Wow..
What method did it use? Petrus? Looks like it.
Otherwise it attempted to reverse how the cube was scrambled.

This was a great post... the first time around.

Let`s let up on the damn reposts, okay? Much appreciated.

re: legion 5

I don`t think anyone ever doubted the fact that if it was autonomous, it was connected to an external processor. I dont see how that makes the program any less impressive if it is full automated and "intelligent".

Though that`s unlikely.

I wonder if someone was controlling the machine off camera.

"The LEGO Camera on its own is technically not a robotic toy; rather, it is a normal webcam (a Logitech Quickcam Web) packaged into a LEGO shell. Being a normal webcam, the LEGO Camera is, unlike most Mindstorms products, not programmable and is only usable connected to a PC or some other device that supports USB webcams.

The LEGO Camera is meant to be used with the included Vision Command software which can also interface with an RCX and thus enables creating robots with "vision". The software is capable of detecting different lightings, motion, and colors. It can also be used with any other software that uses a webcam. The webcam is capable of recording up to 30 frames per second. It also contains a microphone to record sound for videos."

NVM the LEGOS did NOT solve this cube, a home PC did!

The PC merely had an output in lego format. Now if the system was wireless it would be cool, now, it`s not.

He didn`t actually program it to solve the rubik`s cube. He programmed in a set of moves like rotate 1 rotate 2 etc. and he told the computer what to do.

Whatever. There`s this Asian kid at my school that can do that way faster than a computer. Why are we training up the computers to be so smart anyways? Ever see the Terminator movies? Think about it.

I seriously doubt that this is autonomous if the initial shuffle wasn`t predetermined.
Still, the actuation is elegantly performed.

leighharper. and the grag. With a bigger budget, they could build machines that could solve it in seconds. oh and humans might solve it in 10 seconds, but it takes them minutes to analyze it. a machine can analyze way faster.

This is the second sign of the lego apocalypse. The first was when the giant lego man came ashore. We are doomed!

I once had the booklet describing the procedure, and as far as I remember it was a set of moves, with the exception of one or two simple IF THENs.

But it`s still impressive!

Legos definitely beats Rubik`s Cube.

Although, I love Rubik`s Cubes.

For the most part, the solves are one or two moves. As you get closer to solving the cube, there are three or four moves series that solve it. They seem to take you backwards a few seconds then... BAM! You have a solved cube.

When a machine can beat the human record, which is 9.86 seconds according to the site I googled. My Dad`s personal best was... 45? 50? Less than a minute. That was in the 80`s. He can still do it in less than two minutes.

Still pretty awesome how he wrote all the algorithms into the computer and got it to do all that.

Cool, but it gets boring and repetetive, it should be a time lapse video to keep interest.
