3. Problem Statement
Conventional grass cutting methods are time-consuming and require
constant human intervention. Maintaining large lawns or fields with
traditional mowing techniques is labor-intensive and may not be
practical for some situations. The need for sustainable and efficient
lawn maintenance solutions has become essential as society
increasingly embraces environmental consciousness and automation.
4. Objectives
Design a Solar Powered Automated Grass Cutter that can operate
independently to reduce human effort and intervention in lawn
maintenance.
Integrate obstacle detection and avoidance mechanisms to ensure
safe and efficient navigation across the lawn.
Implement a reliable and efficient cutting mechanism to ensure
uniform grass trimming and coverage.
Develop a solar charging system that harnesses renewable energy
to power the grass cutter, minimizing the environmental impact.
5. Introduction
The Solar Powered Automated Grass Cutter is a novel project that
leverages renewable energy and automation to revolutionize lawn
maintenance. By combining solar power with autonomous navigation
and grass cutting, we aim to provide an eco-friendly and efficient
alternative to traditional lawn mowing methods. This project aligns
with the growing focus on sustainable technologies and offers a
practical application of electronics engineering in the field of green
energy and automation.
