I have a robot that follows the owner around using ultrasonics.

The robot has 2 microphones (ultrasonic) one on each shoulder pointing
up and slightly forward.  The owner has a handheld ultrasonic
transmitter that transmits a continuous train of ultrasonic bursts.  The
robot turns off the drive motor that is on the side of the microphone
that has the highest output.  When both mics are balanced then the
course is correct and both motors are on.  Since the mics face somewhat
forward, the front to back error is compensated.
