Gas Leak Detection in Collapsed Buildings Using Multiple Micro-drones

Abstract

This paper discusses a method for detecting gas leaks in collapsed buildings in disaster areas using multiple micro-drones. In this paper, we develop our own drone with a mass of less than 100 g equipped with a gas sensor and conduct gas detection experiments in an experimental environment. Computational Fluid Dynamics (CFD) is also used to visualize the air flow around multiple micro-drones. The results of the experiments and numerical simulations will show that leaking gases can be detected using gas sensors mounted on the drones by actively rolling up the gases with the propellers of the drones.
