ROK Works is the most popular way of starting a Rokenbok World. It's fun and challenging to build to the included plans, and there is a lot to do once everything is up and running. We made it easy to add to this set; the ROK Lift, Forklift, and Monorail just snap right in. The ROK Star Controller that comes with ROK Works will control any Rokenbok machine, too. Designed to be a home base, this set is the best starting point for anyone looking to create a dynamic, expandable Rokenbok world.
