I suppose this shows the purpose of the robot: to demonstrate the electronics. There is nothing interesting about solving a cube (although this robot is incapable of rotating the center), and a 3x3 cube can be solved quite quickly by humans already (3.13s!). I'd love to see them try to do this with any other cube. There's something quite special about the 3x3 that makes it easier to solve. No parity problems like an even cube, and no center pieces to move like a >3 cube.
