Chapter 181 What Traps Do You Have? Strong Popular Science, if You Don't Like It, You Can Skip It

According to Cao Shen's original calculation, it shouldn't take long for the system to get into trouble. It was also because of this that I agreed to Xu Mingzhe's dinner in the evening.

As a result, I didn’t expect that the system would take a day to complete.

Cao Shen also felt strange that it was such a big deal that it took so long.

This thing couldn't have gone astray!

Strongly request the system to show the results in progress.

When he saw it, he said, oh, he happily stroked his beloved general’s head:

"It's okay, we're not in a hurry, you take your time."

Although the system chirps every time before starting work, the work is really good!

Not only are they writing the operating system, the twin digital platform and modifying the "intelligent warehousing system" in accordance with Cao Shen's requirements.

The types and locations of sensors that need to be added to the entire system are also carefully marked.

Even better, additions and modifications have been made to the instruction set of the MIPS architecture.

Oh, this will directly allow the performance of MIPS to be more than doubled in the future.

In this case, Cao Shen rubbed his hands.

Alas, human nature is greedy.

Although I am just a "corpse" now, my original intention is still there, goose ho ho ho ho!

"System, you have improved the performance of the CPU."

[Yes, otherwise there is really no way to deploy a useful operating system, it can’t be brought along]

"After the CPU performance is improved, to what extent can the existing equipment achieve the efficiency of the smart warehousing system you proposed?"

【5%? 8%? 】

"Alas!" Cao Shen sighed deeply:

"It's a pity. It's obviously a good product, but the reality is so cruel that it can only exert such little effect."

The nerves in his system tightened and he wailed:

[Host, don’t even think about returning it!

I have already done my best! 】

"Look at the system. I spent a year of my life buying a smart warehousing system.

I definitely hope to be able to utilize it 100%.

As a result, because your product is completely out of touch, it can only perform less than 10% of its effectiveness.

Just say, am I at a loss?

I did not choose to come to this world.

Your products are not designed by me either.

I actually spent a year of my life, so the blame is definitely not on me. "

The system raised its hand, pointed it slowly at itself, and said with trembling lips:

[So...the blame lies with me? 】

"Yes," Cao Shen nodded seriously.

The system almost cried:

[Host, I don’t want to either. I didn’t do this or develop it.

I'm just a seller...]

Cao Shen touched the system's bald head and said kindly:

"I understand, I understand, you can be considered a scapegoat.

Otherwise, there is another way to improve the overall performance a little bit more, and you can do your best?

Let me not lose too much.

Otherwise, after this painful lesson, how could I dare to exchange my life for things in the future?

If you can't use the things you exchanged for it, aren't you just wasting your money?

Then, it’s too bullying! "

【No no no! ] The system grabbed Cao Shen's clothes with both hands and said sincerely:

[Quick, let me do my best!

Our products are still very good. Host, you must continue to patronize us in the future. 】

I also want to change my height, change my breasts, and change my appetite!

Cao Shen pointed to a six-axis robot and said:

“Actually, in addition to the CPU, you can try to improve the mechanical performance.

For example, the three core components of this industrial robot are reducer, servo system and controller.

These three parts directly determine the performance, reliability and load capacity of the industrial robot, and play a vital role in the overall robot. "

Gulu, the system swallowed.

These three pieces are indeed the core components of industrial robots, and together they account for 70% of the cost of the entire machine.

There is indeed improved technology!

But, that has to be exchanged!

Seeing that the system was silent for a long time, Cao Shen shook his head helplessly:

“Oh, forget it if it doesn’t work.

If the business doesn't work out, it doesn't matter if we don't buy anything from now on and just make friends. "

These three major parts that Mr. Cao wants are not only monopolized by foreign brands in the original world, but are also the main bottleneck restricting the development of China's industrial robots.

In Dongguo in 2012, there was even less drama.

So, um, I quite want it.

Industrial robots in the original world originated in the United States and flourished in Japan.

Since the birth of the world's first robot in the late 1950s, industrially developed countries have established a complete industrial robot industry system and controlled core technologies and product applications.

Four major families of industrial robots have been formed: Japan's Fanuc, Yaskawa, Switzerland's ABB and Germany's KUKA.

Japan's industrial robot technology was introduced from the United States in 1967, but it quickly overtook it and its industry position has been stable for a long time.

The global market share remains at around 60%, and once exceeded 90%. It has the most complete industrial chain supporting facilities and core technology reserves.

In terms of servo motors and CNC systems, it has long been a leader in technology research and application markets.

And here, the robots from Neon Country also dominate.

This is due to the lack of labor in Neon Country and the strong demand for machines with high production capacity and high degree of automation.

To this end, the Neon Government has long been committed to promoting the development of robots.

Even from the beginning, early cartoons such as "Astro Boy" and "Doraemon" introduced the positive image of robots to the general public in childhood and promoted their interest in robot technology.

At the beginning, this kind of animation was a kind of "political correctness" in Japan.

This also led to Japan being the country with the highest acceptance of robots among all countries, and there is a "robot" culture.

The United States is different. Their robots often play the role of "villains", wanting to kill humans and destroy the earth, and are the lackeys of aliens.

Therefore, some "anti-robotism" emerges from time to time in the United States.

Of course, in essence, this is also directly related to personal interests.

Japan has a lifetime employment system. Generally speaking, employees will work in a company for their entire lives.

Therefore, there is no need to worry about being abandoned due to the application of robots.

This plays a relatively positive role in the promotion of robots in Japan, at least it can reduce a lot of related resistance.

And the robots in the United States can be said to be born at the wrong time.

Robots were invented in the 1950s, but in the 1960s, the US trade deficit widened and the economy weakened.

Due to the large-scale investment of US President Lyndon Johnson in the "Great Society" and the war expenditures in the South.

The US economy entered a recession of 11 months in the late 1960s.

After the 1970s, in order to win votes, Nixon tried to avoid the economy from entering a recession again, and was committed to reducing the unemployment rate, and chose to implement an expansionary monetary policy.

Although it was slightly effective in the short term, it also led to a sharp increase in inflation a few years later.

In addition, he also made an operation that has far-reaching influence to this day, breaking the peg between the US dollar and gold in 1971. Directly turning the US dollar into an unanchored currency, it has depreciated significantly.

This laid the hidden danger for the economic recession in 1973.

High inflation forced the government to reduce inflation by raising bank interest rates, which brought a devastating blow to interest rate-sensitive industries such as real estate and automobiles.

This is also one of the reasons for the depreciation of the US dollar and the surge in oil prices.

The US dollar is a global settlement currency, but it has no anchor, which leads to it being flooded with water when it encounters problems, and then the whole world helps it pay.

This is why the East is doing everything it can to open the way to global currency.

It is precisely because of the economic recession in the United States that the research on robots has been "cut off" by the government.

And Japanese companies also took the opportunity to expand in the United States.

At the same time, due to the economic recession, the unemployment rate in the United States rose sharply in the 1970s, reaching 8.8% in 1973.

The serious unemployment problem not only made the US government, but also made the American people worry that the promotion of automation and robots may lead to further aggravation of unemployment.

Not only did the government reduce its investment in robot application research, but the people also had mental resistance.

The situation in the original world of the United States is similar.

As the birthplace of industrial robots, although the entire industry has gone from prosperity to decline and then recovered in the thirty years since the development of robots.

But they have a solid foundation and have mainly focused on special robots since 2000.

For example, space robots, military automatic vehicles and systems, and collaborative robots.

The "Mars Rover" in the Mars Exploration Program is a representative work of special robots.

As for other industrial robots, the United States currently mainly purchases robots and supporting equipment worldwide to carry out integrated production line design, peripheral equipment research and development, and integrated debugging.

Europe is mainly Germany, which has achieved complete autonomy in core components such as sensors, controllers, and precision reducers.

For servers, you still have to ask Japan for help.

However, German robots are world leaders in human-computer interaction, machine vision, and machine interconnection.

Germany introduced industrial robots five or six years later than the United Kingdom and Sweden. In 1971, there were less than 50 units, and no factory for manufacturing robots was established until 1972.

The German government realized the role of industrial robots in promoting industrial upgrading and issued the "Improvement of Labor Conditions Plan" in the 1970s.

It stipulates that dangerous, toxic, and harmful positions must be replaced by robots.

Under the strong requirements of the law, the development of German robots began to flourish.

At the same time, robots can not only significantly reduce production costs, but also improve product manufacturing precision and quality, thus creating a strong German manufacturing brand.

South Korea's industrial robots started slightly later than the United States, Japan and Germany. By introducing Japanese FANUC technology, it began to develop industrial robots, and Hyundai Heavy Industries and Samsung emerged.

In 2010, South Korea's industrial robot sales surpassed Japan to become the world's number one, but later it was obviously surpassed by Japan. However, South Korea has always maintained the world's highest level of industrial robot use density.

It can be seen that the history of the rise of great powers is also a history of industrial upgrading.

As the key supporting equipment for advanced manufacturing, industrial robots are the cornerstone of industrial upgrading.

Major economies such as the United States, Japan, and the European Union have raised the development of the robot industry to a national strategy.

Although China's robots started very late, it was not until 1985 that it had its first underwater robot "Hairen No. 1", the first six-degree-of-freedom joint robot "Shanghai No. 1", and the first arc welding robot "Huayu-I".

However, at the national level, the development of robot technology and applications is highly valued.

In the 1990s, nine robot industrialization bases and seven scientific research bases were established in China.

During this period, as companies such as Yaskawa, Panasonic, Fanuc, Kuka, and ABB entered China in batches and opened a large number of joint ventures, the commercialization of China's industrial robot market entered a stage of accelerated expansion.

The development of the market will promote technological progress and cultivate a large number of outstanding talents.

In the 12th Five-Year Plan 2011-2015, China proposed "intelligent manufacturing" and advocated that Chinese manufacturing companies increase the use of robots and automation.

Therefore, starting from 2010, China's industrial robots entered a period of rapid growth.

As of 2013, China's purchase of industrial robots has exceeded 30,000 units, ranking first in the world.

Since then, China has become the world's largest industrial robot market, accounting for 38% of the global total by 2019.

At the same time, the density of robot use has also increased rapidly.

From 15 units/10,000 people in 2010 to 187 units/10,000 people in 2019.

Although the improvement is fast, there is still a gap compared with South Korea's 855 units, Japan's 364 units, the United States' 228 units, and Germany's 1,131 units in automobile manufacturing.

From another level, it can also be seen that these countries with high-density use of robots are all major automobile manufacturing countries.

Indeed, automobile manufacturing plays a vital role in promoting the development, use and penetration of industrial robots.

The purchase of industrial robots by the automobile industry accounts for more than 30% of the total sales, and has always topped the list.

The second place is electronic manufacturing, accounting for 25%.

The development of China's automobile industry and electronics industry is complementary to the application and development of industrial robots.

In addition, with the rapid growth of the market and the progress of research and development, China's industrial robot industry chain is becoming more mature.

In the low- and medium-end markets, such as chemical and metal application fields, the localization rate has reached nearly 70%.

However, in high-end fields, such as automobile manufacturing and 3C electronics, it is still highly dependent on imports.

In China's robot research and development, core components, especially reducers, servo systems and controllers, are still almost monopolized by Japanese companies.

Looking at the history of robot development in China, although it has been accelerating, it is true that the late start has led to the patent protection and monopoly of core technologies.

In the future, there is still room for further growth.

Especially in the three core areas, it is not only the key to technology, but also the bulk of the cost.

Reducer, accounting for about 36% of the total machine cost.

The performance of the reducer determines the accuracy and load of the industrial robot.

It is an intermediate device connecting the servo motor and the actuator.

It is responsible for the power of the servo motor to achieve the purpose of deceleration through the small gear on the input shaft to engage the large gear on the output shaft, and transmit greater torque.

Each "joint" of the industrial robot requires a different reducer.

Moreover, as a transmission and load-bearing component, the reducer will inevitably be worn during use, and its lifespan is generally about two years.

So, this thing is a consumable.

During the average lifespan of eight to ten years of industrial robots, parts maintenance can be charged, and parts replacement can also be charged.

This business is very good.

This product has high technical barriers. At present, China's harmonic reducer research and development speed is relatively fast. In low-end application scenarios, it can already catch up with foreign products.

However, harmonic reducers are mainly used in robot joints below 20 kg, and the motion accuracy will be significantly reduced as the use time increases.

RV reducers have greater load capacity, high fatigue strength, long life, and are generally twice the price of harmonic reducers.

RV reducers are still mainly monopolized by Japan.

Nabtesco and Harmonaco account for more than 75% of the global market share.

Servo systems account for 24% of the cost.

In recent years, China's servo system industry has developed rapidly, and it is also the most promising part of the three core components to start domestic full substitution.

The servo system is generally composed of servo motors, servo drives and encoders.

It is generally installed at the "joints" of the robot.

Generally speaking, the more "joints" a robot has, the better its flexibility and the better its displacement accuracy.

Naturally, the more servo motors are needed.

The future development direction of the manufacturing industry must be the path of "intelligence" + "flexibility".

That means that future industrial robots must also become "flexible", smaller and more flexible.

More servos!

The market is bigger!

In the original world, the domestic high-end servo motor market was mainly occupied by foreign manufacturers, and the three Japanese companies Panasonic, Yaskawa and Mitsubishi occupied more than 50% of the market share.

The German companies Siemens, Bosch and Schneider had a market share of about 30%.

The domestic enterprises accounted for about 10%.

It doesn't seem much, but it is not easy to grab the market from scratch.

The cost of the controller accounts for about 12% of the whole machine.

The gap between China and foreign companies in hardware is already very small, and it is still slightly behind in software.

The controller is the brain of the robot control system.

Its main task is to control the robot's motion position, posture and trajectory in the workspace through a combination of various hardware and software.

Although the cost of the controller is relatively low among the core components, it plays a key role in controlling the robot.

Domestic industrial robot controllers have gradually matured in terms of hardware such as control boards, and have developed representative dual and multi-CPU and hierarchical control systems.

Although some underlying chips still rely on imports, the hardware solution of the controller has basically reached international standards.

The main gaps are reflected in software aspects such as control algorithms and secondary development.

Therefore, due to the lack of software technical advantages, it is slightly inferior in terms of operational accuracy and stability.

Currently, it can only be used in the general-purpose robot market with low precision requirements, such as handling, palletizing and other fields.

The development of Dongguo robots is not as good as that of China in the original world. Up to now, the three core technologies are completely lacking.

After all, Dongguo was founded much later and has missed the best opportunity for robots to start.

By the time they want to develop, various patented technologies have been firmly monopolized.

Therefore, Dongguo’s robots are highly dependent on imports.

The machines Cao Shen bought were naturally all overseas brands.

Moreover, because the AGV robot is specially customized, it also costs a lot of extra money.

The current robot usage density in Dongguo is similar to that in the original world in 2010, which is around 15 units per 10,000 people.

If Cao Shen wants to do "intelligent manufacturing", it will definitely not work without robots to do the work. It will all rely on other people's core technologies, so he will definitely not do it himself.

So, only the system can do it.

The system struggled for a long time and finally gritted his teeth and nodded.

After all, it’s better to “do business” than “make friends”!

Cao Shen saw that the three major modules of the modified system had obviously greatly improved the existing technology.

That means that using new solutions can make machines faster, more accurate, more durable, and more flexible.

From the underlying hardware to the machine to the system, the prototype of the entire intelligent manufacturing has been unfolded in Cao Shen's mind.

pretty!

Xu Mingzhe felt a little unhappy when he received the news that Cao Shen was letting go.

But, what's more, I feel relieved.

He didn't know why, but when he saw Cao Shen, he felt a little stressed.

When I told Lao Xu the news, Lao Xu stared:

"Aren't you coming?"

As he spoke, he poked Xu Mingzhe's head hard:

"Why do you give up so easily! People say you can't catch up in the evening, but they don't say you can't catch up at night.

Why don't you ask when people will be free?

Sincerity, how can you show your sincerity if you give up after someone gives up?

You are such a big man, you still need me to teach you this.

Mingzhe, I tell you, it is normal to encounter obstacles and difficulties when doing things.

Anyone who can achieve success must be able to endure it and survive all the way!

If you are just trying so little, how can things settle down..."

Xu Mingzhe was a little impatient. It was a rare meeting between the two men, so the old man took the opportunity to chatter.

He slapped Lao Xu’s fingers away with his hand:

“Definitely!

no!

Today is the first day of East Joy. We were partying on the cruise ship in the evening.

Where can I find the space? "

Old Xu Yi frowned:

"Have a party, have a party, you party every day.

There is a party on the cruise ship and all the demons are dancing wildly, is it important for you to meet Cao Shen?

Why can’t I carry it clearly? "

"Okay, okay! I'll ask him to come on the cruise ship!"

So what are you doing? Are you coming tonight too?

Don’t take a nap when you’re old! "

"Hey!" Old Xu slapped Xu Mingzhe on the back of the head:

"No matter how old you are, I'm no worse than you at staying up all night!"

"Who dozes off on the sofa with the TV on at nine o'clock in the evening!" Xu Mingzhe retorted.

"Am I dozing off? I closed my eyes and listened!" Lao Xu was dissatisfied.

"Haha, as I get older, my mouth is still tough..." Xu Mingzhe muttered in a low voice.

"What did you say!" Lao Xu didn't hear clearly.

"I said, OK, OK, send him a friend letter immediately and invite him to come on the cruise!"

"Hey, that's right.

Besides, this Cao Shen is also a young man, well, a little younger than you.

It’s also nice to meet on the cruise ship, the atmosphere is relaxed.

Let me tell you, the atmosphere when talking about things is also very important. When everyone is relaxed, it is easy to get closer..."

"Haha, so you liked to talk things out in nightclubs in your early years?"

"Hey!" Lao Xu patted his thigh:

"That's because of work needs. Besides, back then, you and I had many discussions in nightclubs to get things done.

Without me, how would you be able to enjoy the fine clothes and food you have now?

Remember when I..."

"Okay, okay, don't think about the old days, I'm sending a friend letter." Xu Mingzhe immediately interrupted Lao Xu's "I was brave in the past" tirade.

Cao Shen received Xu Mingzhe's invitation and said to the system:

"Can we catch the late flight back?"

The system raised its head, and there was a little smoke on the bald head:

【You think too much】

"Okay, don't worry!" Cao Shen pressed the system's shoulder and said very friendly:

"After you finish your work, I'll take you to a big dinner in the evening!"

The system felt nervous:

[Host, what’s wrong with you! Make it clear! 】
