You’ll love to replicate the latest entry in the GBC4ALL series! The Robot Arm ball machine designed by the LEGO GBC builder Phi. L is equipped with an amazing articulated arm with incredible rotations. Thanks to a sophisticated gearing system, the central arm of this GBC module collects the balls in the reception bin and takes them to the top of the machine. The balls then go down a spiral staircase to the exit. As always with the GBC4ALL modules, this LEGO ball machine is easy to build with children, easy to motorize or to connect with other GBC modules of the series, and is made of easy-to-obtain LEGO TECHNIC bricks. The ingenious mechanisms of this Great Ball Contraption module will fascinate your children and teach them some basic mechanical concepts. Don’t wait any longer and discover this compact little GBC wonder through the ready-to-build kits available on Planet GBC.

wondering how many balls are included when you buy this as a set. The balls in your pictures are coloured differently than Lego has ever officially produced. Wondering if those are the balls that are included(if so, how can you claim your set is 100% official lego?).
three LEGO balls are included in each GBC4ALL sets.
Balls are orange or white (depending on the set) and are genuine LEGO balls (respecting the rule about set 100% official LEGO)
In the videos, I indeed sometimes use Quercetti balls, a cheaper alternative to LEGO balls (on Amazon: https://amzn.to/3gcZFGx).
I do this to have a better contrast in the video editing.
