PROBLEM TO BE SOLVED: To provide an accessory permitting free flying of a drone, not only its movement above the ground and along a wall surface but also on a water level.SOLUTION: A drone 10 includes a body 12 and a plurality of propulsion units, each propulsion unit has a propeller 18 driven by a motor, and different motors can be driven by different ways so as to generate a rising force in attitude and speed to steer the drone. An accessory includes a shaft 20 removably fitted to the drone body in a horizontal direction X with respect to the main traveling direction of the drone at a point 22 aligned with the gravity center of the drone and set at a position higher than the gravity center. The accessory further includes two link elements 26 rotatably fitted to the drone body symmetrically and independently of each other at the ends of the shaft. The specific gravity of these link elements to water is less than 1, and the diameter of the link element is larger than the size of the entire drone.SELECTED DRAWING: Figure 3 |
