The ups and downs of life in the Siheyuan

The next morning, Li Yuanxian went to the laboratory to check the work and found that everything was carried out step by step, so he returned home.

With experience in lower limb control, it is relatively easy to conduct upper limb experiments.

Silver needles are rarely used to prick the opponent's muscles. Instead, the sensor is placed on the skin and the electromyographic signal can be analyzed through an oscilloscope.

Gao Jun suffered significantly less pain than Uncle Song.

Gao Jun, who was informed of the pain in advance, looked at Uncle Song with a joking look on his face, which made Uncle Song very angry every time.

This person is older and should be more calm, but now I find that they are more easily moved emotionally.

This is especially true when old people get together.

Now there is an aluminum alloy arm on Gao Jun's arm, which is directly tied to his upper arm.

In order to reduce weight and reduce the burden on the upper arm, the arm's skeleton is relatively simple, an aluminum alloy frame with elbows, wrists and hands.

For more flexibility, the palm and 5 fingers are designed.

What can move is the elbow and fingers.

The fingers are the same as a real person and have 3 joints.

The elbow is a hydraulic joint, and the movement of each finger relies on a traction rope and spring. There are five sets of traction ropes and springs in total.

Therefore, all 5 fingers can move independently.

At the finger joint is a strong spring that causes all fingers to contract. A strong string is attached to the back of the finger, and five silent motors are spread across the forearm.

All fingers are initially in a fist state. If any finger is straightened, just tighten the corresponding string.

The more string is wrapped around the motor, the straighter the finger will be. vice versa.

Currently we can only do this step because the fingers are very flexible and have dense muscle groups and nerve networks.

It is not yet easy to completely simulate fingers.

Even so, it brought considerable difficulties to Li Yuan. He needed to find the electromyographic signal that drives finger movement.

Since only a section of the upper arm was preserved, the electromyographic signals of some muscles were unclear. Li Yuan combined the signals on the shoulder for comprehensive analysis.

This was a repetitive and boring job. Within a week, Li Yuan recorded a large number of signal characteristics.

For example, Gao Jun was asked to bend his thumb and get a set of signals.

Bend your middle finger and get another set of signals.

These two sets of signals have too many repeated signals, making it difficult to distinguish dedicated signals.

All cell phone signals, repeat more.

Li Yuan directly handed over these analysis and differentiation matters to Nuwa No. 1, and he began to consider cases in which part or all of the forearm was still preserved.

I originally thought about using Uncle Song to simulate it, but gave up after thinking about it.

With the deepening of the research, comparing Uncle Song's electromyographic signals at the corresponding positions, it can be said that they are quite different from those of Gao Jun.

And he also found that some location signals tended to gradually strengthen during the process of exploration.

Although this trend is very weak, Li Yuan still discovered it with his keen perception.

He had a bold guess that maybe when some parts of the muscles are lost and the normal nerve network is interrupted, new nerve networks will slowly grow under the stimulation of the brain.

This can be seen from the many inconsistencies between the EMG signals of Uncle Song and Gao Jun.

The performance of the upper arm EMG signals of Wei Min and Song Shu were basically the same.

Throughout the process, Weimin was very interested in the smart arm.

I go home from school every day, finish my homework quickly, and then run to Li Yuan's studio or sunroom to help Li Yuan.

Seeing that he was interested in technology, Li Yuan secretly sighed that there would be a successor.

Now the children are older, Weimin is in the first grade of high school, and Lele just entered college this year.

With Li Yuan's excellent genes, he is a leader in both studies and sports.

If the three children apply for sports specialties, there will be no problem.

Under the influence of Li Yuan, Lele chose the Kyoto Aviation College (formerly known as Beihang University), which was far inferior, with her top score in science in Kyoto.

This made his head teacher very confused. When he found Li Yuan, he was dismissed by saying, "I respect my children."

On Sunday, while he was busy, Representative Tong approached Li Yuan.

"Lao Li, I'll pick you up at 6 o'clock tomorrow morning. Remember to stay alert."

"What do you mean, are you trying to introduce someone to me?"

"Yang Ting, Yang Ting, come on, your old Li wants Hongxing to come out of the wall!" Representative Tong shouted towards the grape trellis.

When I came in just now, Yang Ting was working with Miss Xiao Lu under the grape trellis.

Yang Ting raised her head and shouted toward the study: "Really? Then introduce a few more."

After saying that, there was a burst of laughter in the courtyard.

"Auntie, you are too open-minded. My mother said that men have to take care of things."

"Hey, I still don't know what kind of person your uncle is. He is focused on work."

"Then don't be afraid of ten thousand, but be afraid of the worst!"

"Your uncle is not an ordinary person. Ordinary women cannot catch his eye."

The little girl looked at her aunt, whose skin was more delicate than hers, and seemed to understand something.

In the room, after hearing Yang Ting's reply, Representative Tong wanted to make some jokes, but was interrupted by Li Yuan.

"Okay, tell me, what's going on? Don't you see, I'm very busy right now."

"It's a good thing anyway, remember to dress up nicely."

Without waiting for Li Yuan's reply, he hurriedly walked out of the study.

Li Yuan looked at his back and blurted out "something wrong".

Representative Tong who came to the hospital was worried about finding Yang Ting.

"Xiao Yang, you are going to see the leader tomorrow. Remember to help your family take care of themselves."

"Okay! You are in a hurry, have lunch before leaving." Yang Ting stood up to treat the guests.

"No, there are a lot of things today. Otherwise, I will definitely try Xiao Yang's craftsmanship."

"Well, you're busy. We are not outsiders. If you want to come and eat, I'm more than happy to do so."

"Okay, just say this to Xiao Yang, and I will forgive Lao Li for being rude."

"It's too boring!" Li Yuan's impatient voice came from the study.

Hey, hey, representative Tong said hello and left.

Li Yuan didn't take it seriously, but Yang Ting took it seriously.

He went back to the bedroom to rummage and took out a crisp suit, tie and white shirt.

After thinking about it, he took out Li Yuan's favorite tunic suit.

Come to the study room.

"Lao Li, which outfit will you wear tomorrow?"

Looking up at Yang Ting's quiet and serious expression, Li Yuan stopped being casual.

Look at two outfits and think, "Wear a suit."

"Don't you usually like to wear a Chinese tunic suit when attending formal occasions in China?"

“Nowadays, wearing a suit can be regarded as a sign of ideological liberation. This is the trend now.

Please help me ask where to make authentic Hanfu in Kyoto.

I need to prepare more and have matching items for various occasions.

From now on, I will be the spokesperson for Hanfu."

"Which song are you singing?"

"Hey, times have changed, and the methods of bandits have also changed. I want to add a different voice to the future.

In the future, I will start a magazine with the purpose of promoting China’s great history, technology and civilization.”

"Ah, aren't you a science major?"

"Hey, it's not like you don't know how powerful I am." After saying that, he stood up, hugged Yang Ting and kissed her.
