    AI learns to solve a Rubik's Cube in 1.2 seconds

    Researchers at the University of California, Irvine have created an artificial intelligence system that can solve a Rubik's Cube in an average of 1.2 seconds in about 20 moves. That's two seconds faster than the current human world record of 3.47 seconds, while people who can finish the puzzle quickly usually do so in about 50.

  • Researchers create Rubik's cube-like touchscreen display

    While modular smartphones like Fairphone or Google's Project Ara are still works-in-progress, a group of researchers from the University of Bristol's Interaction Group have designed a slick new reconfigurable form for touchscreen displays. The Cubimorph, as BIG calls it, is a single display built out of smaller, six-sided display cubes that are daisy-chained together and can be repositioned not unlike a Rubik's cube with a little more flexibility.

  • Google's new Chrome experiment lets you remix the Rubik's Cube

    Sure, you could spend a while trying to solve the Rubik's Cube in Google's new Doodle, but that may get a little dry. Google was clearly prepared for that eventuality, though: it has just launched the Cube Lab, a Chrome experiment that lets you build your own internet-based puzzle. So long as you're good with modern web code, you can produce a unique Rubik's Cube with its own artwork, effects and even logic. The 808 Cube is all about music-making, for instance. Even if you're not a programmer, it's worth checking out the ready-made Lab examples to have some fun. We just wish we'd had this when we were kids -- it would have kept us playing with Rubik's Cubes long after the original got buried in the closet.

  • Lego Cubestormer robot solves Rubik's Cube in less time than it takes to read this headline

    Until yesterday, the world record for fastest time in solving a Rubik's Cube was 5.27 seconds, which was set in the fall of 2011 by a Lego robot named Cubestormer 2. Thanks to the machine's successor (aptly named Cubestormer 3), the time to beat is now 3.253 seconds. The robot, which is the third in a series of automatons designed solely for the purpose of solving the Rubik's Cube ASAP, is powered by an octa-core Samsung Galaxy S4; it's got four high-performance ARM Cortex-A15 cores and four lower-intensity Cortex-A7 cores running the show, each one managing its own Lego Mindstorms actuator.

  • CubeStormer II rocks a Samsung Galaxy S II, makes CubeStormer I look downright slothful (video)

    CubeStormer I was pretty cool, we guess, but that was way back in 2010. Now we're all about CubeStormer II. Built by Mike Dobson and David Gilday, the puzzle-cracking robot is capable of solving Rubik's Cubes at blazing fast speeds, shaving precious fractions of seconds off of human world records. The 'bot was constructed from four Lego Mindstorms NXT kits, with our old pal the Samsung Galaxy S II serving as the its "brain." CubeStormer will be making a public appearance at ARM TechCon 2011 in California, later this month (and really, the whole thing seems like a bit of an ad for ARM -- albeit a really awesome one). In the meantime, check out some video of it in action after the break.

  • Scientists develop algorithm to solve Rubik's cubes of any size

    A computer solving a Rubik's cube? P'shaw. Doing it in 10.69 seconds? Been there, record set. But to crack one of any size? Color us impressed. Erik Demaine of MIT claims to have done just that -- he and his team developed an algorithm that applies to cubes no matter how ambitious their dimensions. Pretty early on, he realized he needed to take a different angle than he would with a standard 3 x 3 x 3 puzzle, which other scientists have tackled by borrowing computers from Google to consider all 43 quintillion possible moves -- a strategy known simply as "brute force." As you can imagine, that's not exactly a viable solution when you're wrestling with an 11 x 11 x 11 cube. So Demaine and his fellow researchers settled on an approach that's actually a riff on one commonly used by Rubik's enthusiasts, who might attempt to move a square into its desired position while leaving the rest of the cube as unchanged as possible. That's a tedious way to go, of course, so instead the team grouped several cubies that all needed to go in the same direction, a tactic that reduced the number of moves by a factor of log n, with n representing the length of any of the cube's sides. Since moving individual cubies into an ideal spot requires a number of moves equal to n², the final algorithm is n²/log n. If we just lost you non-math majors with that formula, rest assured that the scientists expect folks won't be able to apply it directly, per se, though they do say it could help cube-solvers sharpen their strategy. Other that, all you overachievers out there, you're still on your own with that 20 x 20 x 20.

  • Robot Ruby solves Rubik's Cube in 10.69 seconds, still can't beat humans (video)

    There are a few robots smart enough to solve a Rubik's Cube in seconds flat, but a group of students at Swinburne University of Technology think theirs may be the fastest on Earth. Their bot, named Ruby, recently mastered the puzzle in just 10.69 seconds, including the time spent analyzing the cube. To achieve this feat, the device scanned the toy with a webcam before its software processed the images to crank out a solution. According to the university, Ruby's 10-second mark smashes the current world robot record of 18.2 seconds, unofficially making it the fastest cube-solving machine on the planet. But Ruby still has a long way to go before it catches Feliks Zemdegs -- a 16-year-old Australian who solved a Rubik's Cube in 6.24 seconds and continues to carry the torch for all of humanity. Twist and turn your way past the break for the full PR and a video of Ruby in action, as well as a clip of Zemdegs showing us how the pros do it.

  • HTC Desire solves dodecahedron Rubik's Cube, will blow your mind (video)

    If this image doesn't have you completely dumbfounded, scroll down and watch the video. Sufficiently awestruck? Good. Now, for a little background on exactly how someone got a pile of Legos and a smartphone to solve the devil's puzzle Megaminx. The aptly titled Megaminxer enlists the Mindstorms NXT kit to do the dirty work and an HTC Desire, running a custom Android app, as the brains of the operation. Said app uses the phone's camera to take individual images of each of the puzzle's 12 faces, then processes the information and sends a signal via Bluetooth to the NXT controller, which in turn goes to town. Unfortunately, there's no explaining how they got the Android to dance like that, but, really, why ruin the magic? [Thanks, Stuart]

  • Rubik's Cube solved in twenty moves, 35 years of CPU time

    The term "God's number" refers to the minimum number of moves that it takes to solve a puzzle like the Rubik's Cube. Because, you know, if God truly is omniscient (and not a node in a vast satellite network, à la Philip K. Dick) you can bet your bubby that it would be able to solve such a puzzle in the minimum number of moves -- and it would have nothing better to do all day than solve puzzles. According to a team of engineers and some thirty-five CPU years worth of idle computer time (supplied courtesy of Google) it has been established that of any of the cube's 43,252,003,274,489,856,000 potential positions, a solution can be found in twenty moves or less -- making God's number twenty. And we're guessing that any of those solutions has to be more satisfying than our Uncle John's own Rubik's Cube solution (which he taught us in the early 1980s), removing the stickers and putting them back on in the proper sequence.

  • Motorola Droid solves Lego-encased Rubik's Cube in 24 mind-melting seconds (video)

    Oh sure, you've seen your disgustingly hairy cousin solve a Rubik's Cube in 3 minutes and 13.4 seconds, and we've seen quite a few sophisticated robots do it in far less time. But in the latest episode of "Yes, Droid Really Does," we've got Motorola's darling solving a Lego-encased Cube in just over 24 seconds. Let's recap: a Droid, a Mindstorms NXT monstrosity, a Rubik's Cube and faux techno. Is there any chance you aren't clicking through to watch this video? Update: Whoops -- had the wrong image in there somehow. Fixed now! Update II: Drats -- the video owner removed the clip. We'll keep it embedded should it return. Update III: It's back!

  • Lego Cubestormer robot solves Rubik's Cube in sub-12 second whirlwind (video)

    Robots born with the sole purpose of solving the Rubik's Cube are nothing new, but we're pretty sure we haven't seen one crack the code in under a dozen seconds before. The Cubestormer, which is built from a myriad Lego Mindstorm kits, recently took hold of the famous block and lined up every color without breaking a sweat. Oh, and did we mention that it took less than 12 seconds? It's worth noting again, either way. Hop on past the break and mash play to have your mind blown, not to mention your own intelligence insulted.

  • Rubik's TouchCube to make debut this weekend... on QVC

    It's not every day that QVC gets first dibs on hot new gadgets (though it's occurring far more frequently than we're proud to admit), but we're hearing that the teleshopping channel will be the place to go if you want to be among the first to own a Rubik's TouchCube. Believe it or not, the swipe-controlled retro toy will be available to buy for the first time on the Christmas in July segment this weekend. Look - if you've been wondering what QVC looks like in full, unadulterated HD, but have up until now failed to secure a good excuse to check it out, this is your chance, and yes, you're welcome. The full statement from the company is after the break.

  • Rubik's TouchCube hands-on and video

    We just stopped by TechnoSource's booth at the Toy Fair to check out its just-announced Rubik's TouchCube, a fully touch-sensitive update on the old classic Rubik's Cube. The new model boasts a few features the old one did not (besides the lights and touchscreen), namely undo and hint options if you get stumped. Each of its six sides are touch-sensitive, and the cube's got an internal accelerometer so that it only recognizes the touching going on on the top side of the cube. It also remembers your place even if you turn it off -- great for those of us who will likely spend years trying to solve it just once. The Rubik's TouchCube is going to hit shelves this fall for $149.99. Check the gallery and video demo after the break %Gallery-45090%

  • Rubik's Cube gets spherical twist as Rubik's 360

    Unlike Microsoft's own Xbox 360, the Rubik's 360 is actually round. Imagine that, right? Said device is about to be officially unveiled in Germany this week at a national toy show, and while many question its ability to recreate the wonder and amazement associated with the original Cube, puzzle aficionados the world over are still enthusiastic about giving it a go. The unit features six balls trapped inside of three transparent plastic spheres; in order to solve it, players must figure out how to get the internal balls "from an inner sphere into matching slots on the outer sphere by shaking them through a middle sphere that has only two holes." Sadly, we'll have to wait until August before being perpetually frustrated by yet another Rubik's invention, but needless to say, we're pretty stoked to get irate later this year. [Thanks, Sam]

  • Amazing art done with ... Rubik's Cubes?

    If a custom Rubik's Cube depicting Mario and Luigi wasn't enough for you, then you might want to check out this. It's some of the best Rubik's Cube art we've ever seen, with tons of cubes being used together to depict a jumping Mario. The amount of time it would take to solve all of these cubes in the correct way, as well as attaching them together to create the desired image, must be a long and painstaking process. We commend such effort and wonder what kind of price an artist would put on such a project.
