Invented 'Multi-purpose Robot for agriculture'

Nguyen Van Hoa, a student of grade 12A3, Hiep Hoa high school No. 2 (Bac Giang province) has successfully created "Multi-purpose Robot for agriculture" with the main functions of spraying pesticides and irrigation. trees and fruit picking.

With this product, I won the special prize of the 6th National Youth Bar, Youth and Children Creative Contest in 2010 and was awarded the Silver Medal at the International Exhibition of Youth Science and Technology in 2010. .

Born and raised in a family specializing in agriculture, Hoa understood the difficulties and struggles of farmers in planting, tending and harvesting rice and crops. Therefore, I had the idea to create an item that made use of household waste and learning to help farmers produce more convenient, reduce effort, and reduce environmental pollution. school and reduce substances harmful to farmers' health .

This robot product designed by Hoa has the most important function of spraying pesticides, in addition to the function of watering, with robotic arms for grasping, gathering and other sub-functions as " transformation ". to become a toy (four-wheel, humanoid .) for children.

The left arm of the robot is designed according to the remote spraying mode (up to 4m), suitable for spraying rice fields of about 8x8m in size.

The right arm is designed in the near spray mode, suitable for spraying water, pesticides for beds in the field. Robots are made mainly from pieces of pressed wood, thin zinc, aluminum frames, pulley wheels, shoelaces, iron chains .

In order for the robot to move, Hoa has designed a crawler system and a round wheel system, in which the crawler system utilizes the orange chains of the old motorbikes, while the round wheel system uses push-in wheels. some baby strollers.

In addition, the motor for the robot to operate is also taken from the old, damaged disc players. Behind the robot is designed to mount pesticide containers and water containers, with two pipes for spraying with a diameter of about 8cm each, in which a tube about 1m high and a tube about 60cm high.

The control panel system of the robot is self-researched, controlled by computer mouse and uses battery battery of type 12V and 7.2V. For robots to spray pesticides and water, it is necessary to install a mini compressor.

With such useful features, Nguyen Van Hoa's " Multi-purpose Robot for Agriculture " has been tested to work well in Hiep Hoa district's field.
