Painting robots processing a part moving on a conveyor are synchronized by creating for each of the robots a master sequence of computer program instructions for a collision-free movement of robots along associated master sequence paths relative to the moving part, each of the master sequence paths including positions of the associated robot and the conveyor at pre-defined synchronization points, and running each of the master sequences on a controller connected to the associated robot to move the associated robot and comparing a current path of the associated robot and the conveyor against the master sequence path. The method further includes operating the controllers to adjust the current paths based on the comparison between the master sequence path and the current path, and operating the controllers to request a conveyor motion hold as necessary to facilitate synchronization between movement of the robots and the conveyor.
