged" the exhaust. To allow the piston to move, simply activate the single switch and the air is vented. Get it? The advantage to this system is that when the piston is stopped it is at full pressure, not atmosphere. A quick diagram of this setup can be seen by clicking on the link below. Have fun :-)

P.S. Some people probably are not too happy that I disclosed this information. The way I see it, if I end up being allied with a robot that would benefit from a stoppable piston I have not only helped that team, but have also helped myself. I’m sure there are many teams who have already discovered a way to stop the piston. There are many ways. This is only 1 of 2 that I came up with.
