Scientists develop neuroprosthetic tech that amputees don't need to learn
For those working in the field of neuroprosthetics, the ultimate goal is to give amputees with artificial limbs natural, intuitive and real-time movement. Indeed, advances in the field have led to mind-controlled systems and even those that create kinaesthetic feedback, but so far such technologies require a great deal of learning and practice by the amputee. Now, however, scientists from the University of Michigan have developed a neuroprosthetic technology that restores intuitive movement to amputees from the get-go -- no learning required.
Scientists make jellyfish swim faster to prepare for deep-sea exploration
Scientists at Caltech and Stanford University want to turn jellyfish into deep-sea explorers that could be directed around the ocean, recording info as they travel. In a paper published in the journal Science Advances, the team explains how they've developed a tiny, microelectronic prosthetic that can be attached to jellyfish, causing them to swim faster and more efficiently.
New prosthetic legs let amputees feel their foot and knee in real-time
There's been a lot of research into how to give robots and prosthesis wearers a sense of touch, but it has focused largely on the hands. Now, researchers led by ETH Zurich want to restore sensory feedback for leg amputees, too. In a paper published in Nature Medicine today, the team describes how they modified an off-the-shelf prosthetic leg with sensors and electrodes to give wearers a sense of knee movement and feedback from the sole of the foot on the ground. While their initial sample size was small -- just two users -- the results are promising.
MIT’s sensor-packed glove helps AI identify objects by touch
Researchers have spent years trying to teach robots how to grip different objects without crushing or dropping them. They could be one step closer, thanks to this low-cost, sensor-packed glove. In a paper published in Nature, a team of MIT scientists share how they used the glove to help AI recognize objects through touch alone. That information could help robots better manipulate objects, and it may aid in prosthetics design.
Open Bionics’ 3D-printed prosthetic arm is now available in the US
One year after Open Bionics began selling its 3D-printed Hero Arm prosthetic in the UK, the bionic arm is available in the US. Open Bionics has made a name for itself as a start-up specializing in low-cost prosthetics, and you might remember it as the company behind arms inspired by Iron Man, Star Wars, Frozen and Deus Ex. But until now, the Hero Arm has only been available in the UK and France.
AI-tuned robotic knee helps amputees walk within minutes
Amputees who receive robotic limbs can't usually start using them right away. It typically requires hours of manual tweaks to adapt to their particular movement styles, and they may need to come back for more if anything changes. Soon, however, they might only need the briefest tweaks to get moving. Researchers have crafted an AI system that can tune a robotic knee (not pictured) to allow walking on level ground within 10 minutes. It uses a trial-and-error algorithm to recognize patterns in sensor data, set initial safety limits, and learn patterns that match stable, smooth walking motions.
Smart prosthetic ankle can adapt to uneven ground
Prosthetic limbs have evolved considerably from the rudimentary wooden appendages of just a few decades ago. They can be bionic, brain-controlled and loaded with features -- and even mimic the sense of touch. But they're still a way off truly replicating the real thing, largely because of issues imitating the many subtle movements and sensations that come naturally to real limbs. Now, however, a new prosthetic ankle is overcoming these challenges.
Open Bionics’ latest 3D-printed arm goes on sale next month
Open Bionics announced today that its 3D-printed Hero Arm prosthetic will be available for purchase in the UK next month. The company's founders started Open Bionics because they were interested in developing prosthetic limbs that were less expensive than traditional options, which typically cost tens of thousands of dollars. Using 3D-scanning and 3D-printing, they aim to produce more affordable options that can be constructed much more quickly than other prosthetic devices. In the past, they've developed Star Wars-, Iron Man- and Frozen-themed prosthetic hands for children as well as a Deus Ex-inspired arm.
Brain interface adds sense of presence to bionic limbs
It's been possible for a while to control bionic limbs with your brain, but there's been something missing: kinesthetic feedback, or the nervous system signals that give your limbs a sense of presence. You frequently have to stare at your artificial arm to ensure that you're grabbing a cup instead of operating on instinct. That elusive quality may soon be a regular staple of prosthetics, however. Researchers have developed a neural interface that generate this feedback and make bionic feel like they're part of your body.
Rugged e-skin can heal its cuts and scrapes
Scientists dream of prosthetics and robots with electronic skin that can convey heat and pressure just like the real thing, but there's a big problem getting in the way: the outside world. Bumps and scrapes can damage these sensors, and it's not really practical to toss these skins in the trash when they're no longer useful. UC Boulder researchers hope to fix that. They've developed an e-skin that can communicate temperature and pressure, but is both self-healing and fully recyclable. You could take a cut on a synthetic arm without panicking, and reuse any damaged 'tissue' to make replacements.
Researchers create prosthetic hand that offers more lifelike dexterity
Researchers at Georgia Tech have developed a prosthetic hand inspired by the bionic one given to Star Wars' Luke Skywalker. What sets this one apart from other prosthetics is the amount of dexterity it offers, allowing users to move individual fingers at will. With it, Jason Barnes, the amputee working with the researchers, was able to play piano for the first time since losing part of his arm in 2012.
DARPA is helping six groups create neural interfaces for our brains
Elon Musk isn't the only one looking to rummage around inside your skull. DARPA announced on Monday that it has selected its five grant recipients for the Neural Engineering System Design (NESD) program, which it began at the start of this year. Brown University, Columbia University, The Seeing and Hearing Foundation, the John B. Pierce Laboratory, Paradromics Inc and the University of California, Berkeley will all receive multi-million dollar grants to help develop various aspects of the emerging technology.
‘The Third Thumb’ is for all the times two just aren’t enough
How many times have you wished for a third hand while trying to carry too many things? Well, you can't have that yet because it's not a thing (at least not an available thing), but maybe you can get yourself another thumb, which is almost as good. Dani Clode, a graduate student at the Royal College of Art in London, created The Third Thumb, a 3D-printed prosthetic that straps onto your hand.
Adding a second pair of arms is as easy as putting on a backpack
There's only so much you can do with two arms and hands. That's basic science. But what if you could add extras without the need for ethically shady surgery or trading your apartment for a hovel in the shadow of a nuclear power plant? That's what researchers from Keio University and the University of Tokyo hope to achieve with their "Metalimbs" project. As the name suggests, Metalimbs are a pair of metal, robotic arms that doubles the amount of torso-extremities and worn with a backpack of sorts. And unlike thought-powered prosthetics we've seen recently, these are controlled not with your brain, but your existing limbs. Specifically, your legs and feet.
ICYMI: A prosthetic hand with two senses
Today on In Case You Missed It: We get our first close-up look at Saturn's rings thanks to the Cassini spacecraft -- which just completed the first of its twenty-two passes through the planets' famed hoops. NASA stitched together the images from the craft to give us Earthlings an incredible first-person (first-spacecraft?) point-of-view of the recent dive, which began at the north pole of the planet and moved down its side. The imaging team working on Cassini's trips expects to get even better data from the subsequent trips, which will gather information on Saturn's gravity and magnetic fields.
This prosthetic arm is powered by Bluetooth and your mind
Robotic limbs aren't a new technology, though the range of motion and strength of such limbs continue to improve. Controlling prosthetics with your mind is another area of refinement, but they're typically connected directly to a patient's brain. A new technique where the robotic arm clicks directly to the bone, however, is showing promise. Johan Baggerman is the first patient in the Netherlands to get a click-on prosthetic arm that he can control with his mind.
DARPA has laid the groundwork for thought-powered prosthetics
New research from the government's mad science wing, DARPA, could make life an awful lot easier for people who use prosthetic limbs. You see, DAPRA has devised what it calls the "Atomic Magnetometer for Biological Imaging in Earth's Native Terrain." Or, "AMBIIENT" if you're into the whole brevity thing.
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.

Then they'll talk about all the work that went into Engadget's five part series covering the world's first cyborg games, Superhumans and look at VR's ability generate empathy.
Human and machine become one for birth of the Cybathlon
On a bright Tuesday morning, about six miles north of Zürich, an ice-hockey team skates onto a rink for a practice round. Each player, dressed in a white jersey and matching protective gear, slides a puck in the direction of a heavily padded goaltender. The little discs swish across the floor in a black blur before smashing against the peripheral walls in loud thuds that echo throughout the Swiss Arena. The arena is home to the Kloten Flyers, Switzerland's leading hockey team, who regularly play to a packed house. But in less than a month, the icy floor inside the country's largest indoor venue will transform into a race course for a different kind of sporting event. On Oct. 8th, the stadium will open its doors to the world's first Cybathlon, a multidiscipline competition for people with disabilities who use bionic technologies to augment their bodies.
