Thai students make solar lawn mowers

Remote control lawn mower operated by solar energy, can cut all grasses, including soft grass.

Three students from the Agricultural Engineering Faculty of Thailand's RMUTT University of Technology, Anyika Sawangjitr, Pannaphat Surachawaja and Thanayut Nethibaht have successfully designed an energy-controlled remote-controlled lawn mower. Sun. The machine has a high level of safety because the machine cover is designed to remove the grass that has been cut back. Compact, easy to operate.

According to Anyika Sawangjitr, the use of hand-held lawn mowers or lawn mowers must work in a standing position that requires centrifugal force to greatly affect health. In addition, in addition to the high-cost lawn mower, it is also necessary to consider the safety factor, durable working time and easy maintenance for the machine. Therefore, the study has been conducted very carefully to be able to produce a remote control lawn mower to improve the quality of life for farmers.

This remote controlled solar lawn mower has a simple look.

It can cut all grasses, including soft grass. The front wheel of the machine is a free-wheel remote control with a frequency of 2.40 - 2.48 GHz, receiving energy through solar cells stored in the battery. Two DC motors, one designed at the cutting blade and the other in the Arduino control panel, control the rotating wheel. Although it has such a refined operating mechanism, it looks extremely simple on the outside because the entire structure is covered by a solar panel.

The machine is controlled by remote with a distance of 80-100m, can move forward, backward or turn left, turn right with three speeds and can rotate in small areas. When operating outdoors, the device will simultaneously be energized and stored into the battery.

Solar panels are placed on the machine at a 13 ° angle so that the most optimal solar energy can be obtained at all times. The device can operate continuously for 2 to 3 hours per day.

RMUTT University of Technology (Rajamangala University of Technology Thanyaburi, Thailand) is a young university that was only established in 2005. Currently, the school includes a lot of departments from science and technology to agricultural engineering. industry, architecture, business administration, both traditional and musical music .
