this narration is wrong

Often big things in this world are not so smart.

就拿大象来说，作为世界上最大的陆生动物，亚洲象肩高2至4米，体重3至5吨。非洲象肩高3至4米，体重5.5至8吨。非洲森林象平均肩高不超过2.7米，体重3.5吨。

With such a large size, the flexibility of elephants is actually very low compared to other animals.

Small animals such as cats and dogs can get up no matter how many times they fall, but elephants often suffer fatal injuries once they fall.

Moreover, the elephant's limbs are also very clumsy. Only the trunk is more flexible in the whole body.

The same goes for a robotic arm. Guo Yuan now wants to improve the response speed and sensitivity of the robotic arm as much as possible.

Because the ultimate goal of the robotic arm is to regenerate severed limbs.

If possible, Guo Yuan even wants to incorporate the external robotic arm into this large system of the human body.

In fact, the human body itself is a system. Human beings issue instructions through the brain and nervous system, and then transmit them to the target muscle groups. The muscles of the muscle groups contract or stretch, and then the human limbs will move.

This intermediate time is exactly the human reaction time. Science has proven that the limit of human reaction speed is 1 milliseconds, which is 00 seconds.

In fact, if the response time of the robotic arm can reach 0.1 seconds, then Guo Yuan will be very satisfied.

Unfortunately, the current response speed of the robotic arm is about 0.3 seconds to 0.4 seconds.

If the room-temperature superconducting material that made a lot of noise on the Internet last year is true, Guo Yuan does not need to think about how to achieve a response speed of 0.1 seconds. He only needs to replace this material on the line and everything will be fine.

It may be false, so Guo Yuan had to think about the time-consuming data of the execution transmission and power system start, hoping to find the point where he broke the game, and then optimize the response sensitivity of the robotic arm.

The response speed of the motor is definitely greater than the response speed of the hydraulic system, but the upper limit of the power provided by the motor is relatively small.

After thinking for a while, Guo Yuan suddenly felt that the problem he should probably think about and solve was how to increase the upper limit of the power provided by the motor. As for shortening the response time of the hydraulic system, that was not a promising path.

The application of electricity will only become more widespread in the future, and the path of electric motors will be more promising, and it will also help simplify the structure of the robotic arm.

Thinking of this, Guo Yuan took a look at the existing design of the robotic arm. After reviewing all the previous design drawings of the robotic arm, Guo Yuan confirmed that this idea is indeed feasible.

After clarifying the goal, Guo Yuan immediately woke up 01: "01."

"I'm here, what's Mr. Guo Yuan's order?"

"01, help me collect detailed information on high-power servo motors."

"Okay, Mr. Guo Yuan, the data is being collected. The data has been collected and has been transferred to your computer. Do you want to open it?"

"Open."

As soon as Guo Yuan finished speaking, he saw a new folder on the desktop, which was opened by 01.

Guo Yuan roughly browsed through the information and documents in the folder.

The content here contains detailed information on the best-performing motors on the market. Even some of the information in the folder can be clearly seen as internal information of a certain company. These information files clearly indicate that they are still in the research stage.

This is the great thing about 01. He can get all the information he wants without anyone noticing. The Internet has no secrets for 01.

After reading it, Guo Yuan said: "01, eliminate relevant domestic patents."

"Good Mr. Guo Yuan."

With Guo Yuan's order, 01 deleted the domestic patents in the folder.

Guo Yuan is very willing to use the convenience that 01 brings to him.

But Guo Yuan would not directly use the domestic means of production.

Just imagine, if 01 directly hacks into the R&D database of a certain company, and then applies for a patent or releases a product one step ahead of time, then the corresponding company's early R&D investment will be in vain, and the company may even go bankrupt as a result.

It is his compatriots who are being deceived by such things happening in China, and Guo Yuan will definitely not do this.

There is no psychological burden abroad, and Guo Yuan doesn't care at all about the life and death of foreigners.

Guo Yuan then continued to look through the remaining information in the folder.

Soon Guo Yuan found a more suitable one among the many documents. From the company name on the document, Guo Yuan could tell that it was a German company.

01 specially translated the information and presented it to Guo Yuan in Chinese.

After reading this information from beginning to end several times, Guo Yuan had an idea.

"01, create a 3D model based on this information."

"Good Mr. Guo Yuan."

A few minutes later, a 3D model of a motor appeared on the screen. Guo Yuan asked 01 to modify and adjust the model according to his own ideas.

With the help of 01's super computing power, Guo Yuan is confident to design and manufacture a motor that meets the needs of his robotic arm.

In the next week, Guo Yuan has been busy with the motor. With the help of 01, Guo Yuan used that information as a blueprint and reconstructed it hundreds of times, and finally got a motor that met his requirements.

Now it’s time to produce this motor and see the specific effects.

Guo Yuan thought about it and handed the task over to the robotic arm company invested by Future Technology. After Zhou Songfeng got the design drawing of the motor, he just glanced at it and couldn't look away.

"Boss here."

"Don't ask too many questions, just build the thing first."

"Okay." Zhou Songfeng nodded and went to work.

Two days later, Guo Yuan got two motors.

The internal structure of these two motors is exactly the same, but the volume is different.

One is the size of a small generator, the other is about the size of an adult fist.

"Can't we shrink any more?"

"No, boss, this is already our limit. Our machine tools can only reach this level. If we want to continue to shrink, we must either buy the most advanced production machine tools from Germany or the United States, or ask Help from above.”

"That's it! Have you tested the performance?"

"After testing, the energy conversion rate of this motor is incredibly high. The upper limit of the power it provides is three times that of the most advanced motor of the same size in Germany. This is because our accuracy is not enough. If the accuracy can be improved, It should be more than three times."

Guo Yuan nodded with satisfaction.Guo Yuan returned to the company with two motors. He thought about it and decided to go to the satellite launch center in Bingzhou for help. There should be machine tools with higher precision there.

It's just that Guo Yuan didn't want outsiders to see this motor, so Guo Yuan asked Cheng Shuqing to arrange the company's private jet. He wanted to fly back to Bingzhou on the private jet.

The next day, Guo Yuan and Cheng Shuqing sat on the private plane together.

Those two motors were also put on the plane.

Guo Yuan rarely travels by private plane. This plane belonging to Guo Yuan is usually used more by other senior executives of the company.

Being so anxious to take a private plane back to Bingzhou this time, Cheng Shuqing knew immediately that there must be something more important.

At 10:[-] in the morning, the plane took off.

When the plane flew for about an hour, Cheng Shuqing suddenly heard an exclamation: "Boss, look outside! What is that!"

Upon hearing this, Guo Yuan immediately lowered his body and looked out the window.

Guo Yuan turned around and saw what Cheng Shuqing said.

In the sky not far away, a series of fireballs were sliding down from the sky. These fireballs dragged long tail flames and looked like meteors, flying quickly in the sky above the clouds.

"Old boss, what do you think this could be? Aliens? Or another plane crashed in an accident? Or missile debris or something?"

Cheng Shuqing's face turned pale because of nervousness.

These fireballs looked really close to them, as if they were going to hit their plane at any moment.

Once a vehicle like an airplane crashes, the probability of survival is infinitely close to 0. Basically, it means death.

It is understandable that Cheng Shuqing would be nervous.

To be honest, Guo Yuan was also a little nervous. Fortunately, the narrator spoke at this time:

[This is the wreckage of the launch vehicle, please don't be nervous. 】

Guo Yuan breathed a sigh of relief when he heard this. He quickly comforted him softly: "Shu Qing, don't be nervous. I guess it was a satellite or rocket that fell. It's definitely not something bad. This is in China's airspace. Don't worry, our flight is safe." ,do not be afraid."

As soon as Guo Yuan finished speaking, a middle-aged man came over led by the stewardess.

"Mr. Guo, Secretary Cheng, this is Captain Sun of our plane." the stewardess introduced.

"Hello, Captain Sun."

"Hello, Mr. Guo! Mr. Guo, we have also noticed the abnormality outside the cabin. We have just made contact with the ground and have determined the cause of the abnormality."

Hearing the captain's words, Cheng Shuqing's face turned rosy. If the captain came over to explain, it means that there is a high probability that everything is fine. Otherwise, the captain should be thinking about solving the problem now instead of coming here to talk nonsense.

"Mr. Guo, we have determined that the external abnormality is due to a rocket launch mission at a certain launch site today. The external fireball is the flame generated by the rocket body sliding from outer space and friction with the atmosphere."

After Cheng Shuqing heard the captain's explanation, she relaxed completely. She glanced at Guo Yuan and thought: "The boss was right."

"Is this rocket launch very close to us?" Cheng Shuqing asked.

"Not close, not close at all. Our country has strict regulations on the location and time of rocket launches. It is impossible to collide with civil airliners. The vision we see through the porthole is actually very far away from us and will not affect The flight of this flight is safe. Please rest assured, Secretary Cheng."

"Then why am I looking so close?"

"This is because there is no obstruction and smoke above the clouds, plus the height of the aircraft, so we can see very far away. The area where the rocket body fell is not in our flight path."

"The captain is right, Secretary Cheng, I have been flying in the sky for almost three years, and this is the second time I have encountered this situation.

Mr. Guo and Secretary Cheng should be happy to meet each other. Being able to observe the rocket body falling is a very rare experience and a very lucky thing.

Maybe after the plane lands, Mr. Guo and Secretary Cheng can buy a lottery ticket and win the prize! "

Hearing what the stewardess said, Cheng Shuqing was completely relaxed.

After the flight attendant and the captain left, Cheng Shuqing took out her mobile phone and took a few photos to record this rare moment.

Guo Yuan leaned over to watch Cheng Shuqing take photos. He had never encountered such a situation before and was very curious. However, Guo Yuan did not have to take photos himself. 01 would borrow professional equipment on the plane to take good photos for him.

But it looks good, and Guo Yuan doesn't care too much about this kind of picture, because to put it bluntly, it's just a launch vehicle.

The launch vehicles currently developed by various countries and organizations are multi-stage rockets, which are determined by chemical fuel combustion specific impulse and engine thrust.

The first and second stages of the launch vehicle will basically turn off their engines after completing their respective tasks. The speed of the rocket body will slowly decrease in the friction with the thin atmosphere until it cannot maintain a certain speed level, and finally it will naturally fall back to the ground.

The speed of the rocket when it falls into the atmosphere is extremely high, which can reach 1300 meters per second, and sometimes even higher. The friction between this speed and the dense atmosphere will produce a high temperature of more than 3000 degrees. Even at such a temperature, The metal rocket body will also be ablated, and then the scene we see now will appear, turning into a fireball falling from the sky.

Of course, not all rockets will have debris.

Such problems do not occur with recycled first-stage rocket bodies, such as Musk's Falcon 9.

Because the Falcon 9's first-stage rocket body will restart the bottom engine to decelerate when it re-enters the atmosphere, reducing the speed to a safe level. In this way, the friction between the rocket body and the atmosphere will be reduced, and the high temperature generated by the friction will be reduced. Naturally, it will also be reduced, thereby ensuring the integrity of the rocket body.

"Boss, aren't you excited at all?"

"What's so exciting?" Guo Yuan asked back.

"The flight attendant just said that she has only encountered this once in three years of working as a flight attendant. This kind of thing has happened to us, which shows that we are very lucky!"

"What if the stewardess is just afraid that we will be in a bad mood when we encounter this kind of thing, and anger them, and make up nonsense?"

"Is that impossible?"

"Even if it's true, it's just the wreckage of a rocket launch. It's not worth your excitement. In a few years, your boss will start a commercial aerospace business and take you to watch rocket launches every day."

Cheng Shuqing still had a smile on her face when she heard this, but she was already complaining in her heart. How could the boss be so confident about this even though he didn't even mention it?

Cheng Shuqing really doesn't think that a commercial aerospace company with future technology will be able to do it.

Of course, as a secretary, Cheng Shuqing would definitely not say this in front of Guo Yuan.

But Cheng Shuqing didn't know that her inner thoughts had been fed back to Guo Yuan by the narrator.

However, Guo Yuan doesn't care about this. Normally, everyone thinks that Guo Yuan's commercial aerospace company crossover this time is a bit too big.

These days, most of the people who are doing cross-border business are young and old who are speculators. It is normal for Cheng Shuqing not to believe that this company can succeed. If Guo Yuan hadn't been involved, he wouldn't have dared to make such a fuss. (End of chapter)
