Solar Powered Lawn Mower Robot

Abstract

The Solar Powered Lawn Mower Robot is a grass cutting robotic vehicle powered by solar energy. Operated by RF remote. The system uses 12V battery to power the vehicle movement motors as well as the grass cutter motor. We can charge the battery either solar energy or by electric power, we have given both options to charge battery. The grass cutter and vehicle motors are interfaced to an ATmega328 microcontroller that controls the working of all the motors. It is also interfaced to 433MHz RF receiver module for receiving signals from remote. The microcontroller moves the vehicle motors in forward, reverse, left and right direction with the help of RF remote. A lawn mower/ Grass cutting machine is a machine that uses a revolving blade or blades to cut a lawn grass. Lawn mowers employing a blade that rotates about a vertical axis are known as rotary mowers, while those employing a blade assembly that rotates about a horizontal axis are known as cylinder or reel mowers.
