This information dates back to where it was used on Turtlebot 1 and PR2 in fuerte, groovy and experimental hydro. Aot of it is still useful, but also much outdated now - particularly the android sections. If you'd like to update to doing things on hydro, especially for Turtlebot 2, start at the rosjava and android pages as well as the rocon_app_platform.
If you are looking to interact with a robot using android, install the Android Client. See below for detailed documentation.
