Design and Implementation of IoT Enabled Grass Cutting Robot Powered by Solar PV System

The conventional energy sources are diminishing, and researches try to make the most use of renewable energy sources. This proposed method was designed to have a solar-powered grass-cutting robot that can run by utilizing the solar energy as primary energy source and facilitates to avoid obstacles. The usage of electricity and fuel is avoided since solar energy is being used for the proposed system. The blade is coupled with DC motor to cut the grass and Battery Operated (BO) motor was utilized for controlling the directions of cutter. These motors and the energy from the solar panel are interfaced with the NodeMCU microcontroller. The directions of the robot's wheels and the On/Off process of the cutter is controlled by a mobile application which is called Remote XY. This mobile app is connected to the wi-fi network of the microcontroller. A robot is a system that executes specific tasks with little or no human intervention at high accuracy and precision. This proposed system is based on a working principle of a grass cutter robot, and it involves less human intervention and operates at high accuracy in the respective application. This grass cutter robot can be accessed in all directions with the help of the Internet of Things (IoT). IoT is used to connect and operate the robot through mobile applications.
