1.1 Introduction
A fully automated solar grass cutter robot is an autonomous device designed to cut grass using solar power as its primary energy source. It operates independently with minimal human intervention, utilizing advanced sensors and control systems to navigate and perform lawn maintenance tasks (Ali et al., 2018). The increasing demand for sustainable and energy-efficient technologies has driven innovations across various fields, including robotics and landscaping. The concept of a Fully Automated Solar Grass Cutter Robot exemplifies this trend, combining advanced robotics with renewable energy solutions to address the challenges of traditional grass-cutting methods. The primary motivation behind developing such a robot is to create a more eco-friendly alternative to gas-powered or electrically driven lawn mowers, which often contribute to environmental pollution and require substantial human intervention.
This chapter will address the background information that motivated this study, the challenges that prompted it, its aim, and its objectives as a preface to subsequent sections of the study. Additional factors include the study's significance, scope, limitations, and the definition of technical terms.
1.2 Background of Study
The development of the Fully Automated Solar Grass Cutter Robot reflects a broader evolution in robotics and sustainable technology. The history of automated lawn care devices began in the 1960s with the advent of the first electrically powered lawn mowers, which marked a significant step away from manual cutting methods (Hoffmann, 2015). The concept of automation in grass cutting took a leap forward with the introduction of robotic lawn mowers in the late 1990s. These devices, such as the Robomow and Husqvarna Automower, utilized advanced sensors and control systems to autonomously navigate and cut grass (Haggard et al., 2009). Although these early models demonstrated the potential for reducing human labor, they were primarily powered by traditional batteries, which limited their operational efficiency and environmental benefits.
The integration of solar power into robotic systems began gaining traction in the early 2000s as advances in photovoltaic technology made solar panels more efficient and cost-effective (Gonzalez et al., 2016). Researchers and engineers began exploring how solar energy could be used to power various types of autonomous robots, including lawn mowers. This shift aimed to address the environmental concerns associated with battery-powered and gas-powered devices, offering a more sustainable solution for powering robotic systems.
Traditionally, grass cutting has been a labor-intensive task requiring substantial energy consumption and maintenance. Conventional lawn mowers, whether gas-powered or electrically driven, contribute to environmental issues such as greenhouse gas emissions and noise pollution (Feng et al., 2019).

Conventional lawn mowers, whether gas-powered or electrically driven, contribute to environmental issues such as greenhouse gas emissions and noise pollution (Feng et al., 2019).
The advancement of robotics has led to significant improvements in automation, with autonomous systems increasingly being utilized for tasks ranging from industrial manufacturing to domestic chores (Nguyen et al., 2020). The integration of solar power into these systems represents a progressive shift towards sustainable technology, offering a way to reduce reliance on fossil fuels and lower operational costs (Ali et al., 2018). Solar energy, being abundant and renewable, provides a viable solution for powering autonomous robots, particularly in applications where continuous or periodic operation is required. Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the construction process of fully automated solar grass cutter robot.
1.3 Statement of Problems
Investigation revealed that the development of a Fully Automated Solar Grass Cutter Robot presents several challenges and issues that need addressing. One significant problem is the efficiency and reliability of solar power in varying environmental conditions. Solar panels depend on consistent sunlight to charge the robot’s batteries effectively, which can be problematic in regions with limited sunlight or during cloudy periods (Gonzalez et al., 2016). This reliance on solar energy may limit the robot’s operational time and effectiveness, particularly in areas with irregular weather patterns.
Another issue is the cost associated with integrating advanced technologies into the robot. While solar panels have become more affordable, the overall expense of incorporating them into robotic systems remains high. This cost includes not only the solar panels themselves but also the additional engineering required to ensure that the robot operates efficiently and effectively under various conditions (Ali et al., 2018).
Furthermore, there is a challenge in balancing the robot’s size and power requirements with its energy source. Larger solar panels might improve energy capture but could also increase the robot’s size and weight, making it less maneuverable. Conversely, smaller panels may not provide sufficient power for extended operation, impacting the robot's ability to complete tasks efficiently (Feng et al., 2019). This balance is crucial for developing a practical and functional automated grass cutter.
