Server apparatus, system, flight vehicle, and operation method for system

A first flight vehicle comprising:

• a communication unit;
• a control unit configured to receive an instruction from a server apparatus via the communication unit;
• a holding mechanism configured to hold a penetration tool,
• wherein the control unit is configured to, under control in accordance with the instruction, execute:
• energizing a penetration tool toward a target object placed in a predetermined space, holding a first part and a second part of a cord-shaped member attached to the penetration tool, the first part being penetrated through the target object, the second part not being penetrated through the target object, and flying to outside the predetermined space;
• handing over any one of the first part and the second part to a second flight vehicle waiting outside the predetermined space;
• and
• towing the target object with the cord-shaped member and transporting the target object to outside the predetermined space by flying together with the second flight vehicle while the first flight vehicle and the second flight vehicle are respectively holding any one and the other of the first part and the second part;
• and
• a gripping mechanism configured to tow the target object to a predetermined location in the predetermined space by gripping the target object,
• wherein when the first flight vehicle is inside the predetermined space, and is unable to ensure enough space to penetrate the penetration tool through the target object, the control unit is further configured to, under the control in accordance with the instruction, execute:
• towing, by the first flight vehicle, the target object to the predetermined location in the predetermined space by gripping the target object with the gripping mechanism, and energizing the penetration tool toward the target object after towing the target object to the predetermined location.

An operation method for a system including a server apparatus and a plurality of flight vehicles, the operation method comprising:

• sending, by the server apparatus, a flight instruction to a first flight vehicle and a second flight vehicle;
• energizing, by the first flight vehicle, a penetration tool toward a target object placed in a predetermined space, holding a first part and a second part of a cord-shaped member attached to the penetration tool, the first part being penetrated through the target object, and the second part not being penetrated through the target object, and flying to outside the predetermined space;
• waiting, by the second flight vehicle, outside the predetermined space and receiving any one of the first part and the second part from the first flight vehicle;
• and
• towing, by the first flight vehicle and the second flight vehicle, the target object with the cord-shaped member and transporting the target object to outside the predetermined space by flying while respectively holding any one and the other of the first part and the second part,
• wherein when the first flight vehicle is inside the predetermined space, and is unable to ensure enough space to penetrate the penetration tool through the target object, the method further comprises:
• towing, by the first flight vehicle, the target object to a predetermined location in the predetermined space by gripping the target object with a gripping mechanism, and energizing the penetration tool toward the target object after towing the target object to the predetermined location.
