A novel bio-controller for localizing pollution sources in a medium peclet environment

Nature inspired solutions enable biological systems to adapt and accomplish their tasks in very noisy and uncertain environments. Taking inspiration from nature, a novel bacteria controller capable of finding the source of pollution in an underwater medium turbulent environment is presented in this paper. Experiments prove that the controller is capable of performing pollution source exploration, pollution plume transverse and source declaration in a medium Peclet environment without distinctively separating these three components as most researchers did. The results obtained from these experiments are considered as a step towards the deployment of robotic fish in a highly turbulent marine environment. Finally, a brief conclusion and future extension are presented. © 2010 Jilin University.
