Chapter 1230: Techniques to Fear the Dead: Up
Lin Zheng didn't care if these foreigners suddenly had a brain twitch, and he didn't even say the simplest opening sentence: "an", he came up and went directly to the main body: with his move, on the white curtain specially laid on the ground, so that everyone didn't know what it was for, one of the two four-axis electric drones slowly flew up, and after turning lightly in the air, it slowly suspended in front of Lin Zheng.

Many people were stunned in their hearts, looking at these two drones before, they muttered a little in their hearts, thinking that these two drones were used for live demonstration, but now it seems that they guessed half right, these two drones are indeed used for live demonstration, but the demonstration is very different from what they think.
"What does it mean to have someone who has the same athletic ability as an athlete?" Lin Zheng's first sentence after the official start made everyone's mouths closed in surprise: "I want to use this quadcopter drone to demonstrate the concept of machine movement ability to everyone, and study and prove our theory, which we call simply an aircraft." ”
As he spoke, Lin Zheng took the quadcopter suspended in front of him in his hand, and continued: "This kind of structure of the aircraft has been around for a long time, but to put it mildly, it is carried forward by our Lianchuang Technology, and the 4-axis, 6-axis and 8-axis unmanned aerial vehicles jointly produced by Lianchuang Technology and Fengshang Technology have become the preferred aerial photography equipment in the domestic media industry and film and television production industry...... Well, it's kind of an advertisement for us. ”
There was a burst of good-natured laughter below, and Lin Zheng said that it was humorous and funny, not only did it not make people feel disgusted, but it was quite interesting, but in the same way, some people's brows furrowed: It seems that Lianchuang Technology started on drones and intelligent drones much earlier than he thought.
This is not good news.
Lin Zheng was also laughing. After laughing, Lin Zheng continued: "Of course, the reason why this kind of flying machine is so popular. Because of their simple construction, they don't look like traditional fuel-powered model airplanes. It requires a complex transmission structure and skilled manipulation skills to be able to control proficiently, the control of fuel powered helicopter model aircraft is the patent of the 'old birds', every 'old bird' who can skillfully operate the fuel helicopter model aircraft is the object of worship of people in the circle, but this kind of aircraft is different, they do not have a complex mechanical structure, just by controlling the speed of the four propellers, you can make this aircraft roll, tilt, shake and accelerate in their common direction, and the battery is placed on the deck in the center of the aircraft. Microcomputer control chips, various sensors and radio signal transceiver devices. These aircraft are very sensitive, but this sensitivity comes from our efforts, because they are not inherently stable, so they need to be able to automatically feedback and adjust the system to be able to fly ...... steadily."
As he spoke, Lin Zheng threw the quadcopter drone in his hand forward.
The audience suddenly exclaimed, everyone thought that the drone was going to break, but the next moment, under the eyes of everyone, a surprising scene appeared: the drone was just thrown out by inertia for a distance, and then automatically flew back in front of Lin Zheng. Suspended in front of Lin Zheng as he did just now.
It's not like someone is remotely manipulating...... The person who was still wondering if someone was hiding on the side to remotely operate this drone couldn't help but mutter.
So, I believe everyone has a question in their minds. How on earth does it do all this? Leaning the top of the drone towards everyone, Lin Zheng pointed to the aircraft and the arranged venue and said: "The camera and microcomputer on the top of the aircraft provide a full positioning system in the lecture hall to locate the objects that have been reflected in the space, and these data are sent to another computer running measurement and control algorithms, and then send instructions to the aircraft in turn." At the same time, the vehicle also runs measurement and control algorithms......"
As he spoke, Lin Zheng threw the drone out again.
This time, no one exclaimed, and the guests sitting in the front seat did not exclaim as they did when Lin Zheng threw the drone out for the first time just now: they had already determined that the drone would not be smashed on their heads.
The fact is that the plane really didn't hit their heads. As just now, he continued to levitate in front of Lin Zheng.
"Most of our research is algorithms. Essentially, it's algorithms that magically give life to these machines. To make them look like living creatures, how do you design algorithms to give machines the ability to move? Seeing someone raise their hands and want to ask questions, Lin Zheng said with a smile: "Everyone, I believe that Mr. Host has announced some precautions for this event just now, it is time for my show, and the questions will start after my show is over." ”
The one who raised his hand to ask a question retracted his hand in embarrassment: The host did say before that he didn't accept questions before Lin Zheng's demonstration was completed, why did he forget it? Apologetically, he said, "I'm sorry. ”
"It's okay," Boss Lin generously forgave the reckless old man, and then continued: "Here, we use some designs called model foundations, we first use mathematical models that capture the physical behavior of machinery, and then, we use mathematical branches...... It's called Control Theory...... To analyze these models, and then to synthesize the algorithms that control the aircraft, for example, this is how we levitate the aircraft, first, we use a whole set of different equations to capture the dynamical state, and then we manipulate those equations with the help of control theory to create algorithms that stabilize the aircraft. ”
Looking at the audience below who seemed to be a little puzzled, Lin Zheng's heart moved slightly, and said, "Next, let me show the power of this method......
As he spoke, he turned around and picked up a slender whip-like thing from the small table on the side, but unlike the whip, at the top of the "whip", there was a ball slightly smaller than a ping pong ball.
Seeing this ball, the audience involuntarily sat up straight: they were keenly aware that the show had really begun to play.
It's time for the show to come.
Holding the "teaching whip" and walking back in front of the drone, Lin Zheng said: "Suppose we not only want this aircraft to be suspended in the air, but also to support this pole in a balanced way...... Of course, it's simple for us humans......"
While speaking, Lin Zheng put this "teaching whip" in the left hand of the tree, holding it with the palm of his hand, and gently shaking the palm from side to side to assist the "teaching whip" to maintain balance.
"We humans have the advantage that we have two feet on the ground, and by using our very nimble, almost omnipotent hands, we can easily do that, but when we only have one foot on the ground and we can't use our feet...... Thinking about it now, it's a little difficult now. ”
Saying that, Lin Zheng raised his left foot and put the "whip" on the surface of his raised left foot vertically, the result is naturally conceivable, the flexibility of the foot is obviously not comparable to the hand, although Lin Zheng tried very hard to keep the "whip" upright, but in just a few seconds, the "whip" could not maintain balance and fell to the ground.
There was a burst of laughter at the scene again, and at the same time, everyone's enthusiasm and attention were completely attracted by this fresh and interesting way: compared with the traditional form of the report meeting, Lin Zheng's activity was not only unique enough, but also vivid enough.
Those who reacted quickly already understood what Lin Zheng wanted to do, and they were immediately taken aback: Could it be that Lin Zheng wanted to use drones to maintain the vertical state of this "whip" relative to the ground?
As soon as this thought came to mind, it suddenly made the spirit shudder: how is this possible?! How is it possible for a drone suspended in the air to this extent?!
But although he knew that it was impossible, he subconsciously stared at Lin Zheng's every move: if the drone can really do this action, the information contained in it is too amazing.
"As you can see, there is a ball at the top of the pole, which is a reflective sign, that is, it can be located in space," said Lin Zheng, who came to the drone that had been in a suspended state, and the drone slowly descended in height as if it had eyes......
The real drama is here!
Everyone in the conference room invariably widened their eyes, could this drone really keep this "whip" vertical and not fall crooked?
Those experts who understood the significance of this action covered their chests nervously, and their faces turned white: If Lianchuang Technology really has this kind of technology, it will be too scary.
A scary scene appeared, when Lin Zheng carefully put the lower end of the "whip" on the drone, the drone really held the "whip", so that the "whip" was in a vertical state relative to the ground, and just like Lin Zheng just used his hand to hold the "whip" when he gently shook the relative position of his palm in the space to keep the vertical state of the "whip" stable, the drone was also gently shaking itself to ensure the state of the "whip", what is even more creepy is that The amplitude of the drone's shaking is much smaller than the amplitude of Lin Zheng's palm, and the amplitude of the "teaching whip" shaking in the air is also much smaller than the shaking amplitude in Lin Zheng's hand......
Seeing this scene, the audience below could no longer control their vocal cords and slaps, and screamed in unison, and the applause sounded like thunder...... (To be continued)
