Cyberlegs project wants to equip amputees with robotic limbs
You'll see a lot more instances of robotic arms in the news, but it doesn't mean high-tech prostheses for the lower limbs don't exist. The Cyberlegs project, for instance, is developing robotic legs that can help amputees move and walk more naturally. Each system is comprised of smart shoes equipped with pressure sensors and inertial measurement units, the limb itself, as well as a component and algorithm that can decode how the user intends to move. It can, for instance, tell if the user wants to start walking, to get up or to sit down -- based on the amputee's habits -- providing the proper support for each action. Users that need even more help can also be fitted with an accompanying pelvic brace that can assist them in moving their hips.
Researchers take one step closer to neural-controlled bionic legs for safer mobility
We've seen our fair share of prosthetic arms and computer interfaces operated with little more than the firing of a synapse, but legs? They're a different story: balancing and propelling a sack of (mostly) flesh and bone is a much more complicated task than simply picking up a sandwich. Thankfully, the Rehabilitation Institute of Chicago's Center for Bionic Medicine is now one step closer to thought-controlled lower-limb prosthetics. As pictured here, the researchers' early simulations showed that amputees could control a virtual knee and ankle with 91-percent accuracy, by way of pattern recognition software to interpret electrical signals delivered through nine different muscles in the thigh -- patients think about moving, thus lighting up the nerves in varying patterns to indicate different motions. The ultimate goal is to hook up bionic legs through the same way, which would offer a greater range of motion than existing prosthetics, making tasks like walking up and down stairs safer. Now all we need is a quadruple amputee willing to pick up a badge and slap on an eye-tracking microdisplay.
"Bionic" goose happy to have new leg, disappointed by lack of retractable laser cannon
Not wanting to let Betty the gosling goose meet an untimely fate, a UK vet outfitted the anatidae with a bionic leg, allegedly the first operation of its kind in the world (not counting Robot Chicken, of course). She's currently learning to walk again at nearby Tiggywinkles Wildlife Hospital at Buckinghamshire. Does she now possess super speed, the ability to make large vaults without using her wings, or a super powerful kick? All signs point to no, but a new lease on life has gotta count for something, right?
