Abstract

The creation of an ecologically friendly and energy-efficient grass-cutting robot is the primary objective of this project. It will be an intelligent and user-friendly gadget that runs on solar energy and makes use of cutting-edge IoT technology and mobile application control. The first objective of the project is to design a grass cutter that reduces energy consumption by using solar panels, thus minimizing reliance on conventional electricity sources. This not only lowers operational costs but also contributes to environmental conservation efforts by reducing the carbon footprint. Next objective focuses on enhancing user convenience and control. By using the NodeMCU ESP32 microcontroller and the Blynk application, the grass cutter robot can be easily monitored and operated remotely via a mobile device. This feature is particularly beneficial for users with physical impairments and elderly individuals, offering them a seamless and effortless gardening experience. Lastly, the project aims to deliver a smart grass cutter that operates without producing air pollutants, ensuring a cleaner and healthier environment. In conclusion, this project presents a new approach to lawn care by combining solar energy utilization, IoT technology, and user-centric design to create an efficient, eco-friendly, and accessible grass-cutting robot.
