Fully Automated Solar Grass Cutter

📋 Overview

The Fully Automated Solar Grass Cutter is a project designed to create a self-sufficient, energy-efficient grass cutting system powered by solar energy. This project integrates solar panels, a microcontroller, and a cutting mechanism to autonomously mow lawns without the need for manual intervention. It utilizes sensors to navigate the environment, detect obstacles, and ensure that the grass is cut effectively.

🚀 Features

• 🌞 Solar Powered: The system runs entirely on solar energy, making it eco-friendly and energy-efficient.
• 🤖 Autonomous Operation: The cutter moves automatically across the lawn, cutting the grass without human input.
• 🚧 Obstacle Detection: Sensors are used to detect obstacles in the path, ensuring the cutter avoids collisions.
• ⚙️ Efficient Cutting Mechanism: A sharp blade is controlled to ensure clean and efficient grass cutting.
• 🔋 Charging Station: A solar panel and battery system provide power to the cutter, ensuring continuous operation without manual recharging.
• 🔧 Low Maintenance: The system is designed to be low maintenance, requiring minimal human interaction once installed.

🛠️ Components Used

• Microcontroller: Arduino (or any other suitable microcontroller) to control the operations.
• Solar Panel: To charge the battery and provide power to the system.
• Battery: To store energy from the solar panel.
• DC Motor: Powers the cutting blade.
• IR Sensors: Used for obstacle detection.
• Motor Driver: To control the motors for the movement of the cutter.
• Cutting Blade: A sharp blade for cutting the grass.
• Wheels: To help the cutter move autonomously.
• Buzzer: To indicate completion or any malfunction.
• H-Bridge Circuit: To control the direction and speed of the motors.

🧠 Working Principle

1. Power Supply: The solar panel charges the battery throughout the day, ensuring the system has enough power to operate.
2. Movement Control: The Arduino microcontroller receives input from the sensors and controls the direction and speed of the wheels using the motor driver.
3. Obstacle Detection: IR sensors are placed around the cutter to detect any obstacles (like trees, rocks, or furniture) and prevent collisions.
4. Grass Cutting: The DC motor powers the cutting blade, which rotates to cut the grass as the cutter moves across the lawn.
5. Autonomous Navigation: The cutter moves in a random or pre-defined pattern, cutting the grass in all areas of the lawn.
