Great Country Academician

If we say that the bionic mechanical legs transplanted on the disabled have shown to some extent that this device not only replaces the daily functions of the lower limbs, but also has powerful strength and explosive properties.

The carrying capacity of a single leg exceeds 500 kilograms. This is still due to the limitations of the material itself. If the material is replaced with a better-performing material, the explosive power it can provide may be even more terrifying.

But even so, in terms of flexibility displayed by bionic robotic arms, robotic legs still fall behind.

Even Xu Chuan was a little surprised by what his sister had done.

Even to a certain extent, this bionic robotic arm can perform more functions than normal human arms and fingers.

Just like human fingers and joints, although they can bend and twist, they cannot rotate 360 ​​degrees, bend and grasp in the opposite direction.

But this bionic robotic arm can do it. Each of its fingers is independent and can transmit nerve sensing signals independently.

The joints are made of micro servo motors, satellite sensors, pressure sensors and other refined components, making it easy to grab and pinch objects.

To take the simplest example, a normal person cannot bend his palm 180 degrees so that the palm or the back of the hand and the forearm fit together.

But this bionic robotic arm can.

Although the clinical experimenter who controlled it found it awkward to use, it was far less smooth than normal movements such as grabbing, making a fist, and pinching and releasing.

But it really did it, right under the noses of Xu Chuan and everyone.

Looking at this bionic robotic arm that was so dexterous that it was even far superior to a normal human arm, Xu Chuan had a look of deep interest on his face.

After the two clinical trial patients completed the relevant examination procedures, he looked at Xu Xiao and asked with an interested tone.

"Xiaoxiao, can this bionic robotic arm be made into an exoskeleton? Or a type of independent robot."

Xu Xiao nodded and replied: "It's okay, but the various servo motors, satellite sensors, pressure sensors and other components used in the bionic robotic arm are relatively sophisticated."

"And currently we do not write relevant robot AI programs like other robot companies. All control systems are mobilized based on brain-computer interface chips and related brain nerve signal databases."

"Brother, if you want to use it as a robot alone, control will be a huge problem."

"At least so far we have not studied experiments that directly control an entire bionic machine through a brain-computer interface chip."

"For people with disabilities like this, who are missing a leg or an arm, the nerve signals transmitted from the brain can be directly transmitted to the bionic arm without conflict or duplication."

"If it is controlled by a separate robot, I don't know what will happen yet. After all, the clinical trial has just begun."

"But this is also one of our next research directions."

After a pause, Xu Xiao pursed his lips and continued: "But these are all minor problems, brother. The current problem is that there are errors in nerve signal transmission. If this is not solved, this technology will not be usable at all."

Xu Chuan nodded and said with a smile: "Don't be too anxious. Being able to do this is already quite outstanding."

"As for the problem of nerve signal transmission errors, please sort out the relevant experimental data, including some data when the two mathematical models are running, and send them to my email in full, and I will find time to take a look at them."

Hearing this, the sadness on Xu Xiao's face immediately dissipated, and she jumped over with a smile on her face and said coquettishly: "Brother is the best!"

In the laboratory, Xu Chuan smiled and was about to speak when he suddenly remembered something. He looked at Zheng Hai and said curiously: "By the way, Zheng Hai, what were you planning to say before?"

Zheng Hai smiled sheepishly and said, "Actually, it's nothing. I mainly want to ask if the equipment Xiaoxiao is researching can be used for military purposes."

"For example, exoskeleton combat equipment, individual robots, mobile exoskeletons and the like."

"But Xiaoxiao just said that this kind of bionic mechanical device is currently mainly controlled by neural signals. Whether it can be controlled simultaneously is still unknown."

Xu Xiao smiled and said: "Brother Zheng, I have actually thought about this problem for a long time. Applying this kind of bionic robotic arm to military equipment in a systematic way is not completely different."

"Huh? What should I say?" Zheng Hai asked curiously.

Xu Xiao thought for a while and said: "Theoretically, if you add a neural signal blocking device through a neural signal synchronizer, you can remotely control the bionic machine."

Hearing the two academic terms, Zheng Hai looked over at a loss, not quite understanding what Xu Xiao meant.

Xu Xiao thought for a while and explained: "To put it simply, it uses a brain-computer interface chip to temporarily intercept all brain activity signals and prevent them from flowing to the body, but transfer them to the bionic robot."

"In this way, when the human body does not need to move, the robot can be remotely controlled to carry out activities while the human body does not need to move."

Hearing this, Zheng Hai quickly asked: "Can it be done?"

Xu Xiao shrugged and said: "Theoretically, it is possible, but the brain neural interface + bionic robotic arm we are currently researching is still far away."

"If this technology is to be realized, there are two core issues. The first is the feedback of external signals, which can be transmitted back to the brain in real time, clearly and stably, and the brain needs to analyze and process them while receiving them."

"For example, vision, hearing, touch, smell and other senses."

"The second point is that if this technology encounters electromagnetic attacks, it is very likely to be directly scrapped."

"You know, the main way to transmit various signals at present is electromagnetic waves. And electromagnetic attacks are fatal to the signal transmission of electromagnetic waves."

"So I don't really recommend this technology to be used in the military."

"On the one hand, it is difficult to achieve, and on the other hand, it is easy to be attacked."

After a pause, Xu Xiao looked over and said with a smile: "But there is another way to use exoskeletons in the military, which is simpler and easier to achieve."

"What method?" Zheng Hai asked quickly.

Xu Xiao: "Synchronous exoskeleton!"

"Synchronous?"

"Yes! Synchronous!"

"To put it simply, it is to synchronize the neural signals of limb activities to the bionic exoskeleton device through the brain-computer interface chip on the traditional exoskeleton wearable equipment, replacing the original intelligent sensing and AI control system."

"In this way, it will be more flexible than the traditional exoskeleton device, more adaptable to human activities, and more adaptable to complex military operations."

"Even!"

Speaking of this, Xu Xiao was already a little excited, his tone was several degrees higher, waving his arms and saying passionately: "We can even wrap the whole person with a complete exoskeleton device."

"In this way, the human body is inside, and the exoskeleton covers the whole body. If you add some adaptive buffering materials inside the exoskeleton, you can better deal with the killing of weapons."

"Of course, this kind of exoskeleton device is no longer an exoskeleton device strictly speaking. It should be called a single-soldier mecha!"

Hearing Xu Xiao's thoughts and looking at her excitement, Xu Chuan couldn't help shaking his head.

This girl has always liked whimsical and adventurous things since she was a child.

If she really makes a single-soldier mecha, her personal safety in the future will probably be a big problem.

To be honest, from the perspective of a brother, he doesn't really want Xu Xiao to study these things.

Because after touching them, he will definitely be targeted by intelligence organizations such as the CIA and hostile countries.

Even if the country can protect Xu Xiao like it protects him.

But for any matter, it's better to be safe than sorry.

Compared with these research and development, he cares more about Xu Xiao's stable life.

Forget it, let her do whatever she wants. Anyway, 50% of the shares of Starlight Virtual Technology Company are in his name. Even if the research results are really developed, they can be attributed to him.

Anyway, he doesn't lack this result. Too many lice don't itch, too many debts don't worry, he has been on the CIA's focus list for a long time.

Even over there, he may be the focus of attention, and the other party has been eager to kill him.

On the side, hearing Xu Xiao's explanation, Zheng Hai's eyes also brightened.

He looked at Xu Xiao and said, "Do you need experimental personnel? I can help contact the military and arrange a few people to cooperate with your follow-up research?"

Before Xu Xiao spoke, Xu Chuan smiled and interrupted, "Let me handle this matter. Simply arranging a few people to cooperate with the research is not very meaningful."

"Brother?" Xu Xiao looked over in confusion.

Xu Chuan smiled and said, "In addition to the personnel issue, don't underestimate the research and development capabilities of the army."

"Whether it is the research and development capabilities of the equipment department of the army or the scientific researchers of the Seventh National Defense University, they can speed up your progress in these research."

After saying that, he silently added in his heart.

"In addition to research progress, these research institutions and universities can also share some fame and external pressure, at least reducing the attention of foreign intelligence agencies to you, a silly girl."

"Rash, alas~"

Sighing, Xu Chuan shook his head and put his mind back.

Sometimes, being famous is really not a good thing. I just hope he can protect it as much as possible.

At the foot of Zijin Mountain, in the villa complex.

After taking a shower and wiping off the water droplets on his hair, Xu Chuan walked into the study and turned on the computer.

After inserting the USB flash drive in his hand into the computer, he shouted.

"Xiao Ling, help me import the data in this USB flash drive into the SAS database integration platform, MathCAD, MATLAB and other software."

In the study, a light voice soon sounded.

"Received, Master!"

The data files in the USB flash drive are some clinical experimental data of Xu Xiao's brain-computer interface chip and bionic robotic arm.

As for the SAS database integration platform, MathCAD, MATLAB and other software, they are several statistical analysis software widely used in data analysis, data mining, business intelligence and scientific research.

To solve the problems encountered by brain-computer interface chips and bionic robotic arms during use, the first thing to do is to find the problem.

Of course, this problem is not what Xu Xiao said that the signal transmitted from the brain-computer interface chip to the bionic robotic arm will have an abnormal problem.

It is a situation that is actually reflected in these experimental data.

As for the direction of research, it is naturally from the mathematical model of brain nerve multi-electrode array reset established by Xu Xiao and Liu Jiaxin, and the conversion of simulated neural signals and electrical signals of quantum theory that he had previously helped to study.

According to Xu Xiao, the problem is very likely to occur in the conversion of brain nerve signals by these two mathematical models.

But for Xu Chuan, from a feeling point of view, he actually doesn't think the problem will appear here.

It's nothing, just confidence in his research results.

It's not that he hasn't seen the mathematical model of brain nerve multi-electrode array reset. When he helped Xu Xiao solve the problem of converting simulated neural signals and electrical signals in quantum theory, he checked it in detail.

And with his personality, when solving this problem, it is impossible not to consider the conversion problem between the two.

But having an entry point is better than having no entry point.

First eliminate the problem that the conversion conflict between the two may cause abnormal neural signal data, and then look for other possible problems. This is the fastest way to deal with this application problem.

"Master, all the data has been imported."

In the study, Xiao Ling's voice sounded, and Xu Chuan casually praised: "Awesome, so efficient."

"Thank you for the compliment, Xiao Ling will continue to work hard (ω)!"

Xu Chuan smiled, dragged the mouse, opened the SAS database integration platform first, and his eyes fell on the data provided by Xu Xiao.

Compared with the difficult problems in applied mathematics that he had solved in the past, the problem of conflict between brain-computer interface chips and neural signal conversion is actually similar.

Although the fields of biology and physical chemistry are almost unrelated, for mathematics, the core is not what is presented on the surface.

For any information flow, mathematics is always the law hidden in the deepest.

For example, calculating the orbit of spacecraft, calculating the contraction channel of high-energy particles, and calculating the bond energy conversion during chemical reactions can all be completed through corresponding mathematical tools.

The conversion between brain wave neural signals and electrical signals is no exception.

Staring at the software interface opened on the screen, Xu Chuan muttered a sentence.

"If we want to eliminate the errors caused by the conversion conflict between the two mathematical models, the simplest way is to process the original data through the Euclidean distance and Pearson correlation coefficient."

"But before that, let's build a commonly used neuron model to process the signal data generated by the multi-electrode array reset mathematical model."

Thinking, Xu Chuan smiled.

There are still some differences between the simulated neural signal and electrical signal conversion theory established by basic quantum theory and the conventional neuron conversion model.

To ensure that there is no problem with the data converted by the former, the fastest way is to let these data go through the conventional neuron conversion model.
