Gas Source Localization Using an Olfactory Mobile Robot Equipped With Wind Direction Sensor

摘要

Searching for locations of dangerous, explosive, and flammable gas sources by human can endanger health and even lives. Therefore, the use of robots is needed in this situation. This paper discusses the gas source localization using an olfactory mobile robot equipped with two gas sensors to navigate the robot and three anemometers to determine wind direction. The Intel Curie module is used as a microcontroller that handles all electronic compartments to obtain sensor signals, and robot movements. The experimental results show that the addition of a wind direction sensor can improve the robot's ability to find a gas source, in which the robot does not lose track of the odor plume in a turbulent air.
