Ball Rolling Machine 18 is another awesome LEGO GBC module from Rimo Yaona.

The main mechanism from this massive Great Ball Contraption is standing straight in the middle of the machine: a massive tower holding two sliding arms with fix buckets.

The synchronous alternating moves from the two arms is progressively transferring balls from one side to the other of the central tower thanks to static axles pushing them to the center of it.

GBC balls reach the top of the module and slide to the exit ramp from this sophisticated LEGO ball machine.

Even though the moving tower takes all the spotlights, the front part of the module is also a kind of GBC module on its own with a stepper and a creative ball feeder.

You can now watch the stunning mechanism from your own copy of this amazing marble machine thanks to ready-to-build LEGO set available on BuildaMOC.
