I am trying to create a vertical gantry system that has two robots on each side. Since I could not have two robot bases moving at the same time on one vertical beam. I made two mechanisms on top of each other that move separately. My problem now is how can I make both of the vertical beams in sync so I can achieve two robot mounts moving along one vertical beam? Each Beam is already synchronized with the two robots. Attached is screenshots of my work space.
