INTRODUCTION
Grass cutting is an essential maintenance activity in various environments such as residential lawns, agricultural
lands, public parks, and institutional campuses. Traditionally, this task is carried out using manual tools or fuel-
powered machines, which require continuous human effort and supervision. These conventional systems are not
only labor-Intensive but also inefficient for large-scale operations. In addition, petrol-based lawn mowers
contribute to environmental pollution through emissions and noise, while electric systems are limited by power
availability and cable constraints. As a result, there is a growing need for advanced solutions that can improve
efficiency, reduce human involvement, and minimize environmental impact.
With the rapid development of embedded systems, robotics, and Internet of Things (IoT) technologies,
automation has become a key solution for modern-day challenges. Smart robotic systems are capable of
performing repetitive tasks with greater accuracy and consistency compared to manual methods. These systems
can be designed to operate autonomously or semi-autonomously, reducing the dependency on human labour.
Furthermore, the integration of IoT enables real-time monitoring and remote control, allowing users to operate

systems from a distance and receive instant feedback on system performance. This enhances convenience, safety,
and operational efficiency.
Another important aspect of modern automation is the use of renewable energy sources. Solar energy, in
particular, has gained significant attention due to its availability, sustainability, and cost-effectiveness. By
integrating solar panels with energy storage systems, it is possible to develop self-sustaining robotic systems that
can operate without relying on conventional power sources. However, efficient utilization of solar energy
requires proper power management techniques. The implementation of Maximum Power Point Tracking (MPPT)
algorithms ensures optimal energy extraction from solar panels, thereby improving battery charging efficiency
and overall system performance.
The proposed system focuses on the development of a GPS-guided solar-powered smart grass cutter robot
integrated with IoT-based monitoring and live video streaming. The system is built around the ESP32
microcontroller, which offers high processing capability along with built-in Wi-Fi communication. This enables
seamless connectivity between the robot and the user through a web-based interface. The robot is equipped with
ultrasonic sensors that continuously monitor the surroundings and detect obstacles in real time. This ensures safe
navigation by allowing the system to stop or change direction when an obstacle is detected.
In addition to obstacle detection, the system incorporates a Global Positioning System (GPS) module to provide
accurate location tracking. This feature is particularly useful for covering large areas, as it allows users to monitor
the position of the robot and plan efficient movement paths. The integration of an ESP32-CAM module further
enhances the system by enabling live video streaming. This allows users to visually monitor the environment
and ensure proper operation of the robot, even from remote locations.
The combination of IoT, renewable energy, and intelligent sensing technologies makes the proposed system a
comprehensive solution for automated lawn maintenance. It not only reduces manual effort but also improves
safety, efficiency, and environmental sustainability. The system is capable of operating continuously with
minimal human intervention, making it suitable for real-world applications such as smart agriculture,
landscaping, and urban green space management.
Moreover, the proposed system addresses several limitations of existing grass-cutting methods by integrating
multiple advanced features into a single platform. It provides real-time monitoring, remote control, obstacle
avoidance, and energy-efficient operation. These features make the system more reliable and adaptable to
different environments. As technology continues to evolve, such smart systems are expected to play a crucial
role in the development of intelligent and sustainable solutions for everyday tasks.
