My great friend, Mike Dobson and I got together to create CubeStormer II - Enjoy!

You may be interested to read about the journey that Mike and I took to arrive at CubeStormer II's record being printed in the book of Guinness World Records 2013

That's crazy! Wish I could actually see this thing in real life.

Robots 1, Humans 0....but only after extra time. Lego rules!

Simply amazing does it use a specific method or does it, you know, robot it? xD

Somebody should learn a robot to do CFOP solves, so it would be comparable to a human. (Or LBL, Petrus, Roux or any human method.)

But this is very impressive!

A roux robot? xD

Very awesome! TPS is lolwtf.

Thanks.

I developed the software algorithm originally for my LEGO Speedcuber robot. It is a two-phase, table driven algorithm that can find a solution of around 21 moves optimised specifically for the mechanics of the robot in about 50-200ms of processing time on the smartphone.

This method is not suitable for humans unless you are capable of memorizing several hundred million move sequences!

Actually, maybe I should just have said "it robots it"

By "comparable with a human" you mean mechanically comparable by forcing it to do roughly the same number of moves?

In that case, would it be allowed to exclude the "inspection time too"?

Thanks, I'm glad you like it

Wow that's so fast. How many motors did you use to spin a side? That is geared up a lot yet still it has a reasonable amount of torque.

There are two NXT motors rotating each arm and one opening and closing each grip. Mike carefully selected the gear ratio to balance speed and torque.

A Rouxbot???
Cool name! (although I personally prefer "CubeStormer" )

However, it doesn't use the Roux method...

How long did it take you to build it? And after building it, how long until the first successful solve?
