Controlling pneumatic Cylinder on a Joystick?

Hi,
My team wants to use a pneumatic cylinder to control the angle of the shooter and they want to know if it is possible to control it on a joystick so you could for example tell it to go 35% of the way out. Is this possible? Is it a good idea?

Any help is appreciated!

It’s technically possible to give air slowly to a pneumatic cylinder and stop when it’s where you want it to be.

It’s not a good idea, especially for something that will be bearing much of a load. It’ll be springy/bouncy at best. Pneumatic cylinders aren’t great at holding a set position that isn’t at one end or the other of their travel.
