Cutting lawns at our leaving area is one of the important aspects, the lawns are cutted by human might involve risk. This project focuses on the development of a smart lawn mower robot to cut the lawns. The robot needs to satisfy certain criteria that are, portable, standard size, Bluetooth control system and can cut the lawns as defined area. The energy that we used for the robot is battery based is DC supply. It also a robot that can reduce pollution instead of using gasoline/petrol based lawn mower. The aim of this report is to design and implement a smart lawn robot. The function of smart lawn mower robot is to cut the lawn process become easier than cutting the lawns manually. This robot is control by Bluetooth module and send output to an Arduino. Next, this robot is used Arduino UNO to operate and the function of Arduino is control the movement of robot. Then 3 to 4 DC motors is needed to connect with the Arduino and motor driver.In additional, the function of motor driver is to take a low-current control signal and turn it into higher-current signal that can drive a motor. After that, the DC motors is connect to two 15V battery as power supply. Moreover, the advantage of using robot will saves our environment instead of using gasoline or patrol based energy and also will help people who suffer cutting the lawn under the hot weather.
