a docking hook configured to couple to the magnetic crawler, the docking hook comprising spring-loaded passive latches configured to passively:
release the magnetic crawler from the docking hook after the landing in order to deploy the magnetic crawler on the cylindrical surface;
receive the magnetic crawler into the docking hook after the deployment in order to retrieve the magnetic crawler from the cylindrical surface; and
secure the magnetic crawler to the body during the flight, during the landing, and during takeoff of the UAV from the cylindrical surface after the retrieval; and
a linear actuator coupling the docking hook to the body and configured to lower the docking hook and coupled magnetic crawler from the body to the cylindrical surface as part of the deployment, and to raise the docking hook and received magnetic crawler from the cylindrical surface to the body as part of the retrieval.
