Scientists turned dead birds into drones that can fly.



Researchers turned stuffed birds into robots. Bird-shaped robots can observe humans and other animals. Stuffed animals are quite easy to turn into robots. Things like deer's skin can also use to cover the robot. And that skin or fur can dress on a four-leg robot. Stuffed fish and stuffed snakes can also use as robots. 

But as I wrote earlier, the dead bird turned to the flying drone. And that thing is one of the most powerful tools in the world. The animal-shaped drones and robots can observe other humans or animals. Researchers can use animals like rats and crows as covers for the surveillance robots. Researchers could use some common animals that have only a few enemies. That makes those robots invisible. 

Those animal-shaped robots can have multiple sensors. They can have microphones, laser microphones, sonar systems, and CCD cameras. They also can carry chemical detectors like plasma spectrometers. So those sensor packs make those robots effective. 

The animal-shaped robots can also use as attack tools. In the feet of those robots can install electric batons. And they can be used in capture operations. They can carry explosives, small pistols, and chemical weapons that are in those robots' mouths. That kind of system can use in covert operations.

AI doesn't create new things. They just recycle old ones.

 



Even the best AI cannot generate a thing. It just recycles old ones. When we think about paintings. And other things that AI. The truth is that it only connects details from sources that somebody else made. In real life, it connects information or details from multiple sources. The number of sources determines how effective and smooth results the AI can create.

The weakness is that the AI doesn't understand what it does. Productive AI like Chat GPT selects a certain number of sources by using the search engine's results. Then the AI just select one or two paragraphs from those homepages and connects them to a new entirety. 

And here is the danger. The AI doesn't know what is reading in those paragraphs. The thing is that the AI recognizes the paragraphs. But because it doesn't know what is reading in those paragraphs. The AI can choose something that doesn't belong to any topics in the text. That means AI is far away from human intelligence.  

So do we need scholars in the time of AI? The answer is that humans still in a vital role in machine learning. The AI can even collect thesis from homepages that human is prechecked. AI can play chess better than humans because it can calculate possible movements so far ahead. The AI can fly aircraft closer to the ground than humans because it doesn't afraid.

It just needs two or four radars that can fly in canyons. And of course, GPS and map where is the profile of the canyon. The radar altimeter can measure the aircraft's distance to the ground. And side radars tell the distance to walls. 

The nose radar sees the possible obstacles. But that thing is not anything there the AI creates new things. An interesting thing about AI is that self-driving car requires more complicated code than drone needs. 

The learning AI can learn multiple canyon profiles. It just records the aircraft's route. When we make self-driving cars, they need much more variables than robot aircraft needs for a successful mission. 

Every variable is an object that the system must recognize. The AI-driven car simply stops the vehicle and says that the driver must use the manual system in city areas. The AI can make many complicated-looking things, but all those things that AI knows must be pre-program in its memory. Otherwise, AI is ineffective. 

But when we think about the future and autonomously learning AI, we must realize one thing. The human brain requires information that it uses for connecting memory blacks. 

The problem is this. We don't know the precise moment when the data collection begins. 

The human brain involves 86-500 billion neurons. Calculating those neurons is difficult because of things like the number of axons. And the ability to interconnect neurons together has a great effect on the brain. The number of connections between neurons is the same way important. As the number of physical neurons.

Drones are deadly weapons.

Shahed-136


The Ukrainian war shows how effective tool drone is. The Russian air defense could destroy all Beyraktar drones. But before that, the Bayraktars terminated lots of Russian equipment and men. So the efficiency of those drones is good. 

Another name for loitering ammunition or kamikaze drones is cruise missiles. The problem is that almost anybody can make the kamikaze drone at home. Basically kamikaze drone is an RC airplane that carries explosives. 

There are also anti-tank versions of those loitering ammunition. Those versions are just artillery recon drones or target drones equipped with suitable warheads. 

And even if Russian air defense destroyed them.  Those drones played a big role at the beginning of the war. Today we see how effective cheap Iranian drones are against fixed Ukrainian targets.

Lucky for Ukraine, Shahed-136 drones are very primitive. They can fly by using fixed routes. And they don't even change altitudes. 

Shahed-136 cannot make any escape and evasion movements. So when that drone is located. It's quite easy to shoot down. 

And even if Ukrainian air defense shoots most of those slow drones. A couple of them are reaching targets. This is the key element in drone operation, lots of cheap drones can send at the same time, against multiple targets. The maximum speed of those drones is about 150 km/h. Even if those drones are easy to reach by using a car or combat helicopter. And they are easy to destroy. 

A large number of those loitering ammunition guarantees that some of them reach the target. Drones are like all other aircraft. They are hard to see but easy to destroy if the ammunition hits them. The new anti-aircraft missiles are effective against drones. But the problem is that they must see drones before they can be used.

The price of effective missiles like Patriot is 3 million per shot. Their target price is less than 3000 dollars. The number of lost drones in missions in 2020 was 24. And it increased. But then. The high command can accept the loss of 24 drones because no friendly crews were dangered. 

The low price of the GPS systems means that the cheap mobile telephone can modify the brain of those drones. And GPS/GLONASS guarantees high enough accuracy that those drones can destroy or damage oil refineries, power plants, transformer substations, factories, and other large structures. 

The small drones that Ukrainians use against Russian infantry and armored vehicles are also very effective. Those drones are just little modified versions of drones that people can buy from supermarkets. 

Those drones are equipped with systems that can drop hand grenades at enemy positions. Sometimes those hand grenades slipped into tanks from the open hatches. And that destroyed those tanks. If those small-size drones are equipped with thermobaric hand grenades the lethal radius of those bombs is 30 meters. 

The Ukrainian military also used pocket-size killer drones that can take off individual shooters. In the wrong hands, those pocket-size drones can cause a big risk to national security. They can leave in position. And then those drones can attack their targets. The small miniature drones can control by using satellite data transmission. And those drones are giving ICBM missiles the ability to kill individual people from the streets. 

The killer drones and loitering ammunition can have similar target recognition and attack capacity as Javelin missiles. There are multiple different drone variants in use. Some drones are equipped with similar radiation-homing equipment with HARM (High-Speed Anti-Radiation Missiles). This makes them effective against radio transmitters. That kind of drone can destroy any radio source.

The thing that makes drones dangerous is advancing technology. When we think that a 60 € mobile telephone can give drones the same accuracy that made in the 1990s by using equipment that cost millions of Euros, we must concern about the future. The reason for that is. All models that we made against drones are old fashion. 

Image recognition systems are giving drones pinpoint accuracy. And the first supersonic drones are in use. AI-controlled weapons are under development. And the fact is that the fear that Russia or China will be first is making other nations create new terminator weapons. If those international contracts limit that development, we are in big trouble. 

International contracts limit many things like the development of nuclear, biological, and chemical weapons. But those weapons are under development. 

International laws prohibit things like extortion. But somehow, those cases happen quite often. Drones are big ammo over the battlefield. If we think, that some country loses 24 tanks in the mission, that is not the end of the tank. In the case of war, we must realize that somebody doesn't care about contracts.

Could there have been UFOs in Earth's orbit in the 1950s?

Aligned, Multiple-Transient Events in the First Palomar Sky Survey could be artificial objects. Or. They could also be some light reflection...
