I was wondering whether anyone has come up with something so that you can
accurately position your robot in a room. I was thinking about a system
involving 3 speakers and a tone generator, and a mike. You create a
circuit that waits for a sound to trigger and then triggers each speaker
to generate a fixed frequency pulse of say .1 second duration in sequence,
by measuring the volume using one of the A/D convertors on the RCX, it
should be possible to triangulate your position. If anyone has any ideas,
I'd love to hear them.

| (...) One possibility is to use inertial navigation. It's not cheap (relative to the cost of the RCX), but you can get 3-axis accelerometers for less than $200, e.g. (URL) respect to your idea of using tone generators to triangulate position: It has (...)
