London's Iconic Black Cab Goes All Electric

As reported by GizMagThe London Taxi Company (LTC) has unveiled a new version of the Black Cab that famously operates in London, UK. The TX5 is said to retain the spirit of past models and focus on driver and passenger comfort. Reflecting the move toward a low-carbon economy, it will be electric powered.

The predecessor of the new London taxi, the TX4, was launched in 2007 and, although electric versions of it were developed, models on the streets invariably had a conventional diesel engine under the bonnet.
According to LTC, all of the 2,000 components for the TX5 have been designed from the ground up. It has a new lightweight aluminum body structure and composite paneling, rear-hinged doors to improve passenger access and space for a forward-facing wheelchair. It also has a panoramic glass roof.
The cab can accommodate six passengers and provides more legroom for the driver. It is equipped with Wi-Fi connectivity and mobile device charging points for both the driver and passengers.
The TX5 was designed by Brits Peter Horbury and David Ancona at Geely’s design center in Barcelona. They were supported by over 200 engineers and designers in the UK. Hornbury says they were acutely aware of the responsibility that came with designing a new model of such a recognizable and iconic vehicle.
"We wanted to retain those aspects that make the London taxi what it is and what it stands for, while ensuring that the new design reflects everything that a 21st century vehicle needs to be," said Horbury. "We have sought to build on existing features such as the headlights, grille and strong roof lines. But we have also made sure that the new vehicle significantly builds on space and comfort levels for both passengers and drivers."
More detailed specifications about the TX5 have yet to be announced. It is due to be launched in the UK at the end of 2017 and across international markets in 2018.

Battelle’s DroneDefender Anti-Drone Beam Gun Grounds UAVs


As reported by GizMagThere's recently been a run of new anti-drone systems introduced to deal with potential threats from UAVs, but these have been on the large and expensive side. To provide an affordable alternatives to plug the gap between shotguns and truck-mounted systems, national security research and development firm Battelle is introducing DroneDefender. Billed as the first portable, accurate, rapid-to-use UAV counter-weapon, it's a rifle-like raygun device that uses a radio beam to jam drone control systems and stop them in midair.
Most UAVs in service today are relatively harmless, but their growing numbers increases the risk that they will be used maliciously or carelessly. Recent systems for dealing with rogue drones have taken one of two approaches. One type destroys UAVs by shooting them down with special anti-aircraft guns, which has the obvious limitation that such weapons can't be used in many areas for legal or safety reasons. The other type uses large-scale jamming systems that fire radio beams to interfere with the drone's controls, but many of these, like the anti-aircraft guns, are very large, expensive, and not at all suitable for dealing with minor problems at small installations or following VIPs and other targets on the move.
Battelle's DroneDefender is designed as a point-and-shoot system that looks like an elaborate shoulder raygun with two antennae, a software-defined radio, and jamming circuitry. It works by firing a radio beam in a 30° cone that jams the control and GPS navigation frequencies to disable drones at distances of up to 400 m (1,300 ft). Battlle says that the system not only freezes the UAV, but also stops all outside control commands, including radio detonation signals.
The DroneDefender places a heavy emphasis on speed and portability. It weighs under 10 lb (4.5 kg), can cold-start in under a tenth of a second, and operates continuously for up to five hours with optional battery packs. It can be carried or fixed on a Picatinny rail mount and comes in hardened versions for forward deployment in hazardous areas.
Battelle says that the DroneDefender requires no special training to use, has already been tested against a DJI Phantom drone target, and has shown a consistent response in field conditions.
Because, US FAA regulations prohibited an actual demonstration, the video below shows a simulation of the DroneDefender in use.

Bulldozers Guided by Drones are Helping Ease Japan's Labor Shortage

As reported by The VergeKomatsu is the world’s second largest construction company, a venerable Japanese brand with 94 years of history that sells forklifts and bulldozers to customers around the globe. But in its home country, Komatsu has been struggling with an aging population, a trend that has left few young workers available to operate its machines.
As Japan ramps up new construction in preparation for hosting the 2020 Olympics, experts believe it will face a serious obstacle. "The labor shortage in the construction industry could reach a crisis level in the next few years," Martin Schulz, an economist at Fujitsu Research Institute in Tokyo, told Bloomberg.
To get around this problem, Komatsu has begun creating a new service it calls Smart Construction. A team of robotic vehicles scoops rock and pushes dirt without a human behind the wheel. They are guided in their work by a fleet of drones, which map the area in three dimensions and update the data in real time to track how the massive volumes of soil and cement are moving around the site.skycatch gif 1 The drones are built by an American startup, Skycatch, and today it revealed that Komatsu is one of the principal investors in a new $25 million round of funding that the company plans on using for global expansion and R&D. The partnership will power an entirely new line of business for Komatsu: Instead of selling construction equipment to its customers, it can lease them out for a job, and use a staff of remote operators and autonomous vehicles to complete the work. One or two lightly trained humans are still required on site to take control if something goes wrong.
Before switching to drones, Komatsu had been experimenting with autonomous dump trucks, bulldozers, and excavators, but they lacked the ability to see and understand the environment around them with enough precision to be useful on their own. Komatsu would use teams of human surveyors to create extremely detailed maps of the job site, a process that left a lot of room for improvement. "Because the terrain survey could not be conducted with high accuracy, what results in many sites is a 20 to 30 percent margin of error in soil volume after the construction is complete," says Chikashi Shike, an executive with Komatsu’s Smart Construction division.skycatch drone gif 2With Skycatch drones, Komatsu says it has dramatically reduced that margin of error while dramatically cutting the time it takes to complete a sitemap. "With the former, traditional method, it takes about two weeks, on average, to survey a certain piece of land," says Kenishi Nishihara, a project manager with the Smart Construction division. "Meanwhile with Skycatch it can be completely down within one day, or even 30 minutes."
Skycatch is based in Silicon Valley, but has decided to focus its business almost entirely on Japan. "The regulations in the United States make it difficult to operate in a fully autonomous manner, and so that makes it tough to get the full value out of drones," says Skycatch CEO Christian Sanz. Of course, not every country is facing such dramatic labor shortages. "In Japan, there is a clear recognition, and appreciation, of the work these drones can do," says Sanz. "In other places, people are still cautious about collaborating with robots to do jobs that were typically handled by humans."

Unmanned System for Navy Boats Takes to the Water

As reported by GizMagIn the waters near Portsmouth Naval Base, a small black boat recently roared about with no one at the controls. It hadn't run amok after the pilot fell overboard, but was instead a demonstration of a new robotic system developed by ASV and BAE Systems. The technology package can be retrofitted to the Rigid Inflatable Boats (RIB) used by the Royal Navy (RN) to turn them into high-speed, autonomous, unmanned reconnaissance and surveillance platforms.


Even in an age of aircraft carriers and satellites, small boats are still vital Naval assets. The manned Pacific 24 RIB used by the RN aboard its Type 23 Frigates and Type 45 Destroyers will also be used by the Queen Elizabeth Class aircraft carriers now under construction. They act as the eyes and ears of their parent ship by going where she cannot. Unfortunately, it's often dangerous work and the Royal Navy and other services are rather keen to find ways to send in the boats while the sailors stay home.
This is where the new autonomous demonstrator comes in. It's designed to not only to take the sailor out of the equation, but also to be retrofitted to the Pacific 24s already in service.
The unmanned system and its software were developed by Portchester, UK-based ASV Unmanned Marine Systems with BAE Systems helping to integrate the technology in the demonstrator. BAE Systems says the robotic boat can reach speeds of over 38 knots (44 mph, 70 km/h), and operate for up to 12 hours and up to 40 km (25 mi) from its ship. It can be controlled by either a conventional human pilot or a hand-held remote controller, or run completely autonomously.
For navigation and reconnaissance, the system uses a sensor suite that includes navigation radar, a 360-degree panoramic infrared camera array, and a laser range finder. These are backed up by complex algorithms developed by ASV.
"The algorithms we’re developing with BAE Systems allow the boat to perform complex missions and navigate through waters avoiding collisions," says Dan Hook, Managing Director for ASV. "This gives it the flexibility and sophistication to operate in a number of different tactical roles, whether it’s patrolling areas of interest, providing surveillance and reconnaissance ahead of manned missions, or protecting larger ships in the fleet."
According to BAE Systems, the demonstration opens the way to the next phase of development, which will see the creation of the sensor suite and it's integration into the parent ship combat management system.
"This technology delivers an extremely robust and fast-moving unmanned boat that is able to perform a number of surveillance and reconnaissance roles, even when operating at high speed or in choppy water," says Les Gregory, Product and Training Services Director at BAE Systems. "BAE Systems has a wealth of experience in the development and integration of unmanned systems. The successful demonstration highlights the enhanced capability this technology offers. While other programs are primarily designed for larger, slower boats to tackle mine counter-measure scenarios, this system provides an extremely maneuverable multi-role vessel."
The video below introduces the new autonomous system.

Stanford Turns a DeLorean Into a Drifting, Driverless Car

As reported by EngadgetThis isn't from some weird movie franchise mashup entitled Back to the Future IV: Stanford Drift. No, Stanford's Revs Center simply decided to experiment on an old DeLorean, giving it the ability to fly drift all on its own. The car, which the team decided to called MARTY (Multiple Actuator Research Test bed for Yaw control) as an homage to B2F, was heavily modified and modernized. DeLoreans are old cars, and they found that it had severe limitations: for instance, it was understeering, so they had to equip it with a power steering motor and rack.

As for why they wanted to design a driverless car that's good at drifting in the first place, well, Revs Center director Chris Gerdes told Wired: "We think automated vehicles should be able to execute any maneuver within the physical limits of the vehicle to get out of harm's way." In other words, they believe autonomous cars should be able to drift if it means saving the passenger's life. If the idea of a drifting DeLorean sounds weird, just watch the team do some perfectly executed donuts in the video below.

NASA Launches Website Hosting Stunning, Regularly Updated Earth Imagery

As reported by GizMag: NASA has launched a new website allowing the public to view images snapped by its Deep Space Climate Observatory (DSCOVR) satellite. The service will provide multiple shots of stunning Earth imagery seven days a week, mere hours after capture.

DSCOVR is operated through a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the US Air Force, with a mission to monitor space weather emanating from the Sun, and serve as a form of early warning system for potentially harmful events.
DSCOVR will also make use of its position relative to Earth to keep track of daily variations in our planet's atmospheric and surface health. The images uploaded to the website are captured by the probe's Earth Polychromatic Imaging Camera (EPIC), an advanced camera with an effective resolution ranging from 6.2 - 9.4 miles (10 - 15 km).
The orbiter is able to regularly capture Earth's disk fully bathed in sunlight thanks to its presence at what is known as the L1 Lagrange point, a special orbital position about one million miles out from our planet that places the probe in a near constant position suspended between the Earth and Sun.
Images featured on the website are captured roughly 12 – 36 hours prior to release, and feature a simple graphic to the top left of the page informing users of the relative positions and distances of the DSCOVR satellite and our Sun. The page also displays a globe highlighting the landmasses that are in view.
Archived images will be accessible by searching for the subject's capture date and the continents displayed in the image.
With the website operational, NASA will provide a regular stream of images to the public at a rate of at least a dozen per day, representing the most comprehensive and unified full-Earth viewing service ever launched.

Open Garden's 'FireChat' in Tahiti to Create a Mesh Network that Eliminates the Need for Wireless Carriers

As reported by Venture BeatIf you’ve dreamed of a mobile world where you don’t need AT&T or Verizon Wireless, then you might consider a vacation to Tahiti.

Open Garden, makers of the mobile app FireChat, have announced a partnership with local leaders that will turn the French Polynesian island of Tahiti into a post-carrier paradise. FireChat is a peer-to-peer wireless networking app that relays calls and messages through phones by creating a mesh network that doesn’t require the traditional cell network to send messages.
Under the terms of the new project, residents of the island will be able to communicate with each other without needing a data plan or other kind of connection to the Internet.
“We are very grateful for the opportunity to work on the Smart Tahiti project spearheaded by STN and with the City of Arue,” Christophe Daligault, chief marketing officer of Open Garden, said in a statement. “Our technology alleviates the dependency on traditional infrastructure and enables communities to create their own free communication networks that are disaster-proof.”
The hope is that the new network will help more people get connected to each other. But it will also provide a backup network in the event of some crisis that knocks out the island’s infrastructure.
Founded more than four years ago, Open Garden created FireChat to offer a different way for users to construct wireless networks. Users download the app, which then finds other nearby FireChat users via the phone’s Wi-Fi and Bluetooth. Fully encrypted private and public messages and pictures can be sent via this mesh networking, hopping from one FireChat user to another until they’re delivered to the intended recipient.
This ability to connect without using telecom carriers has made the app incredibly popular among people who want greater privacy. During last year’s protests in Hong Kong, the app was downloaded hundreds of thousands of times and was credited with creating a communication system that local authorities couldn’t monitor or block.
A few months later, Open Garden raised $10.8 million to continue expanding the reach of FireChat. The app has become popular at large concerts and festivals. And the company also hopes to use it to bring networks to people in regions with little or no wireless network access.
This past summer, the app became popular with those attending the Burning Man Festival in Nevada.
