Rubik’s Cube-solving robots are nothing new, but friends Jay Flatland and Paul Rose managed to build one you won’t believe is real. Though the setup may look complex, it’s only comprised of several webcams, 3D-printed frames and Arduino stepper motors. The custom software takes the image input from the cameras and converts it into a ‘unrolled’ that the solver can comprehend.
