Light show with 3,281 drones breaks Guinness World Record
A luxury car company broke a Guinness World Record in China by using 3,281 drones to put on a light show in the night sky.

The Genesis light show in Shanghai, which celebrated the brand's launch of the Genesis G80 car, featured 3,281 unmanned aerial vehicles, or UAVs, being arranged in multiple 3D images including depictions of the Genesis G80 and GV80 cars.

Volocopter shows off its vision for a commuter drone taxi
German aviation outfit Volocopter has shown off another concept craft, this time aimed at capturing the commuter market. The VoloConnect is intended to transport up to four passengers over distances of up to 64 miles, taking people “from the city to […] suburban areas.” In the release, the company says that the craft uses a hybrid lift and push design to electrically move bougie one percenters at speeds of up to 111 miles per hour.

Drones may have attacked humans fully autonomously for the first time
Military drones may have autonomously attacked humans for the first time ever last year, according to a United Nations report. While the full details of the incident, which took place in Libya, haven’t been released and it is unclear if there were any casualties, the event suggests that international efforts to ban lethal autonomous weapons before they are used may already be too late.

The robot in question is a Kargu-2 quadcopter produced by STM.

Watch: Drone crashes into erupting Icelandic volcano

2 hours ago

A drone trying to film the erupting Fagradalsfjall volcano has crashed into a lava spew.

YouTuber Joey Helms wanted a close up view of the spectacle, but the flight didn't go quite to plan.

The volcano has been erupting since March.

New drone is first to reach Level 4 autonomy

1st June 2021

Exyn Technologies, a pioneer in aerial robot systems, has announced the highest documented level of aerial autonomy.

Exyn's drones are now capable of Level 4A autonomy – meaning they are immune to GPS signal loss, with all spatial and mapping computations able to be performed onboard, the company said. This enables free-flight exploration of complex spaces, with full determination of flight paths at over 2 m/s flight speeds (double the previous standard), and higher quality data collection in larger volumes. Under ideal conditions, Exyn's drones can cover 16 million cubic metres in a single flight, the equivalent of nine football stadiums.

[...]

In simple terms, comparing previous autonomy standards with that of Exyn is like the difference between self-navigating a single, defined road versus uncharted terrain in unknown and unmapped territory. Unlike a car, however, a drone must be able to manoeuvre within three dimensions and pack all its intelligence and sensors onto a fraction of the total body size with severe weight restrictions.

I speak for millions when I say "I've been waiting for a video like this for years."

So many drones, so few sacrifices in the name of science.

Sony's First Drone Is a $9,000 Professional-Grade Beast
Earlier this year, Sony teased the development of its first-ever drone, and today that drone is finally getting an official debut. Say hello to the $9,000 Airpeak S1. Yes, that’s right: $9,000.

With a starting price just shy of $10,000, the Airpeak S1 is aimed squarely at professional filmmakers, and while that might be out of reach for regular folks looking for a new high-end drone, the Airpeak’s specs are pretty impressive.

Not only can the Airpeak S1 hit a top speed of 55 mph in just 3.5 seconds (which Sony claims is faster than any comparably priced drone from DJI), it’s the smallest drone that can be equipped with a full-frame interchangable lens mirrorless camera. Instead of using a small built-in sensor and camera module, the Airpeak S1 was designed to carry a range of Sony mirrorless cameras, including various versions of the a9, a1, a7r, a7s, and the recently announced FX3. (Sony says other mirrorless camera may work with the Airpeak too, but the company has yet to test any for official compatibility.)

Creating 'digital twins' at scale to improve drone deliveries

by Becky Ham, Massachusetts Institute of Technology
https://techxplore.com/news/2021-06-dig ... eries.html
Picture this: A delivery drone suffers some minor wing damage on its flight. Should it land immediately, carry on as usual, or reroute to a new destination? A digital twin, a computer model of the drone that has been flying the same route and now experiences the same damage in its virtual world, can help make the call.

Digital twins are an important part of engineering, medicine, and urban planning, but in most of these cases each twin is a bespoke, custom implementation that only works with a specific application. Michael Kapteyn has now developed a model that can enable the deployment of digital twins at scale—creating twins for a whole fleet of drones, for instance.

A mathematical representation called a probabilistic graphical model can be the foundation for predictive digital twins, according to a new study by Kapteyn and his colleagues in the journal Nature Computational Science. The researchers tested out the idea on an unpiloted aerial vehicle (UAV) in a scenario like the one described above.

Manufacturing drone wings with locust wing capabilities
https://techxplore.com/news/2021-07-dro ... ities.html
by Bob Yirka , Tech Xplore
A team of researchers from the University of Lincoln in the U.S. and Huazhong University of Science and Technology and Guangzhou University, both in China, has developed a way to manufacture drone wings with locust wing properties, allowing drones to glide for long distances. In their paper published in the journal Royal Society Open Science, the group describes how they developed their technique and how well it worked when tested.

Prior research has shown that locusts are able to fly long distance because they are able to take advantage of air currents and their species' swarming characteristics. Prior research has also shown that mimicking natural creatures can sometimes reap rewards when building human machines. In this new effort, the researchers began with the idea that drones or airplanes with some of the features of locusts might be better at gliding, a feature airplane makers covet because it can result in reduced fuel consumption and also a reduction in noise. But instead of designing a plane with locust-inspired wings, the researchers looked at several of the features of locust wings and developed ways to manufacture copies that take advantage of their special properties, for both drones and small airplanes.

The US Marines are testing flying, remote-controlled grenades
With hands held overhead, the Marine waits for the grenade to spin up, and then releases it into the air. With a drone and its four rotors attached to the top of its body, the grenade takes off, a gentle flight for the typically hand-tossed munition. Later in those same exercises, the grenade, still unexploded in this exercise, flies back for a landing, and the Marine catches it by a tether.

This scene took place July 7 at Camp Lejeune, North Carolina, as part of a training exercise. The flying grenade is a Drone 40 modular quadcopter. It can be either a scout or a loitering grenade. In action, it looks goofy, like someone saw a “Sky Dancer” flying toy from the 1990s and decided it would be a great basis for a bomb.

What sets the Drone 40 apart from a host of other small drone designs is the long, vertical fuselage. Unlike most quadcopters, which are wider than they are all, the Drone 40 is alien in appearance. The shape of its body, and the name, both refer to the 40mm grenade launcher, a standardized way to hurl an explosive in battle. The Drone 40 can be both hand-tossed, as in the video below, or it can be fired as a grenade from a launcher.
