Military Bird Drone - The overpopulation of certain birds and the need to increase society's resources, we assume that the combination creates adverse conditions in which the efficiency of productive processes is reduced, such as the world average level of crop damage of 15% or the 25% of fish farm production (according to FAO). data), or the population of invasive bird colonies. Humans have greatly reduced it, causing environmental damage. A cutting-edge solution to this problem is biomimetic drones.
To get away from insects that are considered bird pests, Kovat has developed a type of drone capable of scaring away these pests, protecting both crops and fisheries without harming bird life.
Military Bird Drone
This drone falls under the category of fixed-wing UAVs, has a wingspan of about two meters and weighs about 5 kilograms. In addition, its exterior is designed in such a way that it can be mistaken for predatory and/or territorial birds, such as eagles, hawks and even vultures.

, the system also benefits from the Veronte autopilot, through which it is possible to program the behavior of the drone as attack maneuvers, so that it imitates the behavior of the predator. In turn, it is also possible to program the route, thus autonomously covering the "surveillance" of a large area.
His work with the Veronte autopilot has proven useful in a collaboration with Covat, a company specializing in avian pest control using biomimetic drones.

Crashed Drone In Somalia Shows How The Military Hides Its Eyes In The Sky
Researchers from the University of Maryland, USA. The military may have just taken drone warfare to the next level.
Robo-Raven is a robotic bird whose wings can flap independently of each other. This technology makes the plane look like a live bird.
In fact, a YouTube video from the University of Maryland Robotics Department shows Robo-Raven in flight, a flight so real that the machine is attacked by a hawk at 1:49 of the video.
"Our goal is to create a robotic bird that can do things that have never been done before," said Dr. S. K. Gupta, a professor in UMD's robotics department, says in the video.
This New Russian Spy Drone Looks A Lot Like An Owl
The tactical ability is excellent. In Iraq and Afghanistan, insurgents bury or scatter weapons when they see or hear low-flying surveillance drones. With the technology used by Robo-Raven, a surveillance drone can fly overhead and no one would have a clue. Gear-obsessed editors handpick every product we review.

The Air Force wants miniature drones that can stay on a target for days or weeks before striking with an explosive warhead. The prototypes are already flying.
Battery power is the biggest limitation for small drones. A consumer quadcopter like the DJI Phantom can fly for half an hour or more. Fixed-wing craft such as the military's RQ-11B Raven extend up to 90 minutes, but are insufficient for long-term surveillance. One way around this problem is to land on the ground, while only the camera and communication systems draw power. The pose has two other advantages: a stationary drone is less obvious than an overhead spin and has a stable vantage point closer to the target. It is better to see from a tree 100 feet away than a hunter at 10,000 feet.
Some drones already have “track and steer” capabilities. AeroVironment's Qube, a quadcopter built for the police and military, can land on any flat surface with its long legs. Quadcopters can land easily, but landing is difficult for fixed-wing drones, especially when no flat surfaces are available. A really useful drone will be able to take advantage of street lights or tree branches to perch just as easily as a bird.
Russia's Deadly Artillery Drones Have A Strange Secret (updated)
The Air Force has done extensive research in this area, some of it under the Micro Perching Air Weapons Project. It calls for a bird-sized drone capable of landing on structures: "power lines, trees, buildings, terrain, etc." - send video back from up to three miles away, then take off again and land somewhere else. Similar to the current lethal Switchblade drone, the drone "would carry a small warhead on the order of half a pound of high-energy explosives that would be used to target people and/or light vehicles."
If you watch the recent thriller Eye in the Sky starring Alan Rickman and Helen Mirren, the movie not only features the USAF MQ-9 Reaper, but two other exotic drones that the Air Force wants to build. One looks like a bird, the other an insect. The drones in the movies have flapping wings, but the Air Force is taking the simpler approach of using fixed wings, or rotors. An air-borne microweapon can do something a film drone can't: recharge itself with solar cells or other means. "The ability to obtain energy/power from external sources is critical for continuous monitoring," the specification says. This will allow the drone to wait for the right moment to hit the target.
Getting on is an incredibly complex maneuver. Fortunately, birds perfected this technique millions of years ago, and researchers have gleaned a lot of valuable information from watching them in slow-motion video. The perch involves a well-controlled stop just above the perch, stopping in mid-air so the bird just floats to the surface. Even a clumsy fly like a heron can land perfectly on a fence, and drones should do the same.
Bhargava Gajjar of Vishwa Robotics developed a poseable leg for Hawk-based drones. The spring-loaded claws have a powerful grip that helps offset any residual momentum that might otherwise cause the drone to fly off its perch.

The Air Force did not choose Gajjar's design, but two other projects reached the prototype stage. A version of the Perching Micro Air Weapon, developed by Design Intelligence Incorporated with help from Oklahoma State University, looks like a bird and can fly almost anywhere. The drone has a modular design so that, like the Israeli ROTEM quadrotor, the payload can be changed from an intelligence version to a lethal attack version. However, they didn't actually put explosives on the drones. "The project was very successful, but the Air Force decided not to pursue it any further," DII CEO James Grimsley told the Prime Minister. DII is now dedicated to developing small solar-powered drones for commercial and non-military applications.
Other prototypes seem to have made more progress. 3 pounds The drone, made by Aethermachines Inc, is a more radical design that the company describes as "insect-like". The 3D printed drone has two overlapping rotors and takes off and lands vertically. The rotors act as wheels on the ground, so the bug drones can move around inside buildings and other enclosed spaces. It has a small ultrasonic sensor that allows it to stand, along with a set of accelerometers.
Flight time is only 10 minutes per charge, but the bug can be recharged in 40 minutes by sitting on a power line and using the power. This is his costume. Instead of pretending to be monstrous insects, drones are like other anonymous black boxes hanging near electrical appliances that no one notices. Ethermachines' bug is a bomber rather than a kamikaze, with "the ability to target and unload payloads, allowing the MAV [micro-air vehicle] to be turned around for reuse if the mission is not cost-effective ". The payload can be an explosive warhead or a marking dye. Later, the target becomes a marked individual who is then easily identified by the security forces.
In 2010 EtherMachines patented an initial design that already had all these elements: the
