    very cool, I’m curious though why it needs to look at all 6 sides to come up with a solution, I should think 3 or 4 sides should be sufficient to decide which solution to run on the cube, I know it wouldn’t save much time, but just something that could possibly speed it up. I love when it turns the cube over lol, great robot, with a dash of personality.

    Why only 3 or 4 sides? The first thing a programmer wants is to have a complete model of the problem that his program must try to solve. For that, you have to have the robot look at all squares on all sides. I can’t think of a way to correctly guess any of the squares on a Rubik’s cube. Save for the very last one, ofcourse.
