A lawnmower can be defined as a machine that uses revolving blades to cut grass surface to uniform height. Lawnmowers are primarily used for cutting uneven grass surface on sports grounds and extensive gardens. There are several types of grass cutting machine or lawnmowers presently in use. Our Project proposes easy and efficient method to cut grass using solar power. It is capable of detecting and avoiding obstacles also it functions without any human interaction. This project is equipped with a solar panel which is used to charge the battery, 12V rechargeable batteries are used. Microcontroller Arduino UNO is interfaced with ultrasonic sensor and is used to control the movement and motion of lawnmower. The arduino UNO is interfaced with motor driver IC and ultrasonic sensor for control and for detecting obstacles, this enables smooth operation of the lawnmower without any havoc. The motors of the revolving blades and the vehicle wheels are connected to the UNO board which controls working of all the motors. An Ultrasonic sensor is interfaced for object detection. The robotic lawnmower is programmed in embedded C language using Arduino IDE software in such a way that the microcontroller moves the vehicle motors in forward direction when no obstacle is detected, on detection of any obstacle the ultrasonic sensor senses and provide signal to the microcontroller, hence it stops rotation of cutter blades to avoid any damage to object/human/animal or whatever it is. The microcontroller then changes the direction of the robotic grass cutter until the object is out of its way and the grass cutter moves again in forward direction..
