Remote control robot using Android mobile device

The paper describes the design and realization of the mobile application for the Android operating system which is focused on manual control of mobile robot using wireless Bluetooth technology. The application allows the robot control interaction with the display, or voice. When we use a graphical interface, we can monitor the current distance of the robot from obstacles. The measurement of distance is carried out by ultrasonic sensor placed in front of the robot. It was necessary to build a prototype of a mobile robot for the development of the application. The prototype of the mobile robot is based on the differential gear.
