Robot tail developed to balance out human body

Published

on

A robotic tail that claims to balance out the human body could be used instead of a cane to help prevent elderly people from falling over.

The strap-on appendage, known as Arque, has been developed by researchers at Keio University in Japan.

It is inspired by a seahorse’s tail, which is strong enough to withstand predators’ bites but flexible enough to grip things in its environment, like coral.

The tail can be be adjusted to fit whoever is wearing it by adding or removing modular “vertebrae”, the Fast Company reports .

Small weights can also be inserted inside each vertebrae to help offset the wearer’s weight.

This helps the wearer to stay balanced when moving quickly or carrying heavy objects, according to the researchers.

Once the Arque tail is properly adjusted to the wearer’s height and weight, it acts like a counterbalance.

Artificial muscles inside the robotic tail control its movement by contracting and expanding using an external pressurised air system that resembles a lawn mower or giant vacuum.

Because the prototype tail has to remain tethered to this system, the wearer is not able to move very far using it.

However, if the researchers were to find a way to make it mobile, it could act as a support for labourers who have to carry heavy loads, or as an assistive device for people who have trouble balancing.

It could also be used in gaming to throw the user off-balance, making a game feel more realistic.

“For most mammals and vertebrate animals, tail plays an important role for their body providing variant functions to expand their mobility, or as a limb that allows manipulation and gripping,” said Yamen Saraiji, Project Senior Assistant Professor at the Keio University Graduate School of Media Design.

“In this work, Arque, we propose an artificial biomimicry-inspired anthropomorphic tail to allow us alter our body momentum for assistive, and haptic feedback applications.”

The tail was presented last week at the  2019 SIGGRAPH conference in Los Angeles , which focuses on graphics, gaming, and emerging technology.

Chicago will test Samsung’s DeX in-vehicle solution in cop cars

Published

By

Samsung created an in-vehicle version of its DeX platform in hopes that it can replace the computers cops and first responders have to carry around. Now, the Chicago Police Department has announced that it’s taking the system for a spin to see if it can truly be an effective companion for law enforcement officers. CPD Superintendent Eddie Johnson said nearly half of all the officers in the city already have department-issued Samsung phones. When the pilot launches, they’ll be able to access police apps on their vehicle’s dash-mounted display simply by docking their phones.

The pilot test will first roll out to officers from CPD’s 11th district this year. According to Samsung’s announcement, the DeX system will allow them to accomplish tasks like accessing computer-aided dispatch and other CPD systems to conduct background checks from their cars. Further, they’ll be able to immediately attach any photo or video evidence they take with their phones to their reports.

“The old computers had to stay in the cars,” CPD Bureau of Technical Services chief Jonathan Lewin explained. “With this solution, it really creates an ecosystem that takes all the technology and makes it available to officers on the street in real-time and at significantly less cost than we are paying now.”

Samsung says authorities could also use DeX docks in police stations, allowing officers to pick up where they left off on their phones or their cars as soon as they get back. It’s not clear if CPD is also considering using DeX in their headquarters, though — that might depend on how the pilot testing goes.

Huawei has built the Disneyland of tech R&D

Published

on

By

A couple hours outside Huawei’s old headquarters in Shenzhen, China, the company has built a new campus in the city of Dongguan to eventually house 25,000 R&D employees. But this is no sprawling network of glass towers – it’s composed of 12 mini-districts built to look like a different European city, all linked by a full-size train.

In other words, it’s a lot like a Disneyland for tech research.

Walt Disney’s famous park is around 85 acres (0.34 square kilometers), but this research center is four times the size at 296 acres (1.2 square kilometers) – which grows to 1,976 acres (8 square kilometers) if you include the factories across an adjacent lake. Each mini-district – allegedly called ‘towns’ by some Huawei employees – has grandiose buildings, cobbled or bricked streets and landscaped greenery. 

Huawei invited tech media out for a casual tour of the grounds, and TechRadar got a close-up look. We started at a coffee shop and got on a two-car train in a bold orange with brass accents, looking straight out of Industrial-era Europe.

We breezed past areas patterned after Paris, Burgundy, Heidelberg, Cesky Krumlov, and Bologna, packed with ‘towns’ in the style of, and laid out like, each city – some so large, they might as well be castles. It was completely impressive, yet out of place amid the lush Chinese flora and the shabby residential high-rises in the distance. Image 1 of 5

The effect was surreal – a dizzying dissonance between carefully-constructed medieval and Renaissance European buildings that would still function as everyday workplaces. Each member of our media group stared agog as we took the long orange train beyond the completed ‘towns’ (seven of twelve are work-ready, five years after construction started ) to get a sense of the installation’s scale.

We were left with the obvious question: Why?

Huawei’s workplace ‘Disneyland,’ a new center of research

Or to reframe the inquiry: why not just make a modern glass-and-grass campus like the other tech titans? Our guide explained the philosophy behind the Dongguan facility: Huawei founder and CEO Ren Zhengfei wanted employees to work in a place they found peaceful, which is a far cry from the busy metropolitan sprawl in Shenzhen or Dongguan. Image 1 of 5

If true, that sentiment – and the sheer resources spent to bring this city-replicating vision into reality – evokes the whimsy and dedication Walt Disney swirled together to make Disneyland. “Here age relives fond memories of the past, and here youth may savor the challenge and promise of the future,” Disney famously said at the park’s opening in 1955 in a brief dedication. 

Sixty-odd years later, those words could strangely apply to Huawei’s Dongguan R&D campus. 

On our visit, tech media were introduced to the company’s myriad applications of its tech, from augmenting existing industries with 5G to making cities ‘smart’ with enough sensors to monitor power consumption, air quality, and even the capacities of individual trash cans. And, yes, streamlining the networks behind security camera systems (to help missing children and crowd control, a Huawei tour guide said) as well as networks (and sometimes chips) behind facial recognition software.

Of course, the company’s tech innovations aren’t just made in Dongguan: that still-unfinished facility is one of 16 global R&D centers. Nine of them are in China, but whereas the others have around 10,000 employees each, the Dongguan installation will house around 25,000 once it’s finished – combined, the R&D contingent is over half of Huawei’s 188,000 employees.

But those other R&D facilities weren’t built as a paean to culturally significant European cities. It’s unclear if the Dongguan campus was built so extravagantly to lure employees or to satisfy the eccentric whims of upper staff (if not Zhengfei himself) – or both, or neither. What is clear: if this was built in the US, it would be soundly criticized as a needlessly ornate and expensive feat of engineering – just like Disneyland had been before it showed up its critics.

Harvard scientists design robot shorts to make running less horrible

Published

By

Researchers at Harvard University have designed a pair of robot shorts that could make running, a tortuous activity for many of us, much easier. The robot shorts are actually a lightweight hip exosuit that can make you feel about 16 pounds lighter while walking and about 12 pounds lighter while running. 

The suit does this by reducing the wearer’s metabolic cost, or energy spent, by over 9% when walking and 4% when running, the researchers said of their findings, published in Science on Monday. The robot shorts can switch between walking and running seamlessly. When you put it on and start to move, it assists you with a “cable actuation system.” The cables apply a tensile force between the waist belt and thigh wrap to create an external extension torque at the hip joint that works with your glutes, according to the release. 

“We were excited to see that the device also performed well during uphill walking, at different running speeds and during overground testing outside, which showed the versatility of the system,” study lead Conor Walsh said in a release.  

The suit could be helpful to anyone needing to cover large distances — rescue workers searching disaster areas, US Army soldiers or Marines marching, or hikers making a long trek. 

“It is very satisfying to see how far our approach has come,” Walsh said in the release, “and we are excited to continue to apply it to a range of applications, including assisting those with gait impairments, industry workers at risk of injury performing physically strenuous tasks, or recreational weekend warriors.”

The research team wasn’t immediately available for further comment.
