    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.

    Kevlar cartilage could help you recover from joint injuries

    It can be difficult to fully recover from knee injuries or other damage to your joints, if just because there hasn't been an artificial replacement for cartilage that can withstand as much punishment as the real thing. That may not be an issue in the long run, though: scientists have developed a Kevlar-based hydrogel that behaves like natural cartilage. It mixes a network of Kevlar nanofibers with polyvinyl alcohol to absorb water at rest (like real cartilage does in idle moments) and become extremely resistant to abuse, but releases it under stress -- say, a workout at the gym.

We also take a look at a bionic knee from "Monster" Mike Schultz designed for Moto-crossing lower-leg amputees. The Mythbusters find out if Walter White's machine gun trap could actually work (hint: omfg, does it ever) and a Parakeet learns to speak droid because Star Wars just won't go away. If you come across any interesting videos, we'd love to see them. Just tweet us with the #ICYMI hashtag @engadget or @mskerryd.

  • Power Knee motorized prosthetic officially available in US, Europe -- race of cyborgs still in infancy

    We reported on Ossur's robotic prosthetic back in 2009, and now amputees in Europe and the United States have become the first official recipients of the Power Knee. According to the company, "the world's first and only motor-powered prosthetic knee" was recently approved for reimbursement by the German National Health System, covered by private insurance in France and the UK, and picked up by select healthcare providers in the US. Power Knee combines "artificial intelligence," motion sensors, and wireless communication to learn and adjust to the walking style of its users -- that's one small step for real-life cyborgs and one giant leap for prosthetic technology.

  • Dutch prisoners could get remote knee locks

    The Dutch Ministry of Justice recently announced that special knee locks to prevent prisoner escapes could be tested later this year if parliament gives its approval. In the Netherlands, a "furlough" system is used to gradually reintroduce prisoners that have committed serious offenses back to society: instead of letting prisoners out when their term ends, they are accompanied by a guard to visit relatives, and gradually given more freedom until it is deemed that they are ready for unsupervised parole. Unfortunately, there have been several cases where prisoners on leave committed serious offenses like rape and murder by slipping away from their guards. The purpose of this test is to see whether a knee locking system -- which prevents a prisoner from moving if they move a certain distance away from their guard -- can prevent these kind of unfortunate cases. As draconian as this system may sound, it's probably the most humane of all the solutions that were looked at: prisoners could potentially have had to wear gadgets that gave them electric shocks or injected drugs to prevent them from escaping. The best part about this whole case is what justice ministry spokesman Wim van der Weegen compared the system to: illegally parked cars. Probably not the best analogy he could have used -- badly parked car = potentially inconvenient. Escaped prisoner = potentially capable of murder -- but we'll give Wim the benefit of the doubt this time, and mark it up as lost in translation.[Thanks, Joel]

  • Wii-related injury roundup

    It didn't take too long for the first Wii-related injury to surface, and it was even shorter before Wiimotes folks starting breaking things with their wild flinging antics, but when your product spurns the creation of an entire website devoted to users getting banged up when misusing the controller, now that's an accomplishment. Of course, it's probably safe to assume that at least half these Wiinjuries are nothing more than backyard boo-boos that folks translated into Wiincidents to get their 15 minutes of fame, but regardless, when Nintendo sends out emails and offers beefier Wiimote straps to those having problems, at least some of this stuff has to be legitimate. First up is a high-heel-wearing dame who apparently dislocated her knee while going for the smash in Wii Tennis, but the remedy to this happening again should really be quite apparent. Next we've got a rowdy customer service guru who actually swung the Wii-bat so hard, it purportedly snapped something within his arm. Lastly, we've got a Agassi wannabe who didn't exactly pay attention to the overhead (glass) light fixture before serving an ace, and now he's reportedly got the bloodshed (and repair bills) to show for it. The moral of the story is that the Wiimote can be a potent weapon and injury liaison if not used properly, but hey, we can't deny the humor in folks taking themselves out when going FTW.Read - Dislocated Knee, via JoystiqRead - Broken ArmRead - Sliced HandRead - More Examples of Wiimote carelessness
