Abstract

Le problème décrit par la présente invention est de permettre à un drône de fonctionner en coopération avec une unité mobile qui est mobile, sur laquelle le drône est monté, peut atterrir et décoller, de telle sorte qu'une sécurité élevée peut être maintenue même lorsque le drône vole de manière autonome. La solution selon la présente invention porte sur un système de drône (500) dans lequel un drône (100) fonctionne en coopération avec une unité mobile (406a) qui est mobile, sur laquelle le drône est monté, peut atterrir et décoller. L'unité mobile est pourvue : d'une région d'atterrissage et de décollage (82) dans laquelle le drône est monté et qui sert de point d'atterrissage et de décollage (406) où le drône effectue l'atterrissage et le décollage; d'une unité de commande de mouvement (30) qui est capable de déplacer l'unité mobile conjointement avec le drône monté sur l'unité mobile; et d'une unité de transmission d'unité mobile (31) qui transmet des informations concernant l'unité mobile. Le drône est pourvu : d'une unité de commande de vol (21) qui amène le drône à voler; et d'une unité de réception de drône (20) qui reçoit les informations concernant l'unité mobile. L'unité de commande de vol détermine un emplacement où le drône doit atterrir sur la base des informations concernant l'unité mobile, reçues par l'unité de réception de drône.
