Hi,
just passing by coming from sci.geo.satellite-nav it occured to me that even
under best circumstances and assuming the robot to be on a plane area two
microphones will not provide the position, or better said, it still might be
on either one or the other of the maximum two intersections of two circles.

Betreff: Navigation by sound?

Hi,

has anybody tried a setup like this:

- The tower sends a message to the RCX.
- The RCX beeps.
- The beep sound is captured by two microphones on two neighbouring corners
  of the navigation space.
- Their signal is fed into a stereo soundcard.
- The computer finds the begin of the signals, computes the delays
  and from them the position.
- The computer sends the position to the RCX.
- Repeat.

Jürgen
