The test was meant to simulate the impacts of being on a speed boat during high seas, an experience that can involve a ton of harsh G forces.
The device has its limits, however, particularly when it’s not used for its intended purpose. While technologically impressive, the Forge brace didn’t allow Rose to dunk a basketball, as he found out to his dismay.
“I was wrong to believe that I could fly and I feel stupid now,” a disappointed Rose said in the video.
Robotic exoskeletons have captivated us for years. They are major tropes in sci-fi movies and video games, and in real-life engineers have been working on them since the 1900s. San Francisco’s Roam Robotics has entered into this space, and Brent Rose tries his hand at stress testing their latest military leg brace.

Russia’s robot manufacturer Promobot told Sputnik it was opening a research and development department and a special laboratory in the country’s Far East for creating hyper-realistic artificial skin for anthropomorphic robots.
Why do so many people get frustrated with their “high-tech” prostheses? Though sophisticated robotics allow for prosthetic joints that can do everything a human can and more, the way we control robotic machines right now doesn’t allow us to operate them as naturally as you would a biological hand. Most robotic prostheses are controlled via metal pads on the skin that indirectly measure muscle action and then make some assumptions to determine what the person wants to do. Whil… See More.
We plan to use MM to provide natural control over prosthetic limbs by leveraging the human body’s proprioception. When you wiggle one of your fingers, your brain senses muscle lengths, speeds, and forces, and it uses these to figure out the position of that finger. This is called body awareness, or proprioception. When someone receives an amputation, if their muscle connections are maintained with what is called the “AMI technique,” their brain still perceives muscle flexion as it relates to joint movement, as if their limb was still present. In other words, they are sensing movement of a phantom limb. To give an amputee intuitive control over a robotic prosthesis, we plan to directly measure the muscle lengths and speeds involved in this phantom limb experience and have the robot copy what the brain expects, so that the brain experiences awareness of the robot’s current state. We see this technique as an important next step in the embodiment of the prosthetic limb (the feeling that it is truly part of one’s body).
Notably, the tracking of magnetic beads is minimally invasive, not requiring wires to run through the skin boundary or electronics to be implanted inside the body, and these magnetic beads can be made safe to implant by coating them in a biocompatible material. In addition, for muscles that are close to the skin, MM can be performed with very high accuracy. We found that by increasing the number of compass sensors we used, we could track live muscle lengths close to the surface of the skin with better than millimeter accuracy, and we found that our measurements were consistent to within the width of a human hair (about 37 thousandths of a millimeter).
The concept of tracking magnets through human tissue is not a new concept. This is the first time, however, that magnets have been tracked at sufficiently high speed for intuitive, reflexive control of a prosthesis. To reach this sufficiently high tracking speed, we had to improve upon traditional magnet tracking algorithms; these improvements are outlined in our previous work on tracking multiple magnets with low time delay, which also describes how we can account for the earth’s magnetic field during portable muscle-length tracking. This is also the first time that a pair of magnets has been used as a distance sensor. MM extends the capabilities we currently have with wired-ultrasound-crystal distance sensing (sonomicrometry, SM) and tantalum-bead-based distance sensing via multiple-perspective X-ray video (fluoromicrometry, FM), enabling us to now wirelessly sense distances in the body while a person moves about in a natural environment.
This #COVID19 is quite weird it just keeps evolving. In a weird way it is pushing evolution through our immune system. The only thing I know that is similar is like the flu or a bigger organism like cancer. Based on this information the virus just keeps evolving not dying off. Among the weird stuff it doesn’t effect cats or most animals or plants. Basically we either need a universal vaccine which is still being developed or we may need quantum radar to kill off the virus in our bodies when it comes out either that or foglet armor to not breathe it in like Ironman. I find it is just an odd virus as essentially it evolves so fast past even human beings abilities to fend it off even with suits it seems to spread so fast that it cannot be completely contained. From dogs that sniff it out it seems sorta everywhere. I know minor things like high dosages of vitamin c work with zinc and probiotics which was the first way to battle it when it didn’t become this whole pandemic because oddly enough it wasn’t a big deal in previous years because the 19th version of the virus. I know some things that kill it off are ultra violet and lysol as well as bleach. So it makes me think it is more a bioweapon where the universal vaccine would work. But oddly enough I am uncertain if it really dies off especially if it is airborne. If we can destroy the virus by reprogramming it to be sterile or innert or even for it to just kill itself off with crispr like we have done with mosquitoes to stop malaria. We can easily make new vaccines which is good but nearly every year or so there is an entirely new version. This isn’t new but it sorta is like the flu. But there are some theories that I sorta have where it seems to be near heat sources where it grows. Like my uncle who had the virus which we had him turn off electricity and also do vitamin c probiotics and zinc which did work. He ended up getting an antibody naturally this way. I personally got the vaccine and found that it does work but when the new delta version came out it did the same as the last one it sorta just randomly evolves for some reason even smells similar but oddly enough it still remains even after all the lysol. So to me it seems like a bioweapon that is self evolving which is we could use the mechanism to essentially evolve ourselves taking the components of it. If this was a nanobot swarm I would say it spreads from radio waves or something but this virus keeps spreading in odd ways like even from the sky. Which sorta makes me believe that it is sorta being manipulated maybe by a signal perhaps or it has its own program inside it. It reminds me of a Grey goo nanobot swarm that keeps evolving but the biological virus version. I mean it could actually be an exterrestial virus there was a meteorite that came around then and odd things that followed from the meteorite like dogs attacking people and cats attacking people even huge mountain lions. Which makes me think of a sorta an invasion of something. We need to maybe get the viruses input and output to find what it is going to do next. All and all seems odd because even other viruses don’t evolve or like fly or spread that fast. Ideally we should have cyborg nanobots running through Ironman in avengers endgame but so far our best better is treating it like the flu pumping out a new vaccine each year till we know a universal vaccine like using henreitta lacks immortal unlimited cell division cells like they did with polio. But till then we need to keep watching the virus as seems sorta more than it appears based on its original version.

The field of neuroprosthetics was around in its earliest stage in the 1950s, but it’s only just starting to show its true potential, with devices that allow amputees to feel and manipulate their surroundings.
A group of researchers from MIT and Shanghai Jiao Tong University, recently collaborated with the goal of making neuroprosthetic hands, which allow users to feel in a more accessible way. The result is an inflatable robotic hand that costs only $500 to build, making it much cheaper than comparable devices, a post from MIT reveals.
The researchers behind the new prosthetic say their device bears an uncanny resemblance to the inflatable robot in the animated film Big Hero 6. The prosthetic uses a pneumatic system to inflate and bend the fingers of the device, allowing its user to grasp objects, pour a drink, shake hands, and even pet a cat if they so wish. It allows all of this via a software program — detailed in the team’s paper in the journal Nature Biomedical Engineering — that “decodes” EMG signals the brain is sending to an injured or missing limb.
Unlimited Tomorrow is pioneering a new age in prosthetics with its 3D-printed robotic arms. Founded in 2,014 by Easton LaChapelle when he was just 18 years old, the company is poised to become a leader in the prosthetic arm industry. Their True Limb device costs less than $8,000 and it’s even cheaper for children, priced at about $4,000.
True Limb is both functional and realistic-looking, serving as a mirror image of the amputee’s opposing limb, even down to the fingertips. And while the prosthetic arm is 60–90% cheaper than traditional prosthetics, many users say it’s far superior to market alternatives. What’s the secret? Unlimited Tomorrow uses a totally remote, custom process that cuts out middlemen to produce prosthetics completely in-house.
For the 40-million worldwide amputees in need of prosthetic limbs, this remote, personalized, and affordable process for fitting prosthetics means hope for a better future.

VLADIVOSTOK, Russia — To see Russia’s ambitions for its own version of Silicon Valley, head about 5,600 miles east of Moscow, snake through Vladivostok’s hills and then cross a bridge from the mainland to Russky Island. It’s here — a beachhead on the Pacific Rim — that the Kremlin hopes to create a hub for robotics and artificial intelligence innovation with the goal of boosting Russia’s ability to compete with the United States and Asia.
On Russia’s Pacific shores, the Kremlin is trying to build a beachhead among the Asian tech powers.
