Shifting Two Anymarks with One Pistion

It would weigh less than two cylinders probably (Depending on the linkage weight), but I don't imagine it would reduce air consumption like they claim.

Of course! We did that on our robot this year. What was i thinking ... it must be late...

Team 45 was the first I know of to do this, in 2003.

you should check out and see what the total weight of this system vs. two 1/2" stroke cylinders would be. there might not be much weight savings - the small cyliners are pretty light.

Also, you can control them both from one solenoid (which is actually a good design approach so you know both transmissions are shifting at the same time).

You might also be cautious - it is not legal to modify the pneumatic cylinders, and some inspectors might be concerned about the modifications you have made.

48 also did this in 2003 on our 45-inspired dog-shifter design. We also added failsafe springs to force and keep the shifters in gear in the event of a pneumatic system failure.

Simbotics did this last year.
