Engadget Daily: Autonomous race cars, bionic arms and more!
It turns out that riding in a car going 150 MPH without a driver is pretty fun! Join us as we take a ride in Audi's autonomous concept car. Also, take a look at a DARPA project that allows amputees to control bionic arms with their mind. Check out the gallery below for all this and more in today's daily roundup.
FDA approves a life-like prosthetic arm from the man who invented the Segway
After years of testing, the FDA today approved a new type of prosthetic arm that its makers claim will bring a whole new level of control to amputees. Known as the "Luke" arm or DEKA Arm System, Segway inventor Dean Kamen has been involved in its development and unlike existing prosthetics, it can understand multiple commands at once, giving its wearers "near-natural" control of the limb. As demonstrated in the videos embedded after the break, tests show wearers can get back to easily performing tasks like using keys and locks, brushing their hair, removing papers from an envelope, or picking up an egg without breaking it. While we've seen demos using other mind control techniques, the one approved for sale does its magic with electromyogram (EMG) sensors activated by the wearer contracting muscles close to where the prosthesis is attached or on their feet, which an embedded computer translates into movement.
BBC shows us what it's like to live with a bionic hand
We've posted a fair share on bionic limbs and their advancements over the years, but rarely have we had the chance to see a video of one in real world use, on a real person. The BBC has shared a video of a man named Patrick using his bionic arm, which -- long story short -- was partially the result of being electrocuted at work. This is his second one to date and specifically, it's a prototype Otto Bock mind-controlled prosthetic arm equipped with six nerve sensors that let him use the hand as if it were his own -- it supports pinching and gripping with the fingers as well as lateral and circular movement of the wrist. Although the footage is a mundane roll of various day to day tasks -- gripping a bottle to pour a glass of water for instance -- it's quite amazing to realize technology is helping him do things he'd otherwise be deprived of. We'd suggest checking it out at the BBC by clicking the source link below.
Dean Kamen unveils revamped bionic arm and water machine, LED light bulb powered by Cree
Segway inventor Dean Kamen just stole the show at TEDMED 2010, with both a far-reaching lecture on how technology can save the developing world, and a peek at his latest projects. We'll spare you the wave of guilt for now and get right to the cool stuff, like the latest rendition of his Luke prosthetic arm and Slingshot water machine. Dean admitted he's having difficulty finding companies interested in manufacturing the former, but it's looking snazzier than when it last grabbed Stephen Colbert, with components like this shoulder piece printed out of titanium in a custom 3D printer, and it's slated to look like this. The Slingshot's seeing even more action, as Dean and company have pulled it out of the ugly box into these svelte tubes, and finally has a distribution deal (with Coca-Cola, of all companies) to bring the clean-water-from-any-source machines to developing countries in trials early next year. Last but not least, the man's got a product you might be able to afford for your home. In the quest for an item for his FIRST young engineers to sell -- a la Girl Scout cookies -- he tapped LED manufacturer Cree to produce an 450 lumen light bulb that draws just 7 watts and will retail for about $25 door-to-door. In case you're wondering, that's cheaper and more efficient than most any lamp we've seen before. Dean says they've already produced several hundred thousand of the bulbs thanks to a surprise $3 million investment from Google, and plan to have them in the hands of every FIRST kid soon. Keep on fighting the good fight, Dean. %Gallery-106215%
Man with bionic arms dies after car crash
Otto Bock's mind-controlled bionic arms let Austria's Christian Kandlbauer work, play and even drive, but it seems the latter passion may have lead to the 22-year-old's untimely demise. Two days after a road accident where the young man's specially-modified Subaru crashed into a tree, Kandlbauer was pronounced brain-dead and taken off life support late last week. It's not known whether the prosthetic arms themselves had anything to do with the crash -- one was found ripped from his body at the scene -- but both he and his vehicle were cleared to drive by local authorities after passing a number of tests. Honestly, it's a tragedy for science and humanity either way.
DARPA-funded prosthetic arm reaches phase three, would-be cyborgs celebrate
Last we heard from Johns Hopkins University's Applied Physics Laboratory, it wanted a neurally-controlled bionic arm by 2009. Needless to say, the school overshot that goal by a tiny bit, and have now been beaten (twice) to the punch. But DARPA sees $34.5 million worth of promise in their third and final prototype, which will enable the nine pound kit (with 22 degrees of freedom and sensory feedback) to begin clinical trials. Rechristened the Modular Prosthetic Limb, it will be grafted onto as many as five real, live persons, the first within the year. Using the targeted muscle reinnervation technique pioneered at the Rehabilitation Institute of Chicago, patients will control these arms directly with their thoughts, and for their sakes and the fate of humanity, hopefully not the other way around. Press release after the break.
DARPA-funded bionic arm gets second prototype
Researchers at the Johns Hopkins University Applied Physics Laboratory, no strangers to reaching for seemingly unattainable goals in medical science, have set their sights on what some consider to be the ultimate pursuit of modern prosthetics: a bionic arm that moves, looks and feels like its human counterpart. And they want to do it by 2009. An earlier prototype of the arm, the Proto 1, was shown in April of this year, and now the team of scientists is scrambling to ready the arm's second iteration, the Proto 2, in time to show it off this week at the 25th Darpa Systems and Technology Symposium (where it will likely be joined by Dean Kamen's Darpa funded bionic arm). Researchers hope that the prothesis, which is currently controlled by skin-surface-attached myoelectric sensors, can be made more intuitive by adding injectable sensors, which send increased amounts of signals (and have improved clarity) allowing for greater control of the arm. In time, the team hopes to move to nerve-attached electrodes, or electrode arrays implanted on the brain, which will eventually allow for full user dexterity.[Via Wired]
DARPA's prosthetic challenge nets first prototype
Less than a year after challenging researchers to develop a bionic arm that looks, feels, and works like a real arm by 2009, DARPA's Revolutionizing Prosthetics Program has now netted its first prototype, PhysOrg reports, with one patient already putting the arm through its paces. Developed by a team at Johns Hopkins University's Applied Physics Laboratory, the appropriately-dubbed Proto 1 system not only consists of a prosthetic arm, but a virtual environment that patients can use to get accustomed to it. Like other similar systems, the Proto 1 makes use of residual nerves in the patient to control the arm, which also allows for them to receive a sensation of grip strength and touch. That apparently makes the arm precise enough to remove a credit card from a pocket, with the arm also boasting a "free swing mode" that allows for a more natural movement when the patient is walking. While Proto 1 seems to have already been enough to attract interest from various government agencies, the researchers don't look to be resting on their laurels, with them already hard at work on Proto 2.
First woman gets bionic arm
As The Washington Post reports, 26-year old Claudia Mitchell has become the fourth person and first woman to get outfitted with a bionic arm (well, besides Lindsay Wagner), with which she's able to perform functions simply by thinking about them. The arm was designed by researchers at the Rehabilitation Institute of Chicago -- who are part of a larger project funded by DARPA -- and works by detecting the movement's of Mitchell's chest muscle, which has been rewired to the nerves that once served her left arm. Eventually, researchers say, the arm could even give Mitchell the sense of touch, with electrodes in the hand sending signals to her chest skin, which her brain would recognize as a sensation. This being part of a DARPA project though, we're sure they're also working on things they're not telling us, like crazy swinging grappling hook action.[Thanks, Spluch]
