My Life Simulator

Robotics is a systems engineering.

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

At present, the bottleneck restricting the development of my country's robot technology is mainly the reducer, servo motor, and control system.

Well, remove these three pieces, and there is nothing left.

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

Reducers are the key to robotics. For a robot to perform an 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 turned off, no matter how accurate the data set by the control system is, the corresponding action requirements cannot be achieved.

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

But... the technical requirements are completely different.

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

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

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

For example, when performing such 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 domestic lack of advanced design in this area, resulting in the performance of the reducer can not reach the foreign level.

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

The robot technology in Refuge Technology, of course, includes various high-precision reducer design schemes, as long as it is copied.

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

The reducer of the shelter is manufactured using laser processing technology for precision machining. This technology... can be used.

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

In some key equipment, whether there is or not 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 the tool and can be widely used in the processing of various high-precision parts, not only for the processing of reducers.

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

An inertial gyroscope, like the use of 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.

Sitting at the desk, Lu Li began to write the material list, equipment list, technical theoretical documents, and plan the experimental steps.

"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 required by Luli. Lu Li prepared to make a prototype of a high-precision laser processing equipment in the laboratory.

Assistant Tian walked into the office in a hurry and took the list from Lu Li.

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

Seeing this long list, Assistant Tian was excited again. Obviously, Professor Lu is about to come up with another high-tech new technology.

Why am I not surprised at all?

Assistant Tian smiled and ran out of the office in a hurry to report the situation and submit Lu Li's list.

"Professor Lu is going to do research again?"

The chief above received the list and saw a string of equipment and materials on the list, with a smile on his face.

equipment? Material? It's not a problem!

Professor Lu will give what he wants, no matter how much he spends, 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 leading the world? How important is the strategic value of the successful research of these technologies? How many technological breakthroughs and technological progress have been brought to the country?

A day later, a heavy-duty rotorcraft slowly landed at the Baoshan base. The various equipment and materials that Lu Li needed were continuously sent to the underground laboratory.

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

After a period of technical verification, the Iron Bird rotorcraft has begun mass production and has begun to be equipped on a large scale.

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 was working in the laboratory. With the help of high-precision equipment such as 3D printers and high-precision CNC machining centers, Lu Li slowly assembled the parts of a high-precision laser processing equipment.

The overall structure material is the 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 is made of gene chip, the wire is made of graphene, and the transmission mechanism is made of carbon nanotube composite material.

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

This is a prototype machine, naturally not that particular about it, not even a casing, it looks a bit rough, but...it's very technical.

After turning on the power and starting the equipment, Lu Li put the speed reducer drawing he designed into the gene chip computer of the laser processing center, installed the material on the fixture, and reached out and pressed the start button.

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

The advantage of laser cutting is that it does not need to change the tool at all, and it can cut to the end from roughing to finishing.

After half an hour, the core components of the reducer, the precision components of the pendulum planetary gear, have been processed.

Remove the parts, and use 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 tolerance, fit tolerance, coaxiality, etc. errors, and the maximum error is not more than 1 micron.

This is already the highest precision in machining technology.

High-precision laser processing equipment, which fully meets the design requirements, 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... This kind of top-level high-precision machining technology, for a country, only needs to solve the problems that exist, and does not care about the cost at all.

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

Without this technology, to achieve ultra-high-precision machining, the cost is more than a hundred times higher.

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

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

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

"Old Tian, ​​come here to receive the goods!"

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

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

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

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

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

"Yes!"

Assistant Tian quickly took the order.

Although it is unclear 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 military chief.

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

The military chief wasn't specialized in technology, and for a while he couldn't figure out how valuable Lu Li's research materials were.

It doesn't matter if the chief does not understand, the people below will do.

The military chief immediately forwarded the technical information to the General Armament Department for technical experts to conduct technical demonstrations.

"High-precision machining technology with an error of no more than one micron?"

The technical experts of the General Armament Department widened their eyes one by one after seeing this information.

This is the top-level high-precision machining technology. This is a high-tech of 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 has great strategic significance in the processing of parts for space stations, satellite parts, launch vehicles, and even strategic weapons.

The simplest point, how much positioning and navigation accuracy can an ultra-high-precision gyroscope bring?

The drop point accuracy 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, a total excess.

"Professor Lu is too strong!"

An expert couldn't help but sigh, "Professor Lu also has such high attainments in precision machining technology. Is there anything else he can't do?"

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

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

"I'm afraid it is."

Another expert looked helpless, "For example, because I wanted to eat eggs, I created a hen that lays golden eggs. The world of genius is really unimaginable."

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

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

"If Professor Lu thinks it's too troublesome to charge the phone, will he bring out the controllable nuclear fusion technology?"

"Haha! Maybe this is really possible!"

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

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

For a while, various high-tech departments rejoiced.

This technology is required for the production of satellites, the technology for the production of launch vehicles, the technology for the production of aircraft, the technology for the production of missiles, the technology for the production of nuclear submarines, the technology for the production of aircraft carriers...

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

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

Isn'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 only a component technology.

Domestic high-precision processing equipment began to be fully updated.

Because this high-precision machining technology is already available in China, the negotiations with the Teutonic countries to introduce technology have completely stopped.

Originally, the Teutonic Kingdom also put on a lofty posture, ready to slap the knife and kill it fiercely, the lion opened its mouth like a lion, and shouted the astronomical price.

More importantly, the technology given by the Teutonic Kingdom is still backward technology, and the processing accuracy can only reach 30 microns.

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

The Teutonic state was stunned to learn that the Chinese state no longer wanted the 30-micron precision machining technology. what's going on? Why do rabbits suddenly stop using this technology?

The 30-micron precision machining technology, although we have eliminated it, but... don't you have it?

You're sharpening your knives, why don't you come and get knives?

At the same time, buyers looking for high-precision machining technology on the international black market all disappeared for a while.

A lot of people who were about to use the elimination technique to slaughter the rabbits were horrified and couldn't understand the situation at all.

"News from this 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."

"The successful development of this technology marks that my country has reached the world's leading level in high-precision machining technology!"

As soon as the news came out, the domestic reaction was flat.

Professor Lu is leading the world again. Well, this is the basic operation.

There was an uproar abroad.

What the hell! The high-precision processing technology of the flower gardener has actually achieved an error of no more than one micron?

We are still struggling in the ten micron range, why are you at one micron?

And... is that Professor Lu again?

You are a genetic scientist, what kind of high-precision processing technology do you research? It's not business, you know what?
