If you thought solving the rubik’s cube was hard, just imagine designing and building a lego robot to do the very same task. that is exactly what mike dobson did using pieces from lego mindstorms. Cubestormer, as he has named his creation, links up with a pc and can solve a rubik’s cube puzzle in under 12 seconds. the design holds the cube using four hands, which can rotate the cube in all directions. A camera is focused on the cube to tell the computer how it should turn it.
