Lego Curiosity Mars rover explores barren surface of Kennedy Space Center (video)
If you want to do what NASA just did, except in Lego form, then look no further. NXT builders Doug Moran and Will Gorman put together this amazing working Curiosity rover that can happily roll around plastic terrains, searching for the answer to Bowie's questions. Four of the six wheels are powered, enabling the gear to make 360 degree turns, while a fully working arm and mast are controlled separately. Of course, nothing we can say could compare to seeing it in the flesh plastic, so head on past the break to see it in action.
Lego motorized wheelchair joins Mindstorms NXT alumni (video)
It's been a while since we've come across a Lego project that's on par with a certain Pixar hero or the Rubiks solving robots, but Simon Burfield's brick-based motorized wheelchair definitely ranks close. He's cobbled together seven Mindstorm NXT micro-computers (programmed in RobotC), 14 motors, 16 touch sensors and a Technic frame to build a chair capable of carting around 200 pounds of Lego obsessed humanity. As functional as it is, the creator aims to improve the build with wireless control via Android, a task he says should be "very straightforward" over Bluetooth. If you'd like to see the demo in all its noisy glory, check out the video after the break.
Alan Turing's breakthrough machine gets a loving Lego tribute (video)
In the world of technology, having one of your inventions rendered in Lego form is the equivalent of a musician being parodied by Weird Al -- it's a sign you've truly made it and tribute to your influence. So, we're more than a little surprised to see that it's taken this long for the Turing Machine to be lovingly built from plastic bricks. The heart of this simple logic device is a Lego Mindstorms NXT set, but the soul is in Alan Turing's genius -- a man who was before his time and unjustly persecuted for failing to properly fit into society's molds. Dutch researchers Jeroen van den Bosand and Davy Landman built the device as a tribute to Turing, who would have celebrated his 100th birthday this Saturday. If you're in Amsterdam you can see the machine yourself at Centrum Wiskunde & Informatica's Turings Erfenis exhibit. Or, you can watch the short explanatory video after the break.
Plick hitches an elastic ride on the DIY robotics train (video)
Man, we hope Gumby's collecting some royalty checks for this one. One part incredible-stretching toy, and one part DIY robotics kit, the Plick project takes the traditional hobbyist approach to brick-building your own bot and slaps a little rubber all around it. The industrial design prototype from Brazilian engineer Gabriel Paciornik combines programmable robotic parts with an elastic wired connection suitable for strapping your mad scientist creations to everyday objects. So, what can you make? The kit packs a variety of sensor-based circles that react to distance and sound, giving your mod-jobs the power of movement and light. It's safe to say this not-for-market toy veers far from LEGO Mindstorms NXT territory -- and that's exactly the point. Far out video demo and its 60s beach music soundtrack after the break.
Wall-E gets a LEGO Mindstorms NXT makeover, tears up the dance floor (video)
Alright, let's all be upfront here. When you saw this Pixar masterpiece you caught yourself thinking, "Destruction of the Earth? Not so bad... if that means I get my own Wall-E." It's ok, other more robotically-adept Quebecers had the same idea. Except they managed to mix it up with a LEGO Mindstorms NXT kit and create a waste-collecting romantic of their own -- sans the devastation of our world. The brainchild of Montreal-based creator Marc-André Bazergui, project w.5 incorporates six NXT bricks, 17 motors and over a thousand parts that let the lovelorn bot reanimate his motorized chassis back into our hearts. It's an impressive feat you can watch below, but note the video has been sped up -- you didn't expect building bricks to move that fast, did you?
Pulito, the Lego Mindstorms swiffer-bot that seeks out electricity (video)
You could certainly buy a ready-made robot to sweep your hardwood floors, but doesn't building your own out of Lego bricks sound like loads more fun? That's what PlastiBots did with the Pulito pictured above, a Lego Mindstorms NXT sweeper with a host of sensors to navigate around furniture and a standard Swiffer pad to scrub. There's no fancy NorthStar or Celestial navigation packages to keep the bot on track, so it meanders about much of the time, but there is an fancy infrared beacon on the robot's charging dock to guide the creature home. When the Pulito's running out of juice from a long, tiring session of painstakingly traversing your floors, it's programmed to automatically seek out that invisible light and receive a loving 12 volt embrace from the station's brass charging bars. See it in action after the break, and hit our source link for more. [Thanks, Dave]
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.
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.
Lego-built "self tracker" train does things at its own pace
Got an immorally excessive amount of free time, and a good helping of patience to boot? Then peep the video after the break. We fell asleep a full three times watching the 1:44 video of David Wegmuller's Lego "self tracker," but that doesn't mean we don't recommend you give it a look yourself. The machine is basically a souped-up "train," which can place its own track, Wallace & Gromit style. The sluggish bot rolls onto a freshly lain track piece, and then turns to grab the one behind and swing it around in front. We're impressed greatly by the total lack of utility and all-around foolishness / ingenuity of the project, and can't wait to see what David brews up next.
WiigoBot melds Lego with Wii bowling, knocks down all 10 pins in our hearts
If a lowly blogger could die from awesomeness, we're pretty sure we'd be keeling over right about now. The Lego Mindstorms geekz0rs over at BattleBricks have managed to reach new heights of human ingenuity, melding a Mindstorms NXT kit, some clever programming and Nintendo's Wii to create an unstoppable bowling machine capable of tossing a perfect game without breaking a sweat, growing a nasty mustache, or sporting a beer belly. While the BattleBricks folks don't provide precise instructions on how to build this yourself, they've got plenty of evidence that it does, indeed, bowl like a champ. So peep the action video after the break, and then start plotting your own NXT creation conquer some other form of automated Wii Sports point inflation -- we never could quite get the hang of tennis.[Thanks to everyone who sent this in]
