PC Implementation - Work in groups of 2

  • 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.

Robot Implementation - Work in groups of 2

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

System Integration - Everybody

  • Get all of the individual pieces to work together on all 5 robots
