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.

This month's Circuit Cellar has an article on a Robot Boat that navigates
using digital compass and GPS to navigate through waypoints.

Adding an ultrasonic sensor would be an interesting setup.

Hello

I have another idea for a mapping robot that maps out a room and it's
obstacles.
This time I think that I could use an ultrasonic sensor to map obstacles
out to a distance, then have the RCX figure out the maximum distance
that can be moved forward without hitting anything. After this, the
obstacle mapping continues, and the clear path searching finds a new
mapping line. Then the map is uploaded to a computer, and plotted. This
map could be used to plot waypoints in the room for the robot to follow
to do a task.

    Now I want to know, Is this feasible? I think the only hard part
would be changing the array so that the new mapped values match in
positito with the old ones. Any ideas on this?

Andy
