Design of smart and self-controlled Solar Grass Cutter with Lawn Coverage

Abstract

In this paper, we design a piece of equipment called the "Variable Head Automatic Solar Grass Cutter.” The system comprises basic components, including a motor drive circuit, control circuit, and solar panel. The overall operation is controlled by an Arduino microcontroller. The proposed system can automatically cut the lawn while adjusting the cutting height according to the surface needs, making it suitable for different types of lawns. The machine's cutting system consists of a DC motor, which drives and controls the rotating edge along a nylon cord, enabling the machine to cut grass with precision and speed. A primary concern of the machine's operation is the safety of the user. To avoid collisions, an ultrasonic sensor is installed on the front of the machine, allowing it to detect and avoid obstacles in its path. This project utilizes solar panels and rechargeable batteries, reducing energy consumption and promoting the use of renewable energy sources. This makes the machine eco-friendly and cost-effective. Consequently, this machine provides an opportunity to promote progress in innovation and maintenance.
