Abstract
An unmanned aerial vehicle includes: a mooring member capable of mooring an article; a linear member connected to the mooring member; a reel around which the linear member is wound. The unmanned aerial vehicle acquires information relating to wind strength around the article when the article is to be lowered from the unmanned aerial vehicle by controlling the reel; and controls the reel so as to provide a feeding amount of the linear member in dependence on the wind strength, on the basis of the acquired information.
Claims17
A control device configured to control a reel to lower an article from an unmanned aerial vehicle equipped with a mooring member enabling mooring of the article, a linear member connected to the mooring member, and the reel on which the linear member is wound, the control device comprising:
- at least one memory configured to store program code;
- and at least one processor configured to access the program code and operate as instructed by the program code, the program code including:
- acquisition code configured to cause the at least one processor to acquire information relating to wind strength around the article when the article is to be lowered, wherein the information relating to wind strength comprises a displacement amount of the article in a horizontal direction with respect to a vertical direction;
- and
- control code configured to cause the at least one processor to control the reel, on the basis of the acquired information, so as to provide a feeding amount of the linear member in dependence on the wind strength,
- wherein the control code is configured to cause the at least one processor to control the reel so as to feed the linear member at a first predetermined speed to a first feeding amount in a case where the displacement amount is equal to or less than a first threshold value.
An unmanned aerial vehicle comprising:
- a mooring member capable of mooring an article;
- a linear member connected to the mooring member;
- a reel around which the linear member is wound;
- at least one memory configured to store program code;
- and at least one processor configured to access the program code and operate as instructed by the program code, the program code including:
- acquisition code configured to cause the at least one processor to acquire information relating to wind strength around the article when the article is to be lowered from the unmanned aerial vehicle by controlling the reel, wherein the information relating to wind strength comprises a displacement amount of the article in a horizontal direction with respect to a vertical direction;
- and
- control code configured to cause the at least one processor to control the reel so as to provide a feeding amount of the linear member in dependence on the wind strength, on the basis of the acquired information,
- wherein the control code is configured to cause the at least one processor to control the reel so as to feed the linear member at a first predetermined speed to a first feeding amount in a case where the displacement amount is equal to or less than a first threshold value.
A control method executed by a computer for controlling a reel to lower an article from an unmanned aerial vehicle equipped with a mooring member enabling mooring of the article, a linear member connected to the mooring member, and the reel on which the linear member is wound, the control method comprising:
- acquiring information relating to wind strength around the article when the article is to be lowered, wherein the information relating to wind strength comprises a displacement amount of the article in a horizontal direction with respect to a vertical direction;
- controlling the reel, based on the acquired information, so as to provide a feeding amount of the linear member in dependence on the wind strength;
- controlling the reel so as to feed the linear member at a first predetermined speed to a first feeding amount in a case where the displacement amount is equal to or less than a first threshold value.
