Abstract
An UAV 1 performs a detachment control to detach a cargo supported by a support portion 117 or connected a connecting portion 118, and thereafter, performs a load detection process of detecting a mechanical load applied to the support portion 117 or the connecting portion 118. And then An UAV 1 performs different control according to the mechanical load, with respect to a movement of the UAV 1 after the detection of the mechanical load.
Claims14
A control method that is performed by a system including an aircraft that comprises a connecting portion configured to connect a cargo, the control method including:
- performing detachment control to detach the cargo that is connected by the connecting portion from the aircraft;
- performing a load detection process of detecting a mechanical load applied to the connecting portion after the detachment control is performed;
- performing, in a state in which the aircraft is flying, a success-failure determination of detachment of the cargo on a basis of the mechanical load;
- based on a determination that the detachment of the cargo has failed in the state in which the aircraft is flying, determining whether the aircraft can land safely;
- and
- performing different control according to the mechanical load, with respect to movement of the aircraft after the mechanical load is detected, the different control including causing the aircraft to land safely based on the determination the aircraft can land safely,
- wherein the connecting portion comprises a wire to which the cargo is connected and a reel that feeds or winding the wire, and
- wherein the determination whether the aircraft can land safely is based on a winding amount of the wire.
A control device for controlling an aircraft comprising a connecting portion configured to connect a cargo, 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:
- first control code configured to cause the at least one processor to perform detachment control to detach the cargo that is supported by the connecting portion from the aircraft;
- load detection code configured to cause the at least one processor to perform a load detection process of detecting a mechanical load applied to the connecting portion after the detachment control is performed;
- success-failure determination code configured to cause the at least one processor to perform, in a state in which the aircraft is flying, a success-failure determination of detachment of the cargo on a basis of the mechanical load;
- determining code configured to cause the at least one processor to determine, based on a determination that the detachment of the cargo has failed in the state in which the aircraft is flying, whether the aircraft can land safely;
- and
- second control code configured to cause the at least one processor to perform different control according to the mechanical load, with respect to movement of the aircraft after the mechanical load is detected, the second control code configured to cause the aircraft to land safely based on the determination the aircraft can land safely,
- wherein the connecting portion comprises a wire to which the cargo is connected and a reel that feeds or winding the wire, and
- wherein the determination whether the aircraft can land safely is based on a winding amount of the wire.
A control device for controlling an aircraft comprising a support portion configured to support a cargo or a connecting portion configured to connect the cargo, 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:
- first control code configured to cause the at least one processor to perform detachment control to detach the cargo that is supported by the support portion or connected by the connecting portion from the aircraft;
- load detection code configured to cause the at least one processor to perform a load detection process of detecting a mechanical load applied to the support portion or the connecting portion after the detachment control is performed;
- success-failure determination code configured to cause the at least one processor to perform, in a state in which the aircraft is flying, a success-failure determination of detachment of the cargo on a basis of the mechanical load;
- determining code configured to cause the at least one processor to determine, based on a determination that the detachment of the cargo has failed in the state in which the aircraft is flying, whether the aircraft can safely land based on a determination of whether the cargo extends below a leg portion of the aircraft;
- and
- second control code configured to cause the aircraft to land safely based on the determination the cargo does not extend below the leg portion of the aircraft.
