Solar Grass Cutter

This paper presents the development of an autonomous Solar Grass Cutter, incorporating both an ADXL accelerometer and ultrasonic sensors for enhanced navigation, safety, and efficiency. The system operates entirely on solar power, contributing to eco-friendly and sustainable lawn maintenance. The ADXL accelerometer is used for monitoring the mower's orientation and detecting tilting, while the ultrasonic sensors are employed for obstacle detection and distance measurement. These sensors enable the grass cutter to autonomously navigate around obstacles, avoid collisions, and ensure smooth operation across varying terrains. The integration of the ultrasonic sensors provides real-time data on the proximity of objects in the mower’s path, allowing it to adjust its movement accordingly and prevent damage. The microcontroller processes inputs from both the ADXL and ultrasonic sensors to control the mower’s motors and optimize energy usage. Additionally, the solar panel efficiently charges the system, ensuring continuous operation without the need for external power sources. Experimental results demonstrate that the system is capable of efficient lawn care with effective obstacle avoidance, precise path planning, and safe operation. This solar-powered, sensor-driven grass cutter offers a promising solution for environmentally conscious, autonomous landscaping.
