Acoustic Navigation for Mobile Robots
Project Type: Sensor System Design, Mobile Robot Control
Advisors: Ricardo Gutierrez-Osuna, Steve Ortiz
Project Description:
The goal of this project is to develop a microphone array module
that will allow a mobile robot to detect acoustic beacons in its
surroundings. The array will consist of miniature microphones in a
ring configuration to provide 360 degree sound localization. This will
allow the robot to display a number of phonotaxis behaviors,
e.g. homing in or fleeing from acoustic sources.
Major Goals:
- Develop an printed circuit board (PCB) interface for the microphone array
- Develop acoustic fixtures to improve the directionality of the individual microphones
- Develop algorithms to estimate the angular position of acoustic beacons
Deliverables:
- A PCB-mounted microphone array for miniature robots
- Schematic diagrams, parts list and instructions to assemble the system
- Project documentation, as described in the course syllabus
- Live demonstration
