A Chinese research expedition claims to have made major breakthroughs operating Unmanned Underwater Vehicles (UUV) collecting hydrographic information with potentially significant military application for submarine operations. While the original Chinese report hints at some possible advances in underwater data transmission, most subsequent reporting exaggerates the UUVs’ potential tactical utility as tools against foreign submarines.

Xinhua reported that scientists aboard the research vessel Kexue are operating 12 UUVs simultaneously for the next month collecting hydrographic data like salinity, temperature, turbidity, and current information that is being transmitted back in real-time. While details are sparse, two advances are implied, in operating multiple UUVs in coordination, and in underwater data transmission relaying the information they collect to data centers in real-time.

The South China Morning Post provided some amplifying details on the Kexue’s work. The UUVs, called Haiyis, are a type of buoyancy glider. Buoyancy gliders have been in use for years to collect hydrographic data for both civil and military uses. Unlike most UUVs that operate like small submarines, they do not rely on powered propulsion. Instead, buoyancy controls cause the glider to cyclically rise and sink, and as it does, the flow of water over the glider’s “wings” propel it forward.

Yhdysvaltalainen Duke Robotics kertoo ratkaisseensa, miten esimerkiksi rynnäkkökiväärin saa liitettyä kauko-ohjattavaan multikopteriin. Yrityksen kehittämän rekyylin poistavan teknologian myötä pienen kauko-ohjattavan lennokin voi varustaa rynnäkkökiväärillä ja kranaatinheittimellä.

Yrityksen mukaan sen kehittämä teknologia ja kopteri kykenevät operoimaan useilla erilaisilla asetyypeillä.

Duke Roboticsin mukaan TIKAD-järjestelmä absorboi aseiden rekyylin. Rekyyli on luodin liikesuunnan vastainen aseen ”potkaisu”.

Yritys kutsuu teknologiaansa tulevaisuuden sotilaaksi ja kauppaa sitä muun muassa Yhdysvaltain armeijalle kaupunkisotien työkaluksi.

”Klassinen armeija armeijaa vastaan sodankäynti on entistä harvinaisempaa ja sota on muuttunut sissisodaksi. Toistaiseksi aseiden käyttö kauko-ohjattavissa pienkoptereissa ei ole ollut mahdollista. Nyt on”, Duke Robotics sanoo tiedotteessaan.

This 32 second video taken in September of 2001 shows two NASA F/A-18s performing a flight test over California's Mojave Desert during the Autonomous Formation Flight (AFF) program at Dryden Flight Research Center (now Armstrong). Autonomous Formation Flight (AFF) is intended to allow an aircraft to fly in close formation over long distances using advanced positioning and controls technology. It utilizes Global Positioning System satellites and inertial navigation systems to position two or more aircraft in formation, with an accuracy of a few inches. This capability is expected to yield fuel efficiency improvements.

Ten years ago, researchers thought that getting a computer to tell the difference between a cat and a dog would be almost impossible. Today, computer vision systems do it with greater than 99 percent accuracy. How? Joseph Redmon works on the YOLO (You Only Look Once) system, an open-source method of object detection that can identify objects in images and video -- from zebras to stop signs -- with lightning-quick speed. In a remarkable live demo, Redmon shows off this important step forward for applications like self-driving cars, robotics and even cancer detection.

Uusi tapa jemmata lennokkeja. Pystyisikö ihminen tähän täysikokoisella lentokoneella ilmakehässä?

UAV designs are a perpetual compromise between the ability to fly long distances efficiently with payloads (fixed-wing) and the ability to maneuver, hover, and land easily (rotorcraft). With a very few rather bizarre exceptions, any aircraft that try to offer the best of both worlds end up relatively complicated, inefficient, and expensive. The ideal fantasy UAV would be a fixed-wing aircraft with the magical ability to land on a dime, and a group of researchers from the University of Sherbrooke in Canada have come very close to making that happen, with a little airplane that uses legs and claws to reliably perch on walls.

A small Florida company has outfitted a quadcopter with a sniper rifle, grenade launcher and other small arms — and wants to sell the technology to military forces.

Duke Robotics Inc. of Gulf Breeze is already filling orders of the TIKAD drone for Israeli forces, according to a company promotional video on YouTube (see below).

The small quadcopter can be equipped with an SR-25 marksman rifle made by Knight’s Armament Co.; an M321A grenade launcher; and an M4 rifle made by Colt Defense and FN America.

The drone “takes the full recoil of the weapon discharge, compensates for its force and quickly readjusts to stay on target and in the fight,” the promotional video states.

Ehkä valaisudrone on toimiva konsepti, mutta taistelunkestävyys on ongelma. Ehkä se ei tarvitse koska valaisu on uskomattoman kirkas ja kohde on pienempi kuin mitä spottivalo näyttää etusektorista.

En oikein näe ongelmaa noiden taistelunkestävyydessä, jos siis lennokki on tarpeeksi halpa. Antaa vihollisen yrittää ampua niitä alas, jos onnistuvat, niin laitetaan puolen tusinaa uutta ilmaan ja antaa vihollisen paljastaa asemiaan ampumalla. Sopivalla automaatiolla parvi droneja voi vuorotella valaisussa, joten lennokkien kantamien valojen ei tarvitse olla päällä koko aikaa eikä osoittaa muualle kuin halutulle alueelle.
 
Some of the world’s leading robotics and artificial intelligence pioneers are calling on the United Nations to ban the development and use of killer robots.

Tesla’s Elon Musk and Google’s Mustafa Suleyman are leading a group of 116 specialists from across 26 countries who are calling for the ban on autonomous weapons.

The UN recently voted to begin formal discussions on such weapons which include drones, tanks and automated machine guns. Ahead of this, the group of founders of AI and robotics companies have sent an open letter to the UN calling for it to prevent the arms race that is currently under way for killer robots.

In their letter, the founders warn the review conference of the convention on conventional weapons that this arms race threatens to usher in the “third revolution in warfare” after gunpowder and nuclear arms.

The founders wrote: “Once developed, lethal autonomous weapons will permit armed conflict to be fought at a scale greater than ever, and at timescales faster than humans can comprehend. These can be weapons of terror, weapons that despots and terrorists use against innocent populations, and weapons hacked to behave in undesirable ways.

“We do not have long to act. Once this Pandora’s box is opened, it will be hard to close.”

Watch: Israeli Air Force welcomes new and improved UAV to its ranks

This week, the Israeli Air Force introduced a new unmanned aerial vehicle manufactured by a subsidiary of Elbit called The Star. The aircraft can spend 30 hours in the air and reach a maximum speed of 137 miles per hour.

Meet the new rising "Star" of the Israeli Air Force: The Hermes 900 aircraft, an unmanned aerial vehicle nicknamed "The Star," has now become operational after it underwent a series of practice drills and test flights.

The Star is an improved version of the Hermes 450 aircraft and is manufactured by Silver Arrow, a subsidiary of Elbit. It is 30 feet long with a wingspan of 52 feet and can reach a maximum speed of 137 miles per hour. The Star can stay in the air for up to 30 hours.

The IDF emphasized that the main objective was to double the strength and capabilities of the UAV in as many aspects as possible: Size, carriage capacity, air time and flight range. With its technologically advanced sensors and improved capabilities, The Star can be used for reconnaissance and control, force protection, enemy tracking and more.

In order to become fully operational, the Star had to undergo a series of test flights and combat strategy adaptation. The process began at the beginning of Operation Protective Edge in 2014 and within a few days was able to perform its first mission on July 15, 2014.
 
The U.S. Army announced today it has concluded it's Micro Autonomous Systems and Technology program after a series of tests and demonstrations over the last week.

The program has existed since 2008 and involved the Army Research Laboratory, industry participants and university researchers. It culminated in technology demonstrations at Aberdeen Proving Ground in Maryland Aug. 22-24, including the testing of a swarm of autonomous quadcopters that can assume formations.

"I think there's still a long way to go to get them to do all of the behaviors we want in any type of environment," Army collaborative manager Dr. Brett Piekarski said in a press release.

"There are certain areas where I think we've really pushed the bar and moved the state-of-the-art. One example is in scaling things down to be able to do autonomous behavior in something that fits in the size of your hand."

The project has been conceived as a five-year research alliance that was extended to a decade to develop micro drones that would be capable of coordinating their actions without outside input. It included 19 members of defense industry companies and public and private universities.

"We've demonstrated what can be done in this space with some innovative ideas," Piekarski said.

"There needs to be a lot of work in all of these areas to get them into engineered solutions that we can put in the hands of the Soldiers."

A successor collaborative program called the Distributed Collaborative Intelligent Systems and Technology has recently been announced by the Army.

"The convergence of technology that we're witnessing now, and as we propel it forward, is going to be a dramatic lifesaver and game-changer in terms of the way we operate tactically," said Army senior research specialist Dr. Bran Sadler.

"This is my opinion. I am extremely optimistic."

Less than a week after the last drops of Hurricane Harvey fell, Houston is just beginning to assess the damage. At least 46 people have died. More than 30,000 houses are flooded and as many as a million vehicles waterlogged. Early estimates suggest the hurricane has inflicted $120 billion in damage on the region, making it the most expensive natural disaster in the country’s history.

“This is going to be a massive, massive cleanup process,” Texas governor Greg Abbott told ABC’s Good Morning America on Friday. “This is going to be a multiyear project for Texas to be able to dig out of this catastrophe.”

Which means the drones’ work has just begun. Responding to the disaster provides a major test—and opportunity—for the country’s fast-growing network of professional UAV operators, almost exactly one year after the Federal Aviation Administration began to hand out licenses for commercial drone operation. (There are at least 2,000 licensed pilots in the Houston area alone, and some 20,300 nationwide.)

“This is the one of the first big disasters where we can show how valuable drones can be,” says Brandon Stark, who directs the Center of Excellence on Unmanned Aircraft System Safety at the University of California, Merced. In the coming weeks and months, they'll help locals assess damage to homes, roads, bridges, power lines, oil and gas facilities, and office buildings—and determine whether it's safe to go back.
