I would add another question to Steve's valuable list.
Do you really want to do tracking? With one or two degrees of freedom,
ie; azimuth or azimuth and elevation.
IF that's what you're trying to do, then your sonar/radar sensor is going to
have to return enough information to know if the object is off center of the
tracking device "beam" and which way. You may find your RCX running out of
input ports quite quickly ...
And I, for one, will be really interested to know how you succeed in
obtaining this off center information :)
