Art Rendered using Rubik’s Cubes: ARRC 256

Author(s): Vasile Dan, Gabriel Harja, Ioan Nașcu

Abstract: Mosaics are decorative images and patterns that can be created using small pieces of colored stone, ceramic, glass, or other materials. Creating a mosaic requires patience and time. This paper describes a robot that creates a mosaic using 256 Rubik’s cubes. The overall process is controlled by a laptop and three Arduino Due boards. Image dithering algorithm is used to reduce the color palette, to the 6 colors of the Rubik’s cube. A custom user interface is used to manually create an image or to upload an existing image. The solutions, for one face of every cube, are generated by a genetic algorithm and a permutation-based algorithm.

Keywords: Rubik’s cube, dithering, mosaic, genetic algorithm
