Participating in the military's power armor project made Xia Ming passionate, and he was still thinking about which thigh to hug at night.

As many as 27 units are qualified to bid for the project, and it seems that the military is really rich, and it has adopted a strategy of catching everything in this project. These units include not only military research institutes, but also the Chinese Academy of Sciences and local scientific research institutes, as well as quite a few civilian companies. They all have many years of experience in the research of dynamic exoskeletons, and they have also launched validated models of powered exoskeletons.

Judging from the information obtained from a cursory search on the Internet, among these units, there are three of the most powerful.

One is the 2020 Institute, a veteran unit of the military, and although the second-generation power exoskeleton technology is not outstanding, it is the most complete system and the closest to practicality. The second is the Yanling Research Institute of the Chinese Academy of Sciences, which has been immersed in the power exoskeleton for more than ten years, and now has a third-generation power exoskeleton with many innovations in technology, which is the closest to the foreign level.

The third is Shanying Heavy Industries, which is a private company. In the past, it focused on heavy machinery and mechanical and electrical products, and in recent years, it has entered the high-tech field, from robots to power exoskeletons, and the power exoskeleton launched has advantages in transmission, and transmission is the most basic and core link of power exoskeleton and even power armor.

Xia Ming felt that with the technical level of the research institute and a little thought, he could come up with artificial intelligence that was enough to match the winners. So the question is not whether to hold the thighs, but who to choose as the thighs.

After deciding to contact these three units the next day, Xia Ming was ready to figure out the framework of this artificial intelligence first.

The artificial intelligence of the powered exoskeleton is a compensatory scheme with the aim of achieving a higher human-machine synchronization rate. The movement of the exoskeleton relies on human muscles and posture sensors to follow the movement of the human body, and there is a significant delay in response. So even the most advanced models such as the XOS-4 do not allow the occupants to change too quickly. Otherwise, the body will not be able to keep up with the movement of the human body, resulting in "man-machine disharmony", which will either deform the action or hurt people.

If the powered exoskeleton is only used to solve the weight-bearing problem, it makes little sense to pursue too high a synchronization rate. But no matter which country's army spends a lot of money on this, it is not for soldiers to be porters. The development of the power exoskeleton to the power armor is to build Iron Man. For example, the "Tactical Assault Light Armor Program" (TALOS) proposed by the United States a few years ago was upgraded to the "Advanced Power Armor Program" (APAS) last year, and the military hopes that soldiers can still be able to crawl and even be more flexible when wearing this thing.

So how do you solve the latency problem?

The delay is accumulated by the two links of sensing and transmission, in terms of sensing, if there is a brain-computer interface, it is simple, what people think, the machine can perceive, real-time synchronization. It's a pity that only Xia Ming and Xiao Huan have a brain-computer interface like QNI in the world. Ordinary people can only know what people are going to do after they produce signs of movement through changes in muscles and posture.

Even with a brain-computer interface, the machine cannot be synchronized with the human because the technology that drives the machine, whether hydraulic or electric, takes time to do the work. Unless you make the mental skeleton of science fiction, there will be a significant delay in the transmission.

Artificial intelligence makes its debut, just like Alpha Dog relies on learning to defeat the Go king, using artificial intelligence to learn human actions, and after summarizing massive sports data, it can make prejudgments and let the machine cooperate with people.

Assuming that the total delay of the machine is 0.5 seconds, after the soldier breaks through the door, the AI predicts whether the next action will continue to rush forward, dodge sideways, or backward based on the posture of the sole sensor and the built-in gyroscope, as well as the expansion of the muscles in the thighs and calves. Based on the prediction results, the machine is asked to act 0.3 seconds earlier (minus the sensing delay), and after 0.5 seconds, the man and the machine are basically synchronized in real time. As long as each major action change cycle is above the total delay, man and machine are one.

Of course, this also puts forward high requirements for the accuracy of artificial intelligence's prediction, if you rush into the door, facing the enemy's muzzle, you feel that lying down is the best choice, but this option does not have enough drills in advance, artificial intelligence does not know that there is such a response, judge that you are rushing forward, 0.5 seconds later, the machine takes you with a fork, and you can only cry.

From this point of view, artificial intelligence is not very reliable, so whether it is the United States or the domestic power armor project, it is only discussed in this regard, and it has not been deepened, this is Xia Ming's opportunity.

If for the sake of safety and reliability, if you do not pursue human-machine synchronization, artificial intelligence is still an irreplaceable part of power armor. Artificial intelligence is required to integrate the sensing system and judge the movement state of a person, and it is also necessary to coordinate various movement joints and adapt to various movement states. It's just that in these links, the so-called "artificial intelligence" is quite low-level.

In other words, Xia Ming needs to prepare two sets of artificial intelligence, one guaranteed and one advanced.

The context is clear, Xia Ming wants to follow the information on the Internet to build a prototype of the guaranteed artificial intelligence first.

As soon as I thought deeply, my brain throbbed, and R3AI also reported: "QNI information has caused irreversible changes at the physical level of the brain, and the original architecture is being reorganized." ”

Brain changes?

Xia Ming was startled at first, and then relieved, if it changes, it will change, as long as he is still himself.

But how long will the restructuring last? What are the implications?

"The change has been completed and has an impact on deep thinking, which will produce redundant warning signs until you adapt to the change."

Deep thinking is learning and thinking in the management mode, R3AI's answer made Xia Ming mixed with joy, happy that there was no big change, and worrying that this meant that before adapting, as long as he entered the state of deep thinking, it would be accompanied by indelible pain.

"Headache ......"

Xia Ming rubbed his head and made a pun.

The next day, Xia Ming found that there were still things that gave him a headache.

The three units have been contacted, with different attitudes, but the meaning is very consistent, they want to hug my thighs, no way!

In 2020, Xia Ming was not a bird at all, and the deputy director who answered the phone was very annoying, he should have received too many calls asking for cooperation, and Xia Ming also came to play the autumn breeze.

"We are a military-industrial unit! Ah, do you know what a military-industrial unit is? Picking up a piece of paper in our wastebasket and showing it to foreigners is the crime of espionage! Got it? How can you cooperate with your private units? Besides, the artificial intelligence of the powered exoskeleton, we are working together with the powered exoskeleton, why do we need to do one? Do you understand this? ”

The deputy director also criticized it unsatisfactorily: "Why is your research institute so unrigorous? Finding students to drill the door everywhere is the same as engaging in telemarketing, is it still a research institute? I'm going to talk to you guys! What a mess! ”

This must have been stuffy in the institute for too long, and he doesn't know what the outside world has become. As a citizen of the Republic, Xia Ming really couldn't afford to be angry. However, the taste of a hot face sticking to a cold ass is really unpleasant, and he is too lazy to play Shang Weidong's signboard to continue to fight.

The attitude of the Yanling Research Institute is very enthusiastic, and the chief designer personally went into battle to communicate with him, obviously having a deep understanding of artificial intelligence. But when it comes to cooperation, it's either a matter of branching out or shifting the subject. I was in a hurry, so I said that I could consider technology licensing and joint bidding, and I didn't even think about it.

Shanying Heavy Industries is more fun, Xia Ming first contacted their research institute directly, and the institute said that it is not independent, and the group has to make decisions on external matters. Well, Xia Ming looked for the group office again, but he stepped into the pit of corporate bureaucracy and didn't climb out all afternoon.

When they finally launched a vice president, the vice president's innocent words finally defeated him: "Power exoskeleton? Oops, wait until I ask what's going on. ”

Xia Ming only tasted the taste at this time, how could a powerful unit share this cake with outsiders? Other units don't pay much attention to the part of artificial intelligence, and on their own side, although they have the name of the Yanda Artificial Intelligence Research Institute, the essence is to strengthen the basic research of artificial intelligence.

It's pretty simple, why didn't you think of it yesterday?

Xia Ming fell into deep reflection, and concluded that the temptation of power armor is too great, and the sci-fi military technology Miyake will lose his IQ when he sees it......

Of course, he wouldn't just give up, or go to Shang Weidong to complain. Gritting his teeth, he found it in those small units, since even Lao Mei didn't play out of the way here, hugging the thighs of those large units in China, it was impossible to make anything good, it was better to become a thigh!

Just like distributing leaflets part-time before, Xia Ming's "street sweeping spirit" attacked, and he contacted one by one, but without accident, one by one was rejected.

Seeing that it was getting late and the 9-to-6 units were about to get off work, Xia Ming was like looking for a job, and he was mentally prepared to continue working hard tomorrow, and called a phone called "Yititang".

"Ouch, Yanda's research institute! How did you find me here? ”

The other party's somewhat surprised and somewhat flattered attitude made Xia Ming's heart perk, there was a chance!

The person who answered the phone was a woman, not very old and inaudible, probably in her twenties or thirties, who claimed to be the CEO of the company.

"Yi Liyan, another patient with difficulty in choosing a name", looking at the information on the list, it was indeed a woman, Xia Ming couldn't help complaining.

Although the discrimination occurred and he felt that a small company and a female boss were too incompatible with the painting style of the power armor, Xia Ming still firmly adhered to the principle of "doing his best in trouble" and transferred to QQ voice communication with Yi Liyan.

"I'll just accompany you, I'm not very interested in that matter, just have a good time."

Yi Liyan is very feminine, and she should have been raised by the boss.

She happily gave herself the bottom line, and in her early years she was involved in the HAL powered exoskeleton project at Cyberdyne, Tsukuba, Japan. After understanding the technology, he returned to China to start a business, and has opened up the situation in the medical market, and is one of the leaders of the domestic civilian exoskeleton industry. However, the domestic industry is already very small, and her company is not large-scale.

Yititang's powered exoskeleton is used to help the movement and rehabilitation of the disabled and paralyzed, and it is a few hats away from the military, so Yi Liyan is very entangled in the fact that she is being looked at by the military.

"The medical market is too shallow, and it's good to be able to change careers, but we have no experience in the military, and the military probably sees that our things are more mature in civilian use, so they pull us to make up the numbers. It's not bad to walk around, at least the reputation can increase a lot. But if you really go, you can't do the other line you originally wanted to switch, and you're in a dilemma these days, alas......"

Hearing her complain like this, Xia Ming asked casually: "Where else can I turn around?" ”

"Uh, that's the ...... Realistic dolls. ”

Yi Liyan said amazingly: "This market has great potential! I just asked you to do a market research, do you like a simulation doll that can walk, jump, and move in various postures? ”

Xia Ming, who was drinking coffee, snorted, and the screen was suddenly stained.

He struggled to make his voice sound calm and indifferent: "I have a girlfriend and don't need that, haha......"

God chatted with Xiao Huan and sent a grimace, and there were two words: "hypocrisy", this girl was eavesdropping again.

This is indeed hypocritical, he has a girlfriend, one is no longer there, and the other is still in pursuit. But he has a female friend who lives together, and although he often receives benefits, he is not a girlfriend. Therefore, he is really a potential consumer of artificial dolls.

Yi Liyan regretted: "It seems that you are quite normal, there are very few men like you now." ”

Since it's a minority, what's normal to call it!? Eldest sister, you just said that men are perverted......

Xia Ming changed the topic and said, "Why can't you do this?" ”

Yi Liyan sighed: "As long as I walk around under the eyes of the military, I will be marked by the army, how can I be asked to be a sex robot?" ”

Indeed, regardless of fame or technology, the military will not tolerate companies involved in the most advanced military projects in the country running to make artificial dolls.

"Isn't it okay to split into two companies?"

Xia Ming taught her the wisdom of splitting up the research institute.

Yi Liyan continued to sigh: "Without the Yititang brand, it is difficult to start from scratch." ”

Xia Ming thought about it and felt that this was really an opportunity: "Otherwise, your Yititang will not participate in the bidding, use your technology to build a new joint venture with us, and use the new company to bid." ”

Yi Liyan hesitated: "This path is good, but who can participate in the bidding is not something we can decide, right?" ”

"I'll solve this, let's meet first, and see if each other is not satisfied."

Xia Ming was ready for a business trip, and Yititang was in Haidu.

"It's okay, let's talk when we meet", Yi Liyan set a meeting time with Xia Ming very neatly.

Xiao Huan made a fuss on the god chat: "Big pervert! Big rascal! You're definitely going to buy an inflatable doll! ”

Xia Ming continued to have a headache: "It's a simulated doll...... No! I'm not going to buy any dolls! ”

"Then take me to Haidu! Let me supervise you! ”

Xiao Huan said solemnly, this is her true intention.
