It has never been easier to build a complete Great Ball Contraption (GBC) loop yourself! GBC 23 features a handy cool module which can be put up for a lot of uses.
This GBC is entirely built using only parts from the LEGO 31313 MINDSTORMS EV3 set or LEGO 45544 MINDSTORMS EV3 Education set and can be referred to as model C of the 31313 Home Edition or the 45544 Education Edition. This GBC makes sure you master the GBC building techniques and tricks so that you eventually also can build your own GBCs.
Play with programming and automate like a boss!
GBC 23 features an advanced and accurate GBC ball detecting and sorting system to use in all your GBC loops.
With this hardware setup a lot is possible and it gives the user a lot of flexibility to eventually come up with your very own awesome rocking code!
The main features are:
- Light Sensor: Detects the GBC balls and can detect ball color difference. It also detect when no GBC balls are present.
- Ball counter motor: Takes for every revolution (and with great accuracy) only one GBC ball out of the ball input box.
- Sorting motor: Reacts on the result of the light sensor readings.
- 2 sort out trays: Holds on for the balls after they are sorted out. When 5 balls are sorted out in one trays it will automatically empty itself and release the balls back into the loop.
- Ball return motor: Picks up the balls after they are dropped by one of the sort out trays. Then brings them back to the beginning of the Module. In this way GBC 23 is self contained. When using GBC 23 in a GBC loop you can choose to exclude this motor.
- Touch Sensor: Acts as an limit switch and tells the “Sorting motor” where it’s homing position is. Advanced Mechatronic Systems always use a setup like this to prevent failures.
- Screen: Displays the number of sorted balls for each color (orange and white).
The default program for the EV3 acts as an advanced GBC ball color sorter with multiple outputs. The full program flow with much more detail is explained in the program it self. Understand our code and start playing yourself by adjusting variables, enabling/disabling functions and eventually come up with your very own awesome rocking code! This all makes it great addition for FIRST® LEGO® League events where teams can compete with each other to make the best Robot. Add other GBC Modules to make the loop complete and create a never ending ball flow. We have some great GBC Modules which serve in handy.

The building instructions are clear and the building process is pleasant as always . There is no apparent issue with the program. However, i did not manage to run a complete cycle of the GBC even once. Hence the three stars. Sorry to say that, but I could not make this GBC reliable. The sort trays depend on the weight of five balls to drop them onto the return basket, which does not happen most of the time. If just one ball falls off, the entire mechanism goes awry. Then the return basket is too small and you have to make sure it does not entangle with the cable for the B motor. I rebuilt the entire model and tried several counterweight for the sorting tray and adjustments for the return basket, to no avail.

Nice module. I created my own code. How can I send it to you?
