Apple trying for patent on electromotive charging, could use that confident stride to charge iPhones
We've seen the concept of electromotive (movement-based) charging before, but it usually comes at the cost of either a clunky design or a limitation to very low-power devices like watches. Apple has been experimenting with a concept that could power gadgets as big as iPhones and iPods with that spring in your step -- and without the bulk of any extra wires. A newly published patent application uses flat, printed coils to generate electromagnetic induction through movable magnets; as the device bounces around in your pocket, the magnets slide past the coils and run them through the magnetic fields they need to build electricity. It all sounds grand, but it's hard to tell from the very recent June filing whether the technology is enough to keep devices completely powered or simply delays the inevitable. We'd still suggest getting back into shape, though, in the event that morning run can one day save you from hunting down a wall outlet.
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.
Samsung files patents for robot that mimics human walking and breathing, ratchets up the creepy factor
As much as Samsung is big on robots, it hasn't gone all-out on the idea until a just-published quartet of patent applications. The filings have a robot more directly mimicking a human walk and adjusting the scale to get the appropriate speed without the unnatural, perpetually bent gait of certain peers. To safely get from point A to point B, any path is chopped up into a series of walking motions, and the robot constantly checks against its center of gravity to stay upright as it walks uphill or down. All very clever, but we'd say Samsung is almost too fond of the uncanny valley: one patent has rotating joints coordinate to simulate the chest heaves of human breathing. We don't know if the company will ever put the patents to use; these could be just feverish dreams of one-upping Honda's ASIMO at its own game. But if it does, we could be looking at Samsung-made androids designed like humans rather than for them.
Google Maps for Android takes you inside with improved walking directions

Version 6.7 also features 360-degree photo views of businesses, to help ensure that you really don't get lost once inside. Also new is nearby deals that can be accessed by clicking "Offers," so you can nab some sweet deals within arms' reach. The latest version is up for the download now via Google Play. If you're still lost, please consult the instructional video after the break.
National Geographic TOPO! maps find their way to Magellan eXplorist GPS devices
If you're more about the mountainous views, than Mountain View, then you might be pleased to hear that Magellan is bringing National Geographic's TOPO! maps to its eXplorist range of outdoor GPS devices. More specifically the 310, 510, 610 and 710 models. If you like the sound of the full color USGS topographic maps, then they are available on a subscription basis for $30 a year. If you don't already own a Magellan device, however, then you might be more interested in one of the forthcoming TOPO! bundles, if you can find your way to a retailer that is.
Student's push to make Raleigh more walkable relies on homemade signs and QR codes
Walking is apparently underrated. So University of North Carolina at Chapel Hill student Matt Tomasulo decided to engage in some "guerilla urbanism" in January with fellow fans of bipedal activity, posting 27 signs at three Raleigh, NC intersections as part of the "Walk Raleigh" project. The cardboard and vinyl signs contained snippets about how many minutes it would take to walk to must-see destinations like Raleigh City Cemetery, as well as QR codes for downloading directions. Like the activity it promotes, Tomasulo says the idea behind the project is simple: It's OK to walk. Apparently, Tomasulo and his buddies did such a great job with the signs that it took the sharp folks at the city government a month to catch on and take the stuff down. The city has since walked back its opposition to the signs, however, and put them back up as part of a 90-day pilot project. In the meantime, Walk Raleigh has turned into a Walk [Your City] Kickstarter campaign to put your wallet where your feet are.
Daily iPhone App: Walkmeter 6.0
I'm not a big fan of running, but I love cycling and walking, so I'm always looking for nice iOS apps to compliment my activities. A beautiful app I've fond for tracking my walks is Walkmeter 6.0 by Abvio. If Abvio sounds familiar, it's because we've covered their Runmeter app in the past. Abvio actually makes three apps (Runmeter, Walkmeter, and Cyclemeter) that all do the same thing: they use the iPhone's built-in GPS to track and record your favorite exercises. Though all of the apps actually track any number of sports (walking, running, cycling, skying, etc. -- no matter which app you have) the developer decided to make three separate apps because he thought the individual names and icons would appeal to people depending on their favorite sport. That's something I think is cool, even though others might think the developer is trying to snake people in buying multiple apps when he's not. In our earlier review of Runmeter, we told you about the enhancements that came with version 5.0 of the apps, including the excellent voices feature, which reads various stats to you as you exercise, the tight social integration, and the ability to export .GPX files to share your exercise's stats and maps with others. Version 6.0, which were released last month, continue to add a myriad number of features. One of the coolest features is ANT+ support, which allows Walkmeter to talk to the Wahoo Fitness ANT+ system. This means that heart-rate monitors and speed/cadence cycling sensors are communicated with in real time, giving you instant feedback. No need to wait until your walk is done to see your results. You can also set target announcements for heart rate, speed, and pace, which are read to you by the Walkmeter voice of your choosing. Another cool feature is Zones, which allows you to see how much time, distance and calories were spent during a pace within a certain range. Version 6.0 also adds Notification Center support, laps and interval training, along with dozens of other enhancements throughout the app. Walkmeter and its brothers aren't the cheapest exercise tracking apps out there, but I believe they are the best. The interface is fluid, responsive and easy to navigate, something that matters a lot if you are interacting with the app during your exercise. I've tried a lot of GPS-enabled exercise apps, and I deleted them from my iPhone once I found Walkmeter. If your current exercise app isn't doing it for you, I urge you to give one of Abvio's apps a try. Walkmeter 6.0 is US $4.99 in the App Store. %Gallery-140327%
Boston Dynamics PETMAN portends the pending robot apocalypse
If the sight of Boston Dynamics' unstoppable Alpha Dog didn't convince you of the coming robot apocalypse, then perhaps a glimpse of its bipedal relative, PETMAN, will. Last time we saw the two-legged bot, It was walking well enough, but it lacked the humanoid visage needed to infiltrate and overthrow. In the time since, however, PETMAN has gotten a more anatomically-correct body and some arms -- giving it some push-up prowess to go with its jaunty gait. As the video below demonstrates, this robot isn't a T1000 just yet, but is seems certain PETMAN and its progeny will be running and leaping over us meatbags on the way to the top of the evolutionary food chain soon enough. So our anthropomorphic replacements are on the way, but there's no need for full-blown panic... yet.
RunKeeper gets a major upgrade
RunKeeper, the free fitness tracking app, just received a major upgrade that was announced this morning. The app has been gaining a lot of attention since mid-summer, when the company launched a Health Graph API that developers have been using to integrate RunKeeper capabilities into third-party apps and devices. That's not keeping the RunKeeper team from keeping an eye on the core mobile app, and the upgrade shows that RunKeeper is listening to the desires of the user community. So what are the changes? Auto Pause takes care of one common problem with apps that record your running, cycling and walking. When you stop running to tie a shoe, talk to a neighbor, wait for a traffic light to change, or take a picture of the snake that just crossed your path, you need to remember to pause the app's timer. If you don't, you'll find that your average speed for a run, ride or walk drops drastically. Auto Pause pauses tracking when you stop moving, then starts up the timer again when you begin running again. If you use a third-party heart rate monitor with RunKeeper, the app now has Heart Rate Zone visuals and audio cues to let you know when you're in your optimal heart rate zone. The app has had audio coaching around target paces for a while, telling you if you're ahead or behind your pace. Now you can do the same thing with your heart rate, knowing when you're in the zone, need to work yourself a bit harder, or need to slow down a bit. Finally, the RunKeeper team has included updates to their GPS algorithms that improve tracking performance and stability. Altogether, the team says that the performance of the app has improved as well.
Murata Manufacturing shows off self-balancing electric walking aid
Walking assistants of the future come in all shapes and sizes -- from exoskeletons to high-tech walkers -- and you can now also this electric walking aid from Murata Manufacturing to the list of possibilities. It's inspired by some of the standalone robots that the company has built and, much like the Segway, it's able to maintain its balance and stand upright on its own (with an extra set of wheels for some added security). Unlike traditional walkers, however, it requires virtually no effort to push, with built-in sensors able to detect how much the person's body is tilted, and how fast or slow it should move to keep up with them -- it's also apparently powerful to carry a person's luggage or groceries. As you might have suspected, however, it's still just a prototype, and the company isn't ready to say when it might become an actual product. Head on past the break for the company's recent demonstration at CEATEC.
Motorola MOTOACTV hands-on (update: video with Dean Karnazes!)
So when Motorola teased its "faster, thinner, smarter, stronger" event we were pretty sure that was a not-so-subtle reference to the 7mm-thick Droid RAZR. As it turns out, the company was also being quite literal. Instead of a Xoom 2, the outfit rounded out its New York City presser with MOTOACTV, an iPod Nano-like touchscreen device that plays music and keeps track of your various fitness vitals. While we couldn't take it more than a few feet away from the pedestal where it was on display, we did get to poke around its UI for a few minutes and put that 600MHz processor to the test. You know the drill: hands-on photos below, along with impressions and a short vid after the break.%Gallery-136870%Joseph Volpe and Zach Honig contributed to this report.
The Xsens ForceShoe watches your step, helps you walk better
The technology-laden Xsens ForceShoe might better be described as a sandal. However, if you're the type of bipedal perfectionist who wants to analyze your gait using an array of 6DoF force sensors and magnetic trackers (not to mention that cunningly-disguised wireless data transmitter), then the chances are your toenails can also stand a bit of scrutiny. In fact, although the ForceShoe is primarily designed for physio patients, we think its inventors at the University of Twente might just have stumbled upon the next-gen Nike+ accessory we've all been waiting for. Unfortunately they're not on sale, but if you're a researcher looking to measure the orientation, acceleration, angular velocity, force and torque of your feet in three dimensions, you're welcome to hop past the break for the full press release.
Paralyzed man can stand and walk again, thanks to spinal implant
Here's an amazing story to end your week on a high note: a 25-year-old paraplegic is now walking again, thanks to a groundbreaking procedure developed by neuroscientists at the University of Louisville, UCLA and Cal Tech. The Oregon man, Rob Summers, was paralyzed below the chest in 2006, after getting hit by a speeding car. This week, however, doctors announced that Summers can now stand up on his own and remain standing for up to four minutes. With the help of a special harness, he can even take steps on a treadmill and can move his lower extremities for the first time in years. It was all made possible by a spinal implant that emits small pulses of electricity, designed to replicate signals that the brain usually sends to coordinate movement. Prior to receiving the implant in 2009, Summers underwent two years of training on a treadmill, with a harness supporting his weight and researchers moving his legs. This week's breakthrough comes after 30 years of research, though scientists acknowledge that this brand of epidural stimulation still needs to be tested on a broader sample of subjects before any definitive conclusions can be drawn. Summers, meanwhile, seems understandably elated. "This procedure has completely changed my life," the former baseball player said. "To be able to pick up my foot and step down again was unbelievable, but beyond all of that my sense of well-being has changed." We can only imagine.
Paralyzed student uses robotic exoskeleton to walk at college graduation (video)
Austin Whitney hasn't been able to walk since a 2007 car crash left him paralyzed, but on Saturday the 22-year-old triumphantly strode across the stage to accept his degree from UC Berkeley. He had a little help, in the form of a specially crafted robotic exoskeleton developed by Berkeley engineering professor Homayoon Kazerooni. Kazerooni and his team designed the exoskeleton with lightness and affordability in mind, resisting the urge to load it up with expensive hardware and tethering the mechanized walker to a backpack that houses a computer and a rechargeable, eight-hour battery. As a result, the Austin walker won't enable the kind of acrobatic leaps that would make Lt. Rasczak proud, but its reduced mobility comes at a reduced cost of just $15,000. That's certainly not an impulse buy, though it's a welcomed alternative to other exoskeletons that retail for $100,000 or more. Walk past the break for a video of Whitney's momentous steps, along with a clip of Kazerooni describing his creation.
Bipedal robots learn to shuffle, evolve toward doing the twist (video)
Yes, some robots are evolving to a point where they can play instruments and swing a hammer. Hilariously, though, bipedal robots are still awful at turning in a tight radius. Several presenters at the International Conference on Robotics and Automation have been working on a solution: instead of making them take steps, program robots to shuffle. This allows turning without complex weight-shifting -- every time your foot leaves the ground, you have to adjust your balance to remain upright. Keeping your feet on the ground avoids that fairly complicated process, and can make robot-turning quicker, and possible in confined spaces; most current bipedal bots require lots of time and space to turn. See the video after the break for an example from Japan's Osaka Electro-Communication University. It may look like a metal man shuffling his feet, but it's an important step toward our robot-dominated future. [Thanks, Henry]
Cornell's Ranger robot walks 40.5 miles on a single charge, doesn't even break a sweat (video)
A few years ago, engineers at Cornell were rejoicing when their Ranger robot set an unofficial world record by walking for 5.6 miles without stopping. Since then, the 22-pound bot has only built up its endurance, to the point where it can now chug along for a full 40.5 miles without a single battery recharge, or an ounce of human assistance. The Ranger pulled off the feat last week, when it completed nearly 308 laps around the university's Barton Hall running track, over the course of more than 30 hours. Engineers say that their bot's stamina has a lot to do with its energy efficiency. The Ranger runs on about 16 watts and uses them more sparingly than most of its mechanized brethren. It also saves juice by swinging its legs more liberally than most bipedal walkers, essentially allowing its limbs to fall freely before re-stabilizing itself. The robot's next challenge, apparently, will be to incorporate automatic steering into its gait, since walking in circles can get understandably dull, after a while. Gallop past the break for the full PR and a video of the Ranger's latest achievement.
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.
Lonely Planet launches audio walking tours in London
This is a cool new feature in travel apps that I'd like to see a lot more of: Lonely Planet has released some walking audio tours as apps on the App Store. Unfortunately, all of the tours so far are just based in London, but the apps will walk you around some of London's most interesting areas, including Covent Garden and the West End, bringing along audio reviews and insight from Lonely Planet's editors and experts. The apps will work offline (for tourists traveling abroad), but they're also location aware, so you can get the audio read out to you when you're in the right place as well. I love this idea -- I am a big fan of walking tours, and I think there's a lot of potential still unexplored in terms of connecting up information with users of connected smartphones. We've seen some interesting AR applications already along these lines, but I'd like to see even more ways to use your iPhone to really explore and learn more about the world around you. Hopefully Lonely Planet will get these tours rolling elsewhere soon. Right now, the apps are US$1.99, half off the usual price, for a launch sale.
MegaReader brings true multitasking to the iPhone, lets you walk and read at the same time (video)
Galaxy S owners will already be familiar with the awesome power of overlaying text on a live view of their phone's camera feed, but now their iPhone counterparts get to join in the fun as well. MegaReader, an e-reading app that's survived the cutthroat App Store waters long enough to reach version 2.1, has just added a "Heads Up Display" feature to its list of attributes. Its function is to make your iPhone appear transparent, which is achieved by relaying camera images of what's behind the phone to its front. A real life saver, a mere gimmick, or a golden opportunity for a hilarious promo video? Why not all three?
Prototype Pleo motion capture exoskeleton up for grabs: $2,400 OBO
Still haven't nailed down the perfect Christmas gift for that special someone in your life? Shame on you. Just kidding. But on the real, if you've got $2,397.99 and a lust for robotics, there's hardly a better buy available right now than this. The concoction you're peering at above isn't apt to go on sale to the general public again anytime soon, as it's a rare prototype motion capture exoskeleton that was used by (the now-defunct) Ugobe in the creation of Pleo. Word has it that this suit was vital to the R&D efforts surrounding the first edition of the outfit's robotic dinosaur, with one Caleb Chung fitting in and hulking about as computers analyzed and recorded movements. So far as we can tell, all of the circuits and wires are still here, meaning that you actually could use this for R&D of your own provided you had the right equipment to read it. Unfortunately, it'll cost a small fortune to ship a 350 pound crate anywhere outside of the continental US, but for those of you currently living overseas... well, here's your excuse to relocate. [Thanks, Colin]
