Chinese entertainment for engineering students

"Tell me about it, don't make me read it from the beginning." Professor Yan had a headache looking at the pile in front of him. This student is really a genius. Reading what he writes is sometimes a kind of torture, so it's better to listen to what he writes. The song is comfortable.

"Well, it can be roughly divided into several directions. In fact, I can't even understand it. I'm not as good as you. But Wang Xu has divided it into categories from the beginning. Just look at the cover.

You see, this pile is for you to focus on, about robots. He said that there are some achievements in servo motors, but the accuracy has not yet been achieved, and it has not yet been mass-produced, so it has to wait, but if you are willing to spend money, it is not impossible to buy one, and it does not need to be so precise in the beginning.

And the robot chip has to wait, but the algorithm can be advanced first. He mentioned several types, such as multi-axis robotic arms, suspended mechanical platforms, two-wheel self-balancing platforms, four-legged platforms, bipedal walking platforms, etc. , there are even water platforms and flying platforms.

He said that these things should be of interest to you. You can pick two to study and leave a few for the Chinese Academy of Sciences and Harbin Institute of Technology. They had greeted Wang Xu last time.

In fact, you already have the core of the algorithm. Professor Luo is an expert. He has already done it quite deeply, but his computing power cannot keep up.

Now you can drag a bunch of lines and use the computing power of the server. Later, when high-level chips are available, you can then find a way to reduce the size. Let’s first check whether they are available. "Director Jiang explained it in detail.

"Does he have any suggestions?" Professor Yan knew Wang Xu very well. This guy was not completely impartial. Instead of thinking about it on his own, it was better to listen to him.

"His suggestion is that if you want to create a gimmick, then go for a bipedal one. If you want to get some results quickly, then go for the robot dog first, which is a four-legged platform. Leave the rest depending on what you like. Share everything that comes down." Director Jiang repeated Wang Xu's words. This is Wang Xu's natal home and his base camp. He is here to help him look after the house.

Wang Xu had already introduced the plan of his laboratory to him. In the early stage, he focused on three aspects: basic theory of artificial intelligence, numerical control automation and four-axis drones. Professor Luo was mainly responsible for the work on artificial intelligence.

The research on basic numerical control algorithms is still waiting for researchers to report on it. The department has recently recruited a doctor who studied abroad and graduated from MIT, but he will not be available until the end of the year.

The research on the four-axis flight algorithm is in cooperation with the Imperial Aviation Academy, so the current laboratory here is mainly used by Professor Luo. It is more like a computer room than a laboratory.

"Okay, hey, let's just pick first. What else is there?" Professor Yan felt a bit like Li Yunlong, who couldn't move when he saw good things. Oh, by the way, this movie hasn’t been shot yet.

"There is also the Yuntai project. Do you want to get involved? Yuzhuo said I don't know if I should trouble you. This is Wang Xu's sole investment. It is probably an investment and commissioned development model. It should not be open source, nor The profits are divided and used on drones, and he uses them to make movies."

"What's the trouble with this, gimbal? It's that kind of self-stabilizing platform, right? I think I heard him mention it. This thing is not difficult. Now he has laid all the foundations, except for the control chip. It's easy to do, and everything else is fine.

I guess he is also waiting for the supercomputer chipset, and leaves the rest to us.

It's much better to help this guy make money than to help others. Can the paper be published? "Professor Yan is quite interesting. He knows that Wang Xu sometimes works on some projects for his own use, and he also knows that they have cooperated with Imperial University of Technology on some small projects.

"There is definitely nothing wrong with the paper, but these things are not internationally leading. I don't know what to publish, and I don't know much about it.

It seems that papers have been published on algorithms and so on, and they all seem to be open source. "Director Jiang understands Wang Xu's habits, and the paper can definitely be published.

"I know the algorithm. There are open source projects, but it's still different. That one is automatic control of multi-links. This one is a little more complicated." When it comes to this, Professor Yan is an expert.

The multi-link thing was also developed by Wang Xu. It is a dynamic balance system that is put into the open source community for everyone to play with. The current open source version can already keep three connecting rods from falling over.

This thing was also done by Shuimu. The graduation thesis of a certain doctor had little to do with Wang Xu. On the contrary, this direction was the idea that Wang Xu helped come up with.

"I don't know. If you want to do it, just stay. It's a lot of money. Wang Xu has invested hundreds of thousands." Director Jiang pulled out a stack of information and handed it to Professor Yan.

"What does he plan to do with this thing? You didn't report it to the police?" Professor Yan was very surprised. He could see the effect of this thing. Adding a few more degrees of freedom would allow him to control too many things.

Even if it is not increased, the launching platform of the small flying stick can be changed to a follow-up one.

"I have reported it to you a long time ago. When you come up with it, you will be given bonuses by the superiors. Now it has been established as a system. It has not yet been written down. However, the superiors have also discovered the benefits of military-civilian integration and plan to reform it."

"Let me just say, there is no reason why the higher-ups don't know."

"Now the main thing is to develop the economy. When we get new things, most of them are saved first. I have made many new things with the things you provided, but it is too expensive and still too poor." Director Jiang said with emotion, unlike Ivory Professor Yan in the tower obviously knows more about the country's situation.

"I'm not a military fan, and I don't know much about it. I just heard Wang Xu say a lot. This guy is a complete military fan, and everything can be related to military struggles." Professor Yan was honest and admitted directly. Little is known about this aspect.

"Oh? Tell me, what did he talk about?" Director Jiang is interested in everything Wang Xu says and does. This kid can sometimes see trends based on very small things, and this kind of grasp of trends It is the so-called strategic sensitivity that is extremely important in the military.

Of course, if Wang Xu were here, he would definitely be speechless. If he was sensitive, it would be based on the future.

"It's not a lot. Just wait. I'll look for it. I've also memorized a lot of conversations with Wang Xu. You know, I'm over 40 and my brain isn't that easy to use anymore. I often finish talking to him. I will go back and sort it out." Professor Yan took out a notebook and explained while flipping through it.

This is the habit of people in this era, especially intellectuals, to carry a pen and a notebook with them. The pen stuck in the chest pocket was once still a label for intellectuals.

Until many years later in the Internet age, many old people still retain this habit. No matter how convenient their mobile phones are, they still retain the habit of recording with pens.

Of course, there are also many formalistic stories derived from this, such as a writer criticizing the bizarre incident of recording a leader reading the original text of a document at a meeting.

"Look, a four-axis drone is an artifact of future guerrilla warfare. I don't quite understand what artifact he is talking about, but it is probably an important weapon." Professor Yan turned to a certain page and pointed to his own records and Jiang The director said.

He is very humble, but he is actually very sensitive, otherwise he would not have recorded such a casual remark.

"Is the four-axis aircraft so important, or is it guerrilla warfare?" Director Jiang was also a little confused. The four-axis aircraft has low energy consumption, slow speed, low altitude, and cannot carry heavy weapons. The key is that the price is not cheap at all.

It is said that Wang Xu spent millions on a four-axis aircraft, and it could only fly for ten minutes with a load of more than ten kilograms, and it could not exceed one kilometer. That is why he dared to do so.

"Well, you see, that's what he said at the time.

This thing can cost a few hundred yuan each, transmit images for three kilometers, carry half a kilogram of explosives in it, fly directly around obstacles, and fly over to blow up the soldiers and equipment in the bunker. It is no more useful than a sniper rifle.

If there was a turret or something like that, you could fly in directly from the window. If you had this during the Anti-Japanese War, you would have been able to fight until the end of the day.

Haha, that's what he said at the time. You said he hasn't been through that era, so why is he so obsessed with it? "Professor Yan recalled the conversation with Wang Xu at that time, and it was quite interesting when he thought about it.

That was when Wang Xu was cooperating with the Automation Department and the Aviation Academy. When I talked to him afterwards, he didn't mention the use of the four-axis at that time, but only mentioned the camera base used for shooting movies.

The development of this thing was purely for civilian use. Regardless of the purpose or means, it was all done by the private sector. However, when they returned to Shuimu together, Wang Xu and Professor Yan mentioned it while eating together, and Professor Yan took note of it.

"It's such a big plane, and it's so slow. Why can't it be shot down immediately?" Director Jiang hadn't figured out how to use that thing yet.

"It doesn't need to be that big. He said that after chip technology develops in two years, this thing will be about the same size as the palm of your hand. The reason it is so big now is because the computer power required for complex flight control is too high.

He had to use almost all the main chips in the workstation to barely have enough power, and he also had to bring more batteries to power the flight control system. In addition, he needed to support a large camera, so it was naturally quite large.

I don’t know much about airplanes, but I still know about chips. They can be halved in size in a year, and their performance can be doubled. Soon, a chip the size of a thumb will be enough. "Professor Yan looked at his notebook and continued to explain. Obviously, he recorded it in quite detail.

"Really, we may all underestimate how important the progress brought by the development of electronic technology is. Everything on the aircraft affects the whole body. The smaller the computing unit, the smaller the power supply.

Therefore, the required load will be smaller, and then there will be no need for such a large motor, and the battery can be small. All things considered, the lightness may not be as much as the weight of the chip. "Director Jiang sighed, he is not a professional military engineer.

It’s only recently that I have followed Wang Xu, listened to more and more things, and had to learn more things myself, and now I have become more knowledgeable.

It seems that Wang Xu's remarks need to be remembered in more detail. Let's go back and make a report. Let's get bodyguards for him and his wife.

"Can I borrow this book of yours to read?" Director Jiang asked politely.

"Why do you think I mentioned this matter? Make a copy and return it to me." Professor Yan handed the notebook over with a smile, then picked up the teacup and watched Director Jiang hurriedly looking for someone to make copies.

He continued to look through the materials in front of him.

As Director Jiang introduced, these materials are quite complicated, and many of them are just one page. Professor Yan has not seen this kind of information rarely. These are all projects that Wang Xu suddenly thought of, and often require more research to get results. .

In the past, everyone was grabbing the thick ones with detailed plans and routes. Later, there were not enough professors. After all, it was stipulated that one person could only lead the team once.

As a result, everyone began to rush for this kind of research topic with only a piece of paper and a general idea and direction. After all, it is good to have a direction. How many researchers in later generations have died trying to determine the direction.

And those thick topics with implementation plans gradually spread according to the selection of external departments, external colleges, and external schools.

Anyway, you need to sign an agreement and agree to be included in unified management and enter the technology pool in the future. Whoever signs the name is not that important.

Therefore, the neighboring Imperial University and the Chinese Academy of Sciences can be said to be close to each other. Many such topics have begun to enter their research sequence, and they also adhere to the same principle, that is, each professor can only lead one such topic at most.

This kind of mysterious, almost manual-like research project is almost like smashing the scientific research results in the face. No one will be stupid enough to expose it, and they will only eat it secretly.

Then, after completing it, you can then look at the problem without a plan.

Of course, these operations are all under the eyes of the superiors, and these universities have also taken advantage of the trend to strengthen various reviews and inspections. Particularly important or sensitive topics require a higher-level hand.

Some were even confiscated directly, and then the finished products were mysteriously handed over to Mizuki on an unknown day, such as the kind of paint that can absorb electromagnetic waves, and an electromagnetic wave generating and receiving device called a TR unit.

Even the research on micromachines is mostly out of Shuimu's hands. It is estimated that it is quite difficult for them in a certain digital research institute. A lot of them have been closed down in recent years. Maybe the projects that Wang Xu has worked on can make these few Close one or two.

Under the guidance of Wang Xu, Shuimuna gradually began to conduct basic research. In fact, this is Mizuki's positioning. They are not good at concrete engineering and material research.

It's like there is a picture in later generations, which talks about the chief engineers of many great countries and important weapons. There is only one Mizuki, but there are many Seven Sons of National Defense. This incident caused an uproar on the Internet, and it could even be said to be the beginning of scolding Emperor Mizuki. After all, Emperor Mizuki didn't even have one.

But this matter seems very normal to Mizuki and Dida themselves, because those engineering projects are not their strengths in the first place, such as warships and aircraft. Even the aviation departments of these two universities have been separated to establish aviation academies. How could the chief engineer have their people?

Others are similar. Mizuki is still an engineering major, so there is still a scene for support, and Imperial University is a science major, so it is even more impossible.

A friend of Wang Xu's previous life told a story. Someone participated in the development of a certain fat aircraft and undertook a theoretical study on the design of brake discs in a heavy load, high temperature, and strong sand and dust environment.

This thing is completely a neck-stuck technology. It can be said that without his research, the short take-off and landing would be a joke. But if you look at the implementation list of the entire project, it is impossible to find him, because what he published is just a paper and has nothing to do with the project.

After all, his main job is to do various theoretical calculations, summarize empirical formulas, at most make a laboratory sample, and do some environmental experiments to verify the correctness of the theory.

When he accepted the project, he inspected it for a long time. Based on this, he could only guess that the thing was used on some kind of landing gear, but he didn't even know what model it was or how many wheels the landing gear had.

Later, someone made a finished product based on his thesis, but it really had nothing to do with him. He didn't even know where or how his thesis was used.

It wasn't until the plane appeared on XiaTV that he received a thank-you phone call, saying that his research was important.

This can be a story, but it is not entirely a story. The country has its own positioning for universities. Mizuki, Imperial University and some institutions of the Chinese Academy of Sciences are mostly engaged in basic research. The country needs them to go deeper, not Make it practical.

Just like the photolithography factory run by Mizuki in later generations, a paper from a few years ago was inexplicably turned out for hype, but it felt like it would be online soon.

But when the paper was published, Professor Mizuki said that this thing was just a theory of providing an extreme ultraviolet light source. Later, we conducted a verification experiment with a university in Hansi and found that it was feasible.

This is the end of Professor Mizuki's work. This achievement is enough for him to get a promotion and a salary increase. As for whether to continue, how to continue, and who will continue, it will naturally be arranged by the state. But theory is still theory, and it is still far from practicality.

In this life, with Wang Xu's influence, this trend may only go deeper, and there may be some practical research, but it will all be used to make money. And his use of Mizuki is not just to help Mizuki make money, he is the second best in the world.

Just like the research on electric vehicles, if it is a car manufacturer, it should start with a single motor and traditional chassis.

If it is an Internet company, it may start from the direction of vehicle-machine interconnection and autonomous driving.

The topics arranged by Wang Xu are electromagnetic suspension, wheel motors, superconducting shock absorbers, energy recovery, multi-axis attitude control, independent operation of single wheels, road surface perception, integral wheels, multi-sensor fusion, big data analysis, and intelligent learning. , and other sub-topics.

It is required to achieve body integration, functional modularization, communication bus, charging and discharging modularization, interface standardization, intelligent vehicle and machine, and unmanned driving.

When Wang Xu and Director Jiang introduced these projects, they said that these things may be just science fiction dreams, or even pure dreams, and there is no possibility of them being realized.

But Wang Xu added: "If it is an ordinary university, then it doesn't matter if you catch up or imitate.

But we are Shuimu. If we cannot lead our countrymen to dream, who else can. "
