VOTW: Nokia N95 Solves a Rubik's Cube

by - source: Tom's Hardware US

My old friend…

The Rubik's cube was the bane of my existence growing up. As a kid, I pried my dad's apart with a butter knife and reassembled it so it looked like I had solved the puzzle. While it was nothing compared to my old man's time of roughly 37 seconds, I was pretty proud of myself for cheating the classic puzzle. Then, when I was about seven years old, I left it in the driveway and it got hit by a neighbor's car. Bye-bye Rubik's Cube.

I haven't seen a solved Rubik's cube since so this video really brought back memories. Usually we'd give extra points for solving a 4x4x4 cube but given that this is a computer programmed to solve the puzzle, we don't think it matters how big the cube is.

Using an ARM processor, a lot of LEGO technic pieces and a Nokia N95, this machine scans each side of the puzzle, maps out the cube and then solves the puzzle accordingly.

Although Im a Nokia fan and have had N80, N95, N85, N96, N85 etc etc, I dont see how this is soo brilliant, Im sure anyphone that uses that app will be able to do this task

Not all that impressed. The only impressive feat here is building the lego machine, and programming software that makes it all happen. The fact that the ARM processor happening to be the unit doing all the math is meaningless in my mind.

Yes blueberry pancakes would be nice :)

It's neat, but most people don't realize that solving a rubiks cube requires nothing more than memorizing algorithms. Probably shouldn't be too difficult for a computer to do..

That's not cheating. That's lateral thinking.



ok, I did that too.javascript: void(0);

And sorry about that cryptic end to my post. Fat fingers and Chrome don't mix.

I processor solving algorithms!?!? This is news to me.

The lego technic are far more impressive than the arm processor running the robot. In college, we used zylog z80 processors for all our robotics labs... it doesn't take much to run a robot.

lol, sorry, but I think that's great. How many of you can solve the 4x4x4 cube, build a lego machine like that, or program software to run all of it?
Personally, hats off to the guy that did it.

Jeez, guys lighten up... it really doesn't matter if it was an Arm powered N95, or Deep Blue solving it... its still a cool use of innovation an technology and an entertaining video.

Wouldn't a rubix cube would be 4*4*6

four pieces high, four pieces wide and six identical sides.

I can do the programming part but building LEGOs,etc is harder.

The older Mindstorms sets were also used to solve the classic 3x3 Cube. This is a pretty slick iteration, though, and it probably doesn't even require Vaseline on the cube to run.

4 on the x-axis, 4 on the y-axis and 4 on the z-axis.

I wonder how different the response would've been had it been an Apple iPhone instead that was used? People probably would've been frothing at the mouth with hype.

It's good to see some articles showing that, y'know, there ARE other smartphones out there.

Nokia phone sales have fallen. I wonder why he wanted to make software for an ancient phone like Nokia? Nokia has lost the game, Android, Dell and iPhone rules!

You need an i7-8xx core to do that - 130W thermal dissipation will cook whatever you want.

I agree. I hope I can do that myself.
