Since the components are shipped with an unknown arrival date and for testing the interaction of the different sensors and actuators we will build an Arduino Lego Mindstorms setup on three wheels.
The NXT will therefor provide some basic navigation functions like goForwards, goBackwards, rotateRight, etc., as the software for basic flight is going to do later, too, and control the motors accordingly. The Arduino will be connected to the rest of existing components as usual.
The NXT block is generally able to communicate over I2C as master to any slave device, for instance the Arduino. Via simple looped polling the NXT can ask the Arduino for drive commands.
To connect the Lego block to the Arduino a Mindstorms NXT cable is ordered, which will be cut open and linked to the microcontroller. For wiring the LEGO MINDSTORMS NXT Hardware Developer Kit.pdf gives a good start. In addition the webpages of leJOS News and Dexter Industries seem to be quite helpful.
