After Kangchi completed the acceptance of the Pangu base, the originally quiet Screen Mountain suddenly became lively.

Trucks full of trucks are constantly carrying all kinds of instruments, equipment and materials, some of which have been moved from Datang Heavy Industries, and some are new equipment that has been booked in advance.

After a few days of major relocation, the Pangu base finally quieted down, and only a few hundred senior engineers from Datang Heavy Industries remained here to assist Kangchi in installing and debugging the equipment.

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

At present, Kangchi is only using 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 couldn't help frowning slightly.

Although this drawing had obviously been modified, Yan Hui still recognized it at a glance that this was the robotic arm they used in the battery swap station.

It's just that on the basis of that, Kangchi has added a mobile platform and a manipulator replacement module.

Moreover, the robotic arm is a product provided by Shenyang SIASUN Automation Company, Datang Heavy Industries does not have drawings, and Kangchi just imitates their design and makes a lot of simplifications.

Performance and precision, obviously a few levels lower than theirs.

Yan Hui couldn't help but ask suspiciously: "If you just want to add the replacement module of the mobile platform and the manipulator, why don't you just ask SIASUN to customize?" ”

Customize?

I want to too, but I didn't make it myself, so I can't upgrade it......

Kang Chi silently complained in his heart, and then explained seriously: "Intelligent manufacturing robot technology is very important to the future industrial development, so I plan to personally start from the most basic technology to imitate and verify, and then continue to improve to create an industrial robot that can undertake the automatic manufacturing and assembly of precision parts." ”

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

Can you automate the manufacturing and assembly of precision parts?

How advanced industrial robots do you need to do this?

Although many factories, especially on the assembly lines of automobile manufacturing plants, are using a large number of industrial robots to replace workers, it 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 what each industrial robot can complete is only a certain process on the assembly line.

In other words, they're just doing very repetitive movements, just with a higher level of precision.

But through this drawing of Kangchi and the meaning expressed in the words, Yan Hui can clearly feel that Kangchi's purpose is to create a more 'versatile' industrial robot, and the difficulty can be imagined.

And......

"If this thing is really made, won't the factory completely use ordinary workers in the future?"

"It still depends on the cost." Kang Chi explained with a smile, "Even if I build it, but the cost of one is tens of millions or even hundreds of millions, it is definitely better to use labor." ”

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

The main thing is that he has become superstitious about Kangchi's technology,

In Yan Hui's view, there seems to be nothing Kangchi wants to do, but can't do.

So cost, is it really going to be an issue?

Yan Hui strongly suspects that this is actually just a pretext for Kangchi,

He probably didn't want to see such a high-tech thing enter society too early and too quickly, thus causing a large number of workers in society to lose their jobs.

Yan Hui's worries and speculations 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 early.

Before he has engaged in projects such as 'big technology infrastructure', which can create massive job opportunities, there is no need for this.

However, to build large-scale scientific and technological infrastructure, in fact, it is necessary to greatly improve the knowledge and skill level of the whole people and the overall economic prosperity of the society.

Otherwise, if it is forcibly started, it will cost the people and money, and the spectacle will mislead the country......

Therefore, Kangchi is making this thing now, simply 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 was at the Pangu base, leading Yan Hui and hundreds of engineers to manufacture the first generation of industrial robots.

Because the technical level of this robot is relatively low, it belongs to the 'technical verification' machine in Kangchi's mouth, so for Yan Hui, a scientific research team that has been outstanding even if it looks at China, it is basically not difficult, and it was manufactured in only three days.

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

In the Pangu base of Nuoda, Kangchi was soon left alone.

Looking at the four-meter-tall industrial robot in front of him, with two robotic arms and a crawler mobile platform, for people like Kangchi, who have a unique love for mechanical equipment, it is just like seeing a beautiful woman.

[PS. If you have time in the future, I will try to use AI to match a picture for everyone, of course, AI drawing is a bit silly, it must not be able to fully present the desired effect, and it takes a lot of time to debug, so let's make do with it first~]

Upgrade!

General experience - 10000.

A white light flashed, and the shape of this industrial robot changed slightly, the whole became slightly slender and flexible, and the entire track was also separated into two sections, and the excitement and flexibility have been improved to a certain extent.

Kangchi's requirement for this industrial robot is to be able to copy at least a level 1 technical verification machine on its own, which basically meets his current needs.

Instead of continuing to upgrade, Kangchi conducted a test first.

However, the test results are not ideal, the processing accuracy of the 2-level industrial robot on the steel plate and other materials of the material is only ±1.0mm, and the assembly accuracy is ±0.1mm.

So Kangchi had to continue to upgrade, until it was upgraded to level 4, this industrial robot finally met the requirements of Kangchi, and could manufacture and assemble a first-class industrial robot alone according to the drawings.

Moreover, this industrial robot, the prefix is also added with the word low-level intelligence, which can simply understand Kangchi's instructions, such as faster, slower, and move up 0.01mm and other specific instructions.

In fact, Kangchi is a little cautious about the word 'intelligence', after all, the intelligence defined by the system and the intelligence currently defined by humans are probably not the same dimension.

For example, the intelligent robot in the industrial field is actually just collecting various data through various sensors, and then running according to the program logic, which is essentially just a more powerful machine, and it is impossible to have its own thinking ability in principle.

Even chatGPT's so-called logical thinking ability is only based on the prediction and calculation of big data, not based on thinking and consciousness, and it can be regarded as a search engine, but it is more accurate and can reorganize and arrange information more logically.

Therefore, artificial intelligence with real independent thinking and consciousness is still far from the current level of human science and technology.

But in Kangchi's system, it's not easy to say......

Therefore, when the entire Pangu base was being built, Kangchi once put forward a request, that is, to install a set of ESP emergency system, which can paralyze the electronic equipment of the entire base in case of a special emergency, and the switch of this system is only available to him.

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

In fact, it is not an exaggeration to call the motor the cornerstone of the electric age in the science and technology of the entire civilization.

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

For example, children's electric toys, air conditioning compressors, computer hosts, mobile phone vibration motors, lithography machine workpiece platforms, etc., anything involving sports, even the smallest things, must have a motor.

Magnetism and electricity have been mutually beneficial from the very beginning, and motors are the most direct embodiment of human beings' ability to use magnetism and electricity.

Including the ignition of controllable nuclear fusion stellar simulator and tokamak, the main test is also the ability of human beings to master electromagnetism, it is no exaggeration to say that as long as you master magnetism and electricity, you will master the future.

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

The earliest motors used in electric vehicles are basically asynchronous induction motors, and its rotor is a squirrel cage-like structure made of conductive metal bars, when the stator coil is energized, the three-phase alternating current inverted from the battery will produce a rotating magnetic field RMF, and the metal bars of the squirrel cage 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, and the torque will be sharply reduced after exceeding a certain speed, which is the main reason for the high-speed weakness of some electric vehicles.

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

The rotor of the permanent magnet synchronous motor rotates under the drive of the stator magnetic field according to the principle of opposites attracting, which can provide greater starting torque and does not waste energy in the rotor.

However, because the permanent magnet synchronous motor will produce a back EMF, and the higher the speed, the stronger the back EMF, so the problem of high speed weakness still exists.

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

The synchronous reluctance motor does not have permanent magnets, it is by opening several arc slots in the middle of the iron rotor, using magnetic field extrusion to make the rotor rotate, and this design will not produce back electromotive force, and the high-speed performance is very strong.

But synchronous reluctance motors have a fatal drawback:

The vibration was loud......

Therefore, Toyota's engineers and designers combined the permanent magnet synchronous motor with the synchronous reluctance motor, directly stuffed the permanent magnet into the groove in the middle of the rotor, reduced 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 kind of motor used on the Toyota Prius.

It's just that the effect is average.

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

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

And in this regard, Toyota is obviously inferior to Tesla.

On the basis of this principle, Tesla built the IPM-SynRM and first installed it on the Model S Plaid, which directly increased its top speed to an astonishing 322KM/H and a horsepower of 1020 horsepower.

directly stunned Toyota.

Tesla's use in the Semi truck is actually this IPM-SynRM motor, but there are only three of them.

When Kangchi designed the motor for the truth, in order to leave a higher upgrade space for the future, it also referred to this design.

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

"Okay!"

The industrial robot named Bai Niu by Kangchi, the four tracks suddenly rotated flexibly, easily opened the iron box, and took out the motor inside and put it in front of Kangchi.

Kangchi couldn't help but nodded: "Not bad, not bad." ”

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

And it's free.

"Thank you, host, for the compliment."

Do you even know how to reply?

This low-level intelligence doesn't feel low-level.

"Do you know why you are called a white girl?"

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

"Well, that's right, I'm a little scared if you can answer me......"

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

“……”

"You're still on standby, don't answer if you don't tell you, I don't want to say a word and you can't recognize the ......instruction every time you say it."

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

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

looks

How do you feel a little pathetic?

Kangchi shook his head and looked at the motor in front of him,

[Item: Built-in permanent magnet synchronous reluctance motor]

【Manufacturer: Datang Heavy Industries】

When designing this motor, Kangchi did not open it, and it was completely he and Datang Heavy Industries' R&D personnel who hardened it in just over ten days, so the performance was much lower than that of IPM-SynRM.

However, this performance is not only enough for the truth, but also very good in the national electric vehicle market.

Anyway, it's much better than the one used in Qirui's own electric car.
