Help - Fuzzy Logic Book!

I am a final year honours Engineering student at the Australian
National University in Canberra Australia. My final year thesis is to
design a fuzzy logic controller for a robot that is used to navigate a
blind person through a series of obstacles. The robot is currently
implemented witht a PID controller and uses sonar sensors. At present it
just roams about a room with no specific goal. So my controller
initially will just require obstacle avoidance. Although I intend to
upgrade this to implement goal based movement if I have the time. At
present I am using fuzzy logic to convert the sonar echo pulse into some
kind of information about the obstacles.

Since I have had no experience in Fuzzy Logic I need a good reference
book to learn it from. Unfortunately our University libraries only
contain old books on fuzzy sets, numbers and theory. I find it hard to
relate this to my project and I was wondering if anyone could recommend
a book that covers the basics of fuzzy control and fuzzy logic. I would
prefer one with good examples rather than a purely mathematical one.

Also I am also having difficulty finding a good book on sonars used by
robots. Lots of books on Radar and acoustics but not many at our
library specifically that deal with sonars.

cheers and thanks in advance
