Robotic Microphone Array for Locating Acoustic Sources |
| Comments |
In this project, we build a robotic microphone array with autonomous control of the array geometry for improving the localization performance of an acoustic source in 2D space. In our previous research projects on "Acoustic source location using cross-correlation algorithms" [1] (see also [2] and [3]), we found that the performance of the 2D position estimation algorithms using two pairs of microphones depends on array variables such as the distances between the individual and pairs of microphones, and also the sampling frequency. Hence, we wish to build a robotic system that will automatically control these variables for optimal performance.
In particular, this project will consist of the following stages:
1.- Build a robot based on Lego-Mindstorms which can be controlled from a computer. This includes designing a robot capable of moving the microphones and creating a software interface which allows to the real-time communication between the PC and the Lego-Mindstorm microcontroller.
2.- Design control algorithms that modifies the geometry of the array automatically given a performance criterion for acoustic source location.
