The camera market has long been segmented into three basic categories: Cameras for professionals, models for the so-called "serious hobbyists," and models for the newcomer. From DSLRs to action cams and point-and-shoots, most cameras are squarely aimed at one of these three markets. The market for aerial photography (aka drones with real cameras on them) is about 150 years younger, and therefore somewhat less segmented. Up until now, there have been only two categories: Professional drones and hobbyist drones. Automated flight modes make it possible to get good quality video and photos without the learning curve of more expensive drones.

Swiss authorities have added another security measure for this year's World Economic Forum in Davos: anti-drone guns. Bloomberg has spotted local police preparing HP 47 Counter UAV Jammers to make sure no unmanned aerial vehicle (UAV) gets too close to the venue, whether it's sent by a spy organization or just a nosy onlooker. That's the same jammer the German police used in Berlin when President Obama visited the country. The publication says authorities decided to bring in an anti-drone technology, because people with malicious intent could use UAVs to monitor security positions or even to launch attacks. "While drones have great potential, they have -- just as every new technology or aspect of the Fourth Industrial Revolution -- also a potential downside. The forum takes the safety and security of its participants seriously. It is therefore normal that we take any potential issue into account and prepare for it."

That's what happens when you're shooting with an in-the-air camera meant to shoot in automatic exposure. PolarPro co-founder Austen Butler stopped by the #TalkingTech garage here to show off the new filters, carrying case and landing gear for the Mavic. You can watch a replay here. Tech nerd alert: we shot the broadcast on the Mevo camera, which allows you to zoom in and out, via the smartphone app. The PolarPro filters start at $79.99 and come in groups of three.

A cloud of 3D-printed drones big enough to bring down the latest U.S. stealth fighter, the F35, was just one of the combat scenarios evoked in a discussion of the future of warfare at the World Economic Forum in Davos on Wednesday. Much of the discussion focused on the changes computers are bringing to the battlefield, including artificial intelligence and autonomous systems--but also the way the battlefield is coming to computing, with cyberwar, and social media psyops an ever more real prospect. Former U.S. Navy fighter pilot Mary Cummings, now director of the Humans and Autonomy Lab at Duke University, delivered the first strike. "The barrier to entry to drone technology is so low that everyone can have one, and if the Chinese go out and print a million copies of a drone, a very small drone, and put those up against an F35 and they go into the engine, you basically obviate what is a very expensive platform," she said. Drones could not only defeat the F35, on which the U.S. is spending what Cummins called "a ridiculous amount of money," but also replace them, she said.

The US army wants a missile that could shoot a swarm of weaponised drones over a target area. The idea would be to equip existing missiles with the ability to dispense multiple "smart quadcopters" after launch. On release, the quadcopters would unfold, decelerate and fly off under their own power to attack different locations. A single missile could therefore knock out multiple targets. The drone-firing weapon is outlined in a solicitation for design proposals from the Department of Defense.

Iris Automation Inc. has raised $1.5 million to bring "sense and avoid" technology, and truly self-flying capabilities, to drones used for industrial tasks. Even for human pilots, identifying obstacles and deciding precisely how to maneuver a fast-flying aircraft around them poses a serious challenge. Iris' technology analyzes and draws insights from videos captured by cameras on-board a drone in real time. "We're designing this to work like a human pilot's vision and decision-making process," says Iris Automation CEO and cofounder Alexander Harmsen. Iris Automation, a Y Combinator company, is not alone in the quest to develop computer vision systems that can make unmanned aerial vehicles, and eventually other robotics and vehicles, truly autonomous.

When you're zipping through the air at 60 kilometres per hour, it can be hard to work out where you're going. But now drones can create detailed 3D maps as they fly – an advance that could let them navigate the world free from human input. Called Hydra Fusion, the system could one day allow drones to use a form of navigation known as simultaneous localisation and mapping to find their way in unfamiliar spaces – just as some robots do on the ground. It will also make them better at aerial surveillance. Hydra Fusion works by stitching together multiple images – in this case, consecutive frames of footage from a drone's video camera – to form a detailed 3D map while it is in the air.

EagleEye says its tech gives drones military-grade security and the possibility of flying autonomous missions. In 2014, three software engineers decided to create a drone company in Wavre, Belgium, just outside Brussels. All were licensed pilots and trained in NATO security techniques. But rather than build drones themselves, they decided they would upgrade existing radio-controlled civilian drones with an ultra-secure software layer to allow the devices to fly autonomously. Their company, EagleEye Systems, would manufacture the onboard computer and design the software, while existing manufacturers would provide the drone body and sensors.

A team of Airbus engineers are developing a self-flying taxi that is designed to fly above traffic to carry individual passengers and cargo throughout busy cities. The utopian vision is a bit far-fetched, but they plan to start testing a prototype of the vehicle in late 2017. The technical leader of Ford's autonomous car project speaks about what it's like to be driven by a driver-less car, and how big a deal self-driving vehicles will really be. In Airbus's corporate magazine FORUM, project executive Rodin Lyasoff asserts, "In as little as ten years, we could have projects on the market that revolutionize urban travel for millions of people." The project, dubbed Vahana, launched in February 2016 at A3, which is Airbus Group's innovation division based (where else?) in Silicon Valley.
