As I understood it, pneumatics work by controlling the releasing of pressurized air to manipulate movable pistons which when they become pressurized, expand.

But is the process controllable enough to be used on something that needs a great deal of prison and control, such as a joint in an arm? Can you acurately control the joint of the arm or would it only have one of two extremes? Please help.
Pneumatic cylinders are very controlable with the use of the flow controls in the kit. They control the velocity that the cylinders move at. I would not suggest trying to use them in a situation where you need three or more positions. The first is all the way retracted and the second is all the way extended. Fred Hord
