Start with this simulation model of the 4 microphones. Extract to your Home Directory and run MicSourceLocator.vi. This can be the starting point for your application.
- Source Localization
  - Compute angle of arrival for each pair
  - Compute source location by computing the intersection of the 2 lines given (x,y,theta) of each pair
  - Compute all possible intersections (Web)
- Bandpass signal on all channels
- Spectrogram
- Store previous buffer and do level detection to handly an Asynchronous Source
Test with microphone array microphone array. Connect the line out from the PC to a speaker and generate a chirp on the sound card using Chirp2SoundCard.vi.
- In the DAQ Assistant, make sure the Analog Inputs are from the USB-6210, differential, +/- 1 V
- To test with "Real Simulated Data", use these waveforms to troubleshoot.

Projects for smaller groups:

Compute angle of arrival on Robot platform
PC to Robot communication using Shared Variable
Robot position control (x,y,theta)
Main PC Controller to compute source location from 5 robots
- Manual Position
- Automated controller
Robot/FPGA implementation of Cross Correlation
Thin client communication to Robot
