The Roboear (Robot Ear) is designed to find the direction to nearby sound sources. In audiology this is called 'localization'. Humans can usually localize a sound to +- 10 degrees. The Roboear's three microphone array can usually localize a sound to a 30 degree sector. It uses amplitude comparison and acoustic cross-correlation to localize sounds. The Roboear's internal processing is done on a PIC 8-bit microcontroller. The Roboear can also function as an audio acquisition front-end for more powerful computers. Communication with the host computer is jumper selectable as either UART, or SPI. Complete documentation can be found in the user's manual on the Data & Documentation page.
The Roboear kit or bare printed circuit board are available from SERVO Magazine (T&L Publications) web store.
The current firmware version is 1.10.
