Becoming the richest man starts with making complaints

Cao Shen quickly changed his clothes and came to the company, haha.

You promised not to spy on me!

He ran up to someone and said:

"Leader, what's going on?"

"Hello, Mr. Cao!"

Cao Shen also quickly gestured:

"Comrade leader! What's the matter?" He wanted to say that I had committed something, but he quickly stopped.

Xiao just left, so it’s not like that...

The leader took out a document in a brown paper bag from his arms, took out a pen from his coat pocket and handed it to Cao Shen, solemnly saying:

"Excuse me, is this Mr. Cao Shen?"

"yes!"

"Mr. Cao, please show me your ID."

There is a feeling that I need to verify my identity...

Fortunately, Cao Shen brought his ID card and took it out and handed it to the leader.

The leader looked at the certificate carefully and then looked at Cao Shen's face. After a long while, he handed the certificate back to Cao Shen:

"Sorry, we must strictly follow the prescribed procedures."

Then he handed the "document" to Cao Shen:

"Please also ask Mr. Cao to sign for it. The superior department specially asked us to transport it this morning."

"Oh, okay." Cao Shen took the document and asked, "Excuse me, what are these?"

"This is the latest laser radar developed by our country. There are twenty units in total. Please sign for it."

With that said, he took out another letter from his pocket and handed it to Cao Shen with both hands:

"This is a letter from your superior."

letter?

Cao Shen has not seen such a "traditional" object for many years.

I turned it over carefully and saw that there was no "mechanical seal" or anything like that. It shouldn't be a confidential document.

Take it apart decisively!

"Xiao Cao:

The rotating lidar you need to make high-precision maps is not manufactured for civilian use in China.

If you want to import, you still need special approval.

And in terms of price, you can’t afford it according to your budget.

In order to support your work, I have specially approved 20 laser radars to be sent to you.

I hope it can help you achieve success as soon as possible!

Also, your advice is very pertinent.

In order to develop our country's autonomous driving technology, we will make some lidar technologies available for civilian use and commercialization as soon as possible.

Allow more vehicles to be equipped with this equipment at low cost.

Thank you for your contribution to the country, let us work together! "

It's the handsome uncle!

Cao Shen's hand holding the letter shook.

It was delivered this morning. It was dispatched and transported overnight.

It would be a lie to say that I am not impressed.

This is Dongguo’s determination and execution in doing things...

Your uncle is your uncle, so awesome!

It was Cao Shen's impromptu idea at the beginning, and no matter how strong he was, he would never be fully prepared.

Basically, it is to organize ideas and language according to the memory of the previous life.

But Cao Shen obviously didn't care. It's now 2012, and the price of laser radar is still very high. Moreover, there is indeed no military-to-civilian conversion in the country.

The cost of his professional surveying and mapping vehicle was roughly estimated based on what it would be in seven or eight years, and he didn't bother with it at the beginning.

It is indeed a good thing that the laser radar military is converted into civilians.

Before 2017 in the original world, the number of imported laser radars ranged from tens to hundreds of thousands, and there were even high-precision ones with millions of units.

But once something is started, the price can be cut in half again.

The civil use of lidar technology began in 2005. Of course, civilian use entered even later, which resulted in the early reliance on imports and high prices.

It was not until 2017 that civilian users began to enter the lidar market, forcing foreign manufacturers to cut prices.

In 2017, the official pricing of Velodyne's 64-line, 32-line, and 16-line mechanical lidar were US$80,000, US$40,000, and US$8,000 respectively.

By early 2018, Velodyne had cut the price of its 16-line lidar by half to US$4,000.

In January 2020, DJI released the Horizon, which was priced at US$800.

The cost of the 96-line lidar released at the end of 2020 has been directly reduced to less than 200 US dollars.

Of course, it is undeniable that we do have shortcomings in "core technology".

But there seems to be a talent, which is the "micro-innovation" that foreigners are most afraid of.

We are particularly good at putting together various core technologies to create something cheap and easy to use, and then bombing the market and leaving others confused.

In terms of extensive mastery and flexible application of various technologies, creativity is unparalleled.

Take laser radar as an example. The reason why it is so cheap is not to follow the path of mechanical radar according to foreigners' ideas.

Mechanical lidar requires multiple laser emitters to achieve a high wire beam. At the same time, the scanning system relies on motors, and the costs of components, manufacturing, and systems are extremely high.

Make efforts to make MEMS semi-solid radar.

MEMS micro-mirror is essentially a silicon-based semiconductor component, which is characterized by the internal integration of "movable" micro-mirrors, which are driven by electrostatic or electromagnetic means.

The use of MEMS micro-galvanometers simply means replacing the motor-based scanning system with MEMS-driven lenses to achieve lidar scanning.

The introduction of MEMS can reduce the number of lasers and detectors and greatly reduce costs. Moreover, this kind of laser radar has a sophisticated structure, which greatly reduces the size of the radar and is more suitable for commercial use.

The MEMS micro-mirror was not used for radar before, but for projection display!

Therefore, the solution used is very mature, because MEMS projection displays have been commercially available for many years.

However, as a semiconductor, MEMS' core technology is mainly in the hands of overseas companies. Currently, the top 30 MEMS companies in the world are all well-known overseas semiconductor companies.

For example, Innoluce from Europe, Mirrorcle from the United States, Hamamatsu from Japan, STMicroelectronics from Switzerland, MicroVision from the United States, etc.

However, MEMS micro-mirror technology has also developed rapidly in recent years, and further reductions in lidar costs are just around the corner.

Of course, this does not mean that we will not make mechanical lidar at all. Our research and development in this area has also made great progress.

Companies such as Hesai Technology, Sagitar Juchuang, and Leishen Technology were established relatively early, probably between 2013 and 2015. They all have both mechanical and MEMS laser radars, and they have good other solutions. Technical reserves, they have led the market.

Latecomers DJI and Huawei are also very strong in the research and development of laser radar.

It can be said that the current commercial lidar technology is the first echelon in the world, and even has a leading position.

Cao Shen naturally "accepted" this batch of "equipment", but without the support of the handsome man, it would have been very difficult for him to get this batch of things.

I originally wanted to treat him to a meal as a token of my gratitude, but he immediately stopped my team.

It is said that when the matter is over, you just brush off your clothes and hide your merit and fame.

The senior sister looked at the "goods" filling the square and said to Cao Shen:

"Do you really want to drive?"

Cao Shen nodded and smiled: "It's planned, it's planned!"

"High-precision mapping" is definitely something to do.

As for the car, let’s wait.

He really doesn't have the strength yet. Batteries, motors and electronic controls, Cao Shen said in a lively way, sounds like they are very simple.

But it's complicated to assemble these things together and run them as a car.

Not to mention the central control chip, which is still missing.

Well, the point is, I don’t have that many lives yet.

If you lose your life and develop the car yourself, it will cost a huge amount of time and money.

Didn’t you see that Boss Jia hasn’t returned to China yet?

Moreover, I am still short of money, time and life for my own education.

So, wait, wait.

Many companies fail not because they starve to death, but because they starve to death.

Cao Shen is a very smart person, but he doesn't want to die. He has many more pressing things to do...

Recently, I have been losing a lot of popular science reading, alas.

Please help me write a good review, I'm so miserable...

Less than a hundred people have read this book this month. It’s not as good as last month. Wow, wow, how miserable.
