>>10250552Could just have two thin arms that ride on top of each other that fit between the doors and the server outside the receving container where nothing can touch it. The arms could have a little Y shape to hold both sides of the doors and slide together to open the bays and apart to close, and have a seperate servo to raise and lower them. I could probably use some cheap airplane servos to do the functions, the only hard part would be figuring out the programing or mechanical limits to make the servos only move a little bit. Maybe I could use some ez track switch motors since they have an open and closed state, and its basically the same thing. I'm still brain storming it.
