Cheap At $40,000: Phoenix Exoskeleton Gives Paraplegics Legs to Walk With

Fast Company highlights the cheap-for-the-price Phoenix exoskeleton, created by University of California Berkeley professor (and Berkeley Robotics and Human Engineering Laboratory director) Homayoon Kazerooni and a team of his former grad students at SuitX, a company Kazerooni founded in 2013. Set to sell for $40, 000 when it goes on sale next month, the Phoenix sounds expensive — except compared to the alternatives. For paraplegic patients, there are a handful of other powered exoskeletons, but they cost much more, and are engineered for more than the modest goals of the Phoenix, which allows only one thing: slow walking on level ground. That limited objective means that the rig is light (27 pounds), and relatively unobtrusive. Kazerooni says that he’d like the price to go down much further, too, noting that all the technology in a modern motorcyle can be had for the quarter of the price. A slice: [The] only driving motors in Phoenix are at the hip joints. When the user hits a forward button on their crutches, their left hip swings forward. At this moment, the onboard computer signals the knee to become loose, flex, and clear the ground. As the foot hits, the knee joint stiffens again to support the leg. This computer-choreographed process repeats for the right leg. As it happens, this hinged knee joint has another benefit. If the wearer hits something midstep, like a rock or a curb, a powered knee would blindly drive the leg forward anyway, likely leading to a fall. The hinge naturally absorbs such resistance and allows the wearer a chance to compensate. Read more of this story at Slashdot.

Microsoft wants to put data centers at the bottom of the sea

Microsoft is on a mission to put its server farms at the bottom of the ocean . That might sound self-destructive, but there’s method in the madness — such an approach, the company believes, could make data centers faster, greener and easier to set up. In August last year, engineers placed an enormous steel capsule 30 feet underwater in the Pacific Ocean. Inside was a single data center rack, enveloped in pressurised nitrogen to keep it cool. The crew couldn’t reach it, at least not physically, but it didn’t matter — the setup worked, going so far as to run commercial tasks for Azure. The prototype submersible is called Leona Philpot, another nod to the Halo universe (after Cortana and Spartan). As the New York Times reports , the pod was kitted out with 100 sensors to measure every aspect of the underwater conditions — pressure, humidity and, perhaps most importantly, motion. The idea is that similar capsules could exist beneath the surface, linked to one another in a chain, and continually generate energy from the moving seawater. Looking ahead, there’s also hope that the aquatic environment could be used to naturally cool the racks. These aren’t the only advantages though. Server farms usually exist inland, far away from metropolitan areas. From a performance standpoint, their locations are inefficient for people living near the coastline — placing data centers offshore could, in theory, reduce latency for these places. Microsoft also believes that a smaller design could reduce installation times, from two years down to a staggering 90 days, making its operations cheaper and more flexible. The capsules themselves could also adopt new, innovative rack designs that don’t need to consider human interaction. There are environmental concerns, but Microsoft appears to be tackling them. It wants the data centers to be fully recyclable, and says its current prototype emits an “extremely” small amount of heat into the surrounding waters. Still, for people that love the ocean, this could be seen as yet another encroachment on mother nature. In the meantime, Microsoft has pulled Leona Philpot ashore — covered in barnacles, unsurprisingly — while it designs a new prototype that’s reportedly three times larger.

Electronic music gets its own televised awards show

Variety is reporting that Fox will broadcast the inaugural Electronic Music Awards on Saturday, April 23rd at 8pm. The network has teamed up with superstar DJ Paul Oakenfold to create the event as a celebration of the genre. It’ll feature red carpet coverage, interviews, the ceremony itself and performances from the world’s biggest artists. Read between the lines and you’ll assume that the move was born out of frustration with the Grammy’s traditional disdain for electronica. As Oakenfold says, he’s “thrilled to be part of an awards show that finally ” (emphasis ours) “recognizes and celebrates… one of the biggest music genres in the world.” You can feel the heat radiating off that burn from a mile away. Stuff that’s been made by a computer has always been treated as a poor cousin of things that are made more “traditionally.” Despite its pervasiveness, CGI gets a bum rap compared to practical effects , and it’s taken years for eSports to receive any degree of recognition from traditional broadcasters . Take a cursory look at the Grammy award categories and you can see where Oakenfold’s annoyance comes from. For instance, R&B and jazz both get five categories a piece, while electronic has to share a table with dance and has just two measly categories. Which seems a little bit unfair, don’t you think?

France To Pave 1000km of Road With Solar Panels

An anonymous reader writes: France is planning on a project to build 1000 kilometers of road with specially designed solar panels. This project will supply 5 million people in France with electricity if it is successful. Though many solar experts are skeptical of this project, the French government has given the go-ahead to this venture. According to France’s minister of ecology and energy, Ségolène Royal, the tender for this project is already issued under the “Positive Energy” initiative and the test for the solar panels will begin by this spring.The photo voltaic solar panels called “Wattway” which will be used in the project are jointly developed by the French infrastructure firm “Colas” and the National Institute for Solar Energy. The specialty of “Wattway” is that its very sturdy and can let heavy trucks pass over it, also offering a good grip to avoid an accident. Interestingly, this project will not remove road surfaces but instead, the solar panels will be glued to the existing pavement. Read more of this story at Slashdot.

VR games Audioshield, Hover Junkers lead latest wave of HTC Vive stunners

SEATTLE, Washington—How many times can a publication attend a virtual reality showcase and walk away stunned by something it’s never seen before? Judging by the past few years of Ars’ VR explorations, quite a few . As such, we don’t blame readers who might say, “Tap the VR brakes, Ars.” Still, this week’s SteamVR Developer Showcase event is forcing us to reach into the hyperbole bag once more. The event blew us away thanks to a number of never-before-seen stunners, along with previously announced HTC Vive titles that have only gotten better in the oven before their retail launch later this year. (April, we hope .) “Room scale” VR is a tough sell, especially for people whose homes don’t easily accommodate enough cleared-out space for walking around with a headset on, but while we’ve already been impressed with what the platform can support, we didn’t think we could be impressed any further. We were wrong. Read below to see why we’re currently trying to put our kids, pets, beds, and significant others up for adoption—so we can hurry up and make space for this incredible new platform. (Sorry, sweeties.) Read 42 remaining paragraphs | Comments

Ask Slashdot: Why Are Major Companies Exiting the Spam Filtering Business?

broswell writes: For years we used Postini for spam filtering. Google bought Postini in 2007, operated it for 5 years and then began shutting it down. Then we moved to MX Logic. McAfee bought MX Logic, and McAfee was purchased by Intel. Now Intel is shutting down the service. Neither company chose to raise prices, or spin off the division. Anyone want to speculate on the reasons? Read more of this story at Slashdot.

Jailbreak Turns Cheap Walkie-Talkie Into DMR Police Scanner

An anonymous reader writes: Last Shmoocon, famous reverse engineer Travis Goodspeed presented his jailbreak of the Chinese MD380 digital handheld radio. The hack has since been published at GitHub with all needed source code to turn a cheap digital radio into the first hardware scanner for DMR digital mobile radio: a firmware patch for promiscuous mode that puts all talk groups through the speaker including private calling. In the U.S. the competing APCO-25 is a suite of standards for digital radio communications for federal users, but a lot of state/county and local public safety organizations including city police dispatch channels are using the Mototrbo MotorolaDMR digital standard.

These SteamVR games will make or break virtual reality

In one month, the HTC Vive will be available for pre-order , giving consumers a chance to buy the first room-scale virtual reality system with full head and hand motion tracking. It sounds great, but what are you going to play with it? Valve knew you were going to ask that — which is why it hosted the SteamVR Developer Showcase in Seattle this week. In all, the company showcased twelve games that stood out as some of the best VR experiences Vive owners can have in 2016. Better still? There’s not a bad egg in the bunch — I’ve played all of them, and I already want to play all of them again. Believe or not, the fact that I can say that about Valve’s showcase is huge. Oculus’ Palmer Luckey once told me that the only thing that could kill virtual reality is bad virtual reality — and he’s right. The sense of presence one feels in consumer VR is so hard to articulate that the challenge of explaining it to new users has become something of an inside joke to the industry. Every developer I asked at the event told me the same thing: If you want a newbie to understand why VR matters you have to make them try it . If they do, and the experience is bad, they’ll write it off as a gimmick. That’s why events like the SteamVR developer showcase are so important: These are the first, best experiences consumers will have. These are the games that will make or break the virtual reality industry. Thank goodness they don’t suck. Part of what makes most of these SteamVR launch titles work is that there’s no learning curve . Thanks to Valve’s lighthouse laser tracking tech and the HTC Vive’s motion controller, interacting in VR is pretty much like living your normal life. If you want to go somewhere, you walk there. If you want to pick something up, you reach out and grab it — albeit by pulling a trigger on a controller rather than physically closing your hand. This makes everything feel easy and natural. When attack drones assault you with lasers in Space Pirate Trainer, you can avoid them by dodging and ducking. When Zombies charge you in Arizona Sunshine, defending yourself is just a matter of raising your arm (and the virtual gun it holds) and shooting. For the first time ever, you don’t need to learn how to manage swing-power meters to play a golf video game — in Cloudlands VR Minigolf you simply swing a club. If you’re a human alive today, you know how to play games in virtual reality. That said, there are still rules to learn. Yes, you can walk around in a real world space, which translates to in-game movement, but that space is limited by reality. How do you walk down a virtual hallway if your real-world couch is in the way? Games like Budget Cuts and The Gallery answer that with teleportation mechanics — moving the player’s physical walking space to a new point in the virtual world. For Budget Cuts , this manifests as an in-game portal gun, where The Gallery uses a simpler (and less narratively explained) fade-cut to the new location. There were abstract experiences too, like the omnipresent canvas of Tilt Brush . This painting program that lets you draw directly on the virtual air around you — but it’s still built upon the rules of a reality the player already understands. It’s not just the visual illusion of the HTC Vive’s headset that made these experiences feel real, it was the act moving, interacting and existing in a virtual world as you do a physical one. For now, that’s an HTC Vive exclusive experience. The Oculus Rift is launching with a focus on a seated experience, although most of the developers at SteamVR’s Developer Showcase did say they planned to port their games to the Rift after Oculus Touch launches later this year. We don’t even know how much the HTC Vive is going to cost , and it’s too early to say which consumer VR headset will reign supreme at the end of the year — but if you do go all in with SteamVR, at least you’ll know that there are a dozen top-tier experiences you can have. Hopefully, this is just the beginning.

Driverless pods to hit the streets of Greenwich

As you stroll past the Royal Observatory in Greenwich and that place where Thor fought in The Dark World , you’ll soon see driverless pods gliding next to you. That’s the plan, anyway. The GATEway project, which has already been experimenting with a self-driving shuttle around the O2, will soon be taking some unusual vehicles onto south London’s streets. They’ll be repurposed Ultra Pods — electric four-wheelers that already operate at Heathrow Airport. Until now they’ve been locked to tracks, but project organiser TRL wants to upgrade them so they can navigate Greenwich independently. Furthermore, the new trial will be used to record exactly how the public reacts to self-driving vehicles. To help with the project, TRL has recruited a handful of experts. These include Westfield Sportscars , a West Midlands company that builds classic automobiles. TRL says it was will act as an “integrator and manufacturer, ” designing and testing the vehicles to ensure they meet road safety standards. Joining them are Oxbotica , a research-based team that was spun out of Oxford University’s Mobile Robotics Group. In short, they’ll be working on the autonomous bits — the software and hardware that deals with mapping, localisation and perception. Finally there’s Heathrow Enterprises, the company that operates the UK’s busiest airport and has plenty of first-hand experience with the dome-shaped pods. The current batch of Ultra Pods have a top speed of 40kph (roughly 25mph) and can carry up to six passengers at once. They’re not the sleekest or most exciting vehicles to look at, but presumably they get the job done at Heathrow and have shown potential as a fully-fledged mode of public transportation. TRL’s expanded consortium is aiming to start the Greenwich trial this summer, before moving on to additional experiments related to autonomous valet parking and automated deliveries.
