Great Power Technology

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

The information they had learned on TV before was one-sided - or at least incomplete. From the reports of a few thousand words, they could not imagine that this demining hero who did not hesitate to sacrifice for his comrades had such a character.

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

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

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

Looking at the beautiful girl sitting next to him again, there was a sense in his eyes that it was natural and should be like this.

After all the equipment was assembled, Zhu Xuan pulled Du Fuguo to a chair and sat down, and then said:

"Brother Du, our robotic arm was originally designed with full-arm logic, that is, both the upper arm and the lower arm. Now we have dealt with it based on your situation, but because the logic is damaged, it may require a certain amount of training time. ——I’m talking about the training time of artificial intelligence.”

"This process depends on luck. It may take several hours or more than ten minutes. It requires your patience and cooperation."

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

As he spoke, Du Fuguo felt the pressure on his wrist, and then continued to ask:

"Can we start now?"

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

"good."

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

Many 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 moment.

"Don't move. This is a good thing. He has never used a BCI-controlled arm. 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 the movement seems chaotic now, after the skin of his left hand senses the robotic arm, his brain will automatically start to establish logic, and he will slowly learn to control it."

Sure enough, just as Chen Li expected, Du Fuguo was startled by the erratic robotic arm at first. When the fingers of the robotic arm touched his left forearm, it was not just his left hand that felt the tactile signal. , the electrical stimulation signal generated by the pressure sensor was also transmitted to the incomplete arm of his right hand.

More than a dozen electrodes distributed in different locations were jumping wildly, which made him a little panicked.

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

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

The prosthetic limb he originally used also had such a function, but that prosthetic limb used sonic ranging. As long as it sensed an object in front of him, it would make a short sound to remind him.

This method is very inefficient and has poor accuracy. In comparison, he is more adaptable to electrical stimulation.

"Hey, your robotic arm is really finely made. Let me touch it."

"This is your index finger. Oops, don't use force. It'll be numb if you use too much force."

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

"I can't help it. I can't control this right hand. Maybe it's the logical confusion you just mentioned? I didn't know it was the 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? Is there feedback here too?"

Chen Li glanced at the EGG signal diagram on the screen, and then replied:

"Yes, this design is mainly to make it easier to grasp objects with smaller diameters, like the pens Zhu Xuan mentioned before."

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

"It's really not low. To be honest, it will take more than a year for you to completely adapt to this robotic arm."

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

Du Fuguo showed a confident smile on his face, and then continued to invest in experiments on the robotic arm.

Chen Li found that he didn't even need to give any instructions to the other party. He seemed to have some kind of talent and naturally learned a whole set of practice ideas.

I saw that he first used his left arm to help the robotic arm to bend the other four fingers, leaving only one index finger stretched out. Then he worked hard to control the movement of the index finger to tap his left hand.

At the beginning, it took him several minutes to successfully control the tapping of his index finger, but Chen Li could not see any disappointment on his face.

He was just trying perseveringly, as if he was doing something extremely difficult but extremely great.

——

However, it is indeed great.

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

Because he will be the first person to skillfully use an artificial robotic arm without visual feedback.

This will lay a solid milestone for the domestic BCI career, because in addition to technology, he will rely on himself to prove something that everyone is looking forward to, but no one dares to confirm.

That is, humans and machines can cooperate symbiotically.

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

The girl took advantage of the situation and held the mechanical finger. Du Fuguo laughed a few times, then broke away and said:

"Don't use so much force, the current is very strong. Dr. Chen, can the current be turned down a little later?"

"This can be adjusted according to your own needs, but in the early stage I suggest you turn it up slightly, which will help your learning."

"Understood, let's 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 collected a large number of data sets in a short period of time and began to correct operating habits. Useless signals were eliminated and typical signals were given increased weight. With the cooperation of technology and will, In just three hours, Du Fuguo had completed control of the entire right palm and began to try to move his wrist.

"It's a bit incredible, Brother Du. It took me several days to learn to control the robotic arm."

"Because I'm smart."

Du Fuguo replied with a smile.

"This is more than just smart, it feels like talent."

Zhu Xuan looked at the screen as he spoke. The moment his eyes glanced at Chu Ya, who had been standing next to him, he suddenly found that the other person's expression was a little strange.

It wasn't an expression of surprise.

But is it expected?

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

It dawned on him.

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