Multi-sensory Olfactory Quadruped Robot for Odor Source Localization*

Abstract

With the rapid development of industrialization, hazardous chemical gas leakage accidents not only cause huge losses to people and economy, but also cause great damage to the environment. Research into how to efficiently, safely and accurately search for and locate sources of toxic, hazardous, explosive, flammable and other dangerous chemical gas leaks has become an urgent and realistic need. In this work, we focused on promoting the application scenarios of mobile robot-based odor source localization technology and proposed an olfactory quadruped robot capable of odor source localization tasks in complex environments. Compared to traditional wheeled robots, olfactory quadruped robot are more adaptive and eco-friendly. The robot is equipped with a variety of sensors and has a rich perception of complex environments, enabling it to complete complex tasks such as mapping, navigation and odor source localization in unstructured terrain.
