+Robot control module
+--------------------
+
+### Abstract ###
+
+NxtAR is a generic software architecture for the development of Augmented Reality games
+and applications centered around mobile robot control. This is a reference implementation
+with support for [LEGO Mindstorms NXT][1] mobile robots.
+
+### Module description ###
+
+The robot control module is a control application that receives control commands sent from the 
+[NxtAR-cam][2] module and executes concrete control instructions as supported by the [LejOS][3] firmware.
+
+### Module installation and usage. ###
+
+Upload the NxtAR-bot_XXXXXX.nxj file to the LEGO Mindstorms NXT robot and execute it. Then follow the
+on-screen instructions. More detailed usage instructions can be found in the [NxtAR Android backend module][4]
+documentation. The robot must have the LejOS firmware installed prior to loading the nxj file.
