If the chirp arrives at the same time at each mike, the robot is on the
right path, If one is delayed, the robot eases into the that direction

If one of  the chirps has been reflected from a distant hard surface the
long delay could interfere with the next pulse.  Something like that
happened to an early-warning radar sytem when the moon rose and
reflected long-delayed pulses.

A slow pulse rate or a variable one would overcome this.
