After some arguments, Yang Bufan was able to stay in the laboratory and observe the installation process of this intelligent prosthetic throughout the process.

Installation is not a difficult thing, this is a lifelong study of Academician Chen, the treatment and design of the cavity are very advanced, Zhao Ying may not feel much foreign body sensation after installation, plus this prosthesis is made of ultra-light alloy metal, which ensures the strength and greatly reduces the weight, which is more suitable for women.

The controller is a hat that sticks to the scalp, and before that, Zhao Ying was shaved with his eyes closed, revealing his smooth scalp.

Although everyone was very sorry, in order to get the best effect, even Zhao Ying herself couldn't bear to cut her love.

Wearing a signal receiver specially designed to receive brain waves, the EEG signal is received from the scalp, and then the computer control program receives it and is translated by the algorithm into a specific signal that can be realized, and then the prosthesis can complete the recognition.

The system itself was manufactured, which was a miracle, but now it has not reached the point of complete success, because it also takes a process for Zhao Ying to learn how to train how to imagine in his mind and make the prosthetic complete the action.

Academician Chen no longer has the stubborn behavior of the past today, wearing a white coat and looking serious, this time he really looks like an out-and-out researcher.

The first step they had to do was to use the socket to install a prosthetic leg, and although this was what these researchers were best at, Academician Chen still took it personally.

While installing this intelligent prosthetic, Academician Chen chatted casually.

"There are actually two kinds of control methods for this intelligent prosthetic, and now the more high-end ones in the world are myoelectric prostheses, and they are also relatively mature technologies, that is, to control the prosthetics through the changes in the patient's muscles, but there are two problems, the first is that the patient must have a part of the muscles, Zhao Ying does not have the whole arm, it will be very difficult to install, and it is not easy to control the installation. ”

What Academician Chen said seemed to be small talk, and it seemed that he was giving a lecture to Dr. Lu, but Yang Bufan always felt that this old man was testing himself by speaking in such detail today.

But it doesn't matter, Yang Bufan doesn't mind exposing his technical level, as for the real reason, you can guess as much as you want.

Thinking of this, Yang Bufan even had time to talk: "Old Chen, I understand, if it is a half-amputated arm, it may be better to install a myoelectric prosthesis, right?"

Academician Chen operated the socket in his hand, constantly adjusted according to Zhao Ying's physical condition, and replied casually: "So this is a shortcoming of myoelectronics, you must have muscles, which limits the use of myoelectric control prostheses." ”

Yang Bufan opened his mind at this time and said: "Actually, it's not impossible, you can install myoelectric energy on your shoulders and chest, and it's the same to use the muscles here to control it, but you need to train!"

Hearing this, Zhao Ying's face turned red instantly, and she didn't know what she was thinking.

Lu Jiaying also glared at Yang Bufan fiercely, and said in her heart How can this Mr. Yang be open-mouthed, how can a girl install a myography control system there, isn't this a joke, look at Zhao Ying's shame!

Academician Chen shook his head, obviously not caring about what Yang Bufan said just now.

"No, it's not so simple, even if it can be installed on the main torso of the body, but the control effect will be greatly reduced, and it also involves the second drawback, according to the weight of the electromyography control system is too heavy, the weight of dozens of pounds is impossible for a strong man to use for a long time, and it is even more difficult for women to carry it. We make prosthetics to allow people with disabilities to gain convenience and the ability to live independently, in the final analysis, to let them get the hope and dignity of life, what else to play with the weight of dozens of pounds of myoelectric prosthetics, so myoelectric prosthetics have a bottleneck in development. ”

Yang Bufan felt fascinated by what he heard, but he didn't expect that the medical equipment industry also has so many twists and turns, which is not simpler than the automotive industry.

And after listening to Academician Chen's words, Yang Bufan had a new thinking about the value of EEG intelligent prosthetics.

"Old Chen, then from the cost point of view, which one is lower?"

Academician Chen pouted, his eyes were motionless, he had already installed the prosthetic leg for Zhao Ying, and only after completing all this did he say: "It's all expensive! The cost of materials, process processing, and installation are all very much, but the most expensive is the chip, and a lot of the funds used up recently have been used to buy chips." ”

Yang Bufan was immediately thoughtful when he heard this, but the chip thing is a bit too far, and Huawei's bullish companies have been made very uncomfortable, and the National Academy of Sciences has even listed technologies such as chips and lithography machines as key research and development projects, which shows that this thing is not easy to research.

But the lithography machine ...... I think I can really redeem it!

Yang Bufan suddenly had a feeling of enlightenment, and his heart was also excited, and he faintly had a lot of immature thoughts.

At this time, everyone stopped chatting, and they all looked at Zhao Ying and asked her how she felt.

Zhao Ying was very excited at this time, seeing that she finally had her right arm and right hand, her eyes were foggy.

But no matter how hard she tried to control the new arm, it didn't move.

When Yang Bufan saw Zhao Ying's movements, he knew that she hadn't understood the principle of all this, and thought that she just needed to move her muscles.

"Zhao Ying, don't worry, don't be so nervous about your muscles, you see that the green tendons on your neck are coming out!"

Zhao Ying sighed and quickly relaxed.

Academician Chen checked the installation again, and finally nodded after finding that there was no problem at all and the signal receiver and transmitter were connected normally.

"Yang Bufan is right, don't worry, how to use brain waves to control prosthetics also needs to learn and exercise, let's not be in a hurry, let's start with the simplest way to raise your arm. Come, Zhao Ying, you need to imagine in your mind that this arm is yours now, and then you want to raise your arm, come, don't worry, think slowly. ”

Zhao Ying took a deep breath, knowing that this matter was not in a hurry, and after a few deep breaths, her emotions finally stabilized, and then kept repeating in her mind to raise her arm.

A second passed.

Half a minute passed.

A minute passed.

Only the prosthetic arm remains unmoving.

Seeing this situation, Yang Bufan was a little anxious.

According to the design of EEG prostheses, manipulating the prosthetic is a matter of thought, although at first it is not as good as controlling your real arm, but the slow movement should be absolutely possible.

But now after Zhao Ying has installed the prosthetic, the prosthetic has not moved at all.

Could it be that there is a problem with the design or manufacturing process of the prosthesis, or is there a problem with the procedure?

Prosthetic design or manufacturing, this is a hardware problem, and now it's too late to change it, so you have to start over.

But if it's a program problem, or an algorithm problem, then Yang Bufan feels that he can still try to check it.

After all, in this room, when it comes to computer and software technology, Yang Bufan is sure that he is the strongest.

In the past, the algorithms and procedures of the intelligent prosthetic were all made by these researchers, and the specific situation is still up for debate.

Yang Bufan felt that it was really necessary for him to look at the internal procedures of the prosthetic.

The trial is still ongoing.

Zhao Ying's face was a little sweaty.

Even Dr. Lu Jiaying's face was not normal.

The faces of the other researchers turned even more disgraced, and they even felt that the experiment was already a possibility of failure.

Only Academician Chen has been not arrogant or impatient, slowly communicating with Zhao Ying, and then asking her to constantly adjust her emotions.

"Concentrate on it, don't think about it, and think only one thing as much as you can, and that's to raise your arm! Don't think that the arm is not your own, just assume that the arm is your own!"

Zhao Ying nodded and closed his eyes directly.

At this moment, everyone stopped talking, and the whole laboratory fell silent, except for some instruments that made regular dripping sounds.

Time passed minute by minute, and just when everyone was about to give up, the fingers of the mechanical arm actually moved!

It's not the arms that move, but the fingers!

Academician Chen's eyes lit up at that time, because the most difficult thing to control in an intelligent prosthetic is not the arm, but the most flexible fingers!

Now I can move my fingers, which means that there is no problem with this test prosthesis.

The hardware is fine, it's the software and the interaction algorithms!

As long as the hardware is okay, other problems can be improved by constantly collecting brain waves and doing calculations!

"It's moving, it's moving!"

Just when everyone was almost holding their breath, Yang Bufan's excited shout suddenly came.

Then the fingers didn't move at that time.

At this moment, Academician Chen, Lu Jiaying and the other researchers glared at Yang Bufan fiercely as if their biological parents had been killed.

How does this product know to make trouble!

But when Zhao Ying opened her eyes at this time, she was surprised.

"Did you really move just now?"

Yang Bufan nodded categorically and said: "It's moving! It's amazing! I think it will take at least ten days and half a month of training to control a prosthetic leg with brain waves, but I didn't expect you to do it so quickly!"

Zhao Ying's eyes sparkled: "It's good to be able to move, it's good to be able to move!"

Several other people were completely convinced by Yang Bufan's flickering technique, EEG prosthetics have never been truly realized in the world, it was a concept in the past, how long does it take for patients to learn and train well, and they have no experience at all, so Mr. Yang opened his mouth to come.

However, this also has advantages, that is, Zhao Ying can't control it for three or five days, and it is estimated that she will not be too anxious.

After all, Mr. Yang said that it usually takes half a month of training.

Academician Chen also understood this problem, knowing that Zhao Ying needed to strengthen the control of EEG, and the algorithm and program also needed to be matched, so these should not be in a hurry.

So Academician Chen also said with a smile: "Mr. Yang is really professional, what he said is very right! Zhao Ying, you girl, you can control it in such a short time, it is already very strong! This shows that your brain waves are more active, and your spirit is easy to concentrate, come on, don't worry!"

Hearing what the academicians said, Zhao Ying was of course convinced, and she had confidence, and she started to try slowly again.

This time, the progress directly surprised everyone.

It only took less than five minutes for Zhao Ying's smart arm to complete the action of lifting up.

It's just that after lifting it, the arm can't be put down, and it has been hovering in mid-air.

Even so, everyone was very excited, and the whole lab applauded.

It's just an action, but everyone understands how big it is!

This shows that this research is reliable and successful!

Whether it's hardware, software and algorithms, it's all a success!

All that's left is to slowly grind in and improve until it's getting more and more perfect!

And what Zhao Ying has to do is to continue to cooperate and deepen his brainwave habits and stability, and when he can do it like his fingers, it is the moment to declare complete success.

As Zhao Ying's confidence grew stronger and stronger, the raised arm was lowered again, and only a few minutes passed.

After another minute, Zhao Ying could already complete the movement of raising and lowering her arms relatively smoothly.

Then Zhao Ying began to train arm bending movements under the guidance of Academician Chen.

The difficulty coefficient of this action is definitely much more difficult than the simple action of lifting and putting down, everyone thinks that Zhao Ying can complete it today.

Unexpectedly, only half an hour has passed, and this action has been completed!

At this time, everyone still wanted to continue research, but Academician Chen found that Zhao Ying was a little overdrawn.

After all, she needs a high degree of concentration in the process of practicing, which causes Zhao Ying to get tired easily, and continuing to practice in this state is also half the effort.

Thinking of this, Academician Chen waved his hand: "Let's get here first in the morning, let's have lunch, then Zhao Ying listens to music and takes a nap, and we will practice for a while in the afternoon! Don't worry, take your time, step by step!"

Zhao Ying shook his head at this time: "Old Chen, I don't think I'm tired, I can practice for a while!"

Obviously, Zhao Ying was very excited at this time, and the satisfaction of having her arms made her all kinds of hormones soar, where could she still feel tired.

Yang Bufan also saw this, and coughed directly: "It's time to eat soon, listen to me, let's eat." Zhao Ying, what do you want to eat, I'll let the canteen send it over. ”

Zhao Ying saw that Mr. Yang said this, and he no longer insisted, but said with a smile: "Pig's feet rice, what to eat and what to make up!"

Zhao Ying is really a talk show actor, and a simple sentence made all the researchers who had gone through a morning of intense work laugh.

Academician Chen was also fascinated when he heard this: "Then I'll also go eat pig's feet rice, haha!"

Yang Bufan also coaxed: "Go and go together!" In the future, I will ask the chef to prepare more pig's feet every day, but recently the pig's feet are not enough, and I want to invest in building a pig breeding base. ”

As soon as such an unreliable idea came out, everyone was helpless.

But I didn't expect Academician Chen to agree very seriously: "I think it is possible! Not only can you build a pig breeding base, but you can also grow vegetables and farmland, all the ingredients are original, then the Xingbang canteen will be completely complete." ”

The speaker has no intention, but the listener has the intention.

Yang Bufan directly opened the memo in the factory dog system and silently wrote down the idea.
