Development of a Versatile Structure for Mounting Drone Audition-Purposed Measurement Equipment

Drone audition which is an audio-based searching technology is expected to be utilized for search and rescue op- erations in disaster areas. In this technology, the measurement equipment is required to be mounted on drones. The previous structure for mounting this equipment was designed for each drone and is costly to implement. In this paper, we propose a structure that can be universally installed on drones with a general shape. The structure was actually fabricated and confirmed its versatility by installing it on drones. Additionally the weight of the structure and measurement equipment was measured and verified its applicability by comparing the payload of a drone. We performed static load analysis and eigenvalue analysis of the structure using mechanical properties of 3D printed parts measured by three-point bending test. As a result, it was confirmed that the proposed structure has enough strength and suitable vibration characteristics to replace the previous structure.
