Technological power starts with upgrading lenses

After Kangchi completed the acceptance of Pangu Base, the originally peaceful Pingfeng Mountain suddenly became lively.

Fully loaded trucks were carrying various instruments, equipment and materials in an endless stream. Some of them were moved directly from Datang Heavy Industry, and some were new equipment that had been booked in advance.

After several days of large-scale relocation, the Pangu Base finally gradually quieted down. Only a few hundred senior engineers from Datang Heavy Industries remained here to assist Kangchi in installing and debugging equipment.

Although this wave of battles looks huge, in fact the entire Pangu base is divided into three floors, with 4 large-scale assembly workshops, 18 small and medium-sized workshops, and hundreds of various material warehouses.

Kangchi currently uses only one medium-sized workshop and three small workshops.

When the equipment was almost installed, Kang Chi called Yan Hui over, took out a drawing and said, "You guys stay here for the next two days and help me build this thing."

Yan Hui took the drawing, looked at it carefully, and then frowned slightly.

Although the drawing had obviously been modified, Yan Hui recognized it at a glance. This was the type of robotic arm they used at the power swap station.

It's just that Kangchi added a mobile platform and manipulator replacement module based on it.

Moreover, that robotic arm was a product provided by Shenyang Xinsong Automation Company. Datang Heavy Industry did not have drawings. Kangchi just copied their design and made a lot of simplifications.

The performance and accuracy are obviously several levels lower than theirs.

Yan Hui couldn't help but asked doubtfully: "If you just want to add replacement modules for the mobile platform and manipulator, why not just go to SIASUN to customize it?"

custom made?

I think so too, but since I didn’t make it myself, I can’t upgrade it…

Kang Chi complained silently in his heart, and then explained seriously: "Intelligent manufacturing robot technology is crucial to future industrial development, so I plan to personally imitate and verify the most basic technology, and then continue to improve it to create something that can Industrial robots responsible for automatic manufacturing and assembly of precision parts.”

After Yan Hui heard this, his expression suddenly became serious.

Can precision parts be automatically manufactured and assembled?

How advanced an industrial robot can do this?

Although many factories, especially the assembly lines of automobile manufacturing factories, now use industrial robots to replace workers, which can not only greatly improve production efficiency and accuracy, but also reduce labor costs.

But in fact, there are many types of industrial robots on an assembly line, and each industrial robot can only complete a certain process on the assembly line.

In other words, they are just performing very repetitive actions, but with relatively high precision.

But through Kangchi's drawing and the meaning expressed in his words, Yan Hui could clearly feel that Kangchi's purpose was to create a more 'universal' industrial robot. The difficulty can be imagined.

and……

"If this thing is really made, wouldn't the factory no longer need ordinary workers at all?"

"It still depends on the cost." Kang Chi explained with a smile, "Even if I build it, but the cost of one machine is tens of millions or even hundreds of millions, it is definitely not as good as using labor."

Yan Hui nodded, but he couldn't hide his worry.

The main reason is that he has become superstitious about Kangchi's technology.

From Yan Hui's point of view, there seemed to be nothing that Kang Chi wanted to do but couldn't.

So, is cost really a problem?

Yan Hui strongly suspects that this is actually just Kang Chi's excuse.

He probably doesn’t want to see such high-tech things enter society too early or too quickly, causing a large number of workers in the society to lose their jobs.

Yan Hui's worries and guesses were correct.

Although according to the current trend of technological development, this day will come sooner or later, Kangchi can also make this day come earlier.

There was no need for this before he embarked on a project like "big technology infrastructure" that could create massive job opportunities.

However, the construction of large-scale science and technology infrastructure must actually be based on the premise that the knowledge and skills level of the entire population has been greatly improved and the overall social economy is relatively prosperous.

Otherwise, it would be a waste of people, money, and a spectacle that would ruin the country...

Therefore, Kangchi is building this thing now purely to serve itself, and in order to control this technology, cost and non-replicability are the best excuses.

So in the next few days, Kangchi led Yan Hui and hundreds of engineers to build the first generation of industrial robots at the Pangu base.

Since the technical level of this robot is relatively low and it is what Kang Chi calls a 'technical verification' machine, it is basically not difficult for Yan Hui's scientific research team, which is already outstanding even if they look at China. The sky is finished.

After a simple test to confirm that its performance was similar to the drawing design, Kangchi asked Yan Hui to take people back to Datang Heavy Industries to continue expanding the motor production line.

Kang Chi was soon the only one left in Nuo Da's Pangu base.

Looking at this four-meter-high industrial robot with two robotic arms and a crawler-type mobile platform, for a person like Kang Chi who has a unique love for mechanical equipment, he just feels like seeing a beautiful woman. Very pleasing to the eye.

[PS. If I have time in the future, I will try my best to use AI to provide you with a picture. Of course, AI drawing is a bit silly, and it will definitely not fully show the desired effect, and debugging is very time-consuming. Let’s just make do with it~]

upgrade!

General experience - 10000.

A flash of white light flashed, and the shape of the industrial robot changed slightly. It became slightly more slender and flexible. The entire track was also separated into two sections, and the flexibility was improved to a certain extent.

Kangchi's requirement for this industrial robot is that it can at least replicate a level 1 technology verification machine on its own, which will basically meet his current needs.

Kangchi did not continue to upgrade, but conducted some tests first.

However, the test results are not ideal. The processing accuracy of level 2 industrial robots on steel plates and other materials is only ±1.0mm, and the assembly accuracy is ±0.1mm. It is definitely no problem to build cars with this accuracy, but it is still not possible to build robotic arms. It needs Assembly can be completed with the assistance of Kangchi.

So Kangchi had no choice but to continue upgrading. It was not until it reached level 4 that this industrial robot finally met Kangchi's requirements and could independently manufacture and assemble a first-level industrial robot according to the drawings.

Moreover, this industrial robot has the word "low-level intelligence" added to the prefix. It can simply understand Kangchi's instructions, such as faster, slower, move up 0.01mm and other specific instructions. How intelligent it is depends on how smart it is. Kangchi needs to explore further.

In fact, Kangchi is a little cautious about the word "intelligence". After all, the intelligence defined by the system is probably not the same dimension as the intelligence currently defined by humans.

For example, the current intelligent robots in the industrial field actually only collect various data through various sensors and then run according to program logic. In essence, they are just a more powerful machine. In principle, they cannot have their own thinking ability. .

Even the so-called logical thinking ability of chatGPT is only based on big data prediction and calculation, rather than thinking and awareness. It can be regarded as a search engine, but it is more accurate and can analyze information more logically. It’s just a sexual reorganization and arrangement.

Therefore, artificial intelligence that truly has independent thinking and consciousness is still far from the current technological level of mankind.

But in Kangchi's system, it's hard to say...

Therefore, when the entire Pangu base was being built, Kangchi once made a request, that is, to install an ESP emergency system. In the event of a special emergency, the electronic equipment of the entire base can be paralyzed, and the switch of this system is only He just has it.

After getting the industrial robot, the next step is to get the motor.

In fact, it is no exaggeration to call the motor the cornerstone of the electric age in the technology of the entire civilization.

As long as it is something that uses electricity, except for lighting, everything else is basically inseparable from the motor.

For example, children's electric toys, air-conditioning compressors, computer hosts, mobile phone vibration motors, photolithography machine workpiece platforms, etc. Anything that involves movement, no matter how small, must have a motor.

Magnetism and electricity have been in a mutually beneficial relationship from the beginning, and motors are the most direct manifestation of human beings' ability to utilize magnetism and electricity.

The two technical routes, including the stellarator and tokamak that ignite controllable nuclear fusion, mainly test human beings' ability to master electromagnetism. It is no exaggeration to say that as long as you master magnetism and electricity, you will control the future.

However, those things are still too far away. Kangchi’s current main task is to solve the problem of high-torque motors on heavy-duty trucks as soon as possible.

The earliest motors used in electric vehicles were basically asynchronous induction motors. Its rotor was a squirrel-cage structure made of conductive metal strips. When the stator coil was powered on, the three-phase inverter from the battery Alternating current will produce a rotating magnetic field RMF, and the squirrel cage metal strips will cut the rotating magnetic field.

However, the asynchronous induction motor induces the current in the rotor, which consumes 3-4% of the energy. The energy conversion rate is low, and the starting torque is not strong enough. After exceeding a certain speed, the torque will decrease sharply. This is why some electric vehicles are weak at high speeds. main reason.

In order to solve these problems, researchers invented the permanent magnet synchronous motor, which is now used in most domestic electric vehicle models.

The rotor of the permanent magnet synchronous motor rotates under the magnetic field of the stator based on the principle of opposite poles attracting each other, which can provide greater starting torque without wasting energy in the rotor.

However, because the permanent magnet synchronous motor generates a counter electromotive force, and the higher the speed, the stronger the counter electromotive force, so the problem of high speed fatigue still exists.

In order to solve the high-speed problem and further increase the torque, Toyota engineers first thought of the synchronous reluctance motor.

Synchronous reluctance motors do not have permanent magnets. They open several arcuate slots in the middle of the iron rotor and use magnetic field extrusion to rotate the rotor. Moreover, this design does not generate back electromotive force and has strong high-speed performance.

But the synchronous reluctance motor has a fatal shortcoming:

The vibration is great...

So Toyota engineers and designers combined the permanent magnet synchronous motor with the synchronous reluctance motor, directly stuffing the permanent magnet into the slot in the middle of the rotor, reducing the interaction between the permanent magnet magnetic field and the stator coil, and invented the built-in Permanent magnet synchronous reluctance motor.

This design has both the low-speed torque of the permanent magnet synchronous motor and the high-speed torque of the synchronous reluctance motor.

This is the type of motor used in the Toyota Prius.

However, the effect is average.

Because everyone actually understands the principle. The only difference is who can maximize the performance of this designed motor through exquisite system control and excellent industrial manufacturing capabilities.

In addition, the performance of the magnet and electromagnetic coil wire materials has a crucial impact on the performance of the motor.

In this regard, Toyota is obviously not as good as Tesla.

Based on this principle, Tesla created the IPM-SynRM and first installed it on the Model S Plaid, directly increasing its top speed to an astonishing 322KM/H, and the horsepower is as high as 1,020 horses.

It completely confused Toyota.

What Tesla uses in its Semi truck is actually the same IPM-SynRM motor, but three of them are installed.

When Kangchi designed the motor for Guizhen, in order to leave more room for future upgrades, they also referred to this design.

Kang Chi pointed to an iron box and said to the industrial robot: "Bainiu, take out the motor inside and put it in the open space in front of me."

"OK!"

The four tracks of the industrial robot named Bai Niu by Kang Chi suddenly started to rotate flexibly. It easily opened the iron box, took out the motor inside and placed it in front of Kang Chi.

Kang Chi couldn't help but nodded: "Not bad, not bad."

Without Fang Qiming, a stronger girl came to help lift the steel plate.

And it's free.

"Thank you for the compliment, Master."

You actually know how to reply?

This low-level intelligence doesn’t feel low-level either.

"Do you know why I call you Bai Niu?"

Bai Niu was stunned for a moment before replying: "Sorry, I can't recognize the command."

"Well, that's right. I would be a little scared if you could answer..."

"Sorry, I don't recognize the command."

"..."

"You'd better wait by the side. Don't answer unless I call you. I don't want you to reply that you can't recognize the command every time I say something..."

"Okay, master, please rest assured. I will remain silent when encountering unrecognizable instructions in the future."

After Bai Niu finished speaking, she obediently walked to the wall and entered standby mode.

It seems,

Why do you feel so pitiful?

Kang Chi shook his head and looked at the motor in front of him.

When designing this motor, Kangchi did not cheat. He and the R\u0026D personnel of Datang Heavy Industry came up with it in just more than ten days. Therefore, the performance is much lower than that of IPM-SynRM.

However, this performance is not only sufficient for Gui Zhen, it is also absolutely excellent in the national electric vehicle market.

Anyway, it’s much better than the one used in Qirui’s own electric vehicles.
