Flying Fortress Lego blimp lords over us with a Mindstorms-based iron fist (video)
Most Lego Mindstorms constructions have never slipped the surly bonds of Earth. The Flying Fortress Lego Blimp from Tyler Westmoreland and Chris Shepard won't be similarly held down, however. Courtesy of two NXTBee wireless adapters, Tyler and Chris can fly the Mindstorms NXT-driven airship using a remote control and adjustable propellers. There's no secret tricks involved, as everything is an off-the-shelf part that anyone can find, including the 55-inch helium balloons. We have proof: Tyler has shared the source code for both the blimp and the controller, so anyone with the resources can recreate the Flying Fortress for themselves. While the thought of homemade drone blimps looming overhead is slightly disconcerting, we'll steel our resolve when it means that most any enterprising builder can take Lego airborne.

Skype-controlled Mindstorms NXT car: toys over IP?
If you build it, they will come; so the saying goes. And robotics-loving Mindstorms NXT-enthusiast Leon built it. What exactly? Well, a car. But not just any old brick-mobile, one you -- yes you -- at home can control via Skype. How does one conjure up such sorcery? By training a light sensor on a laptop screen, for receiving Skype calls, a soupçon of screen sharing, all mixed with a little web code so you can pilot remotely. The final lap is over a Bluetooth connection, plus there's a clever self-charging system originally featured on these very pages. Fancy taking it for a spin? You've got until the 18th of this month before Leon gets fed-up with the constant reverse donuts. Check the video after the break to see the truly "remote controlled" car in action, and tap the source to see how you too can take it for a spin.
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]
Mindstorms NXT battle bot shoots bricks, breaks hearts (video)
There's so much to love about Martijn Hellemans' Mindstorms NXT battle tank: it sports independent suspension, cruise control, LED headlights, laser sighting, and a high velocity brick cannon. What's more, it's controlled by a PSP-Nx remote, but you know what we really love about this Mindstorms battle bot? It gets down to the smooth jazz -- and here we thought we were smitten with NXT Wall-E. Check out a video of our new Lego love, complete with quiet storm accompaniment, after the break.
NXTBee enables long-distance wireless for Mindstorms NXT, funny little RC cars (video)
Lego Mindstorms NXT is robotic democratization, DIY designing for the everyman, but being stuck with only Bluetooth or IR wireless can put a bit of a damper on your egalitarian goals. No more. Dexter industries (who previously brought us solar-powered Mindstorms) has created the NXTBee, which uses the an Xbee radio to send data much further: 300 feet for the base $55 NXTBee, up to a mile if you opt for the $78 NXTBee-PRO. You'll probably need two of the things, though, so make sure you budget appropriately. There's definitely some lag evident in the video of a long-range RC car below, but we're not sure if that's the wireless or the machine itself. Regardless, that's surely a design challenge that won't stop you from having fun with this one.
Lego bot built to test Kno's tablet textbook, human overlords watch gleefully (video)
Just because the first few tablet textbooks have shipped doesn't mean that members of Kno's development team are resting on their laurels. Product testing on the Kno tablet continues -- and it looks like Lego is doing the heavy lifting. They've put our favorite plastic building blocks to work by constructing a Kno stress tester out of Lego Technic parts. The robot checks both the Kno's ambient light sensor and the ability of its touchscreen to accurately track the system's pen swipes and flicks. Though not as intricate as a Lego replica of a 2000+ year old mechanical computer, the robot -- with its hypnotic pendulum-like motion -- is still a sight to behold. Check the video after the break.
dSolar panels for Mindstorms bring green power to your Lego creations
When society collapses and the national energy infrastructure goes to pot, at least you'll still be able to run your fantastical Lego Mindstorms NXT creations. That's right: the fine folks at Dexter Industries are offering panels, batteries, and all the geegaws necessary to power your projects the old fashioned way: with the sun. The basic dSolar 2W System ($90) features a 9 volt solar panel with enough juice to power the NXt and a single motor in direct sunlight (about 250 mA). There is also a four watt system available for $100, as well as capacitor banks, parallel connectors for multiple panels, and more. Hit up the source link to get started -- but not before you check out the video after the break.
Lego Mindstorm NXT enlisted for shirt-folding robot
All we have to say about this shirt-folding robot is that it does a better job than we could ever hope to. And for that, we love it. Video is below.
Lego bipedal bot takes several small stairs for man, one big fall for robotkind (video)
Climbing stairs is one of the hardest physical tasks for a bipedal collection of motors and circuits, as Honda's ASIMO can relate, but one man's managed to achieve just that with this head-banging Lego Mindstorms NXT robot. After spending years tinkering with the plastic blocks, 222Doc's X-2 Chicken Walking Biped can autonomously walk up and down flights of small steps with relative ease, perform headstands and even scale five-inch cinder block cliffs if precariously pushed. The robot requires only seven Lego servo motors plus a touch sensor and gyroscope in each foot, but also uses a pair of third-party multiplexers (also spotted in that transforming Wall-E) for fine control of the extra motors. Watch it perform after the break, but stop the second video at 3:20 if pain makes you queasy -- the bot takes a pretty ugly spill.
Ask Engadget: best robot platform for under $400?
We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Ryan, who reckons it's about time he stopped playing with Lego blocks and began playing with a real man's robot platform. Just kidding about the Lego bit. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com. "I am an aspiring roboticist who has been using Lego Mindstorms NXT for a few years and I am looking for the next step up. I have a budget of about $400. I am looking for something that has more motors, more sensors, and a way to have it live feed video back to a computer. I would also like a platform that has a large amount of building that can be done on top of it, such as adding an arm or another array of sensors, or a different drive base. I'm new to the world of robotics outside of the NXT, so any tips would be appreciated as well. Thanks!" Come on over, robot lovers. Toss those gloves and goggles aside for a moment and throw this guy some advice. What platform keeps you up in the garage at night?
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! Check it after the break.
G4 Cube given wheels, automation, the will to race Woz's Segway
Not wanting the Allspark to beat them to the punch, the gang at thinkingbricks has given life to an Apple G4 Cube, complete with LEGO Mindstorms NXT-borne retractable wheels, a Bluetooth controller, automation via sensors, and a creepy red LED. That transparent base really makes the wheel deployment much more dramatic, a nice touch if we do say so ourselves. There aren't any step-by-step instructions, but there should be plenty of information at the page if you're thiking of making your own as a weekend project. Either way, be sure to check it out on video, located after the break.
3D scanner made entirely from Legos
We've seen some pretty kick-ass Lego creations over the years, and this one is no exception -- if anything, it gets bonus points for not only being a pretty sweet hack, but for enabling sweeter, more complex, hacks in the future. The 3D scanner was built by Philo Hurbain, who was looking for a way to model complex Lego parts for use in the LDraw CAD program. This bad boy -- including drive components and sensors -- is entirely made from the colorful plastic toy, except for the probe needle (an old school sewing needle, apparently). The "brain" of this thing is Mindstorms NXT. But that ain't all! Check out the device in action as it models a tiny Lego frog -- video after the break.[Via Make]
Lego safe is made from robot parts, will guard your mint condish Robocop figurines just nicely
No, your eyes don't deceive: it's a Lego safe. Apparently Lego's computer-equipped Mindstorms NXT can be used for something more practical than launching robots into space (great as that was), and believe it or not, this box is actually kind of secure. Five double digit codes protect your valuables, and the dial goes both ways, so there's a left and right entry for each number -- hence, over 305 billion possible combinations. Moving the safe will trip motion sensors and set off an alarm, and bars inside strengthen the structure, so while master diamond thieves won't be deterred, surreptitious little siblings might. Video after the break, and check the right nav through the read link to dig up building instructions. [Via Digg]
LEGO Mindstorms ready for Tuesday space launch
To celebrate the 10th anniversary of LEGO Mindstorms, a group of professors, middle-school students, and corporate nerds will be launching several Mindstorms robots into near-space. The High Altitude LEGO Extravaganza (HALE) project will set the robots aloft in an atmospheric weather balloon shortly before sunrise this morning outside of Reno, Nevada. At about 100,000 feet (30km) the balloon will burst and the robots will parachute back to terra firma collecting data and photographs along the way. One robot named Lil' Joe will attempt a world record free-fall decent before deploying its parachute on a pre-programmed schedule. Mind you, the world record is attributable to Mindstorms NXT free-fall, a title we expect is currently held by your little brother sleeping upstairs.Read -- HALE Read -- HALE launch tracking
Video: iPhone + LEGO robot = superfluous genius
It's not always a question of why -- sometimes why not will suffice. The rolling bot above relies upon the Mindstorms NXT light sensor's ability to read the contrasting colors on the iPhone display. After some simple programming and DIY tomfoolery you can drive the robot from the comforts of your WiFi-enabled web browser. Overkill? Oh hells yeah, but at least now your iPhone will serve a purpose after Monday. See how the kids at Battlebricks did it in the video after the break.
The Mindstorms NXT gramophone, or, If Edison played with LEGOs
Lying somewhere between the roboflusher and LEGO car-producing LEGO factory on the practicality scale, José Pino's Mindstorms NXT gramophone brings together all the fun and tinny sound of this antiquated music system with today's modern DIY sensibilities. Using little more than an off-the-shelf NXT kit running at 25% power, and, um, a fast food beverage cup, Pino was able rig together a very basic platform for spinning his vinyl, although scratching is probably not recommended on this rather delicate setup. Keep reading for a quick video walkthrough accompanied by those old-timey tunes so popular among today's seniors.[Via Hacked Gadgets]
LEGO Johnny Five is (kinda) alive; needs input
While we're no strangers to the crazy robots people build out of LEGOs, Daniele Benedettelli's LEGO Johnny Five has got to be the most awe-inspiring brickwork we've seen in a while. The NXT-based 'bot actually contains two NXT units that communicate via Bluetooth to provide Mr. Five a full range of motion from his 6 motors and as much input as he can handle from up to 8 sensors. Benedettelli built the model after careful study of Johnny Five photos to determine his precise measurements, and two previous attempts. While we applaud all this effort, we can't imagine how much time it's going to take him to plate version 4 in gold. Check the read link for plans and videos of Johnny in action.[Via MAKE: blog]
Killer Lego sumo bots are back for more
Round 3 of the 2007 DivX Lego Sumo Robotic Championship is just as much a DivX sellout as ever, and the required browser plugin still isn't winning any friends, but despite those caveats, we're still glued to our screens for these exciting Lego bot deathmatches. With new bots like "Blue Wedgie" and "Joker" making quick work of their competition -- thanks to Blue Wedgie's clever wedge action and Joker's active sensing technique -- the matches were a bit more expedient this time around, but still quite entertaining. Nerd sport of the future? We think so.
