  author={Andrew James Myrick and Thomas C. Baker},
  journal={Bioinspiration \& Biomimetics},
Here we demonstrate the feasibility of using an array of live insects to detect concentrated packets of odor and infer the location of an odor source (∼15 m away) using a backward Lagrangian dispersion model based on the Langevin equation. Bayesian inference allows uncertainty to be quantified, which is useful for robotic planning. The electroantennogram (EAG) is the biopotential developed between the tissue at the tip of an insect antenna and its base, which is due to the massed response of…

Comparing Insect-Inspired Chemical Plume Tracking Algorithms Using a Mobile Robot

Four chemical plume-tracking algorithms have been compared using a mobile robot and the simplest implemented algorithm, surge anemotaxis, was found to be the fastest, but the shape of the tracking paths observed indicated that this simple algorithm may not explain the plumes-tracking behavior of certain insects as well as the other algorithms tested.
