DARPA is giving war vets first access to LUKE bionic arms
DARPA's sophisticated LUKE bionic arm is ready for production, eight years after its development began and a couple of years after it was approved by the FDA. Before the bionic limb makes the transition into a commercial product, though, the military division is giving war veterans access to its initial production run. DARPA's Biological Technologies Office director Justin Sanchez has recently delivered two LUKE arms to the Walter Reed National Military Medical Center for use by a couple of vets in need of a prosthetic limb.
Powered prosthetics turn mundane tasks into monumental feats
Lukas Kalemba was walking home with some friends after a night of partying and drinking in Dortmund, Germany, in 2003. While crossing a bridge along the way, he stopped to rest but lost his balance and fell over. In an attempt to break his fall, he instinctively reached out and grabbed a wire that stretched across. It kept him from falling 20 feet to the ground immediately but the wire sent a high-voltage current through the left side of his body, causing irreparable damage to his leg. Kalemba became an above-the-knee amputee when he was 19 years old. He was in an induced coma for three weeks until the doctors brought the pain down to a manageable level. "The first time I noticed it was in the hospital when I stood up at night to go to the toilet," he says. "I wanted to stand on my left foot [but] I crashed on the floor."
Prosthetic arms inspired by 'Deus Ex' are coming next year
Remember that prosthetic arm, inspired by Metal Gear Solid, that Konami developed for a British amputee? Well, it seems the company has started a trend. Square Enix and Eidos-Montréal have now teamed up with Open Bionics, a specialist in low-cost prosthetics, to develop some designs based on the world of Deus Ex. The franchise delves deep into a possible future where human augmentation is commonplace, changing society and warfare in equal measure. Two arms -- one based on Adam Jensen, the hero of Mankind Divided, another on the wider Deus Ex universe -- will be released next year as royalty-free designs that anyone can use.
DARPA-funded mind-controlled robotic arm now works a lot better
At Expand NY in November, DARPA Director Arati Prabhakar talked about the erm, friendlier projects the agency is funding, including a mind-controlled robotic arm tested by Pittsburgh native Jan Scheuermann. Her test run has recently ended, but the University of Pittsburgh researchers in charge of project have published a paper detailing how much the limb has improved over the past two years. Before they took off Jan's implants, she could already move not just arm itself, but also its wrist and fingers -- she reportedly even beat her brother at a rock-paper-and-scissors game. "Overall, our results indicate that highly coordinated, natural movement can be restored to people whose arms and hands are paralyzed," said Pitt School of Medicine professor Andrew Schwartz, Ph.D.
Scientists build a robot arm that catches objects in the blink of an eye
Humans are good at catching fast-moving objects -- just ask any baseball fan. Robots typically lag behind, however, which is why the École Polytechnique Fédérale de Lausanne (EPFL) has developed a robot arm with the reaction time needed to catch just about anything. After learning the basic concepts by imitating human behavior, the machine uses its cameras to predict the path of a flying object and grab it in less than five hundredths of a second -- roughly as fast as it takes you to blink. It can even adapt to objects whose center of gravity is likely to shift around, such as a half-full drink bottle.
DARPA developing muscle-controlled prosthetic limbs that can feel (video)
DARPA's no stranger to bionic limb research, however two new projects under the agency's RE-NET program focus on improving amputees' link to their prosthetics. RE-NET aims to develop the technology that will connect artificial limbs to existing nerves and muscles. Once that's achieved, users will be able feel with the prosthetic as well as move it as they would a real arm or leg, unlike another project focused on one-way control. Head past the break to watch videos documenting the clinical trials of both studies -- the arms in the clips aren't quite the life-like limbs DARPA promised back in 2006, but they sure are mighty impressive.
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]
