An FPGA-Based Robotic Rubik's Cube Solver

We tasked ourselves with designing a mechanical Rubik’s cube solver. The mechanical arms rotate the cube to show each cube face of the cube to the camera. After each face is scanned, the cube faces are passed into the Rubik’s cube solving algorithm. The algorithm computes the moves that will be needed to solve the cube using a Nios II processor. The instructions are then fed to the FPGA, which in turn sends PWM signals to the servos to rotate the cube accordingly in order to solve the cube.”
