So as many people have said, it has been a while since pneumatics were used, and many people have not used them at all. So I created this thread as a way where those who have used them can share their knowledge of them, as well as other resources.

This tutorial is very easy to understand and is a good intro to vex pneumatics. [VEX Pneumatics Components] More over what each component does. [image] Pneumatics Frankly this is just a lot of hot air... Pneumatics are very simple if you know h…

I feel like the community should learn about the vocabulary of pneumatics: [680px-Pneumatics_Kit_2_Annotated] Both single acting and double acting cylinders have two modes. Single acting: Mode 0 - Off Mode 1 - Push outwards Double Acting: Mode 0 - Push inwards Mode 1 - Push outwards This wi…

[image] anon4126930: double acting will use a whole lotta more air than single acting, so choose your cylinders wisely! To elaborate a bit more on the difference, double-acting cylinders use air to both extend and retract, while single-acting cylinders use air only to extend, and have an inte…

This is usually weaker than the extension force. I don’t believe there is a hard and fast rule, it really just depends on what spring the manufacturer uses in the cylinder.

Pretty fast (it’s spring loaded) but not powerful enough to do anything useful. You can increase the retraction speed and force by adding rubber bands, but now you’ll need more air to extend the cylinder. This is the advantage of double acting cylinders: you can set the retraction force as need…

How do you know which one is which without testing them

If the cylinder has a port on each end, it is double acting. If it only has a port on the end away from the piston, it is single-acting.
