Technology: breaking the hegemony that monopolizes the world

"The interface on the left is the display and control operation interface of the robotic arm, which can be operated using commands or smart targets. If necessary, astronauts can also step out of the space capsule and use some hardware to operate.

In order to ensure that the manipulator operators can efficiently complete the operation of the manipulator, we independently developed modeling software to establish a manipulator model, used Qt to build a control interface for controlling the movement of the manipulator, combined with a 3D rendering engine to establish a virtual simulation environment, and completed the entire project. The display and control interface is built to observe the state of the manipulator in the simulation environment through the value of the joints of the manipulator.

After long-term test optimization, the display and control interface can now meet the basic requirements of the manipulator operator to precisely control the manipulator.

The interface on the right is the numerical operation interface of the thermal vacuum test. In order to better verify the various performance and function tests of the spacecraft and its components, we have added some special equipment during the temperature change process of cold soaking and hot soaking. "

Zhou Jianping was studying on the sidelines, and his demeanor was quite calm.

However, a certain expert surnamed Wang in the team was not calm.

Wang Qilu helped his glasses frame, stared at the operation interface, and then at the real-time video of the underground vacuum laboratory on the big screen, rubbing his hands itchy.

...

Facts have proved that the tenacity of scientific research workers in Daxia can be reflected everywhere.

The minimum age in this expert group is thirty-nine years old, and the others are around fifty years old.

Middle-aged people are like young people playing a large-scale simulation game, addicted to it, and never get tired of it.

A group of people surrounded the operator, and when the test session was over, they rushed away, and then the next one rushed forward.

After you play, I will appear on stage.

It's just that the capital investment of this simulation game is literally hundreds of millions of Xia Yuan, and it can only be played by a limited number of people, so it is destined not to be popularized on a large scale.

All the husbands chatted about being teenagers, left the data, and right the practical operation.

This time I played from morning to afternoon.

Lunch is a nutritious meal packed and delivered from the cafeteria.

They are all industry experts, and they are all successful people.

One by one holding a box lunch, watching the experiment video and experiment data with relish.

Lao Wang gnawed on the purple sweet potato, and said: "The ground operators control the robotic arm through the visual interface, and the software on these control panels can clearly display and change the angle between the robotic arms.

Generally, controlling the parameters of the manipulator requires the operator to be very familiar with how to adjust each manipulator, but the learning cost of this system is very low. According to my estimation, this system can be competent even for future lunar surface sampling tasks, and it can improve the control of mechanical arm efficiency. "

There is much appreciation between words.

However, Zhou Jianping, the chief designer of the manned spaceflight project, thought more about it.

"Ground operators need to face the complex and special terrain of the lunar surface during the remote operation mission. From the perspective of the operator's vision, the display and control interface of Kyushu Technology can clearly present the geographical information of the remote site and the status of the remote control equipment. The operator needs to control the movement of the robotic arm through the display and control interface, and change the position and rotation angle of the robotic arm.

The human-computer interaction of space teleoperation tasks is inseparable from two aspects: visualization equipment and control of remote equipment. In their system, the visualization equipment uses a high-quality OLED large screen, and visual information such as environmental information and the motion status of the robotic arm on the detector is presented on the computer display screen through the camera carried by the robotic arm; The control uses the mouse, keyboard or remote sensing to control the movement of the robotic arm on the detector.

It has to be said that in this system, the accuracy of program design, screen display quality and environmental information collection and modeling is very high. "

Some experts suddenly realized: "Jiuzhou Technology's sweeping robot is using this set of environmental information collection and modeling technology, and these display screens are also independently produced by them, so it seems that they have made achievements in this area very early."

This is the case with science, and advanced technologies are often applied in the simplest life scenarios.

In the 1990s, NASA's Jet Propulsion Laboratory developed a satellite camera that was reduced in size but not too weak in function according to requirements. Of course, this technology is also used in today's mobile phone/computer cameras.

And our wireless bluetooth headset, which was originally developed to communicate with astronauts in outer space.

Other products such as solar cells, diapers, and dehydrated vegetables are basically derived from the technical transformation of aerospace project achievements.

Full and busy, the sun is setting.

Everyone who stayed in the underground laboratory for most of the day finally returned to the ground.

Zhou Jianping also had a decision in his heart - this good thing must be obtained!

The robotic arm of Kyushu Technology can not only realize the crawling function of the cabin through the docking and separation between the end effector and the target adapter, and reach the outer surface of each cabin of the space station in a wider range, but also the accuracy is high enough to carry out space station construction tasks.

There's nothing more to say, let's talk about the terms.

He is ready to grant the money.

However, Gu Qing's reply was intriguing.

"Provide three space station robotic arms for free, and provide three more space station robotic arms for free within two years, and provide maintenance and upgrades at cost prices, in exchange for satellite launches and space experiment quotas within the rules?"

At first glance, this is a big bargain, after all, Kyushu Technology has never sold such a high-precision robotic arm to any non-shareholding company.

But satellite launch qualifications and space experiment places are not cheap.

Although it is said that the green light must be complied with the rules, these things are really a radish and a pit, and they have been lined up long ago.

Seeing that the boss didn't refuse immediately, but was thinking about it, Gu Qing knew that this time it should be safe.

He went on to say: "This type of robotic arm can also participate in the capture of visiting hovering aircraft, transfer the load of cargo spacecraft, check the status of the cabin table outside the space station, assist astronauts to go out of the cabin, and realize the mechanical arm cascade with the experimental cabin. combination.

And can accept custom program modification. "

...

The air suddenly condensed.

Zhou Jianping took a deep look at the young man, and looked at Gu Qing a little nervously, and then looked away.

After a while, he sighed with emotion.

"Sure enough, there are talented people from generation to generation. I am really amazed that you can achieve such a big breakthrough in such a short period of time. I will negotiate with the relevant departments to coordinate the number of places. After all, there are priorities, and the follow-up cooperation arrangements will be in accordance with Follow the normal procedure."

Gu Qing said very modestly: "This is all because of our large investment in research and development, and the unremitting efforts of the research and development team, in exchange for the rapid progress of scientific research."

PS: Quotas are very precious. For example, if you sell a house in a community, you can’t buy a few big projects to pass the quota.
