The inspection of bridges [7], viaducts [8], and other civil infrastructures [9] using aerial robots requires the integration of specific sensors and devices, as well as the implementation of perception and navigation methods to conduct the operations in flight with a sufficient level of autonomy and positioning accuracy. The authors in [7] propose the deployment of a team of cooperative aerial robots to install inspection devices on bridges by spraying a resin onto the surface and applying a pushing force to keep the device attached. The paper presents the design of the control framework, covering the attitude/position and impedance controllers, the path planning, and the detection and estimation of the marked point. Two different aerial robotic solutions are presented in [8] for the visual and contact inspection of viaducts, where GNSS (Global Navigation Satellite System) positioning is not possible, requiring the integration of 3D LiDAR (Light Detectionand Ranging) combined with robotic stations to generate accurate maps of the environment. The presented work illustrates the development and integration efforts to increase the TRL (Technology Readiness Level) of aerial robots applied in real inspection scenarios. Specific methods based on vibration monitoring for the assessment of civil infrastructure using aerial robots equipped with deployable sensor units are described in [9]. Different sensor technologies for Structural Health Monitoring (SHM) are identified, presenting the design of a sensor unit based on an accelerometer with a docking mechanism that can be attached to metallic structures using the aerial platform. Damages on monitored structures are detected as changes in their Dynamic Signature Response (DSR), relying on the B-Spline Impulsive Response Function (BIRF) for representing the time-variable system dynamics. The paper illustrates, in laboratory conditions, the deployment of the inspection sensor in a metallic structure subject to vibrations using the aerial robot, including the data acquisition, analysis and interpretation of results. Traditional contact-based inspection methods are carried out by human operators, typically consisting of placing the sensor device in the point of interest. In this sense, the operator is responsible for determining the desired inspection point according to the observations of the environment and specific knowledge of the assessment. Therefore, in some cases it is not convenient or feasible to implement a fully autonomous inspection operation with an aerial robotic system, but it is convenient to allow the human operator to interact with the environment through the aerial robot. This is the scope of the research work presented in [10], in which a multi-rotor equipped with a passive and compliant end effector is teleoperated to exert contact forces using a haptic device that provides the user with feedback to improve his/her situation awareness. The paper is focused on the design of the bilateral teleoperation scheme and stability analysis to maintain contact forces in flight. Although the inspection and maintenance of industrial and civil infrastructures is one of the most immediate application areas of aerial robots, reference [11] extends the scope by proposing the application of drones for releasing sterilized insects, in order to prevent the increase in insect populations that could become vectors of disease transmission in urban and rural environments. Given the capabilities of Unmanned Aircraft System (UAVs), either fixed wing or rotary wing, to cover large areas following accurately desired paths in an autonomous way, the paper considers the current regulation challenges in Europe and risk assessment when flying over populated environments, particularly when the drone operates beyond the visual line of sight (BVLOS).
