Personal lawns, public parks, and gardens are major recreational spaces but require significant maintenance to remain operational. The primary maintenance tasks are grass cutting and weed removal, which demand substantial time and effort. Traditional lawn mowers and motorized cutters require human operation and rely on either fuel or electric charging, incurring ongoing costs and effort.

To address these challenges, we propose an automated robotic grass cutter that can autonomously maintain lawns and gardens. This robot eliminates the need for human intervention and is powered by solar energy, thus avoiding the recurring costs associated with fuel or electric charging.

Benefits of the Solar Grass Cutter Robot:

1. Efficient grass cutting with a high-powered motor.
2. Adjustable head to set the grass cutting height.
3. Durable body, wheels, and drive motors for off-road navigation.
4. Autonomous operation with obstacle avoidance using ultrasonic sensors.
5. Motorized drive using DC motors.
6. Solar-powered for self-charging.

The robotic vehicle features a set of geared motors with wheels, a metal robotic frame, ultrasonic sensors, controller circuitry, a battery, and a solar panel. The control circuitry and ultrasonic sensors facilitate easy navigation through gardens and lawns. The vehicle is equipped with four geared motors to provide the necessary torque for movement, and four large rubber wheels to prevent getting stuck in grass and weeds.

The body is constructed from a mild steel chassis with four drive motors mounted below. A central hole in the frame accommodates the grass cutter motor. This high-torque, high-speed motor drives the cutting tool attached to its shaft, enabling efficient grass cutting. The cutter motor mount allows users to adjust the cutting height by loosening a screw, thereby setting the desired grass length.

All motors are powered by a battery that is automatically charged via a solar panel mounted on the robotic frame. This setup creates a smart, automated, and eco-friendly solar-powered grass cutter system.
