Abstract: To provide an unmanned rotorcraft and a method for measuring a distance to a circumjacent objet around the rotorcraft, enabling it to prevent its airframe from colliding with a circumjacent object when flying and prevent its airframe from falling down when landing, while suppressing an increase in airframe cost. This is solved by an unmanned rotorcraft including a distance sensor to measure a distance between its airframe and a circumjacent object around it, the distance sensor and its detection direction being fixed to the airframe, and a method for measuring a distance to a circumjacent objet around the rotorcraft, adapted to watch or watch out for a circumjacent object around the airframe by turning the airframe automatically in a yaw direction under predefined conditions or to measure a difference of elevation at landing points of all legs of the airframe.

Abstract: A living body search system includes an unmanned moving body and a server. The body includes: a camera; image data processing for retrieving image data; moving means; and communicating. The server includes: a database configured to record therein search data; and notifies a client. The body and the server are connected to each other through a communication network. The system includes individuals in the image data wherein individual identification information records the database to determine whether the candidate object in the image data is a searched-for object. The system registers, in the server, searched-for data provided in advance from the client. The system compares image data retrieved from the camera with the individual identification information to perform individual recognition. When the image data matches the individual identification information, the system determines that the object has been found. Then, the system notifies the client that the searched-for object has been found.
