Sheer cliff faces present a traversal challenge for most wheeled robots on the market, but researchers at the University of Tokyo say they've developed a two-robot framework that works pretty reliably in their testing. In a newly published paper on the preprint server Arxiv.org "[We] propose a novel cooperative system for an Unmanned Aerial Vehicle (UAV) and an Unmanned Ground Vehicle (UGV) which utilizes the UAV not only as a flying sensor but also as a tether attachment device," the authors of the paper explain. "[It enhances] the poor traversability of the UGV by not only providing a wider range of scanning and mapping from the air, but also by allowing the UGV to climb steep terrains with the winding of the tether." The UGV is permanently attached via mechanized winch and cable to the UAV, a custom-made quadcopter with an Nvidia Jetson TX2 chipset, a flight controller, and a raft of sensors including a modular fisheye camera, time-of-flight sensor, inertial measurement unit (IMU), and laser sensor.

China is poised to overtake the United States in artificial intelligence with a surge in academic research on the key technology, an analysis published Wednesday showed. The analysis by the Allen Institute for Artificial Intelligence showed China has already surpassed the US in published papers on AI -- although many of these were considered "medium-quality" or "low-quality." But the researchers said China is likely to top the US in the most-cited 50 percent of papers this year, the most-cited 10 percent of papers next year, and in the top one percent by 2025. The findings highlight concerns in Washington and Silicon Valley that China is racing ahead of the US in key areas of technology such as autonomous vehicles, virtual reality and fifth-generation wireless networks. Allen Institute researchers Field Cady and Oren Etzioni said the surge in AI investment in China began more than a decade ago, well before the 2017 announcement by Beijing that it planned to become the world leader in the sector by 2030.

Artificial intelligence may soon get a power boost from quantum computing. Researchers have shown that it's possible to sort and classify complex datasets that algorithms running on classical computers struggle to handle. "We've shown a particular way of moving data into higher dimensions that would be hard for a classical computer but manageable for a quantum computer," says Antonio Córcoles at IBM in New York.

HEJERE, ETHIOPIA - Canada joined much of the world in barring the Boeing 737 Max 8 jet from its airspace on Wednesday, saying satellite tracking data show possible but unproven similarities between the Ethiopian Airliner crash that killed 157 people and a previous crash involving the model five months ago. The decision left the U.S. as one of the few remaining countries to allow the planes to keep flying. Canadian Transport Minister Marc Garneau said a comparison of vertical fluctuations found a "similar profile" to the Lion Air crash that killed 187 people in October. Garneau emphasized that the data are not conclusive but crossed a threshold that prompted Canada to bar the Max 8. He said the new information indicated the Ethiopian Airliner jet's automatic system kicked in to force the nose of the aircraft down after computer software determined it was too high.

While it may not lead to the next Cold War, the growing rivalry between the United States and China has certainly led to some frosty competition between the great powers. This is especially true of the tech sector, where some analysts liken the U.S. and China's heavy strategic investments in cybersecurity, quantum computing, 5G, and artificial intelligence to a digital arms race, one that, because of China's long-term positioning and access to vast amounts of data to train on, that country will win. But Anne-Marie Slaughter argues that when it comes to the world-shifting technology of artificial intelligence, the narrative isn't so simple. She explains why she is putting her money on the United States. Great power conflict isn't the only thing we at Future Tense have been fretting about this week.

DoorDash is getting in the car with General Motors' Cruise autonomous-vehicles to bring people food and groceries. General Motors has donated its first self-driving car, a 3-year-old Chevy Bolt electric car modified for autonomous operation, to the Henry Ford Museum. The car, GM Cruise Automation 01, will be on display immediately. "It'll be right at the front of the auto display, where we explain to people what a car is," The Henry Ford transportation curator Matt Anderson said Tuesday. The white hatchback, which sprouts sensors like a cat's whiskers, will be next to a '59 Cadillac in the museum's "Driving America" collection.

At the perfect intersection of technology and civil service, every government process will be an automated one, streamlining benefits, outcomes, and applications for every citizen within a digitally-enabled country. With that approach comes a significant layer of protocol that is necessary to ensure citizens feel empowered regarding decision-making processes and how their government addresses needs from a digital perspective. Right now, Canada is leading the world in AI, thanks largely to huge government investments like the Pan-Canadian Artificial Intelligence Strategy. The growing field is pervasive right now--there is hardly an industry it has not disrupted, from mining to legal aid. In fact, government might be one of the most obvious choices as to where automated decision processes can save time and money.

But U.S. officials have stood by their decision to keep the Boeing aircraft operating. The Federal Aviation Administration released a statement Tuesday that reaffirmed officials' trust in the safety of the jet, saying the aviation authority hasn't found any issues that would trigger an immediate grounding of the aircraft. The statement was released following a Dallas Morning News report that claimed pilots previously alerted U.S. officials about concerns regarding the model's autopilot system. In a separate report, the Times said Boeing's chief executive also personally called President Donald Trump to express his confidence in the jets.

An extended 5km (3.1 miles) no-fly zone for drones has come into force around airports in the UK after reported sightings at Gatwick, Heathrow and Dublin airports in recent months grounded hundreds of flights and left thousands stranded. Previously, only a 1km (0.6 mile) exclusion zone was in place. But despite the negative reputation they have received, the use of drones isn't all bad. From finding missing people to delivering takeaways, here are some of the ways the unmanned aircraft can be beneficial. A Norfolk man who went missing in June last year was only found when a police drone spotted him stuck on a marsh.

According to Digitimes Research, Taiwan-based server vendors, including suppliers of motherboards, end systems, storage devices and related network equipment, continue to enjoy growth in 2018. In terms of volume, global server shipments will show continuing growth throughout 2018 and 2019.
