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.
