At this time, no one complained about Lin Zheng's clothes anymore. Even the people who were hiding in the backstage to watch Lin Zheng's speech were all very slutty: relying on the advantages of organizing various exhibitions, they are well-informed and have seen too many high-tech technologies, but when have you ever seen such a thing that is even more black technology than black technology?

Everyone was stunned.:.../

Lin Zheng's expression was very calm, not affected by the warm applause in front of him, and continued: "I believe everyone has noticed that the aircraft can make corresponding adjustments on its own to maintain the balance of the pole. How did the algorithm we designed to do this? Because we added a mathematical model of the pole to the aircraft. As long as we have a model system that mixes the aircraft and the pole, we can use the control theory to create algorithms to control it. Everyone see, with the support of the aircraft, the state of the pole is stable. Even if I push it gently, the aircraft can still help the pole maintain a balanced state."

As he said that, Lin Zheng stretched out his index finger and gently tapped the "teacher" and the balance affected "teacher" shook for a while, but soon, the drone acting as a "base" below quickly adjusted his posture in the air, and then maintained the balance of the entire system again.

“Wow…”

Not only did they open their eyes unconsciously, everyone who was completely attracted by Lin Zheng's explanation made a loud amaze: It's so awesome!

But do you think this is all? The naive child! After pursing his lips, Lin Zheng continued: "But of course this is not all. We can also increase the model to include the location where we want the aircraft to be, and use this to understand the reflection sign..."

As he said that, Lin Zheng picked up a control stick from the small table that looked a bit like a police T-shaped stick, but had several balls of different colors on it.

The audience immediately understood that this thing that looked a bit like a police T-shaped stick was the reflection sign that Lin Zheng said was to let the drone understand, but... what's the use of this thing?

Soon, everyone knew what this thing was useful.

"In this way, I can make the aircraft fixed in the space where I want it to be fixed." As he said that, Lin Zheng slightly raised the control rod. With Lin Zheng's movement, the drone immediately climbed lightly with the "teacher stick". And as Lin Zheng gently swayed the control rod left and right, the drone pressed the "teacher stick" immediately swayed left and right like a swing. The angle of the left and right shaking amplitude even exceeded 90 degrees. A magical scene appeared again: even with such a large swing amplitude, the drone could still maintain the balance of the "teacher stick" steadily. It did not let the "teacher stick" fall.

"Damn!"

"Damn it!!"

"Damn it!!!"

"I've gone against the sky."

"It's such a dog..."

Those who can participate in this technical discussion event, even if they are not experts, have some involvement in computer technologies such as automatic control, algorithms, logic and automatic control theories. The technical content contained in this action of this drone instantly shocked them. These people who want to describe their mood on weekdays can organize at least dozens of different words, and write articles at least 10,000 words. They have always used "elites", but can only use "dummy!", the two oldest and vivid words to express their inner excitement.

After Lin Zheng finished speaking, the request that he could not ask questions was immediately forgotten by these guys. The gentler ones knew to raise his hands, and the impatient ones simply called out. The host who was stunned by the silly host had to declare again that he would not accept any questions before Lin Zheng's demonstration ended.

The audience was definitely not satisfied. They had a lot of questions to ask Lin Zheng, but since Lin Zheng was unwilling to say it, they had no choice but to sit back again in disappointment.

Lin Zheng was very satisfied with the reactions of the audience below: Damn, if you can't scare you to pee, wouldn't the girl have been working so long in vain?

"The core of being able to achieve these clever arrangements of the aircraft is to use the algorithms and control theories designed by mathematical models. Let us tell the aircraft to come back and throw the pole..." With the movement of the control rod in Lin Zheng's hand, the drone shook and happily threw the pole on the ground: "Next I will demonstrate the value of understanding the physical model and the work of the world in the house... Well, dear, are you thirsty?"

Hum? What does this mean? Tan Na, who just sat down in the front row, was stunned for a moment, but then she smiled: "A little."

"This is a problem," Lin Zheng nodded seriously. He was a little distressed, "I have water here, but I can't go there in person, I have..."

As he said that, Lin Zheng picked up a transparent glass kettle from the small table and poured some water into a goblet. Then he placed the goblet on the drone suspended in front of him. The weight of the goblet and the water made the drone sink slightly, but soon it was balanced and kept floating.

After moving the control stick in his hand, Lin Zheng pointed the control stick at Tan Na's position, and the drone carrying the goblet flew lightly to Tan Na and stopped. Lin Zheng smiled and said, "Try it, it tastes pretty good."

Elegantly picked up the water cup from the drone and took a small sip, then placed the goblet on the drone, and happily said to Lin Zheng: "Thank you, my dear, you can drink some too."

She liked the little interaction Lin Zheng had played with her, and also enjoyed the feeling of announcing to everyone in public that she was very happy and that her couple was very loving... Well, to put it bluntly, women are born with the instinct to show their love.

Three black lines appeared on the head of the organizing committee: I know that you couple have a good relationship, but even if you have a good relationship, you won’t show it here, right? The foreigners in the hall cheered up warm applause. Foreigners who are naturally more enthusiastic in their personalities like Lin Zheng and Tan Na and their couple. Not only did they not think there was anything wrong, but many people gave Lin Zheng and Tan Na thumbs up.

After taking a sip, Lin Zheng smiled and said, "Thank you everyone, well, you may have noticed just now that when I put a glass of water on the aircraft, the aircraft had a sinking and losing altitude, rather than like the ones just now. Is it because the cup is heavier than the pole? Actually, it is not because I did not include this cup of water in the mathematical model system. In other words, the aircraft system does not know that the glass of water is on it, but it doesn't matter, we can tell the aircraft this..."

As he said that, Lin Zheng picked up the control stick that looked a bit like a police T-shaped stick again and said, "I want it to stay here... here... and here..."

As Lin Zheng's control rod continued to move, the drone holding a goblet kept changing its position and orientation in the air, just like a well-trained animal.

Warm applause sounded again, but this time, there were more people with bad looks again: I just thought that Lianchuang Technology's technology was already powerful enough, but now I realized that I still underestimated their strength, but this is not the most terrifying thing. What is the most terrifying thing is, where is their limit?

Your skills are so powerful, can you still have fun together in the future?

I feel uncomfortable? It's right. The expressions of those bad-looking guys made Lin Zheng feel much more comfortable, and his tone became lighter: "I wonder if you have asked yourself why the water in the cup has not spilled out? Lin Zheng just said that he had not established a mathematical model, and the aircraft did not know that the existence of this cup of water was two reasons. The first is the factor of gravity. Gravity affects everything. The cup and the aircraft are in the same direction; the second is that the propeller and the water cup point in the same direction: upward. Put these two reasons together, and the final result is that all the side forces on the cup are reduced and controlled by aerodynamics, and these are negligible for the movement speed of the aircraft. Look..."

So with the movement of the control stick in Lin Zheng's hand, the drone "pressed" the goblet on his head, and once again played the movements he had played when he was pressing the "teacher stick": he kept changing his position in the air, or swayed left and right like a swing, but just like he was pressing the "teacher stick", the water cup on the drone was still steadily, not falling off, and no drop of water in the cup was spilled out.

"This is why there is no need to model the cups. No matter what the aircraft are, they will not be separated."

Accompanied by the warmer applause, more and more people looked bad. Lin Zheng smiled and picked up the cup: "Sorry, I'm really a little thirsty after talking for so long. I'll drink a sip of water to moisten my throat."

Don't walk away, the next one will be more exciting. Everyone understands what Lin Zheng means.

But some people began to feel restless, yes, they were comrades from relevant departments.

Although they didn't know how powerful and technical the things Lin Zheng showed were, as long as they looked at the wide-open eyes of these foreigners, they could not transform into a camera and recorded everything they saw in detail. After they returned, they had to study how much dust was stained with Lin Zheng's shoes so that they could figure out whether the dust had any cooperation and influence with the display just now. They knew that the things Lin Zheng demonstrated contained amazing technology. But the question is, is it really good to show such advanced things to foreigners? Isn't there any danger of leaking secrets?

The country means that through this expo, Americans realize that they should not underestimate us and gain a favorable bargaining chip for our negotiations with the Americans. But now it seems that what Lin Zheng takes out is too scary?

Do you want to stop him? (To be continued.)
