Provided are an unmanned rotorcraft and a surrounding object ranging method thereof, with which it is possible to prevent collisions between the body and surrounding objects during flight, and prevent the body from overturning when landing, while minimizing any increase in body cost. The present invention solves the problem through an unmanned rotorcraft and a surrounding object ranging method thereof, in which: a distance sensor is provided for measuring the distance between the body and surrounding objects; the distance sensor and the detection direction thereof are secured in the body; and the body is automatically rotated in the yaw direction on the basis of a prescribed condition, whereby surrounding objects near the body are observed and noted, or the difference in height between the landing points of the legs of the body is measured. |
