Abstract: The use of renewable energy resources has been increasing day by day, such as solar power. It leads to a growing interest in developing new systems which make use of it. One such system is the fully automated solar grass cutter, it uses solar energy to power itself and store solar energy in a battery in the form of electrical energy.It can also be controlled remotely by using the internet of things (IoT) or controlled automatically when connected to a power supply. The overall system efficiency is 94.37% and the existing model has 54% efficiency. This projectuses several components such as the Arduino Uno, Node MCU, ultrasonic sensor, motor drivers, solar plates, and DC motors. The IOT mode uses the ThingSpeak cloud application. Thisdevice is designed to automatically detect the obstacle and cut grass in a lawn while being powered by solar energy.The maximum efficiency during clear weather, of the charge controller is98% at maximum solar voltage, while the maximum efficiency of charge control during cloudy weather conditions is about 70%.
