General Pneumatics

[Drok00]

okay, this is our first year working with pneumatics, and were unsure if the pneumatic cylinders can move in and out slowly i thought it could be moved in and out slowly if you just adjusted the pressure, but then another problem arose , can pneumatics be like in between in positioning? like at the halfway mark?

yes, pneumatics can be moved in and out slowly, just by playing with the flow controls, which are usually screwed into the cylinder. And about multi-positioning of pneumatics, there was a big discussion last year, you might want to just read that thread.

I'd say in addition to the advice posted above the best way to learn about the pneumatics is to play with them. Set up a board with everything mounted on it and get some code on the controller that can turn things on and off and see how everything works, this will save you alot of time when you go to put all of your pneumatics in the robot.

You should also go to www.pneumaticsfirst.org/ This is site has a lot of useful information, and make sure you read the 2005 pneumatics manual. Also, when using pneumatics, to learn, be careful as they can be very dangerous.

cool thanks for the help everybody!!

Check out the thread below, "Pneumatic Confusion", for answers to a similar question.

Also, (and pardon, I have not read through the other posts yet), it would be worth your while to check out the magnetic sensors available with this years cylinders, but remember, you have to specify them when you order.

if anyone wants help with pneumatics cicuits and wutlike feel free to pm/im/email me since i seem to not be in a team this year i can help anyone who needs it in depth without worrying all about MY team. i understand the concept and have mastered multipostioning but have yet to figure out the magnetic sensors as we have never used any.

I would be interested in how you did multi-positioning, we have traditionally had "creep" in our systems, that is why I am puching for magnetic sensors this year . . . or, go totally overboard, and use shape memory alloys and terfelon-d, no pneumatics.
