MultiCuber 999 – By David

Check out the awesome MultiCuber 999, which currently holds the Guinness World Record for the Largest Rubik’s Cube Solved by a Robot. It solves a 9x9x9 cube in about 35 minutes! It uses a smartphone with a custom Android app to detect the colors of the cube and calculate a solution for the puzzle. The phone then communicates with the EV3 bricks via Bluetooth to control the motors that move the cube. The app is programmed using Java, C++ and the EV3 Programmer software.

Cool Stuff!
