Elon Musk's Gigafactory is taking shape: Drone footage reveals world's biggest building has added 2.4 MILLION square feet in just six months New drone footage of Tesla's Gigafactory shows that it is now 30 percent complete The north end of the massive building has been finished, adding another 4.5 million square feet of space It's deemed the biggest factory in the world – but when Tesla opened the doors to its'Gigafactory' earlier this year, only 14 percent was complete. Fast forward six months later and new drone footage reveals that the electric carmaker has more than doubled the size by adding an additional 2.4 million square feet of space to the campus Are aliens trying to contact Earth?

To deliver the Model 3 and its dream of an affordable, yet reliable electric car, Tesla needs the Gigafactory. The complex in Nevada will be used to produce batteries at an unprecedented scale, besting the might of every other factory in the world combined. Before that can happen, however, Elon Musk needs to build the darn place. Fresh footage by Matthew Roberts, shot with a DJI Phantom 3 drone in 4K, shows how far the project has progressed. As expected, there's still a long way to go -- only a handful of the 21 Gigafactory "blocks" have been completed so far. Even so, it's an enormous building that dominates the picturesque desert landscape.

The expansive interpretation of legal authority and strong defences of secrecy wielded by a president who at least understood the risks and downsides of drone warfare will now be available to an administration that sees the world in black-and-white, rather than shades of grey. The administration, moreover, continues to resist the release of other legal documents regarding the drone programme and to defend the significant reductions in documents that have been released (whether via government leak or through litigation), including the 11-page factual discussion in the July 2010 Office of Legal Counsel memo regarding the strike that killed American citizen Anwar al-Aulaqi in Yemen. Thus, while Obama has relied primarily on the AUMF for drone strikes, he has interpreted his statutory authority broadly.

Workhorse Group Inc. of Loveland, Ohio, received permission Wednesday from the Federal Aviation Administration to begin testing a delivery drone nicknamed HorseFly that is launched from atop the company's electric trucks. SAN FRANCISCO – The world's largest drone maker has teamed up with the nation's largest thermal camera company to create ready-to-fly drones that can see in the dark. The drone maker is DJI, a China-based company that currently has about 70% of the world drone market. The camera is by FLIR Systems, a Wilsonville, Ore.-based thermal and infrared imaging company. The collaboration will produce drones that can be used in search-and-rescue, firefighting, security and surveillance.

Millions of jobs could be lost to robots and automation by the year 2020 as part of the so-called "fourth industrial revolution," according to a World Economic Forum report from January. Jobs such as manufacturing and production are expected to be affected by the rise of the machines, while a whole new line of jobs will also be created, including I.T. and data analysis. However, the net loss is expected to be around five million jobs within the next three years. There may be a smidgen of hyperbole in that statement, but you only have to look at some of the developments of the past twelve months to realize that robots are here to stay and they will start adversely affecting employment. Here, we take a look back at some of the landmark moments and trends from across the robot realm in 2016.

At a price of $349, we were very impressed with everything ZeroTech packed into such a tiny drone. The only major negative we had with the Dobby is the battery life. In our testing, we were getting about 6 minutes of fly time before we needed to recharge. We were testing in very cold temperatures, so that might have shaved a few minutes off the battery life. Still, even ZeroTech only puts battery life at 9 minutes.

WASHINGTON – Millions of dollars' worth of U.S.-supplied drones that Kiev had hoped would help in its war against Russian-backed separatists have proven ineffective against jamming and hacking, Ukrainian officials say. The 72 Raven RQ-11B Analog mini-drones were so disappointing following their arrival this summer that Natan Chazin, an advisor to Ukraine's military with deep knowledge of the country's drone program, said if it were up to him, he would return them. "From the beginning, it was the wrong decision to use these drones in our (conflict)," Chazin, an adviser to the chief of the general staff of Ukraine's armed forces, told Reuters. The hand-launched Ravens were one of the recent highlights of U.S. security assistance to Ukraine, aiming to give Kiev's military portable, light-weight, unarmed surveillance drones that were small enough to be used widely in the field. They are made by AeroVironment.

It's no longer surprising to see postal services experimenting with delivering mail using drones. However, France is kicking things up a notch: its national mail service will be the first to deliver packages by drone on a regular route. DPDgroup, the express courier subsidiary of the mail service, is running a test program where a hexacopter drone (not shown here) will carry packages up to 6.6 pounds along a 9.3-mile route in France's southern Provence region. These are commercial customers using dedicated spaces to collect their orders, so you can't strictly compare this to Amazon's recent home delivery in the UK. It would be considerably more challenging to deliver to individuals, who don't have the luxury of secure areas or readily available staff.

In 2016, there were technological breakthroughs from improved object avoidance to a drone that can carry people. Drones also become more accessible with DJI's foldable Mavic Pro and almost Go Pro's Karma, but the latter was recalled after battery issues caused some of them to fall from the sky. Then in August, the FAA unveiled a certification process for drone pilots to fly legally. As the number of drone pilots multiplied, drone videos showed us parts of the world not previously viewable in ways that would have required big budgets and production crews. Here are a few of the most impressive videos that challenged our perspectives.

Postal workers in France are about to get a day off. The country announced a test program that will use unmanned aircraft to deliver packages once per week, according to a report from Ars Technica. The General Directorate for Civil Aviation, France's airspace regulator, has given drones the go-ahead to take over delivery duty on a limited basis. The crafts will take flight in the southern region of Provence, where they will travel a limited, nine-mile route once per week. Heading the trial will be DPDgroup, an international subsidiary of the French national postal service.
