Google Veterans Head Off on Their Own to Work on Self-Driving Truck Kits

As reported by The VergeFormer employees of Google, Apple, Tesla, Cruise Automation, and others — 40 people in total — have formed a new San Francisco-based company called Otto with the goal of turning commercial trucks into self-driving freight haulers. Prominent staffers include former Google Maps lead Lior Ron and Anthony Levandowski of Google's self-driving car team.
Rather than building their own trucks, Otto is hoping to make hardware kits for existing truck models that would either be installed by service centers, or possibly at the factory if the company is able to forge manufacturer partnerships. Unlike Google's self-driving car project, Otto would at least initially focus on highway driving, which account for the overwhelming majority of a typical truck route; the human drivers would still handle surface streets, loading, unloading, and the like. Right now, the company is testing with the Volvo VNL 780, but hopes to work with many so-called Class 8 trucks, which are the largest, heaviest trucks on American roads.
A FOCUS ON HIGHWAY DRIVING
If the name Anthony Levandowski sounds familiar, there's a good reason: his work on autonomous driving pre-dates Google's, and he served as the central character in a sprawling profile of the self-driving car project in The New Yorker several years ago. By all appearances, Otto has assembled a deep bench of self-driving expertise at a time when the field's best engineers are being offered enormous amounts of money by Tesla, Apple, and others, perhaps a testament to the pull that Levandowski brings to the table.
Many of Otto's founders have done well for themselves over the years, and it shows: the company is entirely self-funded right now without any external investment. (In the wake of the reported $1 billion Cruise Automation sale to General Motors, I ask Ron if the plan is to get acquired, but he's insistent that they're focused on bringing a product to market.) Even George Hotz's scrappy upstart Comma.ai has recently taken on venture funding from Andreesen Horowitz.otto-02
There's no price or timeline for Otto's commercial product — they say it'll be a "small fraction" of a truck's $100,000 to $300,000 sticker — but that's probably just as well, considering the murky regulatory environment. Levandowski says that apart from contested California regulations requiring steering wheels and pedals, there's nothing on the books banning self-driving cars as long as a human is in the vehicle (which Otto's product would always still require). Still, USDOT, NHTSA, and others are deep in the mix on forming rules around self-driving vehicles with a proposed framework expected later this year. Regardless, the bigger immediate concern for Otto might be rules around how many hours truck drivers can operate their rigs per day; in theory, an Otto-equipped truck might be able to safely operate for many more hours than a human who is always in full control, but Ron says they'll have to work with regulators to prove that out.Otto isn't alone in trying to automate big rigs. Daimler and Volvo Trucks have both demonstrated self-driving systems in recent months, but Levandowski doesn't sound worried about those efforts. "I think the trucking folks are doing a great job, and eventually they would probably solve the problem. But a company that is used to building trucks is not well structured to solve a technology problem," he says. "I'm not trying to dismiss them in any way, I think it's fantastic what they're doing. But I think it's a different time-frame and objectives as to what we're trying to solve and what they're trying to solve."
He also notes that manufacturers' systems would require all-new trucks, unlike Otto, which could be retrofitted. "If you need to replace all of your trucks to get the technology on it, the rate of penetration you'll be able to have is pretty low. Trucks last ten years, a million miles."

DARPA Wants an Underwater GPS System for Seafaring Robots

As reported by WiredWE WOULD BE lost without GPS. The Global Positioning System constellation of satellites started life as a military project, but now enables turn-by-turn directions in the palm of your hand, and confidence that it’s almost impossible to get lost as long as you can see the sky.

Underwater, it’s a different story. GPS doesn’t penetrate the briny deep, so Darpa, the Pentagon’s research arm, wants a system that will keep the robots plumbing the oceans on the map, and it’s asking for proposals from industry. The proposed solution also wins this week’s award for best military acronym: “Posyndon,” for Positioning System for Deep Ocean Navigation.
“What they are trying to do here is revolutionize underwater navigation in a way that is similar for what GPS did for above water,” says Neil Adams, director of defense systems at Draper, the non-profit R&D lab that’s working on an answer.
GPS satellites use very high frequency radio waves (in the L band, between one and two GHz), which can’t penetrate more than a few inches of sea water. To navigate, today’s unmanned underwater vehicles (UUVs), like some submarines, usually rely on dead-reckoning: They start out with an accurate fix on their location, then keep track of where they are, based on how far they’ve travelled, how fast, and in which direction.
That works okay for short trips, but long voyages demand the occasional GPS lock. That means popping to the surface, where military vehicles are vulnerable to detection. And dead reckoning requires expensive, power-hungry inertial measurement units. So, yeah, it’s not an ideal system.
A far better technology for underwater communication is acoustic signals—sound waves—at very low frequencies that travel well over long distances. Instead of satellites transmitting radio frequencies, an underwater GPS system could use a constellation of acoustic transmitters—powered underwater beacons, tethered to the seafloor, sending pings that propagate through the water.
A network of transmitters will allow a UUV to hear signals from several beacons at once and triangulate its position—the way our phones listen for signals from multiple GPS satellites. Now Darpa wants someone to find an appropriate type of acoustic technology, and figure out how many beacons you’d need to give good coverage across an entire ocean basin.
The ocean isn’t the easiest place to work. Posydon’s designers will have to cope with noise pollution, avoiding interference from and with all the other sources of sound in the oceans we make through shipping, drilling, and military exercises.  And they need a decent enough data transfer rate to be able to communicate meaningful information to drone-mounted nav systems. Even subtle changes in water temperature can alter the speed of sound. If the signals sent out from the beacons are going to be reliable enough for navigation, whoever’s running things will need a detailed understanding of how the waves propagate through seawater. Draper plans to start with high-fidelity computer “virtual-ocean” models to figure that out, and back it up with real-world tests.
Adams says any proposal will be cognizant of wildlife concerns. Animals like whales, which sound to communicate over long distances, may suffer from the noises humanity already makes. “We had to submit environmental assessment information, and it’s all well within the acceptable parameters,” he says. The proposal states “Darpa intends that execution of the Posydon program obey all applicable laws and regulations protecting marine life.”
Other researchers looking at this question are interested in bathymetric navigation—the comparison of scans of the ocean floor with known maps. Sonar or LIDaR can be used to do that, but both require a line of sight, and for the vehicle to be actively transmitting. With an acoustic system, the vehicles themselves would be passive listeners, waiting for pings. That level of stealth could be vital in military applications.
Civilians, too, could benefit from a reliable way to navigate underwater. Scientific and commercial research missions using UUVs could be easier and quicker, if the vessel didn’t have to regularly surface. That could happen soon: Darpa wants to see at-sea demonstrations by 2018. If it has its way, there soon won’t be anywhere on the planet where you can still get lost.

NASA Spacecraft Measure Magnetic 'Explosions' That Drive Space Weather

As reported by The VergeFor the first time, NASA spacecraft have measured the strange interactions between the Sun’s and Earth’s magnetic fields that are linked to explosive space weather events high above our planet’s surface. The phenomenon, known as magnetic reconnection, can disrupt satellites and telecommunications systems on our planet. Understanding how it works can potentially help researchers predict such space weather episodes and reduce their destructive side effects.
Magnetic reconnection occurs when the magnetic fields of the Earth and the Sun connect and release intense bursts of energy toward our planet. Scientists have known about these interactions for decades and have linked them to geomagnetic storms, which trigger brilliant aurorae near the Earth's poles. But because such storms can also impact our technology, scientists have been interested in figuring out the underlying physics of magnetic reconnection in space. Today's study, published in the journal Science, confirms a lot of what researchers suspected about the process, but also revealed data the researchers did not expect.
THE MAGNETIC FIELDS OF THE EARTH AND THE SUN CONNECT AND RELEASE INTENSE BURSTS OF ENERGY
Reconnection takes place at the outer edges of the Earth's magnetic field, which is known as the magnetosphere. This field is thought to be generated by liquid iron flowing deep within the Earth’s core. The twisting and turning of this hot metal creates an electrical current, which ultimately produces a charged magnetic field that extends between 40,000 and 370,000 miles around Earth.
The magnetosphere acts like a protective barrier and shields our planet from high-energy solar winds, which would otherwise strip away the gases in our atmosphere and kill life on Earth. The solar winds are created by the Sun's outer atmosphere, which is so heated that it's constantly sending out streams of highly energized, fast-moving particles toward Earth. These charged winds create their own magnetic fields, which clash against our planet's magnetosphere.
Normally, the two magnetic fields oppose each other and move in different directions. But every so often the magnetic field lines switch and connect with each other. That’s called a magnetic reconnection event. "When the two magnetic fields link up, then that allows the solar energy to flow straight into the magnetosphere," said study author Jim Burch, vice president of the space science and engineering at the Southwest Research Institute. "It sets the entire field in motion." The excited particles from the Sun stream into the magnetic field lines of Earth, transferring energy into the magnetosphere.

To study these explosive reconnections directly, NASA launched the Magnetospheric Multiscale, or MMS, mission in March of 2015. The project involved sending four identical spacecraft into orbit around Earth. In space, the probes are situated in a pyramid formation, so that they can study magnetic reconnection in three dimensions.
Instruments onboard the MMS spacecraft were able to precisely detect the movement of electrons during a reconnection event on October 16th, 2015, taking measurements once every 30 milliseconds. This way, the researchers were able to observe how energy was transferred. The data also revealed the behavior of the electrons during magnetic reconnection, showing how fast the particles moved and the directions in which they flowed. The electrons mostly followed the same patterns that researchers predicted.
"This is valuable insight," said Amitava Bhattacharjee, a professor of astrophysical sciences at Princeton University, who was not involved in the study. "It's testing past theory and is certainly bringing to light that certain features were in fact predicted by theory."
LEARNING MORE ABOUT MAGNETIC RECONNECTION MEANS SCIENTISTS CAN POTENTIALLY KNOW WHEN IT IS GOING TO HAPPEN
But during their observations, the researchers also found that the electrons behaved in unexpected ways they had not theorized. That provides more incentive to keep studying magnetic reconnection, the authors write. And by understanding more about the process, scientists can potentially know when magnetic reconnection is going to happen. "If you understand the underlying physics that drives space weather, I expect you can do a better job of predicting storms," said Burch.
That means we could someday know when geomagnetic storms are going to occur, allowing us to take the necessary steps to minimize space weather's effects on our technology.

SpaceX Dragon Departs Space Station, Heads Home With Cargo

As reported by CTV NewsA SpaceX capsule headed back to Earth on Wednesday with precious science samples from NASA's one-year space station resident.
The Dragon left the International Space Station in the morning, bound for an afternoon splashdown in the Pacific, a few hundred miles off the Southern California coast. The station's big robot arm set the Dragon free over Australia. The capsule had been at the station for a month, dropping off supplies as well as an experimental, inflatable room that will pop open in two weeks.
British astronaut Timothy Peake bid farewell to Dragon on behalf of the station's entire six-man crew.
"Dragon spacecraft has served us well, and it's good to see it departing full of science," Peake radioed from 250 miles up. "We wish it a safe recovery back to Planet Earth."
Nearly 4,000 pounds of items fill the Dragon, including blood and urine samples from astronaut Scott Kelly's one-year mission. Kelly returned to Earth in March and has since retired from NASA. Researchers will use the medical specimens to study how the body withstands long journeys in space, in preparation for an eventual mission to Mars in the 2030s.
Also on board: a spacesuit that leaked water into an astronaut's helmet in January, forcing an early end to a spacewalk. Engineers want to examine the suit to see what might have gone wrong.
It is SpaceX's first return trip for NASA in a year. A launch accident last summer grounded the California-based company for months.
SpaceX's Dragon is the only station supply ship that returns to Earth. The other capsules -- Orbital ATK's Cygnus and Russia's Progress -- are filled with trash and burn up on re-entry.
It's the company's eighth return flight from the station since 2012.
The Falcon rocket that launched this Dragon back on April 8 is now in a hangar at Cape Canaveral, Florida -- awaiting another flight.
Rather than getting dumped in the ocean as is customary for launch companies, the Falcon's first-stage booster flipped around after performing its job and flew to a vertical landing on a barge floating in the Atlantic. It was the first successful rocket touchdown at sea. A second booster touched down safely at sea last Friday following a satellite delivery.
SpaceX chief Elon Musk wants to recover and reuse his rockets to drive down costs.

Hyperloop Technologies Gets a New Name Ahead of Propulsion Test

As reported by Engadget: The world of Elon Musk-imagined levitating super trains that fly through tubes is finally a little bit less confusing. Today Hyperloop Technologies changed it's name to Hyperloop One. The new moniker should help reduce any mix ups with competing company Hyperloop Transportation Technologies (HTT). More importantly, the company is ready to publicly demo its propulsion system.

Tomorrow, the company formerly known as Hyperloop Technologies will show off its propulsion system in the Nevada Desert outside of north of Las Vegas. The company says that it can currently hit 400 MPH along an open-air test track but is shooting for 700 MPH within the confines of a vacuum-sealed Hyperloop tube. CTO and Co-founder Brogan BamBrogan said that the company would have a full system, full scale test (a pod racing through a tube) by the end of 2016.
During a presentation in Las Vegas the company also announced Hyperloop One partnerships both in the private and public sector. Probably the most important of those is the state of Nevada. In a statement, Nevada governor Brian Sandoval said, "we believe that Hyperloop One will develop the next mode of transportation while also providing a significant revenue stream and job opportunities for Nevadans."
Because the Hyperloop community loves competition, the company dropped that it's starting the Hyperloop One Global Challenge. It says the event will be an "opportunity for individuals, companies and governments to develop competitive proposals for using the first Hyperloop One solutions on transport corridors in their regions." Proposals are due on September 15, 2016 with the winners announced in March of 2017.

At the event the company also announced that it's taking part in studies to see if routes are feasible in Finland, Norway and between the Los Angeles and Long Beach ports.
But again, the real news is the open-air test of its propulsion system. All the partnerships and competitions in the world won't matter if the Hyperloop One can't get its pods through the tubes. While the chances of confusing it with its rival Hyperloop Transportation Technologies have been reduced thanks to the new name, there's still competition between the two endeavors. Yesterday, HTT announced that it will use the government-developed Inductrack levitation system. It will be partnering with Lawrence Livermore National Laboratory to bring the passive magnetic system to its pods.

If successful, Hyperloop One is looking beyond passengers to cargo. BamBrogan even hypothesized the potential of moving an entire port offshore and using underwater Hyperloop tracks and pods to move goods from ships to the land. This would expand the company's idea to put tubes underwater along the shoreline.
Hyperloop One has built an approximately half-mile open-air test track. If all goes according to plan, an approximately 10-foot sled on tracks will zip forward at 116 miles an hour, and crash into a pile of sand, since the company hasn’t yet built brakes for the contraption.

Nikola Motor Company Enters Electric Vehicle Market with 2,000hp Truck

As reported by Tech DailyA new electric vehicle company breaks cover led by Trevor Milton. The Nikola Motor Company has come out of hiding announced the Nikola One class 8 electric semi-Truck and the Nikola Zero 4×4 electric UTV.

The Salt Lake City based electric vehicle startup has been created by Trevor Milton, who has been CEO of dHybrid Systems, a natural gas storage technology company that got acquired by Worthington Industries in 2014.
The Nikola One Truck has 2,000 hp and a 1,200 miles range. It carries 320kWh battery that power the 6×6 electric drive. The Nikola One has regenerative braking and a turbine that charges the batteries.
The Nikola Zero UTV has a 100 to 150 miles range and 520hp. The all-wheel drive UTV has a 50kWh battery and accelerates to 60mph in 3s. The Nikola Motor Company takes a page out of Tesla Motors playbook and offers reservations of their vehicles which are in a prototype stage. The Nikola One Truck can be reserved for $1,500 and the UTV for $750.
There is no word yet on when Nikola Motor Company will be able to actually deliver any of their planned vehicles. Prototypes are supposed to be shown later this year. Nikola Motor Company is of course named after the famous inventor and electrical engineer Nikola Tesla. If the name brings good fortunes remains to be seen.
The Nikola Motor Company released many technical details about their planned electric vehicle that look impressive. At least we know what electric vehicle this company is working on, in contrast to secretive Apple, which is also supposed to build an electric vehicle under the project Titan.

Personal Aircraft Aiming to Take Off From Your Home

As reported by Phys.OrgA start-up company hosted in an ESA business incubator is developing the world's first vertical takeoff and landing aircraft for personal use. The electric two-seater will open the door to a new class of simpler, quieter and environmentally friendly planes available from 2018.

"Our goal is to develop an aircraft for use in everyday life," explains Daniel Wiegand, CEO and one of the company's four founders.
"We are going for a plane that can take off and land vertically and does not need the complex and expensive infrastructure of an airport.
"To reduce noise and pollution, we are using electric engines so it can also be used close to urban areas."
Founded in February 2015 by four engineers and doctoral students from the Technical University of Munich in Germany, Lilium has already proved the concept with several scale, 25 kg prototypes and is now developing its first ultralight  and landing aircraft.
Simpler and easier air transportation
Today, general public aviation offers fixed-wing aircraft and helicopters. Conventional aircraft are efficient, fast and available in many sizes but require airports often 20–50 km from city centres because of their space-hungry runways and the high noise levels.
Airports are expensive bottlenecks for transportation. This is especially so for short-haul flights, where travel time to and from airports can easily double the duration of a trip. This is not a problem for helicopters, which can take off almost anywhere and are therefore often used for short shuttle flights and special applications.

However, helicopters are very noisy and difficult to fly – which requires expensive licences. They also have no backup in case of rotor failure, making them expensive to build and maintain.
The Lilium vehicle combines the benefits of helicopters and fixed-wing aircraft while avoiding their drawbacks. While initially restricted to airfields, the goal is for it to take off vertically from almost anywhere – even from back gardens – it needs only an open flat area of about 15x15 m.
Although taking off and landing like a helicopter, by swivelling its engines it also functions as a very efficient aircraft that can travel at up to 400 km/h.

Entirely electric, the plane is much quieter during takeoff than helicopters thanks to its ducted fan engines. Its batteries, engines and controllers are redundant, making it a much safer design than conventional helicopters.
The plane is classed as a Light Sport Aircraft for two occupants, with the pilot's licence requiring 20 hours' minimum training – almost like taking a driving licence.
It is intended for recreational flying during daylight, in good weather conditions and in uncongested airspace up to 3 km altitude.

Using computer control for vertical takeoff and landing is essential for a vehicle targeted at the consumer market for personal transportation.
Powered from a simple wall plug
Highly efficient in its cruising mode, the vehicle will have a range of 500 km. It features a touchscreen and fly-by-wire joystick controls, retractable landing gear, wing doors, large storage, panoramic windows, and a battery that can be recharged from any wall plug.

Satnav is crucial to the high degree of automation and wind compensation during takeoff and landing.
The company is hosted at ESA's Business Incubation Centre in Bavaria, which offers a workshop for developing and building the prototypes and final plane.
Located directly next to the Special Airport Oberpfaffenhofen, the company has direct access to test fields and an inspiring aviation-friendly environment.

"The half-size prototype is already flying and now under test. The full-size unmanned prototype is planned for this summer," says Thorsten Rudolph, CEO of AZO, which runs the incubator, one of many in ESA's Technology Transfer Programme throughout Europe.
"We are helping the Lilium team to turn their idea into a viable business. They are the aircraft experts, and we provide the expertise on how to make a business out of their dream."
Supported by a venture capital investor, the company is planning its first manned experimental flight in 2017 and rollout of the completed vehicle for licensing by 2018, ready for initial production to begin meeting orders. Serial production will follow later.
The retail cost will be far less than similar-sized aircraft of today and with much lower running costs.
"In the longer term, our target is to build an  that not only the super-rich can afford, and that can make private air transportation possible for a much wider number of people," adds Daniel.
"With the concept of taking off and landing almost everywhere, we could see that one day our plane will be used for quick and daily transportation almost like a car today."
