Description

Drone with Collision Avoidance Function The present invention relates to a drone, and more specifically, to a drone equipped with an avoidance function capable of preventing collision with another adjacent drone during flight. This invention was derived as a result of the following research and development project. Research Project Name: Establishment of a Comprehensive Testbed and Commercialization of Core Components for Future Wingless PAVs Organizer: K-Robot Co., Ltd. Research Management Agency: Incheon Fab Urban Air Mobility Industry Promotion Association Research Period: July 2, 2024 – September 30, 2024 A drone refers to an unmanned aerial vehicle capable of flying and being controlled by radio guidance, and it is used in various fields, including not only commercial but also military and educational applications. In particular, for educational drones, multiple trainees typically fly the drones in confined spaces such as gymnasiums; recently, however, swarm flight is also being implemented for commercial and military purposes, where multiple drones collaborate to fly simultaneously and perform missions. Therefore, various methods have been proposed to prevent collisions between a drone and obstacles, including other adjacent drones. However, conventional collision avoidance methods require the detection of the location of obstacles expected to collide along the drone's flight path. In particular, if an obstacle is moving, detection or prediction of its movement path is necessary; consequently, the configuration required to implement this becomes complex and costs increase. Especially for educational purposes, where low-cost, lightweight drones are typically used, it becomes practically impossible to implement such a complex configuration.
