Fully Automated Solar Grass Cutter

ABSTRACT— The paper demonstrates an analysis of a solar-powered grass cutter system which combines renewable technologies with automated features and remote control to resolve operational expenses and environmental damage and reduce labor requirement when maintaining turf. The equipment collects solar power from a high-performance solar panel before the stored energy gets saved in a rechargeable lithium battery which drives the BLDC motor for accurate grass trimming. An L298N motor driver together with an HC-05 Bluetooth module controls the movement of four DC gear motors through smartphone applications to provide enhanced functionality and safety. The methodology executes three stages starting with component selection and ending with system testing and evaluation of power efficiency and operational reliability and cutting precision under different testing conditions. The performance evaluation of the system reveals its competency in precise trimming with low energy usage while remaining environmentally sustainable yet acknowledges restrictions from solar power dependency along with restrictive Bluetooth distance. The technology serves residential gardens while operating in public parks as well as sports fields and agricultural farms and will gain capabilities from AI-based navigation and GPS integration along with IoT connectivity for self-operation in the future. The project presents an efficient sustainable technological system which advances toward establishing smart green law maintenance practices.
