Re: Official Team 2526 Robot Model!!

You'll be very disappointed with multiple positions using pneumatics. Also remember that gases compress, so if the load on the piston changes, it will move.

It can be done, however, with a double-solenoid valve (3-way), which is an off-the-shelf item. We used the gray solenoid valves, not the blue Bosch ones, and special-ordered them. No need to fool with two solenoid valves and fancy plumbing to modulate the exhaust port....
