Hi,
Is it possible to reprogram a wireless transmitter to enable a motorized wireless receiver find the signal and independently maneuver it's way to the source?(the transmitter)

You would possibly use a subaudible tone to go with it. So the receiver could track and locate correct transmitter. It could use maybe an Adcock type antenna. Problem is It would go as the Bird Flies. You still need other sensors and optics to avoid hitting physical objects in the way.
