3D Distributed Odor Localization and Mapping

Odor Distribution Mapping (ODM) consists in creating a map of an odor distribution to identify where and how the odor is dispersed in a given area. This technique has applications when situations like gas leaks, environmental emergencies and toxic chemical dispersion occur. Enabling robots to perform this task would provide a powerful tool to prevent dangerous situations and assist humans when emergencies arise.

This project focuses on the integration of quadcopters in ODM with the ultimate goal of producing a 3D map of a gaseous plume in an environment. Prior to this work, simulations and real time experiments focused on odor distribution mapping and localization exploiting mainly ground robots. Including quadcopters in these experimental settings is an important step to explore 3D mapping and localization algorithms and move towards experiments that are closer to real world scenarios.
