Hi Kate,
I just want to know how/where to get a sonar transmitter/reciever pair with
different frequencies for robot positioning.

Can sonar module from Polaroid do that?

Thanks,
William



If you wanted to be more advanced and definitely return to the base, you
could also make sonar beacons for positioning (at different frequencies so
it doesn't get confused), and tell the return behaviour that home is, say,
beacon one distance x, beacon two distance y, beacon three distance z, and
to go there (by, perhaps, finding beacon distance one, followint it to
beacon distance two, and if that doesn't have beacon distance z, continue • on
until you hit beacon distance two and three).

William - For my group project, we bought sonar transducers and built circuits for them. Our original recieving circuit is digital rather than analog as we were only going to have one. The circuits we used are on our group's website on our (...) (24 years ago, 12-Jul-00, to lugnet.robotics.handyboard)

If you want to return to "base," all you need is a beacon of some sort. For example, you could use CdS cells (or anything that finds EM in the visible light/low IR range) and a lightbulb (or series of lightbulbs, like a strand of Christms tree (...)
