If the child drone 300 is not wirelessly connected to the parent drone 200 (No in S5001), the process returns to step S5001. Next, the child drone 300 detects whether or not there is any change in the tension of the wire 600 by the tension sensor 333 (S5003).

以下では、本実施の形態における宅配ボックス1140、システム1107および方法の基本的な構成は、実施の形態7等の配送システムの基本的な構成と同じであり、宅配ボックス1140の基本的な構成は、実施の形態15等の宅配ボックスの基本的な構成と同じであるため、本実施の形態におけるシステム1107および宅配ボックス1140の基本的な構成について適宜説明を省略する。本実施の形態では、システム1107が宅配ボックス1140等を有する点で実施の形態7等と相違する。
無人航空機1171が荷物を宅配ボックス1140に格納する動作を説明する。
次に、本実施の形態に係る宅配ボックス1140、システム1107および方法の作用効果について説明する。
例えば、上記実施の形態または上記実施の形態の変形例において、子ドローンは、車両の様にレールの上を走行する車輪を有していてもよい。子ドローンは、建物のレールを走行する間だけ、車輪によって自走してもよい。この場合、レールは、子ドローンが走行可能な板状であってもよい。レールは、子ドローンが落下しないように建物と反対側の端縁にガイドレールが配置されていてもよい。このため、安全性を確保することができる。
第1の態様に係る制御方法は、第1の無人航空機と、前記第1の無人航空機に連結線で連結された第2の無人航空機とを含むシステムにおいて、前記第1および第2の無人航空機を制御する制御方法であって、(A)前記第1および第2の無人航空機を前進させ、(B)前記第2の無人航空機の飛行に異常が生じたときに、前記第1の無人航空機の前進を止めさせる。
