  • Faculty Supervisor: Arye Nehorai
  • Goal:
    • Determine the ability (accuracy and precision) of the current

sensors to measure concentration

      • Test on substance like ethanol that the sensors are designed for
      • If accuracy and precision are sufficient for source localization,

continue with these sensors, otherwise, we will have to find different sensors

      • Test whether acquisition time can be shortened for concentration measurement
      • Test whether performance improves with a different experimental

setup (e.g., using a fan to blow air across the sensor)

    • Incorporate digital resistors into the circuit design to allow

on-line optimal concentration estimation

    • Program a function in Matlab to estimate the direction to the

source from the concentration measurements of two sensor arrays

      • Test with simulations in Matlab
    • Incorporate the direction estimation into a guidance program for

the robotic platform

      • The robot should move to seek out the source of the odor
      • It should update its direction of movement periodically according to

new direction estimates
