Shen Yin handed the car to Wu Xu, Wu Xu was overjoyed, skillfully found the clockwork, then tightened it, and began to watch the car move.

Shen Yin handed the puppeteer to Wu Yuanyuan again: "Yuanyuan is a girl, I thought that I might not like cars, so I made this puppeteer who can dance, you try it quietly, this puppeteer can dance." ”

Although the puppet dancing is a bit stiff, it can really dance, at least Wu Yuanyuan is happy to watch.

Wu Xiangchang, who was originally chatting with Grandpa Shen on the side, paid attention to this place, found out about the situation here, came over, looked at the car and the puppet, Wu Xiangchang said to his son: "Son, let Dad try it." ”

Wu Xu glanced at Wu Xiangchang and sneered: "Dad, you even want to grab toys from me and play with them, it's okay for you to play, but this is made for me by Sakura, you can't put it away." ”

Wu Xiangchang patted Wu Xu's head: "What do you say, do you think your father will covet your little gadget, it will naturally be useful for me to try." ”

Wu Xu was dissatisfied: "Try it, just try it, what are you doing on my head, I'm going to be stupid, you help me do my homework." ”

Just as the car stopped, Wu Xiangchang took it as he thought, tried to calm the clockwork, and then put it on the ground, watching the car move slowly.

This car is nothing, what makes Wu Xiangchang find it strange is that this car will automatically avoid obstacles when it encounters them, and this technology is only afraid that it has not been seen abroad now.

"Sakura, why didn't this car hit the table legs and stool legs on the side or something?" Wu Xiangchang asked, but he seemed to be thinking about something in his heart.

Shen Yin glanced at Wu Xiangchang, she didn't expect Wu Xiangchang to find out this, but for Shen Yin, this is not a secret that cannot be said, just find it if you find it, so she replied: "I installed a circuit board in this car that no one else wants, and I found it at the scrap yard."

I just changed the function of the electronic capacitor inside, so that they have an extra function to automatically avoid obstacles within fifty centimeters, but this function is a bit rough, after all, these things are made of waste materials, so whether it is a car or a puppet, the action is a little slow, but the recognition rate is still there. ”

Shen Yin had a very calm expression and pointed to the puppeteer on the side: "It's like a round puppeteer, it can dance, it can spin, and when it meets someone on the side, it will automatically avoid a reason, although it is stiff, but it is better than nothing." ”

Wu Xiangchang was shocked: "Then can this technology be used in other places?" ”

"Somewhere else?" Shen Yin tilted his head and looked at Wu Xiangchang: "What place?" ”

"Like some radar?" Wu Xiangchang continued to ask.

"It can be, and the radar itself has the function of scanning the surrounding obstacles, my thing is also a rough thing, and the radar is a detailed thing, but the theory and drawings can be cited."

Shen Yin knew that radar was first invented by the world-famous physicist Doppler in 1842, but now Kyushu's radar is not as advanced as abroad.

In fact, Shen Yin only made this toy because she happened to find that the things on those discarded circuit boards could be modified for this function, so she used it, and now looking at Wu Xiangchang's eyes, she knows what Wu Xiangchang means.

Shen Yin thought for a while, and then said, "I can draw a drawing, and you will take it away from my uncle in a while, and I don't care who I give it to." ”

His uncle is a veteran, and Wu Xiangchang retired because he was injured and had to retire, otherwise he is now also a dignified battlefield general.

Now that he has retired from the army, he is also one of the people in charge of the team, so he still has a lot of connections, and these connections are all public connections.

Shen Yin's drawing can be said to be a boost to the development of the entire Kyushu radar.

Wu Xiangchang knew this, so he opened his mouth to discuss with Shen Yin, but he didn't expect Shen Yin to be so generous, he went back to the room directly to draw drawings, and made a detailed explanation, and gave Wu Xiangchang before Wu Xiangchang and his family left.

Wu Xiangchang took the drawings, and immediately went to his former boss and gave him the drawings, of course, he also brought Wu Xu's toy car over, of course, this is borrowed, and it will be returned to Wu Xu when the time comes.

Looking at the way the toy car avoids the obstacles in front of it, although it is not particularly sensitive, it also shows the preciousness of this drawing.

"This is really your niece's drawing." Wu Xiangchang's boss is surnamed Liao, and his name is Liao Jiacheng, who is in charge of local security.

Wu Xiangchang nodded slightly: "She is my wife's niece, counting, your father should have heard of it, that is, Shen Weiguo." ”

"Martyr Shen Weiguo?" Liao Jiacheng was slightly stunned, and then smiled: "I didn't expect this Shen Weiguo to have such a girl, how old is it?" ”

Wu Xiangchang glanced at Liao Jiacheng strangely: "At the age of seven, he is only in the first grade, but he has already completed the junior high school course, and it is said that he plans to study the high school course by himself after a while." ”

"Seven...... Year? Liao Jiacheng looked at Wu Xiang for a long time, looking like you were joking.

Wu Xiangchang said very calmly: "It's really seven years old, or seven years old after the Mid-Autumn Festival, boss, this is actually nothing." ”

Wu Xiangchang took a pack of big front doors in front of Liao Jiacheng, and then picked one before saying: "You also know that young geniuses already exist, and my niece should be such a person."

Not to mention this drawing and doll, some time ago, when she was busy with farming, she saw my father-in-law cutting rice hard, so she made a manual harvester, and some time ago, thinking that the typhoon was affected, causing the radio signal to not be received, she made a signal receiver.

Now Shen Baozhu, the village head of Shenqiu Village, is running around for the village factory of this receiver, it is said that the procedures have come down, and now the material problem is running, which is basically the same, if it goes well, a village factory can be set up at the end of the year. ”

Liao Jiacheng naturally heard about this: "I have also heard about the village-run factory of the signal receiver, after all, it is related to the signal, so I have also investigated and know that the receiver's acceptance signal is for the radio, so I have no objection, I can't imagine that this is also your niece made up." ”

Wu Xiangchang hummed, knocked a few times with a cigarette, but did not put it to his mouth, Liao Jiacheng saw this and said: "You can smoke if you want." ”

Wu Xiangchang smiled: "My daughter-in-law doesn't let me smoke, saying that smoking is not good for my health, so unless I am in a panic when I am sleepy for a long time, I will smoke a pick-me-up on the side of the road, and I don't smoke at other times. ”
