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.

Subject: Ultrasonic Mapping Robot
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

| 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 (...) (25 years ago, 24-Apr-00, to lugnet.robotics)
