Our team has little experience with pneumatics, and we want to get some during the off season. We would like to use a pneumatic actuator in situations where electric motors are too slow, not strong enough.

But is it possible to move an arm, for instance, to intermediate positions like you can with an electric motor? Or does it have to be all the way up, all the way down.

If intermediate positions are possible, can there be a continuous range? What type of control systems do you need?

Any advice about this would be much appreciated. Any links that would be helpful?
