This GBC Ball Dozer is entirely built using only parts from the LEGO Liebherr R 9800 and can be referred to as Alternate Build of the 42100. When building this GBC Ball Dozer it makes sure you master interesting building techniques and tricks so that you eventually also can build your own GBCs. The whole machine is powered by 2 LEGO motors which comes with the LEGO 42100 Set.

Build and control this fun little GBC Ball Dozer and push the GBC Balls across your entire room. This machine is part of our GBC 41 Power Pit Mania – 42100 C Model which makes a great GBC Ball arena for this little guy.
After building the GBC Ball Dozer you can control the machine using the default official LEGO Powered Up App (Available on smartphones/Iphones/tablets/Ipads) and choose a profile like the Batmobile interface or use the Create interface. Plug and play, easy and reliable.

 

Fun Fact


Having the control over 2 separate Control Plus hubs (which are included in this LEGO set) really got us thinking from the very beginning how to implement this power into a unique and fun concept. Many ideas raised from remote GBCs to multiple collaborating GBCs. However we were very intrigued by the idea of the builder being a part of the GBC after he/she has build it. In the end we settled up on the idea of having a GBC Ball Dozer pushing the GBC Balls around which can interact with the environment it is in. A warning from the designers: It’s very addictive to keep playing with the GBC 41 in full operation!

  1. Jean Bernard van Hoorn –

    Nice little car which I think looks really cute. After this car I build the GBC 41 where this car belongs in. So much fun pushing the balls forward and being part of the gbc machine. Also very clear instructions and you should definitely try the gbc 41 Power pit Mania after you finished this.

Software - The easy way


After building the GBC Ball Dozer you can control the machine using the official LEGO Powered Up App.

LEGO Powered Up App

Control the GBC Ball Dozer using the official LEGO Powered Up App, available on Android smartphones, tablets, Iphones and Ipads. This allows you to create custom software and add a user interface which is carefully explained in the building instructions.
After you have some experience with the software we encourage you to modify our software and make it your very own. What new features and functions can you come up with?

Download and install the LEGO Powered Up App for your smart device:

If you don't have the required LEGO set there is still a chance you can build our models by using parts you already have. Most technic models use a lot of the same and/or replaceable parts. When watching the video and checking upon the building instructions you can easily see which parts can be replaced if you desire so.
What cool color designs can you come up with?!

Optionally you can also directly import the part list to Rebrickable. Some warnings may pop up during importing due to part/color number inconsistencies between databases. Most of the time these are not to worry about and Rebrickable will give you a nice overview of it.
