The Army Research Laboratory is exploring a number of new autonomous vehicle, but none are quite as silly — or as potentially useful — as this new drone modeled after a flying squirrel. Why? You may ask. Because it can transform mid-flight.
Unlike other drones, this one will be able to land itself, conserve power, and gather intel. It will also be intelligent enough to detect walls, avoid obstacles and rapidly learn its environment.
Weighing in at half a pound, this drone focuses on one thing: weight. Normally, “to get this type of vehicle, you take a quadrotor and basically staple it to a fixed-wing aircraft,” according to Dr. Steve Nogar, a researcher with the Army Research Laboratory. “But it’s not very efficient.”
His model, the flying squirrel, helps to cut down on that weight and explores a drone’s ability to transform in mid-flight. “[It] tilts its rotors to go from hovering like a helicopter to speeding along like a sleek airplane,” according to an Army release.
This particular drone joins the ranks of a number of autonomous craft meant to modeled after animals. The Navy introduced a drone called the GhostSwimmer, which looks exactly like a bluefin tuna and performs reconnaissance missions at depths of up to 300 feet. And DARPA produced the Nano Air Vehicle, which mimics a hummingbird and scouts battlefields.
"Looking forward, we want to look at perching or landing on something in the environment," Nogar said. "That means we have to be able to sense the environment."
In addition to designing more efficient flying capabilities, Nogar is focused on the aircraft’s intelligence.
"If you're going to land on something, you need to know very quickly how fast that's coming up to you as you come in to land," Nogar said. "We will need to enable the UAV to sense and perceive its environment using visual techniques such as machine learning."
This whole project sounds ridiculous, but it’s oddly perfect. After all, Rocky was a flying squirrel, and he and Bullwinkle were instrumental in foiling the spies of Soviet satellite nations in the 1950s. This seems like a logical 21st century solution.
An Oregon Air National Guard F-15C Eagle that made an emergency landing on Wednesday ditched its entire arsenal of live air-to-air missiles before touching down at Portland International Airport, The War Zone reports.
President Donald Trump announced in December that he would withdraw all U.S. troops from Syria, but Sen. Lindsey Graham has since made a strong push to keep a small residual force along the Turkish border along with troops from European allies.
The former Navy SEAL among a group of eight men arrested earlier this week in Port-au-Prince on weapons charges says he was providing security work "for people who are directly connected to the current President" of Haiti.
"We were being used as pawns in a public fight between him and the current Prime Minister of Haiti," said Chris Osman, 44, in a post on Instagram Friday. "We were not released we were in fact rescued."
It's a photo for the ages: a Marine NCO, a Greek god in his dress blues, catches the eye of a lovely young woman as her boyfriend urges her on in distress. It's the photographic ancestor of the much-loved "distracted boyfriend" stock photo meme, made even sweeter by the fact that this is clearly a sailor about to lose his girl to a Devil Dog.
Well, this photo and the Marine in it, which hopscotched around Marine Corps Facebook and Instagram pages before skyrocketing to the front page of Reddit on Thursday, are very real.
The photo shows then-Staff Sgt. Louis A. Capozzoli — and he is absolutely not on his way to steal your girl.
