Chapter 166 The Gift From the Vigorous Master

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, 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 superiors."

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.

In the original world before 2017, 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-mirrors 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!

So, the solution used is particularly mature, because MEMS projection display has been commercially available for many years.

However, as a semiconductor, the core technology of MEMS 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 in Europe, Mirrorcle in the United States, Hamamatsu in Japan, STMicroelectronics in Switzerland, MicroVision in the United States, etc.

However, MEMS micro-vibration mirror technology has also developed rapidly in recent years, and the cost of laser radar will be further reduced in the near future.

Of course, it is not that we do not make mechanical laser radar at all. We have also made great progress in research and development in this regard.

Companies such as Hesai Technology, RoboSense, and Leishen Technology, which were established relatively early, probably between 2013 and 2015, all have both mechanical and MEMS laser radars, and have good technical reserves for other solutions. They have already led the market.

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

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

Cao Shen naturally "accepted" this batch of "equipment" with a smile. If it weren't for the support of the old man, it would be really difficult for him to make this batch of things.

Originally, he wanted to treat him to a meal to express his gratitude, but he immediately withdrew his team.

As the saying goes, when the work is done, he will leave, hiding his merits and fame.

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

"Do you really want to make a car?"

Cao Shen nodded and smiled: "It's in the plan, it's in the plan!"

"High-precision maps" must be made.

As for the car, wait a minute.

I really don't have that ability yet. Batteries, motors and electronic controls, Cao Shen's lively talk makes it sound simple.

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

Not to mention the central control chip, which is still not in sight.

Well, the key is that I don't have that much life.

If I don't have a life to exchange, it will cost a huge amount of time and money to develop, manufacture and test the car myself.

Didn't you see that Boss Jia hasn't returned to China yet!

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

So, wait and wait.

Many companies fail, not because of starvation, but because of gluttony.

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

Recently, I have read a lot of popular science books, alas.

Please write a good review for me, I am so miserable...

Less than 100 people have read this book this month, which is worse than last month, so miserable.
