Hi, I am putting together a small robot to compete in a "Sumo" style
competition in a few months, I have my basic algorithym worked out and have
tested it on a bread board with a 16c55 and LED's, but I am wondering what
would be the best way to detect my opponent, the competition ring is about 5
foot diameter, I am thinking using photo-transistors, I wouldn't need to
have a longer detection range than say 2 feet, anyway if someone has a web
page or knows of where I could find some good information I'd appreciate it.

I'd also like to share some of this information if you get any
response.

I can remember that somebody made a PIC program called "sona-pic"
designed to control a Polaroid ultrasonic module. As far as I can
remember it has a range of several feet.

Hi are you going with an agressive or defensive posture and if you're
willing to divulge any other details (I understand you're in
competition) I for one would be interested? Earlier articles I chanced
upon fueled many daydreams.I particullarly liked the inverted dish that
sucked itself to the floor :) Tony M.

Hi I was involved in a simmilar project about 10 years ago. I used a
ultrasonic transducer pair mounted on a stepper motor to give me a 360
Deg viewing circle. The system worked great.

Cheers Peter .........
