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.
Transformable Wall-E gets recreated with some love, Lego and DIY skills (video)
Sure, you'll have seen Lego-based Wall-E imitators before, but few recreate both the cuteness and the basic functionality of the drone quite like this one here. Programmed using Lego Mindstorms, this adorable little creation can transform itself into a box (like the real Wall-E!), pick up and carry objects, look up and down, and even produce and respond to sounds. It can be controlled remotely or left to do things by itself. Follow the break to see it on video.
Hey, Lego my Droid, you remote-controlled fiend! (video)
That original Motorola Droid looking long in tooth? Not sure what to do with it once you upgrade to Incredible, X, or even the progenitor's most direct descendant? Take a cue from Mike Partain, who threw in a Lego NXT Robot kit and some ingenuity to create a rather clever proof of concept. The building blocks serve as the bulk of the structure and motor skills, the phone serves as camera, GPS, and compass. The missing links between these two elements and Partain's remote controlling are three little pieces of complex software... so maybe it's not in your immediate future, but having a few dreams and vicariously living through the videos after the break should get you through the weekend, right? And if you really want to fiddle with one yourself, the source code has been provided.
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.
Video: WiiNxtBalance tools around, doesn't fall down
This little bot-- the NXTway-GS -- is a self-balancer, and he's pretty cute, to boot. Thanks to some clever modifications, he's now controllable via Wiimote. Using the LEGO NXT system, and some custom firmware, the little dude is connected to a computer via Bluetooth. The video of the robot in action is after the break -- but if you want to see full instructions for making one of your very own -- hit the read link. And may we suggest you slap a powdered colonial wig on yours? [Via Hack A Day]
Gaze-controlled robot gets demoed on video
It's hardly a new concept, but we're not about to bemoan the appearance of another sight-controlled robot, especially one that seems to be as simple and effective as this one created by a team of researchers from the Technical University of Denmark and the IT University of Copenhagen. That simplicity begins with the LEGO NXT-G kit that the bot is based around, which gets paired with a webcam and a laptop that's connected to the bot via Bluetooth, and to a desktop PC via WiFi. The PC comes into the picture with an eye-tracking system that lets folks control the robot as they watch the live feed from its webcam which, as you can see in the video after the break, appears to work remarkably well. The researchers apparently aren't content with things just yet, however, and they're already looking to use the system to control a wheelchair, and add some head-tracking to the mix for good mesure.
Build your own WiigoBot, the Lego NXT Mindstorms Wii Bowling Robot
Other than causing excessive pain to people walking around carelessly with bare feet, there's a lot of things you can do with Lego bricks. We recently saw that it's possible to make a fully automated Wii Sports bowling machine using Lego NXT Mindstorms, and now the complete guide has been posted over at BattleBricks. The fun has to be in the construction here, because unlike previous efforts, about all you can expect to gain from completion is a machine that can repeatedly throw a virtual bowling ball. You'll need a fair amount of kit here too, so be prepared to scrounge around that box of bricks to find those eight "Technic Pins with Friction and Slots" which you swear you saw at the bottom the other day. In the end, we're left wondering how abstract all this can get: will someone end up building a real life bot that automatically flies virtual, long haul flights? If so, how enthralling.
