The rapid development of technology, especially in the field of robot development that makes quality of human life is higher. Robots were developed not to facilitate human work. Many tools are made to make their work easier and faster. In the robot world there is a mobile robot category. Mobile robots are robots that can move places and be controlled automatically or manually. By utilizing technology using Arduino and Android it can realization become realControl robot with Bluetooth transmission media can happen with existence of support application on smartphone through android. For that it was made “ Automatic Lawn Mower using Bluetooth via Android Smartphone’’. The program for author robots is created in an Arduino software, which commands that will be inserted into the UNO microcontroller chip as the brain of the robot. For mobile robot drivers using dc gearboxes placed the rear position of mobile robot, while for user interface, we use Arduino Bluetooth controller software for robot control applications. Communication between wheeled robots using Bluetooth communication media through smart phones.
