Getting started with Android and its ROS interface


There exists a cool interface between ROS and Android. As you know, Android is one of most popular operating systems in mobile devices. Just imagine: if we can access all features of a mobile devices on the ROS network, we can build robots using it, right? We can build Android apps with ROS capabilities and can make any kind of robot using it, its scope is unlimited.

The following shows how the communication between android device and ROS robot is happening. The figure shows an example Android-ROS application which can teleoperate robot from an android device. Each android application should inherit from RosActivity which is getting from Android-ROS interface, then only we can access ROS API's in our application. We can see more about the API's after this section.

The core backend of the Android ROS library is RosJava (http://wiki.ros.org/rosjava), which is an implementation of ROS in Java. There...
