What exact do those pneumatic pistons do?

this is kinda stretch, but does anyone have a two or three speed transmission in action on video or something

thanks

The pistons shift gears. Servos can also be used, if you are careful.

I'm sure there are some, but you'd get the whole robot. (330 2007-2008, for example. No gearbox-only shots, but there are times you can tell they shift gears.)
