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 serial UART, or SPI. Complete documentation can be found in the user's manual which is available for download on the Data & Documentation page.
WHAT ELSE DO I NEED?
The ROBOEAR-PCB-KIT includes all the components needed to build the ROBOEAR circuit board. The only thing you will need to supply is wire to connect the microphones to the circuit board. The items listed listed below are optional.
