Robot Odor Localization: A Taxonomy and Survey

Abstract

Robotic odor localization has become a prominent research area in recent years. It promises many valuable practical applications, and contributes to the knowledge of biological odor localization, which has in many cases been the source of inspiration. There have been a diversity of approaches, implemented in both simulated and practical experiments, with a wide variety of platforms, and in a number of environments. This article presents a survey of the existing methods, which have been organized into taxonomic classifications. This provides a framework in which to evaluate the methods, view how they relate to each other, and make qualitative comparisons. The methods are grouped at the highest level by environmental conditions, and then by the localization method which in most cases is closely associated with the type of sensors used.

An inexpensive flying robot design for embodied robotics research

“…Ground robots have demonstrated steering, distance estimation, and obstacle avoidance [27][28]. They have also been used for olfactory-related tasks in order to detect, localize, and navigate toward odor cues [29]. Rugged, wheeled robots have been taken out of the lab and utilized outdoors to replicate the path integration and landmark steering of ants [28].…”

A distributed formation-based odor source localization algorithm - design, implementation, and wind tunnel evaluation

“…A survey of previous research in odor source localization and mapping can be found in [3], where a comprehensive taxonomy is defined and a multitude of solutions are discussed.…”

A Graph-Based Formation Algorithm for Odor Plume Tracing

“…Previous work in the field has resulted in a significant number of methods for odor tracking, of which a detailed survey is provided in [14]. Many algorithms take inspiration from living creatures, such as bacteria [4] or silkworm moths [20], and generally operate by switching a single robot among a set of simple behaviors.…”
