Odor tracking in the turbulent flow environments
with lobster-inspired robots

Many animals locate sources of chemicals in their habitats at speeds  that exceed that which can be realized by reliance on passive diffusion to carry an odor from its source to their olfactory organs.  Thus allowance for -- or exploitation of -- the mass transport processes which are responsible chemical dispersal processes in natural environments must be part of the strategies of animals that exceed diffusion based speed estimates. Turbulence, a common attribute of fluid mechanical mass transport, has historically raised two limitations that have impeded progress in understanding how animals solve (or robots could solve) the chemical-tracking problem in natural or even laboratory environments. We have used BioMimetic robotics to approach the problem of chemical tracking in turbulence by constructing autonomous underwater robots that use the American lobster as a source of constraints.

In his talk Prof. Grasso  will describe this research and discuss its significance for understanding animal behavior and the development of biologically derived algorithms for BioMimetic robots.
