I have developed an ultrasonic tracking system, called the UlTra System,
that tracks a lightweight, piezoelectric ultrasonic transmitter over a 100
ft x 100 ft area. I have both a 2-D and 3-D tracking version.
Unfortunately, the cost of this system is not cheap ($8,000 for the 2-D and
$12,000 for the 3-D). The system is used primarily in environmental
surveying, but could be used to track and control a robot in real time. I
mention it because of your interest in the problem.
