At this time, no one complained about Lin Zheng's clothes, even the people in the organizing committee who were hiding in the background to watch Lin Zheng's speech also had a big mouth: relying on the advantages of organizing various exhibitions, they can be regarded as well-informed and have seen too much high-tech, but when have they ever seen this kind of thing that is even more black than black technology?

They all looked stupid. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info[ads:This site has a new URL,Shorthand method:,.]

Lin Zheng's expression was very indifferent, not affected by the warm applause in front of him in the slightest, and continued: "I believe you have noticed that the aircraft can take the initiative to make corresponding adjustments to maintain the balance of the pole, how did the algorithm we designed achieve this level?" Because we have 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, you see, with the support of the aircraft, the state of the pole is stable, even if I push it gently, the aircraft can still assist the pole to maintain a balanced state. ”

As he spoke, Lin Zheng stretched out his index finger and lightly tapped the "Teaching Whip", and the "Teaching Whip", whose balance had been affected, shook for a moment, but soon, the drone acting as the "base" below quickly adjusted its attitude in the air, and then re-maintained the balance of the entire system.

"Wow......"

Not only did their eyes widen unconsciously, but everyone who was completely attracted by Lin Zheng's explanation let out a loud exclamation in unison: It's amazing!

But you think that's all there is to it? Naive child! Pursing his lips, Lin Zheng continued: "But of course this is not all, we can also enlarge the model so that it includes the position where we want the aircraft to be, and use this to understand the reflection marker......"

As he spoke, Lin Zheng once again picked up a control stick that looked a little like a police T-stick, but there were several round balls of different colors on it.

The audience understood immediately. This is a bit like a police T-stick, which is the reflective mark that Lin Zheng said the drone could understand, but ...... What's the use of this thing?

Soon, everyone knew what this thing was for.

"That way, I can get the craft to be fixed in space where I want it to be." As he spoke, Lin Zheng raised the control stick slightly, accompanied by Lin Zheng's action. The drone immediately climbed lightly against the "whip", and with Lin Zheng gently shaking the control rod left and right, the drone with the "whip" immediately shook left and right as a swing, and the angle of the left and right shaking amplitude even exceeded 90 degrees, and the magical scene appeared again: even with such a large swing amplitude, the drone was still able to maintain the balance of the "whip" steadily, and did not let the "whip" fall.

"it!"

"it!!"

"Groove !!"

"It's against the sky."

"It's really a dog......"

Even if they are not experts who can participate in this technical discussion activity, they are also involved in computer technology and automatic control theories such as automatic control, algorithms, and logic, and the technical content contained in this action of this drone instantly shocked them. These guys who want to describe their mood on weekdays can organize at least dozens of different words, write articles with at least 10,000 words, and have always been "elites", but at the moment they can only use "slot!" These two oldest and most vivid words to express the emotions in your heart.

Before Lin Zheng finished speaking, the request not to ask questions was immediately forgotten by these guys. Sven still knew how to raise his hand, but the anxious one had simply shouted out, forcing the dumbfounded host to reaffirm that he would not accept any questions until Lin Zheng's presentation was over.

The audience was certainly not satisfied. They had a stomach full of questions that they wanted to ask Lin Zheng, but since Lin Zheng didn't want to say it, they had no choice but to sit back again.

Lin Zheng was very satisfied with the reaction of the audience below:, if you can't scare you into peeing your crotch, hasn't the girl been busy for so long in vain?

"The core of being able to achieve these clever maneuvers on the aircraft is the algorithms and control theories designed using mathematical models. Come, let's tell the aircraft to come back and drop the pole ......" accompanied by the movement of the control stick in Lin Zheng's hand. This time, the drone shook and happily dropped the pole on the ground: "Next, I will demonstrate the value of understanding the physical model and working in the world in the house...... Well, dear. Are you thirsty? ”

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

"That's a problem." Lin Zheng nodded solemnly, a little distressed, "I have water here." But I couldn't go there myself, with ......"

As he spoke, Lin Zheng picked up a transparent glass kettle from the small table, poured some water into a goblet, and then put the goblet on the drone suspended in front of him, the weight of the goblet and water made the drone sink down slightly, but it quickly regained its balance and kept it suspended.

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 in front of Tan Na and stopped. Lin Zheng smiled and said, "Taste it, it tastes good." ”

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

She liked the little interaction that Lin Zheng played with her, and she also enjoyed the feeling of announcing to everyone that she was very happy and that she was very affectionate in front of everyone...... Well, to put it bluntly, women are born with the instinct to show affection.

Three black lines popped up in the heads of the organizing committee: I know that the two of you have a good relationship, but even if you have a good relationship, you won't show off here, right? However, the foreigners in the hall applauded warmly, and the foreigners who were naturally more enthusiastic and outgoing preferred the character of Lin Zheng and Tan Na, not only did they not feel that there was anything wrong, but many people gave Lin Zheng and Tan Na a high thumbs up.

After taking the same sip, Lin Zheng said with a smile: "Thank you, well, you may have noticed just now, when I put a glass of water on the aircraft, the aircraft has a sinking and losing altitude, not like the root just now, is it because the cup is heavier than the pole?" Actually, it's not, because I didn't include this glass of water in the mathematical model system, that is, the system of the aircraft doesn't know that the glass of water is on it, but it doesn't matter, we can tell the aircraft about it......"

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

With the continuous movement of the control stick in Lin Zheng's hand, the drone with the goblet on its top kept changing its position and direction in the air, just like a well-trained animal.

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

Your skills are so good, will you be able to play happily together in the future?

Feeling sick? It's right to feel uncomfortable, the expressions of those unsightly old men made Lin Zheng's heart feel a lot more comfortable, and his tone became more and more brisk: "I don't know if you have ever asked yourself, why didn't the water in the cup spill out?" You Lin Zheng just said that there is no mathematical model, and the flying machine does not know the existence of this glass of water, there are two reasons, the first is the factor of gravity, gravity affects everything, and the cup and the aircraft are in the same direction; The second reason is that both the propeller and the water cup are pointing in the same direction: upwards. Putting these two reasons together, the end result is that all the lateral forces on the cup are aerodynamically reduced and controlled, and these are negligible for the speed of the aircraft moving, you see......"

So with the action of the control stick in Lin Zheng's hand, the drone "topped" the goblet on its head, and once again played the actions that he had just played when he was holding the "whip": constantly changing its position in the air, or shaking left and right as a swing, but just like the "whip" just now, the water cup on the drone was still stable, did not fall, and the water in the cup did not spill a drop.

"That's why you don't have to model the cups, they don't separate in the first place, no matter what happens to the aircraft."

With more enthusiastic applause, there were more and more people with unsightly faces, and Lin Zheng picked up the cup with a smile: "I'm sorry everyone, I'm really a little thirsty after talking for so long, I'll drink saliva to moisten my throat first." ”

Don't go away, there's more to come. Everyone understands the meaning of Lin Zheng's words.

But someone began to fidget, yes, comrades from the relevant departments.

Although they don't know how powerful and high-tech these things Lin Zheng is showing, as long as they look at the round eyes of these foreigners, they can't turn into a video camera, record everything they see in detail, and even study how much dust is on Lin Zheng's shoes after they go back, so as to figure out whether these dusts are compatible with and affect the display just now, they know that these things demonstrated by Lin Zheng contain great technology. But the question is, is it really good to show such an advanced thing to foreigners? Isn't there a danger of leaks?

The state means to make the Americans realize that they should not underestimate us through this expo and strive for a favorable bargaining chip for our negotiations with the Americans, but now it seems that what Lin Zheng has come up with is too scary?

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