Inspection of Flyover Bridges Using Quadrotor

Abstract

Unmanned Aerial Vehicle (UAV) is a military product used extensively in the last decade. The successful outcome has expedited the migration of this technology to the civil market. Nowadays, UAVs can perform photogrammetry, inspection of civil buildings, delivering goods and assisting in rescue missions. The results depend on multiple factors, such as identification of flight mission, choice of UAV type and control algorithms. There are various types and sizes of UAV. The quadrotor is the one of most affordable and manoeuvrable system but it lacks stability. Therefore, we are discussing in this paper how to improve the stability of the quadrotor, while performing routine bridge inspections.
