Polaroid Sonar

[Eelco]

Hello everybody,
For a school project, I'm building a robot, wich must be able to
detect obstacles. For that purpose, I've arranged 5 polaroid camera's
with sonar ranging modules inside it. There are a lot of tutorials at
the internet, describing how to use the sonar. The only problem is,
that the modules used for the tutorials aren't the same as the ones I
have. I have got the Polaroid SX-70 version 2 camera's. This one has
got other connectors as the usual ones.
Instead of the 16 pin connector, it has got a 9 pin connector.
There are also about 6 wires, used for driving the motors etc. to
focus the camera.
There are some other possible connections wich aren't used.

I've made pictures of the module, and I hope somebody can tell me how
to connect it to my digital interface (to the computer).
You can download them from http://www.evenchillen.com/sonar/

I hope someone can help me, because the project has to be finished in
a couple of weeks, and I can't find a way out…

Thank you in advance!

Greetings,
Eelco van de Wiel

You should buy the polaroid sensor modules instead of complete cameras.
These have a convenient serial interface to give you the range data.
They also come with complete specifications.

Gee, I wish I had that much money for projects when I was in school!

Well, that's the problem: the regular sonar boards are much to
expensive. They are about 50 dollars each, and the camera's where for
free.
