Won the 24th China Robot and Artificial Intelligence Competition

All -terrain car design and production race

Third in the country!

They are the School of Information Science and Engineering

Automation Department 2019 undergraduate student

Zhang Ziyi

Ding Rou

Jiao Rongchang

Today, Star Morphine takes you into the story behind them!

"It is very interesting like an upgrade like a monster!"

Because of a course, it has an inextricable bond with the single machine. "We have a strong interest in the single -chip microcomputer in the comprehensive experimental class of Mr. Xu Yalan, and this competition is a good opportunity to put the theory into practice." Participants all think that the competition is very interesting, In their opinion, this is also an interesting "game" and enjoy it. To participate in the competition, the team members must first carry out the design and production of the all -terrain cars. From the overall construction of mechanical parts in the early stage, to the code operation debugging, complete the track tasks, through the three -barrier task of narrow bridges, steps and tunnels. Balloon. "It is very interesting to complete each task. It is very interesting like an upgrade." Captain Zhang Ziyi said.

The preparation of the race requires a lot of time and experience. Each of them strives to balance academic and competitions, and do experiments under the guidance of the teacher after learning. But the cause of the epidemic, their experiments also face many difficulties and inconveniences. "When the epidemic is the worst, because the epidemic prevention and control needs, the actual time to stay in the laboratory is not long, so the debugging of the car in the provincial competition is not ideal." Talking about the impact of the epidemic, the captain's captain, the captain Zhang Ziyi said with a smile that it was these obstacles that made this experience precious.

When the epidemic is not serious, the team members cherish the opportunity to do experiments. In the morning, they got up early, assembled, and stayed in the laboratory until ten o'clock in the evening before returning to the bedroom. "There is sufficient debugging to find problems. A little bit of improvement and improvement of the performance of the car."

All -terrain small car system structure

In addition to external factors, the players also encountered many difficult problems in actual operation. For example, when the car that was initially designed was straight, there would always be a large offset and could not complete the straight line walk. This will cause the car to not trace normally at the steps down, affecting stability. After discovering the problem, the team members immediately started to find a solution.

Maybe there is a gap between the speed of wheels on both sides? Soon, the players excluded this possibility through the speed measurement sensor.

Is there a problem with the mechanical structure of the car? After repeated experiments, there are indeed unreasonable structures, so they constantly change the plan and adjust the mechanical structure of the car, and finally the car no longer shifts in a straight line.

In this way, facing the misunderstanding in the pipeline, the instability of the upper and lower steps, and the large deviation of the line patrol, repeated trial and error, repeated modification, the performance of all aspects of the car finally reached the expectations of the players, and the various settings can be efficiently completed. Task.

After several months of preparation, the national finals finally came.

"I don't want to, focus on the game, devote myself!"

Although confident and looking forward to, in the national competition, the players are still very nervous. "The national competition is different from the provincial competition. The provincial competition is a Monteric style system. You can continuously record videos and select the best competition. The national competition is online live broadcast. He is on the spot. "The team member Jiao Rongchang introduced.

"We are the second group. There were some mistakes in the first group, which also relieved our pressure to a certain extent." The only female player Ding Rou laughed with a smile.

"I don't want to, focus on the game, and devote themselves." After the rapid adjustment state, when they were turn to play, all the players overcome their tension.

There are two fixed aircraft positions and two mobility positions in the competition field. After the start of the game, the car starts at the start line and automatically drives. Artificial intervention is not allowed throughout the process. It is not until the car completes all obstacles and reaches the end of the line. The referee reports the time for the time. After the team members confirm that they are correct, the game is officially ended.

Overall structure of a car

Throughout the competition, the car designed and produced by the Zhongshi team showed a very good stability, performed well throughout the process, and perfectly completed various track tasks.

After the intense and fierce competition, Zhang Ziyi, Ding Rou, and Jiao Rongchang finally got their wishes. In the midsummer this year, they harvested the fruitful fruits they expect! They expressed their gratitude for the opportunity to provide the college and school, and thanked Teacher Xu Yalan and Teacher Wan Xin for their careful guidance.

"I have a deeper understanding of the" details determine success or failure '! "

Looking back at the entire game, constantly testing, and eliminating the failure over and over again, it has greatly improved the overall stability of the design of the car. They have a deeper understanding of the "details determine success or failure".

The team members can't help but feel sighed, "At the beginning, we all think that the game is not difficult, and it should not need to spend much energy to complete it. But if you really do it, you can find that if you want to achieve good results, every detail must be processed. One Details can cause a loss of work and loss. This requires patience and energy. "

For the three students, this competition has not only received an academic honor, but also has accumulated experience and strength in the long way to grow.Zhang Ziyi said that this competition gave himself a chance to analyze and understand his professional opportunities from different dimensions, so that he strengthened his choice more.

Ding Rou felt that he not only improved his professional skills in this competition, but also gained friendship and tacit understanding, and found like -minded friends in the constant running -in.

Jiao Rongchang believes that the competition makes him pay more attention to the practicality and application of learning.

In the future, all three students hope to continue to study in their professional fields, learn more theoretical knowledge, participate in more practice, go to their own love, and work hard.

Dream

Not only the heart

Be brave into action

Keep refueling, good youth!
