Students in Ho Chi Minh City are researching drone technology to aid in firefighting.

(NLĐO) - Based on the reality of many fires occurring in narrow alleys where fire trucks are difficult to access, students in Ho Chi Minh City have created unmanned aerial vehicles (drones) to assist in firefighting.

On the morning of January 17th, the Ho Chi Minh City Department of Education and Training organized the selection round for projects and topics to participate in the national science and technology competition. Many student research topics demonstrated breakthroughs and high practical applicability, surprising the participants.

During the application review process, the organizing committee evaluated 1,574 projects, including over 300 individual projects, with approximately 2,850 students participating.

The interview round for the city-level science and technology competition took place over four days. The judging panel interviewed students directly from 1,574 qualified projects and selected 120 projects to advance to the national-level science and technology competition.

Mr. Nguyen Bao Quoc, Deputy Director of the Ho Chi Minh City Department of Education and Training, said that from these 120 projects, the judging panel will review and select the 13 most outstanding projects to represent Ho Chi Minh City in national and international competitions.

This year's national competition is scheduled to be held in Hanoi .

Many groundbreaking topics with high applicability.

Stemming from the fact that many fires occur in narrow alleys where fire trucks are difficult to access, two students, Trong Nhan and Van Toan, from Binh Chanh High School in Binh Chanh commune, came up with the idea of ​​creating an unmanned aerial vehicle (UAV) to assist in firefighting.

The two students are Trong Nhan and Van Toan.

Regarding their research, the two students explained that the device, designed as a drone, is capable of rapid access and two firefighting methods. Firstly, it uses a mechanism to drop fire-extinguishing balls onto the fire. Secondly, it uses a water spraying mechanism; the drone can directly draw water from the ground and spray it onto the fire. This method extends the operating time and ensures continuous firefighting.

In particular, the device was tested in a simulated fire scenario at the school with promising results. To overcome the limitations when encountering strong winds, the two students suggested integrating an automatic balancing system and wind sensors to adjust the motor speed, making the device more stable.

Two students, Cao Thắng and Quang Thắng, from Lê Hồng Phong High School for the Gifted, are researching the topic of predicting the risk of deforestation in Vietnam.

Forest loss risk forecasting system

Meanwhile, in another area, faced with the serious problem of deforestation, two students, Cao Thang and Quang Thang, from Le Hong Phong High School for the Gifted (Cho Quan Ward), researched a topic on predicting the risk of deforestation in Vietnam. "The group hopes to support forest rangers in being more proactive in forest protection," a representative of the research group stated.

According to the research team, most systems worldwide only detect deforestation after the forest area has already been damaged. The students proposed building a system capable of predicting the risk of deforestation before it occurs.

This study utilizes AI applications, specifically deep learning models, to analyze population density, urbanization levels, terrain slope, and radar imagery data. The system provides red alerts in high-risk areas, helping to predict the potential for deforestation in the coming months.

"Scientific research provides students with a meaningful learning journey. It's a process of applying knowledge, conducting in-depth research, gaining practical experience, and accepting mistakes to achieve the final result. This process fosters critical thinking, scientific working methods, and problem-solving abilities. This is an important foundation for their long-term personal development," said Mr. Nguyen Bao Quoc, Deputy Director of the Ho Chi Minh City Department of Education and Training.
