Aim of this project is to evaluate the benefits arising from the application of Unmanned Aerial Vehicles (UAVs) in steelworks. So far UAVs have been deployed for military applications or used in small but growing number of civil applications, but never systematically in the steel industry. The goal is to substitute men in complex and expensive operations as those related to the monitoring, maintenance and safety of steel plant infrastructures. The implementation of real use cases with autonomous flight in two steel plant (TKSE Duisburg, ILVA Taranto) and the experimental feasibility for indoor applications will prove the benefits deriving from UAV technology.
