When LEGO Great Ball Contraption meets LEGO automata world, you end up with an amazing conceptual module, truly mesmerizing to watch. Ball Track Upside Down is one of the latest artistic creations from Diamabolo, an innovative automaton builder coming from Germany. This LEGO MOC can be considered as a LEGO GBC module in closed loop: balls are falling along the ramps of a conveyor powered by a LEGO motor. Thanks to the speed of the conveyor, viewers have the impression that the GBC balls are falling infinitely. When balls are slower to fall than the conveyor speed, a smart mechanism with sides ramps brings them back at the bottom of the conveyor. Let yourself be amazed by the must-watch video from this awesome build on diamabolo YouTube channel
