About how much weight can pneumatics pick up when retracting?

It’s the “air cylinder” that retracts…the term “pneumatics” applies to all the components…and most of your colleagues incorrectly call the air cylinder a “piston” (which is just a very small moving part inside the air cylinder). Here an article with lots of useful information, including the answer to your question: https://kb.vex.com/hc/en-us/articles/4404197704212-Getting-Started-with-Pneumatics-with-the-V5-System#calculating-force-of-cylinders-TjH7s

If you need more force than the air cylinder can provide, you can design mechanisms to increase the applied force (at the trade-off of less motion).

More about terminology: If we're going to call an air cylinder a "pneumatic" then we should call V5 motors "electrics"!


I know this might be dumb to argue but I personally call air cylinders pneumatics because pneumatics for me is simpler to say than air cylinder and the point of making new terms for things is to generalize or simplify things, so arguing calling motors electrics is not comparable to pneumatics and air cylinders. but like I said above this is nothing but my opinion so feel free to disagree!

Look out… its the beginning of the season, and kmmohn needs to clarify this point again. Best to accept the facts and not be sloppy with your verbiage.


@kmmohn is 100% correct here. Use the forum as a place to learn and improve your skills, including communication and a learning the jargon of the industry. One day you may be sitting in an interview with a firm for a summer internship and using the correct words will improve your odds at landing that internship.


I absolutely 100% would support this initiative!

My mother says that staring all day long at electronics, and reading the antics of pedantics on the online resources for robotics, with pfps resembling anime anthropomorphics, is not as useful as joining the aquatics or doing aerobics / acrobatics to have a shot at school olympics.

But everyone from water game fanatics to recent PhDs in mathematics, who look at forum analytics, could easily persuade dogmatics, that one of core characteristics of evolutionary linguistics is to acknowledge that studentics enjoy inventing word nonsentics with sprinkle of the odd grammatics, that tends to drive insane pedantics.

And while for some, according to statistics, words like “electrics” and “odometristics” may come across pig latin or as weird anachronistics, I find them having many good utilitaristics. Please, add me to the camp of optimistics, who work to optimize the lingual logistics for benefit of homo futuristics.


@Illyana I love what you said here! :heart: I am joining you in this!

Something of note is that the article gives the force a single air cylinder can output, under ideal conditions at 100 psi (gauge pressure). Variations in pressure (such as non-perfect pneumatic seals, and loss of pressure over time as the cylinder(s) actuate could reduce the force of the cylinder. It might be helpful to test the force a cylinder can exert, if you are able to easily do so, before designing an entire robot around the theoretical force given, especially if you are uncertain how much pressure the system will have at the time when you are retracting the cylinder.
