The secret to solving any Rubic's Cube is to simply learn the rotation sequences to move one face to another location (google it). My son memorized these when he was 10 and he can solve any 3x3 cube in less than a minute. The robot is just faster at deciding what to move and then moving it (as it should be).

The official Rubik's site gives an interesting history of the cube. Hungarian Erno Rubik invented Rubik's cube in 1974 to help explain three-dimensional geometry.

In 1981 a 12 year old British schoolboy, Phillip Bossert, produced "You Can Beat the Cube". It sold 1.5 million copies.

Humnan's are still faster then robots with times under 10 seconds at official competitions.

Yes but the maddening part is to learn the correct rotation sequence that will move one face to another location, and do it by observation, not from the book.

That observation is devilishly difficult to detect because of the millions of possible states of the cube. That is why, once identified, the schhoolboys book sold so many copies: easier to read the instructions than do the research yourself.
