Actually i need just a small amount of force. I need to push something that ways like 1/8 of a pound and is like6 inches long. Sort of like how a cd tray goes in and out. In fact exactly how a cd tray goes in and out. But i need it to be able to poush many things like a row of things.
Think of a cd copy tower how there are many cd burners(trays) that open individually but i need them to all run on 1 arm. Like 1 motor controls up and down (location) of servo/hydro.. and the servo/hydro.. controls in and out. from that location
