Great Ball Contraption (GBC) at Japan Brickfest 2016

Featured at Japan’s Brickfest 2016, this Great Ball Contraption is made of 20 modules created by four designers: 3 modules from Finn, 2 from Toise, 1 from Y. Kuramata, and 14 modules from Akiyuki, who is famous for creating ball contraptions like these.

Get a closer look at two of the modules from Akiyuky’s YouTube channel: Planets and Fast Ball Sorting Robot using EV3.

The 3rd GBC module using antenna parts (ID 3957). Hemisphere parts with planets pattern of Star Wars Series are used as decoration. A prototype of the module had no decoration of planets. Fortunately, I happened to find the hemisphere parts at my working table which were kept for another purpose, and I could attached them. The module represents that the balls go around each planet and move to the next planet as if a spacecraft traveled around planets in a solar system.

This great ball contraption (GBC) module is capable of sorting two types of balls. The two-axis gantry robot placed at the center of the module sorts basketballs and soccer balls in a pick-and-place motion. The motion of the two-axis gantry robot is quick, and the sorting speed of the robot is greater than two balls per second. The module is controlled by Mindstorms EV3. The basketballs and soccer balls are distinguished using an EV3 color sensor embedded below the guide lane for running balls.
