The Robot Operating System (ROS) is one of the world-wide used framework in robotics, especially in the research field. This application gives you the possibility to start playing and learning this framework.

You can download the source code of both the phone and pc-side applications from http://www.gctronic.com/doc/index.php/Android_software#ROS; where you can also find more useful information on how to configure the system.
