Chapter 375 Your arrangement is a bit beyond my imagination! (5K votes requested, please follow up)
"How much time do we have to prepare?"
"At most three months, NASA has determined the time for the moon landing. We must come up with a feasible plan before then." Zheng Yang said with a hint of urgency in his voice.
"That's why we need your assistance."
Only then did Luo Yao realize why Zheng Yang was looking for him.
Logically speaking, he should not be approached for non-scientific research issues such as establishing a team.
"How can I help you?"
"Let's meet and talk."
"I think there are not many that China can handle."
Luo Yao quickly put on his lab coat and gloves, ready to start the inspection work.
“Only through meticulous modeling and accurate data processing can we ensure that the exoskeleton space suit’s walking and operation on the lunar surface can achieve the desired results.”
I don't know how many hours later, Luo Yao's eyes fell on a set of data.
Zheng Yang sighed and continued: "Actually, we do have a dedicated team responsible for developing space suits with exoskeletons. They have been working hard to overcome various technical problems, but the progress is not as smooth as expected."
"This bug caused the exoskeleton space suit to be unable to synchronize with the astronauts' movements during simulation tests, and sometimes even experienced lags and delays."
"Yuan Zheng is working and needs to wait for a while."
After Zheng Yang heard the noise, he asked Luo Yao to wait for him where he was, and then quickly walked towards the source of the sound.
Zheng Yang did not agree: "That won't work. You have a heavy workload in a day and you need to supplement your nutrition."
[Academician Luo, this is unscientific (T ^ T)]
He spoke slowly: "Zheng Yang, space suits with exoskeletons are indeed a cutting-edge and promising research direction."
Luo Yao was depressed.
Luo Yao heard what the other party meant.
Luo Yao asked Zheng Yang to wait for a moment. He sent the preparatory technical information of the muon collider to the project leader, and asked the other party to split the document and distribute it, so that each research group could learn first, and then follow Zheng Yang went to the laboratory.
I thought that he loved to eat the big pot of rice in the cafeteria, so why not let him eat it.
By the time Zheng Yang saw Luo Yao, it was already the next day.
"What can make little moss fail?"
Luo Yao nodded, he understood what Xiao Moss meant.
"However, Xiao Moss has not found any problems, so can this model alone be enough?"
At this point, Lao Huang's eyes were already wet, but he held back the tears and continued: "They are all people I brought out with my own hands. Seeing them like this, my heart really feels like a knife."
He further explained: “In addition, space suits with exoskeletons may also be equipped with advanced sensors and control systems, allowing astronauts to perceive and operate the space environment more intuitively, improving mission execution efficiency and success rate. "
He smiled slightly, which comforted Little Moss, and then began an in-depth inspection of the control system of the exoskeleton space suit.
Lao Huang was about to agree when his eyes suddenly locked on Luo Yao who was coming to see the situation.
"We have found a direction for materials, but structural design is a big problem." He continued, "The exoskeleton needs to be perfectly integrated with the astronaut's body, not only to ensure flexibility, but also to provide sufficient support and protection."
"Zheng Yuan, don't bother me. I'll eat whatever I have."
Lao Huang's face became more solemn. He lowered his head and thought for a moment, then raised his head: "Academician Luo, Yuan Zheng, I understand your concerns."
"This requires us to consider many aspects of the human body's kinematics, mechanics, and physiology when designing, which is extremely difficult."
A top scientist pointed out their problems in public, which simply made them face the gap between them and Luo Yao.
"But I looked at the data from the simulation test and found that the transmission and distribution of this torque did not achieve the expected results."
Just when Zheng Yang was about to step forward and continue to remind Luo Yao, Luo Yao finally stopped writing.
No one else showed any particular surprise on their faces.
"Gong Luo, I want to confirm something above. If we are going to conduct space operations, should we study space suits with exoskeletons?"
"Yuan Zheng, this matter is also related to Academician Luo. Can we talk together?" Lao Huang said excitedly.
Luo Yao still ignored him.
That's too! Disaster! Suffer it!
Luo Yao didn't care about other people at all, he was completely speechless now.
"We tried to let Moss do assisted design optimization, but in the end she also failed."
"Every step from material selection, structural design to system integration is not easy."
Zheng Yang couldn't help but look sad when he heard this. He knew that such a blow would be unbearable for anyone.
If you get this kind of modeling wrong, what does it matter?
“After in-depth analysis, we can find that the main reason for the difference between theoretical calculations and simulation results is the error in the modeling process. When building a joint-assisted exoskeleton robot model, there are certain differences in the center of gravity position, moment of inertia, assembly, etc. of each component. error."
"As long as there are no problems with the brain nerves, recovery is fairly simple."
Everyone nodded quickly.
"No, this is not an ordinary calculation, he is doing dynamic modeling!" A senior researcher suddenly realized. He pointed to the content on the whiteboard and explained, "Gong Luo is based on the data of the exoskeleton space suit walking on the lunar surface. , establish a dynamic model of lunar surface walking. Through this model, we can more accurately analyze the movement characteristics of the exoskeleton space suit on the lunar surface, thereby finding out the reasons for the failure of the simulation test. "
“When transferring samples while standing, the required torque ranges of the upper limb joints are [9.32, 12.42] Nm and [4.53] respectively. This data shows that the upper limb joints of the exoskeleton space suit need to provide sufficient torque to support when performing delicate operations. Astronaut’s movements.”
The three of them came to Zheng Yang's office. Lao Huang just waited for Zheng Yang and Luo Yao to sit down before speaking.
After hearing this, Zheng Yang couldn't help but look serious. He raised his hand to the side and said, "Let's go in first and then talk."
"Zheng Yuan, I have something to ask of you today."
The faces of the people standing nearby gradually became confused.
The researchers are about to cry.
“The benefits are clear, but there are also many constraints.”
“Although these errors may seem small, they will be amplified in complex dynamic calculations, resulting in significant differences between simulation results and theoretical calculations.
"This space suit can provide more comprehensive and effective protection in the face of possible space debris, radiation or other potential threats."
He completely regarded the people around him as nothing.
Luo Yao sometimes stopped in front of the whiteboard, and sometimes his calculations made Zheng Yang a little worried.
He didn't hear any of the other people's discussions.
"Old Huang, why are you here?" Zheng Yang looked at the dark man in military uniform in front of him, with surprise on his face.
[Academician Luo, if you believe me, it’s really not my problem. 】
"This is critical as we respond to possible emergencies or conduct complex space missions."
"Also, you are stupid, don't blame the artificial intelligence."
Luo Yao followed Zheng Yang to the laboratory. As soon as he entered the door, he saw a group of scientific researchers busy surrounding a large equipment.
"But I have something urgent and I need to see him!"
"Everyone has suffered varying degrees of injuries. Some have lost their arms, some have had their leg bones amputated, and some... they cannot take care of themselves now."
He held the paint pen, pointed at the model on the whiteboard, and said: "According to dynamic calculations, when walking on the moon, the required torque ranges of the lower limb joints are [-3.7 and [-6.05, 13.1] Nm respectively."
"This time, I am doing it for the 25 people in our group."
This device is the core part of the exoskeleton space suit they are developing.
“Similarly, when squatting and standing up, the required torque range of the lower limb joints has also been accurately calculated, which are [1.31, 2.29] Nm and [1.29, 12.01] Nm respectively. This data reflects the astronaut’s ability to squat and stand up. The exoskeleton space suit should provide a range of supporting moments during movement. However, in actual simulations, this range of moments was not accurately reflected. "
"Who says we have to abandon them?"
"To put it simply, this space suit can not only significantly enhance astronauts' ability to move in space, especially in microgravity environments, it can effectively help astronauts perform faster and more precise operations."
"No, you wait until I finish speaking."
He knew very well what Little Moss was capable of. Since she said there was no problem with the code, it was likely that the problem lay somewhere else.
"Well, these people have not achieved any results so far. This is abnormal. It shows that their talents in this field only end here."
Luo Yao walked to the quantum computer on the side. After Xiao Moss detected Luo Yao's approach through the camera, her words were displayed directly on the screen.
The kinetic energy of the thigh rod and the potential energy of the thigh rod.
"Also, system integration is even more difficult." Zheng Yang frowned, "The exoskeleton space suit not only needs to match the physiological functions of the astronauts, but also needs to be seamlessly connected with various space equipment and systems. , which requires us to carry out deep integration and optimization at multiple levels such as hardware, software and algorithms, and a slight mistake may cause the entire system to collapse. "
The researchers were silent, thinking that they must have heard this wrong!
How could the famous Academician Luo say such immodest words?
"Okay, the model is set up for you. You can let the little moss sweep it in later. She should have no problem using my set."
When the researchers heard this, their faces began to turn red.
Xiao Qi retorted at this time: "Have you forgotten that no matter how strong Little Moss is, it was all developed and designed by Academician Luo?"
"Academician Luo! It's so great to meet you this time!"
"This means that when the exoskeleton spacesuit walks on the lunar surface, its lower limb joints need to provide and withstand specific moments to ensure the stability and comfort of astronauts walking. However, the simulation results are obviously different from the theoretical calculations. .
"Little Moss, look at the algorithm call here, is there something wrong?" Luo Yao pointed at a certain piece of code on the screen and said.
He looked at his watch. It had been three hours. If Luo Yao continued like this, could his body bear it?
He had to say: "Gong Luo, please take a rest first, let's start again later, shall we?"
Zheng Yang brought him to the team responsible for software development, pointed to a researcher and said: "This is Xiao Qi, the main developer of the exoskeleton space suit control system. He had previously tried to use small moss for auxiliary design optimization, but failed ”
Luo Yao silently walked to the whiteboard aside and started writing.
[There is nothing wrong with their code, but I don’t know why, but there are always problems during simulation tests. 】
They looked at the complex formulas and graphics written by Luo Yao on the whiteboard and found it difficult to understand the meaning behind them.
“What you have to do now is to re-examine and optimize the modeling process, especially the processing of the physical properties and motion data of each component.”
They only have one feeling now.
Luo Yao:? ? ?
"You want me to take the lead in building it?"
If even Luo Yao believes that it is necessary to establish a dynamic model to further analyze the problem, then this must be the key to solving the problem.
"Because the things you study are going to go into space."
"What is Gong Luo doing?"
"Can Luo Gong make it?"
"But after your people recover, what do you plan to do?"
When Luo Yao was calculating, it could be said that he was quite focused.
After Zheng Yang heard this, he frowned and said, "People who install mechanical equipment are prone to accidents when they are with ordinary people."
"I'm just thinking, rather than having them go back to their original team, we might as well consider forming a new team just made up of these guys who have installed the machinery."
After Luo Yao finished handling the affairs of the institute, the director looked at the eliminated list in his hand and said with some hesitation: "Have all the people like Academician Luo been screened out?"
"We tried to use the little moss to assist in the inspection, but the little moss also failed."
Luo Yao quickly scanned the code. His eyes were sharp and focused, and he seemed to be able to discern the logic behind each line of code. Suddenly, his brows furrowed, as if he had discovered something abnormal.
"Yes, Academician Luo's modeling ability is top-notch. Since he started modeling, he must have discovered problems that we didn't notice." Someone agreed.
They did ignore this point. Although Little Moss is a powerful artificial intelligence, in the final analysis, its core algorithms and logic were designed and perfected by Academician Luo Yao.
After Luo Yao finished explaining, he originally wanted to continue looking at the system, but he found that he was hungry.
Lao Huang was stunned and said hesitantly: "Return to the original team?"
He continued his in-depth inspection, and no one else dared to disturb him or stand aside and did not dare to speak.
Director:……
"We don't know about this either. If you have time, Mr. Luo, you can come with me to have a look."
Lao Huang took a deep breath, with an expression of grief and perseverance on his face, and continued: "Academician Luo, Yuan Zheng, just last year, when our group was conducting a blasting removal, an explosion suddenly occurred. "
Zheng Yang didn't know why, so he thought about it and agreed.
Zheng Yang learned that Luo Yao was hungry and quickly called the canteen to prepare fresh meals.
Xiao Qi said even more sadly: "Thank you, Luo Gong, for your guidance. If it weren't for you, it would have been a long time before we discovered the problem."
"I want to see Zheng Yuan."
Xiao Qi raised his head in frustration and introduced the problem they encountered to Luo Yao: "Gong Luo, when we were writing the control system code, we encountered a bug that was difficult to solve."
Xiao Qi's rebuttal immediately silenced the discussion around him, and everyone's faces showed that this was indeed the case.
Compared with a genius like Luo Yao, who dares to say that he is talented?
After the depressed director sent Luo Yao away, he held a series of lectures called "Scientific Research Capability Improvement Lecture Series" in the institute, which made people in the institute complain again and again.
"It looks like it's doing some complex calculations," another engineer speculated.
[Academician Luo, you are right. There is indeed a problem with this algorithm call, but it is not the reason for the failure of the simulation test. I have checked it many times and there is no problem with the algorithm itself. 】
Luo Yao became interested.
This is to say that the little moss has no effect either.
Only then did they realize that Luo Yao seemed to be looking for a place for Xiao Moss!
After hearing Zheng Yang's question, Luo Yao had a flash of thought in his eyes.
"The physical structure and abilities of people who have installed mechanical equipment are indeed different from ordinary people. Returning to the original team may bring risks. However, they were once excellent warriors and they had deep loyalty and loyalty to the country and people. Love, we cannot abandon them just because they have suffered misfortune.”
Lao Huang continued: "Academician Luo, I know that you are very skilled in rehabilitation medicine. I heard that Wang Ying of the Space Flight Brigade was cured by you using brain-computer technology. I would like to ask you whether this method can help. They regain some basic living abilities? I know it is difficult, but as long as there is a glimmer of hope, I don’t want to give up.”
The two people walked out of the laboratory and heard a noise outside.
"The driving function established using processed motion data also brings errors. Although the data has been carefully processed, there are still some noise and outliers, which will affect the accuracy of the driving function."
Luo Yao paused and continued: "Moreover, exoskeleton space suits can also provide an additional layer of protection to enhance astronauts' survivability in space."
Luo Yao said seriously: "It's also possible that you can't find the problem. This problem involves mathematics, physics, dynamics and other fields, and you can't solve it."
He understands that spacesuits with exoskeletons do have a range of potential advantages in space combat.
"Old Huang, please sit down and speak slowly." Zheng Yang was worried that the other party would become excited again, so he said quickly.
They should actually be happy that someone of Luo Yao's level is pointing out problems to them, but now they just feel embarrassed.
When Zheng Yang heard this, his expression changed, but Luo Yao asked curiously: "What happened to the 25 people in your group?"
"I know that this accident has dealt a huge blow to them and their future has become dark as a result."
"Yuan Zheng, and Academician Luo, I have something to ask of you."
"The mission location is space."
Zheng Yang:? ? ?
Lao Huang:? ? ?
"Gong Luo, your arrangement is a bit beyond my imagination." Lao Huang is an honest man and will not lie at all.
How can their remnant soldiers go to space?
