We have realized a binaural sensor for continuous sound localization with a
PIC16F88 that can be connected to many robot types. Precision : 10° in azimuth.
The sensor -called in the article "Stereo robot ears"- can be found in the new
edition of the journal ELEKTOR, which appears in 4 languages (German, French,
Dutch and of course English). Btw. the whole issue is dedicated to robots with
about 100 projects.
