country made

Not long after the start of the second semester, all junior high schools and high schools across the country received a notification.

The China Association for Science and Technology issued a notice to all middle schools through the Education Bureau, deciding to hold the first National Robotics Competition for Middle School Students next month.

This matter will go back to the time when Ji Yu participated in the Fusang Science and Technology Exhibition. Since then, the China Association for Science and Technology has been paying attention to him, and then the China Association for Science and Technology discovered his article "Simple Intelligence of Robots".

The China Association for Science and Technology has been committed to popularizing various scientific knowledge to young people, but the "Science Journal" published by them is too formal, ordinary people can't understand it, and it has never been popularized among college students, let alone elementary and middle school students.

The thesis written by Ji Lian is based on the practical courses of later generations of students. As long as the tools are prepared as written in the thesis, and then follow the steps, the students can complete the assembly of an intelligent robot by themselves.

The China Association for Science and Technology seems to have received a slap in the face, and finally found a way to popularize science to primary and middle school students.Then in this year, the China Association for Science and Technology imitated Ji Yu’s paper and also compiled a science book, which briefly described various scientific knowledge in a language that elementary and middle school students can understand, and accompanied it with detailed descriptions of various small scientific experiments. , the title of the book is "Learn Science with Me", and the book cover adopts the animation color pictures that students like for the first time.

The book became very popular after it was released, and many primary and secondary schools actively recommended it to students, and parents were willing to buy it after reading it. It has become the most popular extracurricular reading for parents and children this year.

However, after a period of investigation, the China Association for Science and Technology found that parents bought it, and children watched it, but few people tried those small scientific experiments.

These scientific experiments do not require many tools, but not every family has them. If you want to experiment, you still need money to buy them.Most parents support their children's reading, but they don't pay much attention to manual experiments, especially these experiments cost money.

The China Association for Science and Technology felt that the goal of popularizing science had not been fully achieved, so after discussing with the Education Bureau, it decided to hold a robot competition for middle school students to promote students' enthusiasm for science and their hands-on ability.

Fuso's Asia-Pacific Robot Competition was started in 88, the International Robot Soccer Competition was proposed in 92, and it was not implemented until 93. The American BotBall International Robot Competition was held for the first time in 97.At present, no country in the world has held a robot competition. The robot competition held by the China Association for Science and Technology is definitely a pioneering initiative.

However, this also confused the middle schools. When it comes to sports competitions, or math, physics, and composition competitions, everyone is familiar with it and knows how to participate.

I've never heard of a robot contest, what should I compare it to?

Fortunately, the China Association for Science and Technology quickly distributed the competition tutorial, and the schools knew what to do.

Like other competitions, Yigao responded positively and immediately organized a participating team.

"Ji Yu, Song Jining, come here."

Ji Yu and Song Jining, who were in class, were suddenly called out by the physics teacher. They looked at each other and followed suspiciously.

Those who were called to the staff room, besides the two of them, there were also several senior seniors, all of them looked puzzled.

Mr. Gu, who was in charge of senior high school physics, sat behind his desk and looked at the students recommended by all the physics teachers. He turned his eyes around Ji Yu and slowly explained the reason for calling them.

When they first heard about the robot competition, all the students except Ji Yu and Song Jining were extremely surprised.

"Robots? Transformers?"

Transformers animation is now popular all over the country, causing many teenagers to think that robots look like Transformers.

"Unfortunately, there are no such advanced robots, although I also like Transformers." Teacher Gu took out a very cute book with colorful animation patterns on it, which looks like a kindergarten teacher. I study science".

"You don't need to participate in the school's courses for the next month, I will teach you how to make robots." He looked at Ji Yu and the two: "Of course, I think Ji Yu and Song Jining should know more about this than me. I need your help."

Ji Yu and Song Jining nodded together: "No problem."

A senior high school student pushed his glasses and asked, "Mr. Gu, can I refuse? I'm going to take the college entrance examination soon, and I don't want to be distracted by unnecessary competitions."

Teacher Gu said: "According to the notice issued by the Ministry of Education, students who participate in the National Robot Contest and get a place can get a maximum of 20 points in their files."

This is why, except for Ji Yu and Song Jining, all the other contestants are high school seniors.Hearing can add points, the students no longer have opinions, but are full of fighting spirit.

Then, under the guidance of two physics teachers, these more than ten students started targeted emergency training.

The book "Learn Science with Me" is written in a simple and easy-to-understand manner. Everyone is a top student in physics. Following the experimental steps written in the book, various small electronics were quickly made.

But doing this alone is not enough, because all schools are using the reference book "Science with Me", and the end result is similar.

Teacher Gu knows that Ji Yu and Song Jining have participated in the research of robots, and even defeated the robots of the Fusang Kingdom, so they rely heavily on them. Every time they conduct experiments, other students mainly teach, but they are completely consultative to Ji Yu. : "What do you think of Ji Yu? What do you think of Song Jining?"

Some students couldn't help protesting: "Teacher, why do we need to add two first grades to such an important national competition? What if we are delayed?"

Teacher Gu asked them: "Is there a time when the two of them couldn't answer the question I asked?"

The students thought for a while, shook their heads, and said again: "But we can also answer it, isn't it just some electronic principles!"

"Yes, you can answer it, can't other schools answer it?"

Seeing the students thinking, Teacher Gu continued: "You will, Ji Yu and Song Jining will. You won't, Ji Yu and Song Jining will too."

Although Teacher Gu is an excellent physics teacher, he is only a high school teacher after all, and he doesn't know much about robots.All he can do is to teach the students to practice according to the cases in the book.

Whatever he took to participate in the robot competition, he simply handed it over to Ji Zhuan and Song Jining who had defeated Fusang.

Song Jining asked Ji Yu: "Yuanyuan, what robot do you want to use for the competition?"

Without even thinking about it, Ji Yu immediately replied, "Snake-shaped robot."

No way, he is best at only two kinds of spider-like robots and snake-like robots.

The spider-shaped robot has been given to Grandpa Lu, and now the research institutes are almost finished, and the snake-shaped robot can also start.

Snake-shaped robots are actually better than spider-shaped robots. In 72, Fuso University of Science and Technology developed the first snake-shaped robot with a speed of 40 cm/s. It is the most basic robot that can only run on barrier-free flat ground. . In 2000, the United States developed a snake-shaped robot that can explore outer space. Since then, the snake-shaped robot has become the most common exploration robot in all countries.Huaguo is a snake-like robot that can move on the water surface only developed in 2002, and the development time was half a year.

With Huaguo's current level of technology, it should be possible to make it if there are principles and blueprints.But No. [-] High School is just a high school after all, and with the greatest assistance the school can give, what Ji Zhuan produced is just the simplest robot composed of a single-chip microcomputer.

Even such a simple robot shocked the entire team.

"My god, my god, it really moves like a snake, it really moves! Why, why, it obviously has no wheels!"

Xu Zehua, who had previously protested against Ji Rafter's special care, looked excited and grabbed him and kept asking why.

Song Jining unscrewed his hand and said to Mr. Gu: "Teacher, this is the finished product and design drawing made by Ji Yu and I. Because we are not sure whether the competition requires on-site production, we will disassemble it and teach you how to make it." , ask the teacher for assistance."

"Take it apart? No, no, don't take it apart." Teacher Gu stopped immediately, with a look of reluctance: "It's a pity to take it apart, what if it is accidentally broken! I will apply for funding from the school again and buy a few more." The kit has been remade."

Although the school supports students to participate in competitions, they used to be sports, composition and other competitions, which never required much funding, so the funding this time was also limited.When Teacher Gu applied for funding from the principal again, he was reprimanded. Then Teacher Gu showed off the snake-shaped robot, and the principal immediately increased the competition funds.

The national competition is one month later, but in fact, the regional knockout competition started half a month later.Because most schools do not understand robots, the only reference is the book written by the China Association for Science and Technology, and the paper "Simple Intelligence of Robots" recommended by the China Association for Science and Technology.

Therefore, regardless of high school or middle school, all participating schools did similar things, some made minor improvements, and some completely copied the experimental cases in the book.The part that can really be called a competition is to see which participating team has the fastest production time and the smallest technical error.

The participating teams of No. 1 High School are high-achieving students themselves, and they have also received Ji Zhuan's teachings on the technology of later generations. They don't need Ji Zhuan to show up, let alone take out snake-shaped robots. Just relying on their own level, they won the No. [-] place in the district. Achievements, and successfully won the National Middle School Student Robot Contest admission ticket.

At the International Airport in City A, a young man about 27 or [-] years old walked out of the airport, wearing blue jeans, a black lapel T-shirt, and a popular mid-section peach heart.

He stood at the gate of the airport, looking at the flow of people coming and going, and suddenly saw a scrap of paper on the ground in the distance, and immediately showed disgust in his eyes: "Tsk, you are still so unqualified, I really don't want to come back."

He didn't stand for long, and soon another young man of similar age came over: "Zhao Wei, wait a long time, I'm sorry I'm late."

Zhao Wei pulled out a smile: "My current English name is Abner, and I am more used to being called by my English name."

"Ah?" The young man who came to pick him up was stunned, and said, "That's troublesome, you know I'm not good at English, so I'd better call you Zhao Wei...Why are you dressed so strangely?"

The lapel T-shirt on Zhao Wei's body is normal, but the jeans are very baggy and long, and they are piled up layer after layer at the ankle.

"What's so strange?" Zhao Wei said dissatisfied, as if he had been stepped on sore feet: "This is New York clothing, understand? This kind of loose jeans with piled feet is popular now. It represents the freedom and unrestrainedness of young people. I I said it earlier, Zhang Limin, you should go to the United States to see more fashion. Look at your clothes, they are dusty all day long."

"Okay, okay, you are free and unrestrained." Zhang Limin was too lazy to argue with him, and helped him carry his luggage: "Let's go, let's go, the car is waiting outside."

Zhang Limin had already hailed a taxi, and when leading Zhao Wei into the car, he pointed to the row of taxis parked outside the airport and said, "Look, there are more and more taxis now, and taking a taxi is much more convenient than before."

"Oh." Zhao Wei dismissed it, wanting to say that every family in Meidi has a private car!He opened his mouth, thinking it was useless to say it, Huaguo is so poor, there is nothing comparable, so he just shut up and got in the car.

As the taxi drove into the urban area, Zhao Wei suddenly saw the red banner hanging on the street through the car window.

Warmly celebrate the start of the finals of the first National Robotics Contest for Middle School Students.

"National Robot Contest for Middle School Students?" Zhao Wei looked at the banner on the wall with a look of contempt: "What the hell?"

At this moment, Ji Yu was also saying, "What the hell is Abner?"

Because he passed the regional preliminary competition, Yigao entered the national finals and will go to the stadium in City A to participate in the finals.Afraid of being bored on the train, Ji Chen bought a magazine.

Then, Ji Yu turned to an article.
