University of Michigan opens up its M-Air UAV testing facility to students

Companies and students who want to test an autonomous vehicle at the University of Michigan have the excellent Mcity simulated urban environment. But if you wanted to test a drone, your options were extremely limited — think “at night in a deserted lecture hall.” Not anymore: the school has just opened its M-Air facility, essentially a giant netted playground for UAVs and their humans.

It may not look like much to the untrained eye, and certainly enclosing a space with a net is considerably less labor-intensive than building an entire fake town. But the benefits are undeniable.

Excited students at a school like U-M must frequently come up with ideas for drone control systems, autonomous delivery mechanisms, new stabilization algorithms and so on. Testing them isn’t nearly as simple, though: finding a safe, controlled space and time to do it, getting the necessary approvals and, of course, containing the fallout if anything goes wrong — tasks like these could easily overwhelm a few undergrads.

M-Air serves as a collective space that’s easy to access but built from the ground up (or rather, the air down) for safe and easy UAV testing. It’s 80 by 120 feet and five stories tall, with a covered area that can hold 25 people. There are lights and power, of course, and because it’s fully enclosed it technically counts as “indoor” testing, which is much easier to get approval for. For outdoor tests you need special authorization to ensure you won’t be messing with nearby flight paths.

We can test our system as much as we want without fear of it breaking, without fear of hurting other people,” said grad student Matthew Romano in a U-M video. “It really lets us push the boundaries and allows us to really move quickly on iterating and developing the system and testing our algorithms.”

And because it’s outside, students can even test in the lovely Michigan weather.

“With this facility, we can pursue aggressive educational and research flight projects that involve high risk of fly-away or loss-of-control — and in realistic wind, lighting and sensor conditions,” said U-M aerospace engineering professor Ella Atkins.

I feel for the neighbors, though. That buzzing is going to get annoying.

FCC approves SpaceX plan for 4,425-satellite broadband network

SpaceX has a green light from the FCC to launch a network of thousands of satellites blanketing the globe with broadband. And you won’t have too long to wait — on a cosmic scale, anyway. Part of the agreement is that SpaceX launch half of its proposed satellites within six years.

The approval of SpaceX’s application was not seriously in doubt after last month’s memo from FCC Chairman Ajit Pai, who was excited at the prospect of the first U.S.-based company being authorized to launch a constellation like this.

“I have asked my colleagues to join me in supporting this application and moving to unleash the power of satellite constellations to provide high-speed Internet to rural Americans,” he wrote at the time. He really is pushing that “digital divide” thing. Not that Elon Musk disagrees:

SpaceX COO Gwynne Shotwell echoed the sentiment in a statement provided to TechCrunch:

We appreciate the FCC’s thorough review and approval of SpaceX’s constellation license. Although we still have much to do with this complex undertaking, this is an important step toward SpaceX building a next-generation satellite network that can link the globe with reliable and affordable broadband service, especially reaching those who are not yet connected.

The proposed service, which will be called Starlink, was opposed by several existing satellite operators like OneWeb and Spire. They’re rightly concerned that another operator in space — especially one that wants to launch thousands of satellites — will crowd both spectrum and orbit.

Illustration of SpaceX satellite coverage from the FCC application

OneWeb, for example, said that SpaceX satellites shouldn’t be allowed to be deployed within 125 kilometers of altitude of its own. You do want to avoid interference, but really, it’s too much to ask for a 150-mile buffer zone around your gear.

One objection that did carry water, however, was the request for an extensive orbital debris mitigation plan.

The unprecedented number of satellites proposed by SpaceX and the other [non-geostationary orbit fixed-satellite service] systems in this processing round will necessitate a further assessment of the appropriate reliability standards of these spacecraft, as well as the reliability of these systems’ methods for deorbiting the spacecraft.

So SpaceX will have to provide more studies on this by the time it finalizes its designs and starts launching.

And that will have to be fairly soon. To move things along, the FCC requires SpaceX to get underway in a hurry or else, presumably, it will have to be reauthorized:

SpaceX must launch 50 percent of the maximum number of proposed space stations, place them in the assigned orbits, and operate them in accordance with the station authorization no later than March 29, 2024.

The company has already launched test versions of the satellites, but the full constellation will need to go out more than two at a time. SpaceX eventually plans to launch 12,000 of the things, but this authorization is for the high-altitude group of 4,425; a separate authorization is necessary for the remaining number, since they’ll be operating at a different altitude and radio frequency.

The Falcon 9 carrying SpaceX’s test Starlink satellites launches on February 22

Commissioner Rosenworcel, in a separate statement, also called for a general revisiting of regulations around commercial space.

“This rush to develop new space opportunities requires new rules,” she writes. “Despite the revolutionary activity in our atmosphere, the regulatory frameworks we rely on to shape these efforts are dated. Across the board, we need to prepare for the proliferation of satellites in our higher altitudes. In short, we have work to do.”

Apple releases iOS 11.3 with new Animojis

Apple just released an iOS update for your iPhone and iPad. 11.3 introduces a ton of bug fixes but also a bunch of new features. If you forgot about Animjois, today is your lucky day as Apple is adding four new Animojis — a dragon, a bear, a lion and a skull.

But that’s not all. Apple already shared a preview of iOS 11.3 a couple of months ago. There’s a big ARKit update to ARKit 1.5. It can recognize more objects and surfaces.

And iOS 11.3 is also the battery update we’ve all been waiting for. There’s some new info in the settings about the status of your battery. It tells you the overall capacity and if it’s time to change your battery.

You can also choose to disable Apple’s controversial decision to throttle performance with old batteries. Apple says it’s a beta feature for now.

Apple is also introducing a new feature in the Health app. You can now centralize all your health records in the app. It’s only limited to a handful of clinics for now.

Apple is adding customer support conversations to Messages. You can initiate a conversation with a business to order something, book a table and more. Discover, Hilton, Lowe’s and Wells Fargo are already on board. Health Records and Business Chats are only available in the U.S. as a beta for now.

You’ll also see a new privacy icon across the operating system. A new website to export all your data is coming in May as well. Apple needs to add those features to comply with GDPR.

Finally, Apple Music is getting a new video clips section, the App Store Updates tab now shows you the size of each update and more tiny little things. And if you care about security, it’s always a good thing to update to the latest version of iOS. Unfortunately, iOS 11.3 still doesn’t include iMessage in iCloud.

Back up your iPhone or iPad to iCloud or your computer using iTunes before updating. You can then head over to the Settings app, then ‘General’, then ‘Software Update’. macOS, watchOS and tvOS updates are also available today.

Festo’s latest bio-inspired creations are a robo-bat and rolling robo-spider

Festo’s flashy biomimetic robots are more or less glorified tech demos, but that doesn’t mean they aren’t cool. The engineering is still something to behold, although these robot critters likely won’t be doing any serious work. Its latest units move in imitation of two unusual animals: a tumbling spider and a flying fox (think big bat).

The BionicWheelBot, when walking, isn’t anything we haven’t seen before: hexapodal locomotion has been achieved by countless roboticists — one recent project even attempted to capture the spontaneity of an insect’s gait.

But its next trick is new, at least if you haven’t watched the Star Wars prequels. It uses the legs on each side to form a wheel and propels itself with the last pair. Useful for getting downhill or blowing in the wind, as some spiders and insects in fact do.

It looks as if it can get going quite fast, and although it seems to me it would be in a fix if knocked over, it had no problem dropping off the end of the table and rolling on in the Festo video.

The other robo-critter is the BionicFlyingFox, modeled on the enormous fruit bats bearing that name. Like all flying creatures there is a great emphasis on lightness and simplicity, allowing this robot (like its distant forebear, Festo’s bird) to flap around realistically and stay aloft for a time.

In imitation of the strong but light and flexible membrane that forms flying mammals’ wings, the Festo bot uses a modified elastane material (sort of a super-Spandex) that’s airtight and won’t crease or rip.

If you’re lucky, you might see one of these majestic robeasts demonstrated at a robotics conference one day.

We go butt-on with the Blix Komfort Prima electric bike

Blix is a new European ebike brand that melds high style, faux leather, and a really nice electric drive train to create a $2,500 ebike that might be too pricey for some but hits most of the buttons when it comes to a fully augmented bike ride. The bike, called the Blix Komfort Prima, runs about 60 miles per charge on Eco mode and essentially adds small boost to your regular pedaling. It includes disc brakes as well as front and rear lights and when you amp it up to High power mode you can really fly at about 20mph.

I rode this bike around Brooklyn including on a 10 mile trek on the city streets and the ride was surprisingly pleasant. The Komfort Prima uses the Shimano Step system to add a boost to your regular peddling, thereby allowing you to take hills with ease and get a little help on straightaways. In fact, the Step system is almost undetectable in Eco mode but it still goes a long way to making your ride more comfortable.

I like the styling of the bike and the high quality accessories. I also like the Step’s removable battery pack – a huge improvement over previous ebikes I’ve ridden. What I don’t love is the price but at $2,500 for a slick, smooth ride you’re on par with similar offerings from Yamaha and Raleigh. The space is changing quickly and it’s nice to see smaller players introducing high style, quality bikes at prices on par with bigger competitors.

Build your own PC inside the PC you built with PC Building Simulator

Considering we’ve got simulators for everything from driving a junker (x2) to moving into a neighborhood with a bunch of hot dads in it, I suppose it was only a matter of time until someone made a game where you assemble your own PC. It’s called PC Building Simulator, as you might guess, and it looks fabulous.

I’ve built all my PCs over the years, including my current one, which I really should have waited on, since the early Skylake mobos were apparently trash. I’m sure we can line up the screw holes better than that, MSI!

What was I talking about? Oh yes, the simulator. This is no joke game: it uses real, licensed parts from major manufacturers, which are (or will be) simulated down to their power draws, pins, draw counts and so on. So if you pick a power supply without enough molex connectors to handle your SLI rig and PCIe solid state system drive (or whatever), it won’t start. Or if you try to close the ultra-slim case with an 8-inch-tall heatsink on your overclocked CPU, it’ll just clank. (Some of these features are still in development.)

Add LEDs inside the case, replace the side panel with acrylic (no!), try out a few cooling solutions… the possibilities are endless. Especially since manufacturers like Corsair, AMD and so on seem hot to add perfectly modeled virtual versions of their components to the selection.

There’s even a “game” aspect where you can start your own PC repair business — someone sends you a machine that won’t boot, or shuts down randomly, and you get to figure out why that is. Run a virus scan, reseat the RAM, all that. Damn, this sounds just like my actual life.

Seriously though, this is great — it might help more people get over the idea that building a PC is difficult. I mean, it is, but at least here you can go through the motions so it isn’t a total mystery when you give it a shot.

The best part is that this game is made by a teenager who put together the original as a lark (it’s free on itch.io) and attracted so much attention that it’s been blown up into a full-blown game. Well, an Early Access title, anyway.

Inquiry finds FBI sued Apple to unlock phone without considering all options

The Office of the Inspector General has issued its report on the circumstances surrounding the FBI’s 2016 lawsuit attempting to force Apple to unlock an iPhone as part of a criminal investigation. While it stops short of saying the FBI was untruthful in its justification of going to court, the report is unsparing of the bureaucracy and clashing political motives that ultimately undermined that justification.

The official narrative, briefly summarized, is that the FBI wanted to get into a locked iPhone allegedly used in the San Bernardino attack in late 2015. Then-director Comey explained on February 9 that the Bureau did not have the capability to unlock the phone, and that as Apple was refusing to help voluntarily, a lawsuit would be filed compelling it to assist.

But then, a month later, a miracle occurred: a third-party had come forward with a working method to unlock the phone and the lawsuit would not be necessary after all.

Though this mooted the court proceedings, which were dropped, it only delayed the inevitable and escalating battle between tech and law enforcement — specifically the “going dark” problem of pervasive encryption. Privacy advocates saw the suit as a transparent (but abortive) attempt to set a precedent greatly expanding the extent to which tech companies would be required to help law enforcement. Apple of course fought tooth and nail.

In 2016 the OIG was contacted by Amy Hess, a former FBI Executive Assistant Director, who basically said that the process wasn’t nearly so clean as the Bureau made it out to be. In the course of its inquiries the Inspector General did find that to be the case, though although the FBI’s claims were not technically inaccurate or misleading, they also proved simply to be incorrect — and it is implied that they may have been allowed to be incorrect in order to further the “going dark” narrative.

The full report is quite readable (if you can mentally juggle the numerous acronyms), but the findings are essentially as follows.

Although Comey stated on February 9 that the FBI did not have the capability to unlock the phone and would seek legal remedy, the inquiry found that the Bureau had not exhausted all the avenues available to it, including some rather obvious ones.

Comey at a hearing in 2017

For instance, one senior engineer was tasked with asking trusted vendors if they had anything that could help — two days after Comey already said the FBI had no options left. Not only that, but there was official friction over whether classified tools generally reserved for national security purposes should be considered for this lesser, though obviously serious, criminal case.

In the first case, it turned out that yes, a vendor did have a solution “90 percent” done, and was happy to finish it up over the next month. How could the director have said that the FBI didn’t have the resources to do this, when it had not even asked its usual outside sources for help?

In the second, it’s still unclear whether there in fact exist classified tools that could have been brought to bear on the device in question. Testimony is conflicting on this point, with some officials saying that there was a “line in the sand” drawn between classified and unclassified tools, and another saying it was just a matter of preference. Regardless, those involved were less than forthcoming even within the Bureau, and even internal leadership was left wondering if there were solutions they hadn’t considered.

Hess, who brought the initial complaint to the OIG, was primarily concerned not that there was confusion in the ranks — it’s a huge organization and communication can be difficult — but that the search for a solution was deliberately allowed to fail in order that the case could act as a precedent advantageous to the FBI and other law enforcement agencies. Comey was known to be very concerned with the “going dark” issue and would likely have pursued such a case with vigor.

So the court case, Hess implied, was the real goal, and the meetings early in 2016 were formalities, nothing more than a paper trail to back up Comey’s statements. When a solution was actually found, because an engineer had taken initiative to ask around, officials hoping for a win in court were dismayed:

She became concerned that the CEAU Chief did not seem to want to find a technical solution, and that perhaps he knew of a solution but remained silent in order to pursue his own agenda of obtaining a favorable court ruling against Apple. According to EAD Hess, the problem with the Farook iPhone encryption was the “poster child” case for the Going Dark challenge.

The CEAU Chief told the OIG that, after the outside vendor came forward, he became frustrated that the case against Apple could no longer go forward, and he vented his frustration to the ROU Chief. He acknowledged that during this conversation between the two, he expressed disappointment that the ROU Chief had engaged an outside vendor to assist with the Farook iPhone, asking the ROU Chief, “Why did you do that for?”

While this doesn’t really imply a pattern of deception, it does suggest a willingness and ability on the part of FBI leadership to manipulate the situation to its advantage. A judge saying the likes of Apple must do everything possible to unlock an iPhone, and all forward ramifications of that, would be a tremendous coup for the Bureau and a major blow to user privacy.

The OIG ultimately recommends that the FBI “improve communication and coordination” so that this type of thing doesn’t happen (and it is reportedly doing so). Ironically, if the FBI had communicated to itself a bit better, the court case likely would have continued under pretenses that only its own leadership would know were false.

Nvidia stuns by driving a car in real life through virtual reality

Today at Nvidia’s GTC conference the company unveiled a wild technology demo and it’s straight out of Black Panther. Simply put, a driver using virtual reality was remotely controlling a car in real life.

“He’s not with us,” Jensen Huang, CEO of Nvidia, said pointing the driver on the stage. “He’s looking at this virtual world through live video.”

The driver was sitting on the stage of the convention center wearing an HTC Vive and seated in a cockpit-like car with a steering wheel. Using Nvidia’s Holodeck software, a car was loaded (the same Lexus used in Black Panther). Then, a video feed appeared showing a Ford Fusion behind the convention center.

The demo at the show was basic but worked. The driver in VR had seemingly complete control over the vehicle and managed to drive it, live but slowly, around a private lot. He navigated around a van, drove a few hundred feet and parked the car.

[gallery ids="1613009,1613007,1613005,1613004,1613003,1613001,1613000"]

The car was empty the whole time.

Nvidia didn’t detail any of the platforms running the systems nor did he announced availability. The demo was just a proof of concept. Jensen even exclaimed “we don’t know what to call it. What do we call it?”

Self-driving technology is a massive market for Nvidia, and the company is a leader in supplying technology. And demos like this are a great way to keep the attention on the company’s capabilities.
