"This year we will add additional funds, and it is conservatively estimated that we will invest hundreds of billions in the past two years."

grunt.

Some people swallowed their saliva unconsciously.

Zhou Jianping looked kindly and said: "Let's talk about this matter after the inspection and review. After all, there are priorities, but I believe that some experts who suffer from insufficient research and development funds or poor equipment functions may be moved."

Speaking of this, Gu Qing also understands this topic, so I will stop here.

He knows what's going on in some research institutes in Daxia.

Ordinary researchers mostly don’t have project funding. Some unpopular projects require high-end equipment that is shared with other research institutes, and some individual equipment is simply not available. There are only a few in the world, and none of them can be exported to Daxia.

While Daxia has a vast land and resources, it is also rich in human resources.

When there are too many people, there will inevitably be garbage, so there will be a phenomenon called blood valve.

But this kind of thing cannot be completely cleaned up, after all, people's hearts are hard to figure out.

The communication between the two parties returned to a harmonious atmosphere.

Gu Qing led the experts who came from afar to look at one mechanical arm after another.

From large-scale industrial robotic arms with rather rough shapes, to high-precision research and development robotic arms with fine joints, to robotic arms with different shapes that are used in various special industries and different environments.

It caused the expert group to exclaim in a low voice.

"The mechanical arm using the pneumatic honeycomb structure in the research institute of Harbin Institute of Technology is actually at least two versions behind yours?"

"What's wrong, this metal color is definitely not ordinary metal, it is newly developed? How is the ductility? How is the hardness? What about the plasticity?"

"With so many joints, how do you manage to control them freely?"

Zhang Tianhao and others were answering in real time, but because of the confidentiality involved, many of the answers were summed up in spring and autumn, which made many middle-aged experts frown and think again and again.

At the beginning, Zhou Jianping still looked at it with admiring eyes. It was not until Gu Qing led it to the front of the robotic arm used in the aerospace industry and told him the parameters that he was moved.

"The Canadian arm only has six joints, but the robotic arm you developed actually has nine joints?"

My family knows my own affairs.

Now the most advanced robotic arm on the surface is the Canadian robotic arm used in Europe and the United States, with six joints. And Daxia independently developed a robotic arm with seven joints, which is already at the top of the industry.

But Kyushu Technology actually produced a nine-joint robotic arm, how is this possible?

Gu Qing smiled and nodded.

"The six joints of the Canadian robotic arm was a technical limitation at the time. I believe we must be moving towards the development of seven joints. After all, a robotic arm with six degrees of freedom cannot keep the three-dimensional position of the end mechanism unchanged in space. change from one configuration to another.

Just like a person rotates a bottle cap by hand, the six-degree-of-freedom arm seems to have no wrist and needs the whole body to drive the rotating bottle cap, while the seven-degree-of-freedom arm has a wrist joint that can mediate the rotation through the wrist.

For a higher degree of freedom, the robotic arm we developed has been overcoming R\u0026D and upgraded to nine joint degrees of freedom. "

Zhou Jianping frowned slightly when he heard the words, and he said: "Since you know the similarity between the robotic arm and the human arm, you should also know that the joints of the human body and the robotic arm can not only improve the degree of freedom, but also bring more freedom. There are more shortcomings, and this metaphor is not qualified. In fact, all five joints of the rotating bottle cap can be realized.

How to deal with the overall structure of the robotic arm? How to deal with the rigidity of the robotic arm body? There are too many joints, how to control and adjust? "

It's a bit like a thesis defense, the chief designer is like a harsh mentor launching a series of life-threatening questions. Seeing this posture, if Gu Qing can't give a real answer, not only the robotic arm project will fail, but also the poaching operation discussed earlier may be gone. .

After all, an enterprise whose project development is not deep and practical will not be able to catch the eyes of the boss.

After sorting out his thoughts for a while, the young Boss Gu said: "I didn't think about this analogy. From a scientific and serious point of view, the human arm joints are similar to mechanical joints, but they do have very different movement restrictions.

The drive motors used are different, and the joint movement of the robotic arm is more flexible than that of the human arm, so the degree of freedom is also the same.

After all, human beings are carbon-based organisms, but the mechanical arm is a mechanical creation, and the bearing rotation, hinge rotation, ligaments, and joints are not 100% appropriate.

As for the high degree of freedom that leads to the deterioration of the rigidity of the robotic arm, we also overcome it through the development of new metal materials.

However, new materials consume much more energy and materials than ordinary special metals, and cannot support mass production, so they can only be supplied to our R\u0026D room or our aerospace industry.

Secondly, the number of joints will lead to poor control and adjustment. The bionic mechanical prosthetics of our titanium tantalum star department have gained considerable experience in the personal customization projects of many users, and have developed their own unique driving programs and intelligent operation technology. Can perfectly solve this problem. "

After a clear answer, Gu Qing directly came up with a lore.

"Actually speaking so much, no matter how good-looking the parameters are, it can't compare with the actual manual experiment. Why don't we go to a large vacuum laboratory to experience it?"

Hearing this, Zhou Jianping knew that Kyushu Technology was indeed capable of technology.

A vacuum laboratory capable of operating such a large-scale equipment is not something that can be built by tens of millions of dollars. Some of NASA's testing work is carried out in the vacuum laboratory on the ground, although there is not much technology Barriers, but this thing consumes money and materials.

It is one of the typical cases where it is necessary to do practical things and the subsidy is too bad.

However, even though they knew that the other party had something, the Daxia scientists had a stubbornness, and they could only recognize it when they saw, touched, and used it.

The group left the laboratory again and took the underground elevator to go deeper underground.

Luo Yunjia was waiting outside the door of the underground vacuum laboratory, and when she saw Gu Qing bringing a group of people over, she stepped forward.

"Teacher, the robotic arm has been placed inside, and it is controlled wirelessly. The operating table is next door. Do you want to vacuum it now?"

Gu Qing nodded slightly, then turned to look at Zhou Jianping.

"Shall we start now?"

The latter nodded.

The ground environment simulation test of various spacecraft is an important means to ensure the reliable operation of the aircraft. After all, in the vacuum environment and weightlessness in space, many materials and equipment will be damaged.

Therefore, the accuracy and reliability of the ground space ring model test will directly affect the performance inspection and assessment of aerospace equipment, and the robotic arms used in the space capsule are naturally more technologically advanced than the robotic arms used in ordinary life. It is also more difficult.

Vacuuming here, teaching operation over there.

After all, the R\u0026D system and R\u0026D equipment of Kyushu Science and Technology have deviated from the normal model of other laboratories on the earth.

PS: I wrote it in a little more detail. Looking at the calendar today, I found that I was a little happy when I was fully present this month and didn’t ask for leave.

Then I wanted to fish for a day.

But when I saw that there were so many monthly tickets and recommended tickets in the background, I didn't feel sleepy in an instant.

Thank you for your recommendation tickets and monthly tickets, thank you book friend 51031 for your 100 starting point reward, and thank you Xiaoshan Xiaoshan for your very smart 100 starting point reward.

November is over, please vote for December, I will be fully present and even more grateful!

good night everyone~
