Autonomous robotic fleas could create distributed sensor network
We've seen a fair bit of mesh networking approaches lately, and thanks to a unusual project going on at the University of California, Berkeley, the next great ad hoc network could be started by a horde of bugs. Sarah Bergbreiter has developed an "autonomous robotic flea has been developed that is capable of jumping nearly 30 times its height," thanks to what could possibly be hailed as the "world's smallest rubber band." Interestingly, the creator hopes that the minuscule bugs could eventually be used to "create networks of distributed sensors for detecting chemicals or for military-surveillance purposes." The Smart Dust initiative could eventually be expanded to grow wings, but for now the solar-powered bugger will stick to hoppin' via a "microcontroller to govern its behavior and a series of micro electromechanical systems (MEMS) motors on a silicon substrate."[Via BoingBoing]
Motivatrix's MX9 Workout Master replaces aging stationary bike
Dance Dance Revolution has certainly helped pave the way for the health-conscious set to exercise whilst gaming, and even the Wii has sparked an outbreak of get-fit kids who endure hours of Wii Sports just to melt off those pounds, and now Motivatrix is hoping to get its exercise / gaming machine hybrid into your fitness room in place of that not-so-thrilling elliptical. The MX9 Workout Master mimics existing DDR systems in design, but it manages to feature a number of internal games inside to keep your workout sessions fresh. Additionally, the machine not only recognizes fancy footwork, but built-in sensors can understand arm flailing as well, and you can even "jam out to your own music" while breakin' a sweat. Most interesting, however, is the fact that its also an internet-enabled machine, meaning that exercise freaks across the land can compete against one another, giving even the least motivated individuals something to work for. No timetable was noted as to when we'd see these things hitting sporting goods sections, but until we get a crack at "Calorie Killer," we'll just stick with Simmer Down Sprinter.[Via CNET]
University of Essex developing autonomous model car
DARPA's Grand Challenge certainly snags a majority of the spotlight when talking about autonomous vehicles, but researchers at the University of Essex are looking to tackle the idea on a (literally) smaller scale. Seeking to craft a "driverless model car," the project will reportedly utilize a standard remote control model vehicle, which will be flanked by a PC, camcorder, and a bevy of sensors. Supposedly, the software that will be riding on board will allow the vehicle to be "entirely autonomous" by recognizing obstacles, making tactical decisions, and driving itself around a test track. The team responsible for the prototype hopes that this small-scale, low-cost endeavor will "pave the way" for autopilot cars of the future, and considering the problems we mere humans are already having with newfangled technology, that day can't come soon enough.[Via Slashdot]
Team LUX readies Volkswagen Passat TDI for DARPA Urban Challenge
Although a fair amount of entrants into DARPA's Urban Challenge flank their vehicles with hordes of less-than-attractive sensors, we've been quick to forgive such atrociousness due to the complexities involved in cruising around sans a driver. Ibeo-led Team LUX, however, is looking to add a dash of style to this year's (now lucrative) competition, as its Volkswagen Passat TDI wagon touts a clean exterior, three "laser scanners" for complete 360-degree perception, and amazingly, not much else. Apparently, the trio of uber-capable modules are all that's needed to keep the car under control, and while we'd typically doubt such bold claims, the 11-member team has quite an impressive resume in the autonomous vehicle department. Still, the minimalist approach will probably face some stiff competition, and although we're certainly not experts on design, we still think the Wolfpack's Lotus packs a bit more sexy.[Via CNET]
Creation adds sixth sense for WiFi hotspots
We know, there are (supposedly) folks out there with the ingrained ability to sense wireless networks without any mechanical assistance whatsoever, but considering that we can't all live next door to Kate Figes, the rest of us mere mortals need a bit of manmade aid. Enter the WiFi Heartbeat, a custom built sensor / vibration device that autonomously sniffs out WiFi signals, determines the signal strength, and sends a pulsing signal to you based on just how close the hotspot is. The creator states that all you'll need is a "microcontroller, some custom interface electronics, a small vibe motor, and an off-the-shelf WiFi detector," and if you've given mildly difficult DIY endeavors a go before, we can't imagine this one causing too much strife. For those of you still on the fence, be sure to hit the read link for all the details you'd need to craft your own, and click on through for the video demonstration.[Via MAKE]
LEGO Autopilot takes to the skies autonomously
Seems like LEGO mods are gaining quite a bit of steam these days, as not only are the amount of block-based creations growing by the week, but Bosch has even unveiled a dishwasher specifically made for the hopelessly obsessed. Just in case the LEGO-based Wii concoction isn't down your alley, the self-proclaimed LEGO Autopilot could be just what the voyeuristic side of you has been yearning for. Modeled around HiTechnic's NXT Acceleration / Tilt Sensor kits, it's apparently possible to build a UAV for your personal indulgences with less than a grand in cash, and if you add on the optional webcam and Bluetooth controls, you could definitely fetch a sneak peek in faraway locales. The autopilot system reportedly "controls the rudder, which keeps the plane flying level," but manually altering the servo arm can give you a taste of manual controls if you get tired of watching. Of course, this here endeavor certainly isn't aimed at the faint of heart (or budget-minded), but be sure to hit the read link to see what you're in for if you decide to give this a go.[Via Slashdot]
University of Tokyo crafts tea-grabbing humanoid to serve you better
If you've got a domesticated service bot around to flip your channels and chase away any uninvited intruders, there's not too much else a lonely, elderly individual needs from a fellow humanoid, but researchers at the University of Tokyo are crafting more lifelike and more agile servant bots nevertheless. In an effort to create a tactical team of droids ready and willing to serve the aging population of Japan, the team is working with Kawada Industries Inc. to create friendly robots that can assist folks with around the house chores such as pouring tea and cleaning the dishes. Several models were out and about during a recent demonstration, as one wheeled bot delivered beverages to its master, and other renditions responded to human movements and the bevy of sensors installed in the floor and sofa of a room. Essentially, the team is attempting to seamlessly integrate robotic life with our world, and they're already prepared to feel a lashing from privacy advocates who will protest the embedded camera systems that the robots feed off of. Still, we'd rather have a potentially Big Brother-equipped servant to make sure our favorite dramas get recorded than no one at all.
Siemens AySystem utilizes GPS / GRPS for emergency tracking, alerting
While Siemens HQ is probably still dusting itself from last year's invasion, that's not stopping the whole show 'round those parts, as the firm is introducing a new form of emergency communication with its AySystem. By utilizing worldwide GSM / GRPS networks (and optionally, GPS), the pocketable device can be tracked, modified, and used as a channel of communication between a caregiver and patient, parent and child, boss and subordinate, or any other useful combination of individuals. Essentially, the Ay token is given to the person who needs monitored, and the other party can adjust various "thresholds" such as motion (or the lack thereof), temperature, and sound, and if that limit is surpassed (i.e. a patient stops moving), the token will sound an alarm whilst simultaneously texting / calling a user-selected individual. Moreover, it can be remotely controlled and tweaked via a web-based interface, and users can add "SnapOns" such as GPS receivers and cameras to extend its functionality even futher. Thankfully, the platform in which the device runs on is entirely Java-based, which should please those looking to code their own programs to take full advantage of what's being offered. As of now, we're not exactly sure how much this fancy panic button will end up costing, but it is slated to be made available "via mobile carriers or through pre-paid plans" in the not too distant future.[Via Gizmag]
Microscopic chain mail could embed sensors, electronics into clothing
It won't be too long before those new threads sport some kind of socially-infused assistants or help you regulate body temperature, but if researchers at the University of Illinois at Urbana-Champaign have their say, your garb could end doing a lot more than that. Following up on discoveries made over six years ago at Harvard and Cambridge, the scientists have devised microscopic chain mail made from miniscule metal links, which could ultimately be woven into "3D textiles." Aside from feeling a bit like Sir Lancealot, the chain-like structures could have electronics and sensors built right in, and the flexible fabric could also conduct electricity when not beaming secret messages or being used as one large homing device for the cops to track you down. Novel as this may sound, wearing a proverbial lighting rod isn't really our bag, so hopefully the cotton biz will continue to do its own thing for old timers' sake.
Intel seeks light sensors to halt laptop scalding
Having an overheating laptop nestled on your legs isn't exactly the most comfortable way to work, but even if your Li-ion doesn't erupt on your mid-section, other forms of damage can still ruin your day life. In an effort to quell the scalding that so often occurs on today's lap-burners, Intel has issued a patent application "which uses light to sense when a computer casing is getting too hot, and automatically throttles back the power" to cool things off. Considering that hot spots emerge in various locales on the casing, a light sensor would be used to detect changes on an internal thermochromic coating, which would then relay a signal to the processor to clock down a bit in order to keep the temperatures within reason. Of course, we fully expect a taskbar icon to disable this CPU-limiting procedure for those rocking flame retardant pants, but this should work just fine for those who prefer not to dress accordingly while computing on the go.[Via NewScientistTech]
Mainnav kicks out Bluetooth-enabled MW-705 GPS watch
GPS watches certainly aren't new 'round these parts, but a timepiece that sticks up around 1.1-inches off your arm has to set some sort of unwanted record. Hot on the heels of the company's MG-920 Bluetooth GPS receiver, Mainnav is offering up a GPS wristwatch with built-in Bluetooth and a SiRF Star III LP chip that could probably double as a weapon in a fistfight. Aside from sporting an unnaturally large design, the Taiwanese device can track your current position, operate as a standalone GPS receiver, and also handle heart-rate monitoring, speed and distance tracking, and sense the temperature whilst frolicking in the great outdoors. Unsurprisingly, this beast can handle underwater excursions without a hitch, and the built-in Li-ion cell should keep things humming along for a good bit before needing a recharge. As of now, it doesn't look like Europe nor the US will ever see the behemoth on their shelves, which seems fairly smart considering the fashion sense most of western civilization holds dear.[Via GPSGazette, thanks Dimitris]
Mini-Z T-ray imaging device takes home the gold
We're all about giving golf claps where they're due, and a healthy round is certainly in order for Mr. Brian Schulkin. The doctoral student in physics developed a breakthrough terahertz imaging device, dubbed a T-ray, that has already demonstrated its ability to "detect cracks in space shuttle foam, image tumors in breast tissue, and spot counterfeit watermarks on paper currency." The Mini-Z marks the first time such a powerful device has become portable in nature, weighing just five pounds and taking up about as much space as your average laptop. Taking home the first Lemelson-Rensselaer Student Prize ($30,000), Schulkin explained that this device didn't pose the same health risks as typical X-rays, and unlike ultrasound, terahertz waves can provide images and spectroscopic information without contacting an object. As expected, the patent-pending technology is already up for licensing, and has already received quite a bit of fanfare and commercial interest from larger companies. So while you may never personally encounter Brian's earth-shattering invention, we're fairly sure this young lad's working days are already drawing nigh if he so chooses.[Via Physorg]
Ugobe readies Pleo for pre-order, kicks out feature spot
Sure, you've probably seen way more Wowwee robot action in the past few weeks than you ever thought your retinas could stand, but since you persevered, why not give this not-exactly-related family member a few ticks of your time too? Ugobe's Pleo has been a long time coming, and while we've seen a small clip of the dino in action before, now the two-week old Camarasaurus has its very own advertising spot. The video showcases the wee creature's ability to "sense," feel emotions, walk, interact with its environment, and "learn" over time. Furthermore, it looks like the company's previous estimates of a March launch date could be on target after all, as the website now states that pre-order information will be available in four short days. So if you're even pondering picking up an intelligent pet from the Jurassic period that doesn't even need those uber-expensive booster shots, click on through for the marketing hoopla.

University's Morgui robot deemed too scary for kids
Terrifying robots most certainly aren't anything new, and be it frightening or downright creepy, there's probably a bot out there weird enough to freak just about anyone out. Enter Morgui, the University of Reading-based robot that has been around for some time, but is just now getting the credit a bizarre skull that follows humans around should. The creation, which consists of a disembodied head, oversized blue eyes, and a classically evil grin, has been officially banned from testing around anyone under the age of 18 (permission notwithstanding) by the school's ethics and research committee, leaving the "Magic Ghost" to spook only mature audiences from here on out. Mo, as it's so aptly nicknamed, sports a metal head, the ability to detect visual / auditory cues, and sensors for radar, infrared, and ultrasonic detection as well, but oddly enough, it cannot detect human emotion, so you better not count on this fellow to have sympathy on your soul when you're screeching. The purpose of the machine is to judge how "people react to robots," and when the bot just so happens to lack any form of facial covering beyond a skeletal structure, we're sure the reactions are quite noticeable.[Via CollisionDetection]
Sensor-clad shirt directs wheelchair sans use of arms, hands
If you think playing tennis (or pwning your television) with a Wiimote is revolutionary, how'd you feel about wheeling through downtown sidewalks without ever moving your fingers, hands, or arms? Doctors and researchers from Northwestern University and the University of Pisa have crafted a sensor-laden shirt "that could help seriously paralyzed individuals steer their wheelchairs." The garment is printed with "52 flexible, piezoresistive sensors made of electroactive polymers that change voltage depending on the angle at which they are stretched." By dynamically sensing the direction and intentions of the user, it can channel the signals to motorized chairs in order to perspicaciously propel severely handicapped individuals who have lost the use of their arms. The team has tested the unit on a paralyzed individual (pictured) in a virtual training maze, where the shirt "learned and adapted" to his specific notions to guide him successfully through the course. While the team envisions the shirt becoming even more useful by possibly adding shoulder sensors for other types of disabilities, they haven't ruled out its use in "other applications" -- and hey, we've got no digs with adding even more motion-sensing goodness to our games.[Via MedGadget]
Mazu Kan's "contact-free" Laser Martial Arts game
If you've got the bank credentials to back it up, you can build your own robotic fighting machine, or hop in the "squishy ball shooting" Land Walker and (slowly) mow down neighborhood pests as you please. But if you've only got $60, and don't feel like sustaining any major injuries when releasing that pent-up rage, Mazu Kan's Laser Martial Arts game has you covered. This two-person, "contact-free" slugfest contains a pair of wearable sensors that track your punches, dodges, and uppercuts to determine who loses their "10 life points" first. The built-in "sound and rumble" effects supposedly help you forget that you're not in an actual brawl, while the "two levels of combat" should put those newly-acquired cagefighting skills to the test. Red vs Blue tees not included.[Via Uber-Review]
Researchers prepping robot whiskers for extra sensory input
As if cats didn't have large enough egos as it is, now they're going to be strutting around, bragging about being the inspiration for the latest sensory input being squeezed into robots. We might point out to them that other cool animals like rats and walruses have whiskers too, but we're not certain it's going to do any good. All the same, these new robo-whiskers being developed by a research team at Northwestern University are pretty dang neat. The whiskers can sense shapes or the flow of liquid, all based on a single sensor at the base of each whisker. Even more impressively, the whiskers can accurately represent the contour of an object, just by brushing across it. There are plenty of uses for the sensors, such as feeling around in the dark, supplementing cameras and avoiding obstacles. They'll also help researches understand all that fancy whisker-based neurology taking place inside of rats, which we suppose in turn should lead to better bots, which is really the point in the first place, right?
EnOcean harvesting power from the environment, not batteries
Remember EnOcean's batteryless / wireless light switches on display last year? Don't sweat it, neither did we. Still, that hasn't stopped EnOcean from experimenting with battery-less sensors which harvest electricity from vibrations (pictured) and temperature differentials. According to EnOcean, their prototype thermal-differential sensor attached to say, a water pipe, can harvest up to 50-milliwatts as long as one surface is 3-degrees Celsius higher or lower than the immediate environment. While that pales in compaison to batteries, it's still enough power to transmit a tweaked RF signal as far as 300-meters in an open warehouse or 30-meters through walls. Nearby sensors can also act as relays to extend signal transmission. Link the sensors with a thermostat and you can create micro-climates around the home; link 'em to a home automation system and control your house without the need to run power and Cat 5 / WiFi everywhere. Now someone get those X10 spammers home automators on the horn, we smell a business op.
Nike+iPod available for pre-order
Exercise nuts looking to pick up one of the Nike+iPod Sport kits to enhance their workouts can finally place their orders on the Apple site, and can expect delivery of their purchase in four to five weeks. At $29, the kit is quite the bargain too, except that it won't do you much good without the hundreds of dollars of electronics and specialized footwear necessary to record and analyze every aspect of your morning jog. Luckily, Nike has been busy releasing several pairs of sneakers with that dugout under the sole for the wireless sensor, so even if the nano continues to remain a relatively pricey luxury, you should eventually be able to buy a pair of compatible kicks that won't break the bank.

RuBee protocol overcomes RFID shortcomings
Just when you thought you were safe from RFID-snooping technology, a new contactless transmission system comes along that promises to make your lead-lined wallet obsolete, thanks to its ability to transmit data though metal and liquid (not sure about liquid metal though). The IEEE has just tasked a working group with finalizing the specs on the so-called RuBee protocol, which uses magnetic -- as opposed to radio -- signals in order to transfer information, making it useful for so-called "harsh environments" where RFID chips fail, such as retail locations where shoplifters line their bags with aluminum foil to fool anti-theft systems. While RuBee's similar transmission range and cost would make it seem like a no-brainer replacement for current RFID applications, its relatively slow speed makes it unsuitable for tracking the numerous, moving products in a typical warehouse. RuBee-enabled devices will also have the advantage of transmitting data directly to the Internet, and with backers like Sony, HP, IBM, Best Buy, and Tesco, you can bet that we'll be hearing more about this tech in the coming year.[Via The Inquirer]
