Chapter 268 I Have Fantasized About My Arms Countless Times

The equipment installation process lasted nearly two hours. During this process, Du Fuguo kept chatting with the three people, which surprised everyone.

The information they learned on TV before was one-sided—or at least incomplete. From the few thousand words of reports, they could never have imagined the character of this demining hero who did not hesitate to sacrifice for his comrades.

Optimistic, free and easy, full of a strange sense of humor unique to the Southwest, but at the same time has a wide range of knowledge, no matter what he is talking about, he can pick up a few sentences without hindrance.

However, he did not limit himself because of his knowledge. When talking about areas that he did not dabble in, most of the time he just asked questions and then listened silently.

After two hours, Zhu Xuan felt that he was almost overwhelmed by his charisma.

Looking at the beautiful girl sitting next to him again, there was a feeling in his eyes that it should be taken for granted.

After all the equipment was assembled, Zhu Xuan took Du Fuguo to a chair and sat down, then said:
"Du Ge, our robotic arm was originally designed with full-arm logic, that is, both the upper arm and the forearm. Now we have dealt with it according to your situation, but because the logic is damaged, it may take a certain amount of training time. — I’m talking about AI training time.”

"This process depends on luck. It may take several hours or ten minutes. You need to be patient and cooperate."

"Don't worry, I'm very patient in everything I do."

While speaking, Du Fuguo felt the pressure on his wrist, and then continued to ask:
"Can we start now?"

"Okay, what we have to do now is to let you adapt to the movement logic of this arm. Now you only have the right hand on the mechanical arm. You can try to move first, and use your left arm to sense the position and length of the mechanical arm."

"it is good."

Du Fuguo moved his arms, while Chen Li and the other three stared at the EGG signal display on the screen, and then the three were surprised to find that the strength of the opponent's EGG signal was much higher than that of ordinary people.

Numerous chaotic signals have begun to flow into the control program of the robotic arm through the decoder, and the wrist and fingers of the robotic arm have begun to move uncontrollably.

Zhu Xuan wanted to temporarily turn off the control function, but Chen Li raised his hand to stop him after thinking for a while.

"Don't move, this is a good thing. He has never used the arm controlled by BCI. The most important thing now is not to let him learn how to use it correctly, but to let him establish a general concept of the robotic arm."

"Although it seems that the movement is disordered now, after the skin of his left hand perceives the robotic arm, his brain will start to automatically build logic, and he will be able to learn to control it slowly."

Sure enough, as Chen Li expected, Du Fuguo was taken aback by the frantic movement of the robotic arm at first. When the fingers of the robotic arm touched his left forearm, it wasn't just his left hand that felt the tactile signal. , the electrical stimulation signal generated by the pressure sensor was also transmitted to his mutilated right arm.

More than a dozen electrodes distributed in different positions jumped wildly, which made him a little panicked.

But just a few seconds later, without even asking Chen Li, he already understood the meaning of this electrode.

This is to replace the tactile sense of the original palm with the tactile sense of other parts of the body.

The original prosthetic limb he used also had this function, but that prosthetic limb used sound waves to measure distance. As long as it sensed an object in front, it would make a short sound to remind him.

This method is very inefficient and has poor accuracy. Compared with it, he is more adaptable to the electrical stimulation method.

"Hey, your mechanical arm is really fine. Let me touch it."

"This is the index finger, ouch, you can't use force, it's a bit numb if you use too much force."

"Yes, the magnitude of the current is adjusted according to the magnitude of the pressure. You are pushing too hard."

"I can't help it. I can't control this right hand. Maybe it's the logic confusion you just said? I don't know if it's a thumb. Well, the feedback of the thumb is on the elbow joint."

"Middle finger. The feedback of the middle finger is on the upper arm. Oops, is this the second joint of the middle finger? There is feedback here too?"

Chen Li glanced at the EGG signal diagram on the screen, and then replied:
"Yes, this design is mainly for the convenience of grasping objects with a relatively small diameter, like the pen Zhu Xuan mentioned before."

"That's great, Dr. Chen, I can probably understand how to operate this robotic arm, but the difficulty of this exercise is not low."

"It's really not low. To be honest, if you want to fully adapt to this robotic arm, it will take more than a year to conservatively estimate."

"One year, don't worry, I won't take that long—give me three months."

With a confident smile on Du Fuguo's face, he continued to experiment with the robotic arm.

Chen Li found that he didn't even need to give the other party any instructions, as if he had some kind of talent, he naturally learned a whole set of practice ideas.

I saw that he first used his left arm to help the mechanical arm to bend the other four fingers, leaving only one index finger extended, and then tried hard to control the movement of the index finger to tap his left hand.

In the very beginning, it took him several minutes to successfully control the tap of his index finger, but from his face, Chen Li could not see any disappointment.

He is just trying persistently, as if he is doing an extremely difficult but extremely great thing.
-
However, it's really great.

Chen Li had a hunch in his heart that his name would appear in the future history of science and technology even if all the heroic deeds of the other party were left aside.

Because he will be the first person to use an artificial robotic arm proficiently, and use it without visual feedback.

This will set a solid milestone for the BCI career in China, because apart from technology, he will rely on himself to prove a thing that everyone is looking forward to but no one dares to confirm.

That is, humans and machines can co-exist and cooperate.

Half an hour later, Du Fuguo was able to control the flexion and extension of his index finger proficiently. He even patted the girl beside him with his left hand, and touched her palm with his index finger.

The girl took advantage of the opportunity to hold the mechanical finger, Du Fuguo laughed a few times, then broke free and said:
"Don't push so hard, the current is too high. Dr. Chen, can the current be lowered later?"

"This can be adjusted according to your own needs, but at the beginning, I suggest that you adjust it a little bit larger, which will help your study."

"Understood, then keep it the same."

As he spoke, Du Fuguo put away his index finger, then stretched out his middle finger with difficulty, and began to repeat the same movements as his index finger.

The EGG signal on the screen is becoming more and more stable. The artificial intelligence algorithm collects a large number of data sets in a short period of time, and begins to correct the operating habits. Useless signals are eliminated, and the weight of typical signals is increased. With the cooperation of technology and will Under the circumstances, only three hours later, Du Fuguo has completed the control of the entire right palm, and began to try to exercise his wrist.

"It's unbelievable, Brother Du. It took me several days to learn how to control the robotic arm."

"Because I'm smart."

Du Fuguo replied with a smile.

"It's not just smart anymore, it feels like talent."

Zhu Xuan looked at the screen while talking, and the moment his eyes swept over Chu Ya who had been standing beside him, he suddenly noticed that the other party's expression was a little strange.

That wasn't a look of surprise.

But expected?

Chu Ya noticed his gaze, and quietly raised her finger to point to her head. Zhu Xuan was taken aback for a moment, as if a flash of lightning flashed in his consciousness.

He suddenly understood.

This is not a talent at all, but, during the period of losing his arm, the other party has imagined and simulated such scenes in his mind countless times.
