Elementary school children from central Vietnam achieved a first prize with their convenient waste treatment plant model in the final round of a national robot competition in Ho Chi Minh City on Saturday.

The trio of Hoang Phuong, Nhu Quynh and Long Vu from Thua Thien-Hue Province beat the other 111 contestants to bring home the grand prize for the creativity group of Robotacon (Robot Talents Contest) – an annual robot contest organized partly by nationwide education authorities.

The students, around 10, said the main reason for their design was that the area where they live has been increasingly affected by rubbish while materials and resources for production and consumption are limited.

They hope to help build a green, eco-friendly city with their idea of a waste treatment plant, which they presented in English.

Also showcased in the same contest category were other models describing satellite-based monitoring of the earth’s climate and garbage classification.

The Robotacon this time was for elementary and middle school students only, and divided into six groups: robot assembling, robot sumo wrestling, robot football, robot balloon puncturing, robot programming, and robot creativity.

The winning teams are expected to participate in an international robot contest in South Korea.
