I tried searching for this. On youtube and google you can find a lot of examples of linear actuators being used to open and close doors. I have a door of 40cm high (for a robot mower to pass), but how do i select the width for the rod of the linear actuator, and where on the door do i have to fix the actuator?

Any help to how i should make this is welcome.
