To operate the module, in addition to the parts listed, a battery box for PowerFunction and the balls for playing GBC are necessary. The model will need to be adjusted after it is completed. The adjustment method can be found on page 116 of the instructions (please refer to the YouTube video). The instructions are intended for persons who have experience assembling Lego Technic. You must not copy and distribute the instructions, CAD data, and part lists.

Started: June 2020 Completed: June 2020 Released: June 2020 A improved model of the spiral lift I made before. The pillar that supports the rotor was made as thin as possible. The shape of the receiver has also been improved, so that the ball does not remain. Switching the exit lane direction of the spiral path, the machine can be used as a Independent ball machine or as a Great Ball Contraption (GBC) module. I don’t make instructions for this model at this time.

Started: November 2019 Completed: December 2019 Released: January 2020 I made a great ball contraption (GBC) module using a robot arm. The Type V760 robot has been upgraded, and information on the robot itself is provided here. The robot moves the container, and also moves the ball into the container by lifting a yellow bar. The robot carries one container with 30 balls in 28 seconds, a processing speed that barely meets the 1 ball/sec standard. Because this module is not for an exhibition, but for a video presentation, I have left the ball either stuck or unstable. While this has not been tested, I believe that if you move it for a long time, the position of the robot may shift, and this makes it challenging to display it as it is at exhibitions.

Started: June 2019 Completed: August 2019 Released: September 2019 Instructions are available here I made a car that carries the balls with Adaptive Cruise Control (ACC). I use Lego’s Powered Up platform. This car has a Powered Up hub, driving motor, and distance sensor. I programmed to run while keeping a certain distance from the obstacle.   The car body was made with a focus on compactness. A small body is packed with a Powered Up hub, motor, and distance sensor. This car is small but four-wheel drive.   The loading part was made using a Powered Up move hub. Two motors built in the move hub drive the star wheel and gate. A distance sensor is used to detect the arrival of a car. With the red lever, we can press the green power button on the Move Hub. I used a new part 35446(BrickLink) for the star wheel.
