You could soon be sharing the sidewalk with robots in D.C. A test project will be presented to District leaders to allow delivery robots to operate on city sidewalks. WASHINGTON - You could soon be sharing the sidewalk with robots in D.C. A test project will be presented to District leaders to allow delivery robots to operate on city sidewalks. These robots could be delivering your takeout meal or maybe some fresh groceries.

Most golfers feel the trip from the green to the clubhouse for refreshments can be a pain. Now Rakuten, a Japanese firm, has unveiled a snack-delivery service for golfers that uses drones. Golfers order anything from drinks to replacement balls through an app and receive the items from a quadcopter in just minutes - which means they never have to leave the course. Rakuten, a Japanese firm, has unveiled a snack-delivery service for golfers that uses drones. Golfers place their order using an accompanied at that they download on their smartphones.

More than 50 U.S. airports will test a new system to make themselves more aware of drones flying near their runways. Airport executives and the drone industry expect the Digital Notice and Awareness System (D-NAS) to improve safety amid concerns raised by 764 drone sightings near airplanes in 2015. Drone hobbyists are required to notify airports of their plans when flying within five miles of an airport, but doing so has been a difficult process. For one, hobbyists have to track down the appropriate phone numbers. "You don't want to give out air traffic control's phone number on a public website for obvious reasons. Well, how are you going to manage that?" said Steve Runge, division manager of the Houston Airport System's safety and emergency management.

The ancient ruins of Palmyra, one of Syria's oldest cities, have stood for 3,000 years, but, since last May, the Unesco World Heritage site has been facing some of the most brutal threats to its existence. Located in an oasis northeast of the Syrian capital of Damascus, Palmyra has become a significant symbolic and military position in the now 5-year-old Syrian conflict. After seizing the city of roughly 50,000 residents last May, the Islamic State group was forced out of Palmyra over the weekend by forces loyal to Syrian President Bashar Assad. On a strategic level, retaking Palmyra gives the Syrian regime a strong military base for future operations against the militants' other strongholds as well as renewed control over some of Syria's most important oil and gas fields. But regaining Palmyra is also a highly symbolic win for the Syrian regime -- now trying to salvage whatever is left of the ancient ruins -- in its quest to position itself as a key partner in the fight against the terrorist group, also known as ISIS. An aerial view of the historic city of Palmyra, in Homs Goveronorate, Syria, is seen in this still image taken from a drone video, March 28, 2016.

And the artificial intelligence chatbot that didn't survive a day on the Internet. Plus: Reviewing Santiago Calatrava's latest, how to be unprofessional and the "Grand Theft Auto" modification that may have you watching for hours on end. Time has Russian drone footage that provides an overview of what remains of the old Silk Road crossroads, as well as the contemporary human settlement of Tadmur that sits nearby. About 80% of the artifacts appear to be largely intact. The country's antiquities chief says repairs will take five years.

There are about 2.5 million drones in the US and not one has collided with a piloted aircraft – yet. With nearly 600 close-calls reported from August 2015 to January 2016, the Federal Aviation Administration worries it is only a matter of time before there are disastrous incidents. This data shows an urgency for effective anti-drone systems to deal with rogue UAVs, as more unmanned vehicles take the sky. More than 406,000 drone owners have registered their vehicle with the Federal Aviation Administration (FAA) since late December. There are about 2.5 million drones in the US and not one has hit with a piloted aircraft – yet.

Rakuten, just like Amazon, is experimenting with drones that can quickly deliver goods to its customers. Unlike Jeff Bezos' company, however, the e-commerce giant is starting small with a service designed for golfers. From May, players at a specific course in Japan's Chiba prefecture will be able to take out their phone and request some new golf balls or refreshments. A Mini Surveyor drone developed by the Autonomous Control Systems Laboratory -- a company from Chiba which Rakuten has now invested in -- will then fly them over from a base station near the course's clubhouse.

But while the idea of sinking your teeth into a tasty slice can be appealing, the bummer is the pesky delivery guy, who loiters in the doorway judging your slovenly outfit and your measly tip. They're fully enclosed, four-wheeled carbohydrate-dispensing machines, complete with heated and cooled, lockable compartments that require the purchaser to enter a passcode to retrieve their delivered food. Its space-age, Kubrickian exterior styling is sure to appeal to middle-age sci-fi geeks as well as neighborhood paintball enthusiasts. Domino's Pizza--which happens to share its hometown of Ann Arbor, Michigan, with Car and Driver--has a long history of delivery innovation, including in recent years electric vehicles and Chevrolet Spark–based custom delivery wagons. When it came time to go robotic, Domino's called in Australian technology startup Marathon Targets to help in the creation of its autonomous delivery vehicles.

Humans have always used tools to create art, but paintbrushes, pens, and chisels don't have an agenda of their own; they bend to the will of the person wielding them. But a project by students at the MIT Media Lab's Fluid Interfaces Group ponders what happens when a machine has a voice in the artistic process. In this case, the machine is a drone, and that drone is essentially a flying phantograph. As a human draws with a pen, a camera captures the motion and a computer communicates it to the drone, which mimics what the pen is drawing. In the video you see a person make a sweeping gesture across a canvas; the drone mirrors it, creating a similar mark on its own canvas.

Drone attacks killed eight men suspected of belonging to al Qaeda in southern Yemen on Saturday night, local residents said, as a U.S. campaign against the militant group goes on amid a wider civil war in the country. Two missiles hit the fighters who had gathered in courtyards in the villages of al-Hudhn and Naqeel al-Hayala, residents from the southern coastal province of Abyan told Reuters by phone. Al Qaeda in the Arabian Peninsula (AQAP) has taken advantage of a war pitting the Iran-allied Houthis against forces loyal to exiled President Abd-Rabbu Mansour Hadi to grab territory and operate more openly. The group has carried out attacks against the Yemeni state for years, plotted to blow up U.S.-bound airliners and claimed responsibility for the January 2015 attack in Paris on a French magazine that killed 12 people. The United States has kept up a drone campaign against the militants, although it evacuated the last of its military and intelligence personnel from Yemen in March last year.
