Chapter 337 Robotic Arm Thesis Defense?

"We will add additional funds this year. It is conservatively estimated that we will invest 100 billion in the next two years."

Gulu.

Someone swallowed unconsciously.

Zhou Jianping said with a kind expression: "Let's talk about this matter after the inspection and review are completed. After all, things have priorities. However, I believe that some experts who are suffering from insufficient R&D funds or insufficient equipment functions may be interested."

At this point, Gu Qing also understood that this topic was over.

He knows what is happening in some research institutes in Daxia now.

Most ordinary researchers do not have project funds. Some of the high-end equipment required for unpopular projects is shared with other research institutes. 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 is a land of vast resources, it is also rich in human resources.

When there are more people, there will inevitably be garbage, which is why the phenomenon of xue valves occurs.

But this kind of thing cannot be completely cleaned up, after all, the human heart is difficult 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 the robotic arms one after another.

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

This triggered a series of low-pitched exclamations from the expert group.

"The robotic arm using a pneumatic honeycomb structure in the Harbin Institute of Technology Research Institute is actually at least two versions behind yours?"

"Something's wrong. The color of this metal is definitely not ordinary metal. It's newly developed? How is the ductility? How is the hardness? What about the plasticity?"

"How do you control so many joints?"

Zhang Tianhao and others were answering the questions in real time. However, because they involved confidential content, many of the answers were written in a single brush stroke, causing many middle-aged experts to frown and think again and again.

Zhou Jianping was looking at it with admiration at first, but it wasn't until Gu Qing led him to the front of the robotic arm for the aerospace industry that was the focus of the day and informed him of the parameters that he became emotionally moved.

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

My family knows their own affairs.

The most advanced robotic arm on the surface today is the Canadian robotic arm used in Europe and the United States, which has six joints. Daxia independently developed a robotic arm with seven joints, which is already the best in the industry.

But Jiuzhou Technology actually developed a nine-joint robotic arm. How is this possible?

Gu Qing smiled and nodded.

"The six joints of the Canadian robotic arm were the technical limitation at the time. I believe we are definitely moving towards the development of seven joints. After all, a robotic arm with 6 degrees of freedom cannot maintain the three-dimensional position of the end mechanism unchanged in space. Change from one configuration to another.

Just like a person rotating a bottle cap with his hand, an arm with six degrees of freedom is like having no wrist and requires the entire body to rotate the bottle cap, while an arm with seven degrees of freedom has a wrist joint and can adjust the rotation through the wrist.

In order to achieve a higher degree of freedom, the robotic arm we developed has been upgraded to nine joint degrees of freedom. "

Zhou Jianping frowned slightly when he heard this, and said: "Since you know the similarity between the robotic arm and the human arm, you should also know that the many joints in the human body and the robotic arm can not only increase the degree of freedom, but also bring More shortcomings, and this metaphor is not qualified. Rotating the bottle cap can actually be achieved with five joints.

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

It's a bit like a thesis defense. The chief designer is like a demanding tutor launching a series of deadly questions. Seeing this attitude, if Gu Qing can't give a practical answer, not only will the robotic arm project fail, but the poaching operation discussed earlier may also be lost. .

After all, companies that do not have deep and practical project research and development will not be able to attract the attention of big bosses.

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

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

After all, humans are carbon-based creatures, but robotic arms are mechanical creations. Bearing rotation, hinge rotation, and ligaments and joints are not 100% consistent.

As for the problem of poor rigidity of the robotic arm caused by the high degree of freedom, we have 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&D laboratory or our aerospace industry.

Secondly, having too many joints leads to poorer control and adjustability. Our titanium-tantalum department’s bionic mechanical prostheses have gained considerable experience in many users’ personal customization projects, and have developed their own unique drive operation program and intelligent operation technology. This problem can be solved perfectly. "

After giving a clear and logical answer, Gu Qing immediately made a decisive move.

"Actually, having said all that, no matter how beautiful the parameters are, they can't compare to the actual hands-on experiments. Why don't we go to a large vacuum laboratory to experience it?"

After hearing this, Zhou Jianping knew that Jiuzhou Technology was indeed technologically capable.

A vacuum laboratory that can run such large equipment is not something that can be built with millions or tens of millions of Xia Yuan. Some of NASA's testing work is carried out in a vacuum laboratory on the ground. Although there is no major technical barrier, this thing is expensive and material-consuming.

It is a must for doing practical things and is a typical example of cheating subsidies.

However, although they know that the other party has something, Daxia scientists are stubborn and can only recognize it when they see, touch, and use it.

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

Luo Yunjia was waiting outside the underground vacuum laboratory. When he saw Gu Qing coming with a group of people, he walked forward.

"Teacher, the robotic arm has been placed inside. It uses wireless control. The operating table is next door. Should we evacuate the vacuum now?"

Gu Qing nodded slightly and 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 needed for the space capsule are naturally more technologically advanced and more difficult to operate than those used in ordinary life.

While vacuuming here, they are teaching the operation there.

After all, Jiuzhou Technology's R&D system and equipment have deviated from the normal model of other laboratories on Earth.

PS: Write a little more detailed. When I looked at the calendar today, I was a little happy when I found that I had attended all the classes this month and had not taken any leave.

Then I wanted to slack off for a day.

But when I saw that there were so many monthly tickets and recommendation tickets in the background, I was not sleepy in an instant.

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

November is over, and I'll leave the voting for December to you all. I will be fully present and even add more thanks!

Good night everyone~
