 # An Android/Linux ground controller in Scala
 
-This project began with the goal of having an Arduplane follow a hang-glider and take pictures.  That work still continues (see the posixpilot subproject).  However, it quickly became apparant that much of this software could be used to make an Android based Ground Controller.

 A prebuilt version of the Android application is [on the Play store](https://play.google.com/store/apps/details?id=com.geeksville.andropilot).  If you are not interested in coding, you probably want to go there.
