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 force 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 be bent and twisted, 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 back of his hand and 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 fists, and pinching.
But it really did it, right under the noses of Xu Chuan and everyone.
Looking at this bionic robotic arm that was extremely dexterous and 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 problem now 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 disappeared, she jumped over with a smile 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 through neural signals. Whether it can be controlled synchronously is still unknown."
Xu Xiao smiled and said: "Brother Zheng, I have actually thought about this problem for a long time. Applying this bionic robotic arm to military equipment in a systematic way is not completely different."
"Huh? How do you say it?" 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 the 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's possible, but the brain-neural interface and bionic robotic arm we're currently researching are still far behind."
"If you want to implement this technology, there are two core issues. The first is that the feedback of external signals can be transmitted back to the brain in real time, clearly and stably, and it needs to be accepted by the brain and analyzed and processed at the same time."
"Such as vision, hearing, touch, smell and other senses."
"The second point is that if this technology encounters an electromagnetic attack, it is very likely that it will be scrapped directly."
"As 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 actually don't really recommend applying this technology to the military."

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 implement."
"What method?" Zheng Hai asked quickly.
Xu Xiao: "Synchronized exoskeleton!"
"Synchronized?"
"Yes! Synchronized!"
"To put it simply, on traditional exoskeleton wearable equipment, the nerve signals of limb activities are synchronized to the bionic exoskeleton device through the brain-computer interface chip, replacing the original intelligent sensing and AI control system."
"In this way, it will be more flexible than traditional exoskeleton devices, more adaptable to human body activities, and more adaptable to complex military operations."
"even!"
Speaking of this, Xu Xiao was already a little excited, his tone was a few degrees higher, and he waved his arms and said passionately: "We can even wrap the whole person with a complete exoskeleton device."
"In this way, the human body is inside and the exoskeleton completely covers the body. If we add suitable cushioning materials inside the exoskeleton, we can better cope with the damage of weapons."
"Of course, this kind of exoskeleton device is not strictly an exoskeleton device anymore. It should be called a single-soldier mecha!"
Hearing Xu Xiao's thoughts and seeing her excitement, Xu Chuan couldn't help but shake his head.
This girl has always liked whimsical and adventurous things since she was a child.
If she really got rid of a single-soldier mecha, her personal safety would be a big problem in the future.
To be honest, from a brother's perspective, he actually doesn't really want Xu Xiao to study these things.
Because if you touch it, you will definitely be targeted by CIA and other intelligence organizations and hostile countries.
Even if the country could protect Xu Xiao like it protected him.
But for anything, don’t be afraid of ten thousand, just be afraid of the eventuality.
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 produced by then, it will be on his head.
Anyway, he is not lacking in this achievement. He is not itchy when there are too many lice, and he is not worried about too many debts. He has long been on the CIA's focus list.
Even over there, he may be the target of special attention, and the other party has long been eager to kill him.
On the side, Zheng Hai's eyes lit up when he heard Xu Xiao's explanation.
He looked at Xu Xiao and said, "Do you need experimenters? I can help contact the military and arrange a few people to cooperate with your follow-up research?"
Before Xu Xiao could speak, Xu Chuan interrupted with a smile: "Let me handle this matter. Simply arranging a few people to cooperate in research is of little significance."
"Brother?" Xu Xiao looked over doubtfully.
Xu Chuan smiled and said: "Aside from personnel issues, don't underestimate the army's research and development capabilities."
"Whether it is the R&D 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 researches."
After saying that, he added something silently in his mind.
"In addition to research progress, these research institutions and universities can also share some of the fame and pressure from the outside world, and at least reduce the attention that overseas intelligence agencies pay to you, a silly girl."
"Reckless, ugh~"
Sighing, Xu Chuan shook his head and gathered his thoughts back.
Sometimes, being famous is really not a good thing. I just hope he can protect his time as much as possible.
...
At the foot of Purple Mountain, among the villas.
After taking a shower and wiping the water droplets off 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 SAS database integration platform, MathCAD, MATLAB and other software."
In the study room, a light voice soon sounded.
"Copy that, Master!"
The data files in the USB flash drive are some clinical experimental data from 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 fields such as data analysis, data mining, business intelligence and scientific research.
To solve the problems encountered during the use of brain-computer interface chips and bionic robotic arms, the first thing to do is to find the problem.
Of course, the problem is not that the signal transmitted from the brain-computer interface chip to the bionic robotic arm will have abnormal problems as Xu Xiao said.
Rather, it actually reflects a situation in these experimental data.
As for the direction of research, it is natural to start from the mathematical model of cranial nerve multi-electrode array reconstruction established by Xu Xiao and Liu Jiaxin, as well as the simulated nerve signals and electrical signal conversion of quantum theory that he had previously helped to study.
According to Xu Xiao, the problem most likely arises in the conversion of brain nerve signals by these two sets of mathematical models.
But for Xu Chuan, from a feeling point of view, he actually doesn’t think the problem will arise here.
Nothing more than confidence in my own research results.
It was not that he had never seen the mathematical model for resetting the multi-electrode array of cranial nerves. He had examined it in detail when he helped Xu Xiao solve the problem of simulating nerve signals and electrical signal conversion in quantum theory.
And with his character, it is impossible not to consider the problem of switching between the two when solving this problem.
But having an entry point is better than nothing.
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 data has been imported."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! In the study room, Xiao Ling's voice sounded, and Xu Chuan casually boasted: "It's amazing, so efficient."
"Thank you for the compliment, Master, Xiaoling will continue to work hard (??w??)?!"
Xu Chuan smiled, dragged the mouse, and opened the SAS database integration platform first, then his eyes fell on the data provided by Xu Xiao.
Compared with the problems in applied mathematics that he has solved in the past, the problem of conflicts 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 in what appears on the surface.
For any information flow, mathematics is always the deepest law.
For example, calculating the orbit of a spacecraft, calculating the contraction channels of high-energy particles, and calculating bond energy conversion during chemical reactions can all be completed through corresponding mathematical tools.
The conversion between brainwave neural signals and electrical signals is no exception.
Staring at the software interface opened on the screen, Xu Chuan muttered something.
"If you want to first eliminate the errors caused by transformation conflicts between the two mathematical models, the simplest way is to process the original data through Euclidean distance and Pearson correlation coefficient."
"But before that, let's build a recommended commonly used neuron model to process the signal data generated by resetting the mathematical model of the multi-electrode array."
Thinking about it, Xu Chuan raised a smile on his lips.
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 are no problems with the data converted by the former, the fastest way is to let the data go through the conventional neuron conversion model.
