NSF backs development of laser-guided robot wheelchairs

by Joseph L. Flatley posted Nov 10th 2009 at 3:54PM

It's been well over a year since we last saw the laser-guided, self-docking wheelchair developed by folks at Lehigh University, and now the team is back with an altogether more ambitious project. According to associate professor John Spletzer, the recipient of a five-year CAREER Award from the National Science Foundation, the goal is to "extend the autonomy of the wheelchair so it can navigate completely in an urban setting and take you wherever you need to go." This will be done by equipping robotic chairs with laser and camera sensors (which the team developed for the 2007 DARPA Grand Challenge) as well as exhaustive, Google Street View-esque maps of the city where they will be operating. Of course, these guys will be operating in a busy urban environment, so in addition to large-scale 3D maps, they must be equipped with motion planning features for operating in dense crowds and a changing environment. It's too soon yet to say when these things might become available commercially, but if you're a resident of the Good Shepherd Rehabilitation Hospital in Allentown, PA, you might have your chance to test one soon enough.

Panasonic's Robotic Bed makes sleeping with robots a reality

by Thomas Ricker posted Sep 18th 2009 at 4:42AM

Know what we hate? The long groggy walk from our beds to the computer. It's only 10 feet but its potentially dangerous and honestly, exhausting. Panasonic's Robotic Bed is set to change that by automatically transforming from a static bed to a mobile wheelchair... and back. Once converted, the robotic chair can navigate the home while avoiding obstacles with "no need for training," according to Panasonic. The canopy is fitted with a television and plugs into the home network so you can control home appliances and view security cameras. Obviously, its primary purpose is to give people with limited mobility more independence. However, bloggers can dream can't we? The Robotic Bed will be unveiled for the first time at the Tokyo Big Sight show on September 29th.

Japanese researchers debut wheelchair-replacing RODEM "universal vehicle"

by Donald Melanson posted Aug 27th 2009 at 1:07PM

Look out, Rascal. You may just have some new competition in the fast-moving field of slow-moving mobility -- at least if this new RODEM prototype developed by a group of research partners at Japan's Veda Center (including Tmsuk) actually hits the market. Apparently designed to be used as both a replacement for a wheelchair and as a general purpose "universal vehicle," the four-wheeled RODEM allows folks to simply lean forward slightly without the need for any back support, which the group says will let people get in and out of the vehicle more easily, and with less assistance from care-givers. Of course, no sci-fi inspired vehicle would be complete without a few bells and whistles, and it looks like the RODEM is more than capable in that department, with it packing some built-in GPS, automatic obstacle evasion control, automatic slope correction, an "autonomous navigation function," voice recognition, and some sort of vital monitoring system (all of which may or may not actually be included in the prototype) -- not to mention a top speed of 6 kilometers per hour.

Toyota's mind-controlled wheelchair boast fastest brainwave analysis yet, most stylish EEG cap

by Ross Miller posted Jun 30th 2009 at 3:13AM

Mind-controlled wheelchairs are becoming all the rage these days, but before you start letting your thoughts wander elsewhere, this latest from researchers at the Brain Science Institute (BSI) -- Toyta Collaboration Center have what they claim is a system that'll control the ride using brain waves analyzed every 125 milliseconds, which it boasts bests the competition by several seconds. Testers using the wheels and EEG cap system have achieved accuracy up to 95 percent which, as you can see in the video after the break, will make cubicle obstacle courses a challenge of the past. So what mindset do we have to be in to trigger the flames?

Mind-controlled wheelchair prototype is truly, insanely awesome

by Laura June posted May 4th 2009 at 2:54PM

We've seen brain-controlled wheelchairs in the past, but we've never seen them in action. This one, developed and built at the University of Zaragoza in Spain, uses an EEG cap worn on the head, using a P300 neurophysiological protocol and automated navigation. The user sees a real-time visualization of his surroundings on the screen in front of him, and then concentrates on the space which he wants to navigate to. The EEG detects the location, which is then transmitted to the autonomous navigation system, which then drives the chair to the desired location, avoiding any obstacles that might be in the way. Once the location has been chosen, the user can sit back and relax while the chair does all the work, making the use of the system far less mentally exhausting than some previous iterations which demand constant concentration on the target. Although there is no information about commercial availability of the wheelchair, it has been successfully tested by five different participants in a study. There's a video with a more detailed explanation of its impressive operation after the break.

USF scientists develop brainwave controlled wheel chair

by Joseph L. Flatley posted Feb 7th 2009 at 1:17AM

Those crazy kids at the University of South Florida are at it again -- they've given us 'intelligent' scarecrows and engaged an RFID network in the fight against Alzheimer's, and now they're doing some rather interesting work with the Brain-Computer Interface (BCI). The device uses an electrode-covered head cap to capture P-300 brainwave responses and convert them into action, such as "typing" or manipulating a robotic finger. The team has developed a motorized "smart wheelchair" that allows users to pilot the chair and even control a robotic arm without any physical movement whatsoever. USF researchers say that this will be a great help not only for those with special needs, but also for the extremely lazy.

MIT developing autonomous wheelchair that listens when you speak

by Darren Murph posted Sep 21st 2008 at 6:39AM

Oh MIT, do the wonders that come from your halls ever cease? Yet another remarkable development is emerging from the fabled institution, and this time it's an autonomous wheelchair that can remember important places in a given building (read: the hospital ward, your house, the local arcade, etc.) and then take you there on command. In other words, the voice recognizing chair could understand phrases of direction, such as "head to the kitchen," and it would take on the burden of navigating the halls while letting the rider chill. The researchers are implementing a system that can learn and adapt to the individual user, and in the future, they'd like to add in a collision-avoidance system and mechanical arms to help patients lift and move objects. Say, can regular joes / janes buy these? We're totally feeling this over the Segway.

The firebreathing wheelchair is the best worst idea on four wheels this year

by Paul Miller posted Jun 1st 2008 at 12:09PM

Now that our wheelchair-ridin' pals can rock the virtual drums, the natural next step is fire breathing electric conveyances. Built by Lance Greathouse out of golf cart parts, a Marine rescue helicopter seat and, of course, a flame thrower, the "wheelchair" can zip along at 22 miles per hour, burninating whatever might cross its path. Lance says it best: "It was made for the disabled person looking for something a little different, why drive something that looks like a medical device when you can drive something lethal?" Exactly.

Researchers show off laser-guided wheelchair that docks with vehicles

by Donald Melanson posted Apr 30th 2008 at 2:37PM

We first heard about this laser-guided wheelchair way back in 2006 but didn't really have much more than promises from the team behind it about exactly what they had in store. As New Scientist reports, however, it seems that the folks from Lehigh University and Freedom Sciences are still hard at work at it, and they're finally showing off some of their progress. The wheelchair is apparently still not entirely automated though, with it needing to be driven to the rear of the vehicle by remote control, after which the on-board LIDAR system kicks in and loads it onto the lift all by itself. Not surprisingly, the estimated price for the eventual commercial version has also gone up since we last heard from the team, with it now set to demand $30,000 (as opposed to $15,000 to $20,000) when it goes on sale later this year, assuming it gets the necessary FDA approval. Until then, you can head on over after the break to check it out in action.

Mind controlled motorized wheelchair demonstrated

by Conrad Quilty-Harper posted Sep 10th 2007 at 7:10PM

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

by Nilay Patel posted Jul 6th 2007 at 6:40PM

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.

Sweden develops MICA: the intelligent, autonomous wheelchair

by Darren Murph posted Dec 17th 2006 at 11:04PM

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. [Warning: PDF link]

ATRS to make entering / exiting vehicles easier for handicapped individuals

by Darren Murph posted Dec 13th 2006 at 7:24PM

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

by Darren Murph posted Nov 22nd 2006 at 1:27PM

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.

Suzuki Motors unveils MIO: the fuel cell-powered wheelchair

by Darren Murph posted Sep 28th 2006 at 7:39AM

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.
