I have been wanting to do some experimentation with some linear actuators and I am looking for some advice on how to control the actuator position. I am looking at using an actuator with two air inlets and a lift/pull capacity of 150 pounds.
I have been looking at Automation Direct for components, which is rather the easy part. Finding the device to control the actuator the way I want seems to be the hard part.
What I want the actuator to do is move the shaft proportional to the air in the cylinder. Think of a hobby servo whose position is based on the pulse width of the control signal applied. That is what I am looking to do.
the goal is to have it controlled by an AVR, but baby steps forst.
Has anyone done this sort of thing?
