There are many types of robots according to their use.

For example, there are industrial robots, agricultural robots, household robots, medical robots, service robots, underwater robots, military robots, disaster relief robots, education and teaching robots, entertainment robots and so on.

According to the importance of robot components, it is divided into three categories, and each type of sensor accounts for 20%, such as ultrasonic sensors, temperature sensors, humidity sensors, gas sensors, gas alarms, pressure sensors, acceleration sensors, etc.

Then the actuator accounts for 30%.

Actuators are divided into two categories: "Motion Module" and "Behavior Module".

The motion module is divided into: tracks, wheels, slide rails, robotic arms, etc.

The behavior module is divided into: solenoid valve, reducer, servo motor, etc.

The remaining 50% is the core control system.

This thing is equivalent to the human brain, no matter how sensitive your eyes, ears, throat and nose are, and how developed your body and limbs are, there is no intelligent brain to direct and use them, and it is as big as a white man.

For example, there are two main criteria for measuring the advantages and disadvantages of industrial robots: stability and accuracy.

The core control system is a key component that affects stability, which is called the "brain" of industrial robots, and software is equivalent to language, which transmits the ideas of the "brain".

To speak this "language" well, the underlying core algorithm is required.

The "four families" of Japan Benfanuc, Yaskawa Electric, Sweden's ABB, and Germany's Kuka (acquired by Midea Group in 2018) can sell key components such as sensors, servo systems, reducers, and encoders to China, but the core algorithm has been kept secret and never leaked.

If you don't master the core algorithm, it is barely possible to produce products that do not require high precision, but in high-end fields such as aerospace and military industry, you can only rely on imported industrial robots.

Algorithm garbage will not only slow down the response speed of the servo system, but also the collaborative operation of multiple servo systems is unbearable to look at.

The foreign core control system can directly operate the motor through the current loop of the servo system to achieve precise control under the condition of high dynamic multi-axis nonlinearity, which is a mess.

It is precisely because of the gap in algorithm software that the price of the product is also very different.

Taking the servo system as an example, even if the core components are exactly the same, the price of foreign products is more than 10 times more expensive than that of domestic products.

In view of this, Chen Xu has developed hundreds of core control systems and servo systems for dozens of robots such as industrial robots, household robots, service robots, underwater robots, teaching robots, and entertainment robots.

After comparison, the stability and accuracy of these core systems are far better than those of the four major families.

At this time, a month and a half has passed since Chen Xu buried himself in the laboratory.

The time has also entered April.

When he washed his hands and looked in the mirror after work at night, he found that although his beard had been shaved by Tong Lisha, his long flowing hair had completely covered his ears.

He vaguely remembered that he seemed to have not had a haircut for nearly half a year.

Out of the bathroom, there is a long corridor outside, and on the west-facing side is a row of glass windows, and the fire clouds on the horizon are reflected on the window glass, smearing the red glow, which is beautiful.

Chen Xu was addicted to cigarettes, walked to one of the glass windows, stopped, and lit a cigarette.

There is an ashtray on the windowsill.

Just as he was about to recite two lines of poetry, such as "The sunset is infinitely good, but it is just near dusk", an office door behind him opened, and Jiang Yuqi, the head of the laboratory team, walked out.

Seeing Chen Xu standing at the window, Jiang Yuqi greeted, "Chen Suo hasn't gotten off work yet?"

Chen Xu smiled: "I'll leave after smoking this cigarette." ”

Jiang Yuqi came over and said with a smile: "I watched the news last night, and the wireless charger project has been officially approved. ”

"Well, the project was originally planned to be established at the end of this year, but it wasn't because you just invented the cubic silicon carbide antenna, so it was ahead of schedule. ”

Jiang Yuqi smiled and said: "What Chen said is serious, I am completely standing on a huge shoulder... No, it should be standing on your shoulder. ”

"Hehe, humble~" Chen Xu smiled and followed: "The company has established a long-distance wireless charging alliance, and the standard name is it... You are one of the inventors, there are five people in total, let's call it the J5 standard. ”

Jiang Yuqi let out an "ah", and then shook his head again and again, "How can this work... Chen, don't be kidding, I..."

Chen Xu Yuguang saw the Audi Q8 that Tong Lisha had just bought appear at the gate of the laboratory, extinguished the cigarette in his hand, and said with a smile: "It's so decided, let's go first." ”

Watching Chen Xu hurriedly run down the stairs, Jiang Yuqi couldn't cry or laugh.

The standard naming right, this is a great honor for scientific researchers, this director is actually like a child, just let it be given to her, isn't it a joke.

Jiang Yuqi stood by the window and thought about it, and finally shook his head.

Although it is very tempting, this kind of honor of deceiving the world and stealing fame is not only disgraceful, but also despised.

Because there were four other people involved in the experiment, everyone knew who the real inventor was.

……

Xinghai Technology's long-distance wireless charger has been officially established.

Although the technical description in the project plan and the shareholders are unknown to the outside world, one thing is certain - there is no technical problem with the long-distance wireless charger!

Originally, countless doubts from the outside world were dizzy by this sudden "slap", and they were deaf and tinnitus.

It's too fast, from Xinghai Technology's announcement that the wireless charger will be listed within the year, to the project approval, a total of only a month and a half has passed.

It's amazing.

There is another thing that has also made countless investors talk about it.

At two o'clock in the afternoon on Valentine's Day on February 14, Xinghai Technology announced the issuance of financing bonds of 5 billion yuan, with a maximum maturity of more than 20 years.

However, in less than 24 hours, on the morning of February 15, Xinghai Technology issued an announcement saying that the required funds had been raised.

A technology company that has only been established for a year, such a big appeal has shocked countless people who don't know the details of Xinghai Technology!

On the other side, the Sword and Shield mobile phone security guard, according to the active user data released on January 31, has become China's well-deserved No. 1 mobile phone security guard with more than 10% of the data of Tengxun Security Guard and 15% of 36 Zero Security Guard.

This data is still expanding with the super good use of Sword and Shield Mobile Security Guard.

And unless Tengxun and 36 Zero also develop a super firewall and anti-tracking system, the gap will only grow with time.

Teng Xun didn't have much reaction to this.

After all, the family is a big business, and the mobile phone security guard is just a channel for them, it is better to make money, and it doesn't matter if they can't make money, it is impossible to spend too much energy to fight the sword and shield, and they can't knock it, and they will let it go after a symbolic resistance.

Anyway, Tengxun's plate is here, and it is impossible for other mobile phone security guards to die completely!

But 36 Zero really can't do it.

Although the mobile phone security business has shrunk to a certain extent, compared with the 360PSP business, search business, game business, and enterprise security business, it is not even a fraction.

But don't forget what 36 Zero started on.

The mobile phone security guard is the biggest signboard of 36 zero mobile business, just like the importance of Weixin QQ to Tengxun, the image project must not be lost.

Throughout February and March, 36 Zero invested heavily in an overwhelming campaign on the Internet.

Just like brain platinum, you don't need a mobile phone security guard for the holidays this year, and you can use 36 zero if you want to use it.

As for the effect, I don't know, anyway, since April 1, all the overwhelming propaganda on the Internet has disappeared.

As of March 31, the market value of 360 is less than 50 billion.

Compared with the market value of 450 billion at the peak of 18 years, there is only a fraction left.

On the other hand, relying on strong technical advantages and [China Cyber Security Alliance], the shipment of security products of Xingjian Technology continues to increase.

In the first quarter of 2020, revenue reached a staggering 27 billion yuan, and the net profit was not enough.

In addition to laying product lines in Beijing, Shanghai, Guangzhou and Shenzhen, as well as a number of strong first-tier cities, Xingjian Technology has also built branches in six countries, including Japan, Hanguo, Singapore, Germany, and the United Kingdom.

Foreign security companies have exclaimed "the wolf is coming".

……

Monday, April 6 at 10 a.m.

In the lounge area of the hall on the first floor of Changfeng Building in Binhe District, three or four girls dressed in very fashionable and beautiful clothes were leaning their heads together and laughing quietly.

At this moment, one of the girls glanced at the entrance of the hall and said with a hint of surprise: "Hey, Xiaoying, your dark horse prince is here." ”

The girl with long black straight hair who was looking at her phone on the right hand side of the girl immediately raised her head when she heard the words, revealing a fair and beautiful face, with the unique temperament between her eyebrows, she is also a big beauty with 8 points +.

"Hey, who's that woman next to him?"

"Hey, I think I've seen her somewhere. ”

"I think I've seen her... What's your name......

"Don't think about it, she is Shen Yiqiu from the law school. The black straight girl said, put away her mobile phone, stood up and smiled: "Let's go, say hello and ......"
