Lego Robot Solves Any Rubik's Cube In 12 Seconds

kkleiner writes "Cube Stormer is the latest creation from Mike Dobson, aka Robotics Solutions, and not only is it made entirely out of Legos, it can solve any 3x3 Rubik's cube in less than twelve seconds. Often it can finish in less than five! This thing looks bad-ass and is incredible to watch."

This Video is FAKE

Okay, it's not FAKE but it's completely and entirely dishonest. I can solve the rubik's cube in about 20 seconds over an average of 12 solves, so I have a thorough understanding of human speed-solving. Computers, on the other hand, would go for some idea solution that a human brain is not capable of producing. This is especially true since the robot in this video moves EXTREMELY slowly, about 1-2 turns per second on average. Human hands can EASILY sustain 3-5 moves per second. This computer, to solve the Rubik's cube in 2 seconds as in the first part of the video, or 4 seconds as in the second part of the video, would have to be able to solve the cube in 4-10 moves. The optimal solution for solving a rubik's cube has already been bounded at about 18 moves (look it up).

Still don't believe me? Start watching and replay the video from 30s onwards. Freeze the video when the timer starts at 0:00 and look at the cube, it is actually a single 90 degree rotation away from a fully solved state.

The 4s video beginning at 1:07 shows several rotations of the WHOLE CUBE without making any actual moves, then does 4 turns and solve it, which means that it wasn't anywhere near a scrambled state to begin with.

More evidence that it's fake? Is there any information on this other than a 2 minute video on youtube?

If you watch carefully, the "Full Solve", which states such and claims to be a "totally random cube (Honest)", takes 10.75 seconds, including inspection. The 2.01 second solve is a demonstration of the MINIMUM time required for "inspecting and making one twist" on an unsolved cube. It is the blogger, and not the video, who makes the claims of solving in 2.01 seconds, and while it technically is a solve, the inventor rightfully does not claim such. The world record human solve of 7.08 seconds is not including the untimed inspection period. I would not consider this a dishonest video, since the video does not claim anything but the 10.75s solve to be a real solve, which by the rules of the second video's competition, would actually be an 8.74s solve....
