This document describes the development of a smart robot to clean tennis courts. The system uses an Arduino or FEZ Mini microcontroller on the robot controlled by an Android application over Bluetooth. The robot is designed to collect tennis balls and clean court lines. The system architecture connects the Android client to the microcontroller server on the robot. Hardware implementations use the Arduino and FEZ Mini with motors, sensors and other components. The Android app allows selecting the microcontroller and controlling robot movement and functions. Prototypes of the tennis court cleaning robot were successfully realized.

19. CONCLUSION:
 Area of embedded robotics has been developing very fast and with appearance of a cheap
microcontrollers has become very popular for both programming and business.
 The Android is open-source platform and probably most popular mobile platform beside the
iOS.
 The Arduino is also open-source, with very low price for common user and very popular
for programming because of similarity with C programming language.
 Solutions presented in this paper show that is possible to develop a remote control system
with the combination of the Android and the other micro controller platforms.
 Because of that it is very important to follow development of physical computing and
robotics in the future.
