Mind controlled motorized wheelchair demonstrated
You know that the future's here when technology arrives that allows vehicles to be controlled with nothing but a thought. Ambient, in partnership with the Rehabilitation Institute of Chicago, has developed a wheelchair that can be instructed to move when the driver thinks about certain words. The key component is a larynx control system called the Audeo, developed by the founders of Ambient, Michael Callahan and Thomas Coleman. The New Scientist has a video demonstration of the unit, which is surprisingly eerie without the usual subtle twitch of a hand that accompanies regular motorized wheelchairs. The next stage in the project -- externally recognizing individual words imagined in the brain -- is apparently a while off: still, we think a thought controlled anything at this stage in the game is a major feat.
Self-balancing wheelchair wins Autodesk Inventor Student Design Contest
A group of Polish technical students won this year's Autodesk Inventor Student Design Contest with their design for a tricked-out self-balancing wheelchair. Functionality details are pretty light -- the site just says the chair uses "a gyroscope [to] remain vertical while only using two wheels" -- but there's no shortage of sweet gangsta lean or fly rims in the render. Screw the Autodesk competition -- these kids should've sent this design directly to Bad Boy.[Via MedGadget]
Sweden develops MICA: the intelligent, autonomous wheelchair
There's not much like getting off the couch and moving around a bit (well, not always), and a Swedish dissertation has uncovered an intelligent wheelchair that sports remote-controlled or autonomous operation. Sven Rönnbäck of Luleå University of Technology in Sweden has developed the Mobile Internet Connected Assistant (MICA), which offers up a presumably comfortable looking set of wheels to those who lack the ability to move on their own. Similar to the technology found in the Good Bytes Cafe, this wheelchair utilizes the built-in "distance-metering sensor to discover the surfaces that are available," and the technology can also be used to "ensure that the wheelchair is being used in a safe manner." The target market is "severely handicapped individuals who would otherwise find it difficult to steer a wheelchair," as these folks could take full advantage of the head-controlled interface in order to instruct the machine where to go next. Best of all, the device can learn and store maps of one's home, giving blind and visually impaired individuals the chance to cart around their crib without worrying over foreign objects foiling their plans. While we haven't heard of any VCs grabbing hold of this marvel just yet, we're sure that opportunity isn't too far away, and we're all about finding new ways to blaze a path.

ATRS to make entering / exiting vehicles easier for handicapped individuals
While there's certainly smart enough wheelchairs to get you around town without mauling a lamppost or taking out a crowd of bystanders, a Pennsylvania-based team has developed a system to get wheelchair-bound individuals in and out of their cars a lot easier. Engineers at Lehigh and Carnegie Mellon have partnered with robotic startup Freedom Sciences LLC and Freedom Lift Corporation to unveil the Automatic Transport and Retrieval System, which will supposedly "enable wheelchair users to drive while sitting in standard automobile seats that meet federal safety regulations." Currently, motorists are forced to use cumbersome, bolt-in attachments that typically require heavy modifications to the car in order to operate; the ATRS system, however, uses remote controls, wireless technologies, and "lasers" to assist drivers into a standard seat, roll their wheelchair "autonomously" to the loading dock, and close up the rear door, all while parked in the driver's seat. Sensational as it may sound, the system doesn't come cheap (nor with a wheelchair), and will cost handicapped individuals (or insurance companies) between "$15,000 and $20,000" when it goes on sale next spring.
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]
Suzuki Motors unveils MIO: the fuel cell-powered wheelchair
If you're trying to get away from that gas guzzling wheelchair, but feel a bit awkward rolling in the less-than-glamorous solar-powered edition, Suzuki Motors has got your back. Taking a leap forward from its previous lead-acid battery-powered electric wheelchair, the MIO is a motor-driven cart that gets its juice from an ultra-green fuel cell. The cell works in conjunction with a "large capacity Li-ion secondary battery," and while we aren't certain of how quickly this bad boy can streak down the quarter mile, it can supposedly cruise for 25 miles on a single fill up (four liters) of methanol solution. Aside from the power source, the MIO sports armrests that serve double duty as safety barriers, ergonomic handlebars, a comfortable mesh seating surface, and even an LCD panel that shows such useful data as fuel level and power status. While Suzuki insists the unit is simply a prototype, and refuses to hand out pricing details while it "judges consumer interest," the MIO should still be a bit easier to acquire than the sold out Tesla should it ever hit stores.[Via Far East Gizmos]
Intelligent wheelchair helps you avoid hazards
Late last month, we regaled you with a story about Toyota's advanced collision detection technology that uses sensory data to trigger an automatic slowdown in cars. Clearly, one of the research teams at Japan's National Institute of Advanced Industrial Science and Technology is paying attention to what their countrymen in Toyota are doing -- for they've just come up with a similar system in wheelchairs. Recently developed with the collaboration of the National Rehabilitation Center for Persons with Disabilities in Japan, the new "intelligent wheelchair" has a set of cameras pointed in all directions mounted above the head of the rider to provide a complete 360-degree field of view. If the cameras detect potential hazards nearby, the wheelchair will slow down or come to a complete stop. Beyond that, the new 'chair also is decked out with WiFi, eventually being able to transmit the amalgam of video feeds to a cell phone, while also providing a means of remote control. In addition, the wheelchair will look for signs of unusual posture (we're not sure how this message is conveyed in a polite, Japanese way) and will also feature a way for the rider to direct movement of the chair simply by gesturing -- you know, so you can get your moment of glory by striking your best Washington crossing the Delaware River pose. Be sure and catch a bigger pic of the camera orb on the flip side...[Via Slashgear]
Solar-powered wheelchair (not as bad as you think)
Australian Bob Triming wasn't satisfied with the power output of his electric wheelchair, so he did what anyone (with mad DIY skillz) would do, and rigged up an elaborate solar-power system to it -- stickin' it to the man while squeezing out an extra 30 minutes of power on sunny days. The rig consists of a pair of 20-watt solar panels that deliver the 24 volts required by the wheelchair, which, when not in use, can be detached or double as a handy umbrella. Of course no DIY project would be complete without LEDs, which Bob's got covered by tricking out the side and rear of the chair with a couple non-power-hungry lights to improve visibility. Thankfully it appears that the enhanced ride will still function just fine as a regular electric wheelchair, so you don't have to be worried about Bob getting stranded when the sun refuses to cooperate.[Via The Raw Feed]
Standing Wheelchair offers heightened opportunity for paralyzed individuals
While this new adaptation of a wheelchair may resemble a certain human transporter device, the humbly-named Standing Wheelchair just might be regarded with a tad more sincerity than the dear 'ole Segway. This two-wheeled cruiser was designed to give those who have lost some of their motor functions -- paraplegics in particular -- a new way to experience the world. Pending the device actually getting built, the engineering would seem quite impressive, ditching the unfashionable style often times associated with wheeled contraptions for the handicapped, and instead blending functionality with (fairly) unobtrusive lines that shouldn't draw the wrong kind of attention at first glance. Currently, those unable to walk unassisted have to resort to less-than-ideal methods to get around, and even when carted in a traditional wheelchair, they're forced to view the world a few rungs lower than the average joe (unless, of course, they're using the iBOT). Apparently this device solves that dilemma, and offers those with paralyzed lower limbs a new way to make use of their legs. While little detail is given on how the wheels are actually controlled, we can (hopefully) assume that sufficient safeguards were built-in to prevent certain catastrophes from occurring (i.e. peeling out from under you) -- while ideas to mobilize the disabled are often glossed over (or just not taken seriously), it's quite possible this Standing Wheelchair concept could raise a few eyebrows.[Via Mobile Mag]
New legs, Japan, new legs!
There are already a number of bipedal or bipedal-like bots, exoskeletons, suits, assists, and devices, but Atsuo Takanishi's team at Waseda University, in conjunction with Japanese robot superpower tmsuk, unveiled their new WL-16RIII walkbot. We know they'd be a huge boon to the handicapped, elderly, lazy, and anime-obsessed the world over, but seriously, could you imagine actually walking into a grocery store or a job interview with this thing? We can, and if they cruised into the Engadget offices we'd just be all, "You're hired."
Superfourin wheelchair opens up a new world to the disabled
A radical new GPS-enabled wheelchair with fat tires and four-wheel drive may soon offer disabled individuals the ability to tool around almost any terrain while still being protected by a virtual "tether" to a remote command center. The Superfourin chair, as it's known, is basically a modified ATV with a hybrid engine, on-board computer, and embedded sensors to monitor both vital signs and vehicle status, and was developed by Germany's Fraunhofer Institute for Information and Data Processing IITB in conjunction with Otto Bock HealthCare GmbH. Designed mostly for deployment in fleets for group outings into Mother Nature's thoughtlessly unpaved terrain, the Superfourin was also given high marks for solo use from its multiple sclerosis-afflicted test driver, who was able to enjoy the Thüringer Forest alone with his family for the first time in years.[Via Gizmag]
