Path Planning and Control of a UAV Fleet in Bridge Management Systems

Traditional methodologies for precise inspection of bridges (pavement, beams, column cap, column, joints and inside box girder, etc.) with By-bridge equipment, Aerial Work Platform (AWP) or via ropes have several limits that can be overcome by using Unmanned Vehicles (UAVs). The constant development in this field allows us to go beyond the manual control use a single UAV. In context rules, research provides new inputs multilevel approach used today methods structural drones. Today, UAV-based inspections are limited and/or semi-automatic many restrictions on trajectory settings, especially areas difficult access Global Navigation Satellite Systems (GNSS) denied still require intervention human operator. This work proposes autonomous navigation fleet UAVs infrastructural inspections. Starting from digital twin, solution is provided problems such as definition set reference trajectories design position controller. A workflow integrate generic Bridge Management System (BMS) type provided.
