Design and Implementation of a Robotic Rubik's Cube Solver Using FPGA

Abstract

Historically, solving the Rubik's Cube has been a challenging puzzle for both enthusiasts and researchers. An innovative electronic Rubik’s Cube solver has been developed, incorporating advanced algorithms and robotic arms that rotate the cube to expose each face for scanning by a camera. The scanned data is processed by a Rubik’s Cube-solving algorithm running on a Nios II processor. This algorithm determines the necessary moves to solve the cube, and these instructions are sent to the FPGA. The FPGA generates PWM signals that control servo motors, which in turn rotate the cube to achieve the solution. This system demonstrates a comprehensive approach to solving the Rubik’s Cube, integrating mechanical, computational, and electronic components to achieve an efficient and effective solution.
