Chapter 536 Professor Lu Leads the World Again

Robotics is a systems engineering.

Including materials technology, computer technology, machining technology, electrical control technology and many other technologies.

At present, the bottleneck restricting the development of robotics technology in my country is mainly three major parts: reducer, servo motor, and control system.

Well, remove these three big pieces, and there's nothing left.

For the next period of time, Lu Li focused on the research and development of the speed reducer technology.

Reducers are the key to robotics.For a robot to perform a certain action, it must precisely control the action to ensure that there is no slightest error.

Here, the reducer is the key.

If the reducer is not qualified, no matter how accurate the data set by the control system is, the corresponding action requirements cannot be realized.

From a certain point of view, the reducer of a robot is actually very similar to the gearbox of a car, and they all work on the same principle.

But... the technical requirements are completely different from heaven to earth.

The research and development of domestic robot reducers is very difficult, because the reducer itself requires extremely high precision, and the machining accuracy of parts has reached the micron level.

This precision is unimaginable, and it is only one unit higher than the nanometer level of silicon-based chip lithography technology.

To achieve such processing accuracy, it involves processing equipment, operator technology, process flow arrangement, environmental conditions and so on.

For example, when performing this kind of precision machining, if you cough, it may affect the machining accuracy.

In addition, the design of the reducer is also the key.In this regard, the lack of advanced design in this area in China has resulted in the performance of the reducer failing to reach the foreign level.

For Lu Li, design was not a problem at all.

The robot technology in Sanctuary Technology, of course, includes the design schemes of various high-precision reducers, as long as they are copied.

But... the design alone is not enough, the problem of machining accuracy must also be solved.

The reducer of the refuge is manufactured and precision processed using laser processing technology.This technology... can be used.

Before the controllable nuclear fusion is developed, the use of laser processing technology will result in huge energy consumption and high production costs, but... this is the problem of whether there is a solution.

On some key equipment, whether it is available is the most important, and the energy consumption and cost are completely negligible.

The first step is to come up with high-precision laser processing technology!

This technology belongs to the nature of tools and can be widely used in the processing of various high-precision parts, not just for processing reducers.

Such as aerospace, such as aviation, such as missiles, such as nuclear submarines, such as aircraft carriers...

An inertial gyroscope, like using high-precision laser processing technology, can improve the accuracy of the gyroscope by an order of magnitude.This can greatly improve the guidance accuracy in aerospace and missile technology.

The high-precision laser processing technology of the shelter can be directly taken out.

Lu Li sat at his desk and began to compile material lists, equipment lists, technical theory documents, and plan experimental procedures.

"Old Tian, ​​I want these equipment and materials!"

Lu Li called Assistant Tian over and handed him a list.

This list includes the processing equipment and materials needed by Lu Li.Lu Li planned to make a prototype of a high-precision laser processing equipment in the laboratory.

Assistant Tian hurried into the office and took the list from Lu Li.

"Professor Lu, I will report to the higher authorities immediately. What you want will be delivered in the shortest possible time."

Seeing this long list, Assistant Tian became excited again.Obviously, Professor Lu is about to come up with a sophisticated new technology.

Why am I not surprised at all?

Assistant Tian smiled, ran out of the office in a hurry, reported the situation to the higher-ups, and submitted Lu Li's list.

"Professor Lu is going to do research again?"

The chief above received the list, and seeing the strings of equipment and materials on the list, a smile appeared on his face.

equipment?Material?It's not a problem!

Professor Lu will give whatever he wants, and no matter how much money it costs, he must prepare it in the shortest possible time.

Today's Lu Li is already a national treasure-level scientist.

Which of the technologies that Lu Li has brought out before is not world-leading?How important is the strategic value of successful research on these technologies?How many technological breakthroughs and technological progress have been brought to the country?

A day later, a heavy rotor transport aircraft slowly landed at Baoshan Base.Various equipment and materials needed by Lu Li were continuously sent to the underground laboratory.

This heavy-duty rotorcraft is the Iron Bird rotorcraft developed by Lu Li before.

After a period of technical verification, the iron bird rotorcraft has begun mass production and large-scale equipment has begun.

Lu Li didn't care about this at all.

After the equipment was installed and the materials were sent to the laboratory, Lu Li started working.

For the next week, Lu Li continued to work in the laboratory.With 3D printers, high-precision CNC machining centers and other high-precision equipment, Lu Li slowly assembled the parts of a high-precision laser processing equipment.

The overall structure is made of titanium-chromium-tantalum-carbide hard alloy developed by Lu Li himself.The laser emission port is made of tantalum carbide high temperature resistant material.

The control chip uses a gene chip, the wire uses graphene, and the transmission mechanism uses a carbon nanotube composite material.

Various parts are assembled one by one, and a high-precision laser processing equipment is officially completed.

This is a prototype machine, naturally not that particular, it doesn't even have a casing, it looks a bit rough, but... the technical content is extremely high.

After turning on the power and starting the equipment, Lu Li entered the blueprint of the reducer he had designed into the gene chip computer of the laser processing center, installed the material on the fixture, and reached out his hand to press the start button.

Then... the machine runs automatically, the laser hits the material, and the cutting process starts.

The advantage of laser cutting is that it does not need to change tools at all, from rough machining to finishing machining, it can be cut across the board.

After half an hour, the core part of the reducer, the precision component of the pendulum planetary wheel, has been processed.

After removing the parts, Lu Li used high-precision measuring equipment to test the accuracy of the parts.

The test results show that the accuracy of the parts fully meets the requirements, and the surface roughness, dimensional tolerances, fit tolerances, coaxiality...etc. errors, the maximum error is not more than 1 micron.

This is already the top precision in machining technology.

The high-precision laser processing equipment fully meets the design requirements and has been successfully researched.

The only downside is... this thing consumes more power.

Before the advent of controlled nuclear fusion, the use of laser processing technology would lead to relatively high production costs.

However... For a country, this top-level high-precision processing technology only needs to solve the problem of whether it is available, and it doesn't care about the cost at all.

Who cares about the cost of this strategic high-precision machining technology?

Without this technology, the cost to achieve ultra-high-precision processing would be more than a hundred times higher.

After successful research, or "successful plagiarism", Lu Li turned around and returned to the office to start writing technical materials.

Lu Li wrote down the theoretical information, design scheme, production process, all experimental processes and experimental data of the high-precision laser processing technology in detail.

After doing this, Lu Li started to summon Assistant Tian again.

"Old Tian, ​​come and receive the goods!"

Lu Li turned his head and shouted, Assistant Tian quickly appeared.

"Professor Lu, your research...is successful again?"

Assistant Tian smiled, well, why should I say "again"?

"I developed a high-precision laser processing technology."

Lu Li took out the technical information and handed it to Assistant Tian, ​​"There is also a design drawing and processing technology of the reducer. You can hand it in!"

"Yes!"

Assistant Tian quickly took the order.

Although I can't figure out how important this technology is, there is nothing that Professor Lu has researched that is not high-tech.

Soon, this technical information was submitted to the head of the military.

"High-precision laser processing technology? And reducer design?"

The military chief didn't specialize in technology, so he couldn't figure out how valuable Lu Li's research material was.

It doesn't matter if the chief doesn't understand, as long as the people below understand it.

The head of the military immediately forwarded this technical information to the General Armament Department, allowing technical experts to conduct technical demonstrations.

"A high-precision machining technology with an error of less than one micron?"

The technical experts of the General Armament Department all stared wide-eyed after seeing this document.

This is the top high-precision machining technology.This is a high-tech with great strategic significance.

In the defense industry, as well as the aerospace industry, the pursuit of precision is almost endless.

High precision means high performance and high reliability.

This technology is of great strategic significance in the processing of parts for space stations, satellites, launch vehicles, and even strategic weapons.

To put it simply, how much positioning and navigation accuracy can an ultra-high-precision gyroscope bring?

The accuracy of the landing point of Dongfeng Express can also be improved by an order of magnitude, and the error can reach no more than ten meters.For a strategic weapon, this accuracy is simply appalling and completely excessive.

"Professor Lu is too strong!"

An expert couldn't help sighing, "Professor Lu also has such high attainments in precision machining technology. Is there anything else he doesn't know?"

"Huh? Look! Behind this document, there is also a design drawing and processing technology of the reducer."

An expert next to him saw the technical data of the reducer listed at the end of the document, and his face was dull. "Everyone, I have a guess. Could it be that Professor Lu has developed high-precision machining technology for the purpose of processing the reducer?"

"I'm afraid it is."

Another expert looked helpless, "For example, because you want to eat eggs, you get a hen that lays golden eggs. The world of geniuses is really unimaginable."

"Compared with this ultra-high-precision processing technology, the reducer is nothing! This is just a small application direction of high-precision processing technology."

"I'm afraid even Professor Lu himself doesn't know how important this high-precision machining technology is strategically important."

"If Professor Lu thinks that charging a mobile phone is too troublesome, will he come up with controllable nuclear fusion technology?"

"Haha! Maybe it's really possible!"

This ultra-high-precision laser processing technology was quickly verified by technology.

The Ministry of Aerospace Industry immediately took this technology over, and produced a batch of high-precision laser processing equipment according to the technical data, which fully proved the reliability of this technology.

All of a sudden, various high-tech departments rejoiced.

Those who produce satellites need this technology, those who produce launch vehicles need this technology, those who produce aircraft need this technology, those who produce missiles need this technology, those who produce nuclear submarines need this technology, and those who produce aircraft carriers need this technology...

Various processing equipment based on high-precision laser processing technology have sprung up like mushrooms after rain.

Of course, Lu Li's reducer design scheme has also been widely used.

Aren't the current high-precision processing equipment all automated equipment?A high-performance reducer is also very important.

It's just... Compared with the high-precision laser processing technology itself, the technology of the reducer is just a component technology.

Domestic high-precision processing equipment has begun to be fully updated.

Because the country already has this high-precision processing technology, the negotiations with the Teutonic country to introduce technology have completely stopped.

Originally, the Teutonic Kingdom had put on a high-ranking attitude, ready to swing a knife to kill fiercely, but the lion opened its mouth wide and called out the astronomical price.

More importantly, the technology given by the Teutonic Kingdom is still backward, and the processing accuracy can only reach [-] microns.

Now... sorry, we don't want it anymore!

Knowing that Huaguo no longer needed [-]-micron precision machining technology, the Teutonic nation was dumbfounded.what's going on?Why did the rabbit suddenly not want this technology?

Although we have eliminated the [-]-micron precision machining technology, but... don't you have it?

You are sharpening your knife, why don't you come to be knifed?

At the same time, on the international black market, buyers looking for high-precision processing technology everywhere disappeared in a short time.

Many people who were about to use the elimination technique to ruthlessly slaughter the rabbit were all inexplicably horrified and completely confused about the situation.

"News from our station: Professor Lu Li, a famous scientist in my country, has developed a new generation of high-precision machining technology. The machining accuracy has reached the micron level, and the error does not exceed one micron."
