I'm looking for a wire guidance transmitter and sensor system (similar to an invisible dog fence) to control the route of a  robot lawnmower.  A transmitter puts a RF signal on the buried wire and sensors on the robot pick up the signal and follow it.  This type of equipment is used a lot in industry but industrial grade electronics is very expensive.  I am looking for a low-priced transmitter and sensors.  I have googled and found nothing.  Please don't suggest I paint a white line all over my lawn and use photo sensors.  A GPS system is only good for plus or minus 5 meters, I want plus or minus a few centimeters.  Any other suggestions?  Maybe I will buy a used invisible dog fence and open up the dog collar and see if I could get a signal from it.

Anyone know where I might buy hobby robot wire guidance controls?

Where'd you find the magnetometer for so cheap?  Any I've found are in the $20 range.

How do you think the beacons will affect battery life?  Assuming it takes too much power, would it make sense to mount one or more beacons on the charging base instead?
