Robotic legs simulate our neural system, lurch along in the most human-like way so far
We've seen some pretty wonky bipedal robots before, but scientists at the University of Arizona have gone straight to the source -- us -- to make one with a more human-like saunter. It turns out it's not just our skull-borne computer that controls gait: a simple neural network in the lumber area of our spine, called the central pattern generator (CPG), also fires to provide the necessary rhythm. By creating a basic digital version of that and connecting some feedback sensors in the legs, a more natural human stride (without balance) was created -- and on top of that it didn't require the tricky processing used in other striding bots. Apparently this throws light on why babies can make that cute walking motion even before they toddle in earnest, since the necessary CPG system comes pre-installed from birth. That means the study could lead to new ways of stimulating that region to help those with spinal cord injuries re-learn to walk, and produce better, less complex walking robots to boot. Judging by the video, it's a good start, but there's still a ways to go before they can mimic us exactly -- you can watch it after the break.
BlueBiped robot needs no power to walk for miles, as long as it's downhill (video)
The robots; they're walking -- and this one's doing it under its own steam. This passive robotic frame requires no energy input, and is instead powered by its own weight and a gentle slope. The BlueBiped can be adjusted to match the proportions of any user, and researchers plan to use it to assist people who find it difficult to walk and transport unwieldy sports equipment. It already holds the Guinness world record for the longest distance walked by a bi-pedal robot, plodding 15 kilometers (9.32 miles) in a single 13-hour stroll. Those fearing the impending Robopocalypse can at least breathe a sigh of relief that -- like some other homocidal robots -- stairs still remain out of bounds.
HECTOR insect-inspired hexapod walking robot is a smooth operator (video)
We've seen some rather nightmare-inducing robots inspired by insects, but, once again, the folks at Germany's Bielefeld University have managed to turn something inherently creepy into a rather lighthearted affair. HECTOR, or hexapod cognitive autonomously operating robot, was designed to help its creators understand how exactly real animals manage to move so gracefully. Physically speaking, HECTOR sports six legs, with 18 joints in total, that protrude from an exoskeleton made of carbon fiber reinforced plastic. Its legs are given a rather life-like range of motion provided by a special set of "elastic joint drives" and a series of "biologically inspired" algorithms, and its exoskeleton can carry a load weighing 30 kilograms -- the robot itself weighs a mere 12 kilograms. What's more, HECTOR's built to learn from its experiences. Okay, so a three foot robotic insect that can carry nearly three times its weight does sound kind of creepy in retrospect, but HECTOR really does have some smooth moves. You can see at least one of its legs in action after the break.
Iran's got a walking humanoid robot, too (update: video!)
Two years ago, Iranian students built Sorena, a white humanoid machine that reportedly wheeled about via remote control. For 2010, robots experts at Tehran University decided to update the creature -- and apparently, channel a little bit of Asimo. Surena 2 was unveiled by Iranian president Mahmoud Ahmadinejad this week, its purpose unknown. Named after a famous Persian warrior, the robot stands 4.7 feet tall, and can walk about slowly carrying its own weight of 99 pounds. Gulf News reports the robot will get vision and speech modules later on down the road. If it ends up conducting orchestras or performing show tunes, we'll be sure to keep you informed.
The iPad walks!
Sure, you've probably seen plenty of iPad mods by now but, trust us, you haven't really seen anything until you've seen an iPad walk. Details on that amazing feat are otherwise a bit light at the moment, but the man behind the mod is Kazu Terasaki who -- you guessed it -- also managed to make an iPhone walk. Head on past the break for the must-see video.
High school senior builds walking robot, the VSR-2: Talos FG (video)
These days, you don't have to be a whiz kid to build robots in your basement: off-the-shelf microcontrollers, Arduino boards and Lego Mindstorms can take care of the hard work. Adam Halverson, however, is the real deal -- he built his first robot at the age of twelve, and after six years of failed attempts, he's crafted a full-size humanoid that can walk. Filed with pistons, servos and an assimilated laptop, the VSR-2:Talos FG cost the South Dakota high school senior $10,000 to build with fellow student Anthony Winterton; he claims he could reconstruct it for half now that he's done. The hulking metal machine won him an all-expenses-paid trip to the 2010 Intel International Science and Engineering Fair in San Jose, where he's competing for up to $75,000 in prize money. We'll be watching to see if he recoups his investment -- awards will be announced this afternoon. See how the Talos FG's gears mesh in our gallery, or watch the bot take its first steps after the break. Update: The awards are in, and though Talos FG's grippers didn't manage to pull down that $75,000 grand prize, they did manage to net Halverson $5,500 in cash and savings bonds from Intel, the Cade Museum Foundation and the U.S. Army. %Gallery-93014%
ATOM-7xp humanoid robot is indeed Atom-powered, Windows-based
Our enthusiasm for this particular walking robot is unfortunately a bit dampened by a lack of video, or any evidence of actual walking, but both of those are promised to be forthcoming, and the bot still has enough going for it to distinguish itself in the meantime. Proudly made in the USA by Futurebots, this so-called ATOM-7x robot is actually powered by not one but two Atom processors (a dual-core Atom 330 and an Atom 230), which themselves power two separate systems running Windows XP and Windows 7. Those, paired with slew of sensors, gyros and accelerometers, promises to give the bot a whole range of humanoid capabilities, including an advanced stereo vision system that its creators say will let it "take on real world problems." Complete details are otherwise still a bit light, but the bot can apparently operate autonomously in addition to being used as a telepresence robot, and it unsurprisingly wasn't cheap or easy to build ("2 mortgages and lots of sweat"). We'll be sure to keep an eye out for any sightings of this one in action.
Nippon Institute of Technology unveils educational humanoid robot
We really can't get enough of these humanoid robots. Researchers collaborating from the Nippon Institute of Technology, Harada Vehicle Design, ZMP and ZNUG Design have just taken the wraps off another addition to the crew. The newest version of the e-NUVO walk bot stands about 4 feet tall, making it roughly the size of an elementary school aged child, and will be incorporated into classes to teach children about humanoid robots in a hands-on environment. We'll admit that after seeing a video of the bot in action (it's after the break), we're pretty jealous of those school children.
Walky robot understands iPhone gestures, football fanaticism (video)
Hey there sailor, we imagine you've been doing your fair share of button mashing what with a certain new bit of software out and about, but how would you like a whole new control paradigm? Taking up Steve Jobs' war on buttons, a group of grad students at Japan's Keio University have put together a comprehensive robot control interface that relies solely on finger swipes, taps, and presses. By employing the iPhone's built-in accelerometer and multitouch screen, the robot can replicate a humanistic walking motion, perform sidesteps and, when called upon, kick a football with gusto and presumed passion. Your destination is just past the break, where the video demo awaits. [Via HDBlog.it]
DIY 'Giger' robot walks after 100 hours of human work
Alright, so this so-called "Giger" do-it-yourself robot may not truly be Giger-esque, but it did cost upwards of $10,000 and take more than 100 hours to build, which is enough for us to forgive a little mis-naming. The biggest expense (and time sink), it seems, came as a result of the builder's decision to use professional-grade servos instead of the usual DIY fare, which are both finicky and pricey (between $200 and $300 apiece). After a bit of fine-tuning, however, our pal "Tyberius" was able to get the bot to show off a few moves for the camera, and even walk across the desk without toppling over (he's apparently looking to give it a more natural gait next). Head on past the break to see for yourself.
Flame is the world's most advanced -- and Dutch -- walking robot
Walking robots never cease to amaze, but "Flame" from TU Delft PhD student Daan Hobbelen is what we like to call a mega breakthrough. By mimicking the way that humans actually fall forward when walking, this robot comes insanely close to the real thing. Usually, walking robots are energy-hungry propositions, but this is the first that's both efficient and stable. Inside Flame are seven motors and a balance "organ" loaded with stability algorithms. By measuring each step, the robot adjusts stance width, speed, and gait on the go. In the end, kids, we're looking at the world's most advanced and efficient walking robot.

Cornell Ranger sets unofficial distance walking record for a robot
Think you could keep pace with Cornell's Ranger robot? Just last week, the robot walker set an unofficial world record by trotting nonstop for 45 laps (that's 5.6 miles, for those counting) around the university's Barton Hall running track. After reaching that mark, the creature presumably fell over from battery exhaustion, but the team of creators are investigating to find out the exact reason it finally collapsed. Although Guinness officials weren't involved due to too much "rigmarole," the team has quite a bit to be proud of -- after all, an earlier version of the creature only made it 0.62 miles before calling it a day. Aside from garnering bragging rights, the crew is hoping to use Ranger to better understand the "mechanics of walking," which could be used to improve rehabilitation procedures or even athletic performance.[Via Physorg]
DIY'er creates homegrown mini mech
We've seen mechs of all shapes and sizes, but typically, they either aren't for sale or are priced right out of most budgets. Thankfully, Andres Bella has created a "mini mech" that can be replicated by anyone with a few extra dollars, a decent understanding of robotics and a bunch of unused vacation time. The creature was built using a Basic Stam II microcontroller, a couple of high gear motors / pneumatic cylinders, a power supply, pressure gauge and a bunch of metal (among other things). We won't pretend to know exactly how he went about constructing this thing, but we'd certainly love to have one to take the load off our own feet (and part the seas of holiday shoppers).[Via Hacked Gadgets]
Waseda's two-legged, stair-climbing robot in action
A good 90% of our day is spent sitting in a chair delivering you non-stop gadget action, but that other 10% of our waking hours when we're forced to pursue nourishment, let the dog out, and make trips to the bathroom can be a real drag. What we wouldn't give for a chair like the lucky kids at Waseda University have built, a two-foot tall, bipedal "robot" that uses a combination of hydraulics and algorithms to saunter along fairly gracefully and even negotiate difficult terrain like the potentially-deadly household staircase. The WL-16IV, as this model is known (Waseda-Leg Number 16 Refinement Four, apparently) follows several earlier units by the same name, as well as an antiquated prototype from 2001 known called the WL-16. Hit the Read link for some good machine translation fun, or do yourself a favor and just head straight to the video of this dream chair in action.
