A discharge apparatus for discharging contents in an aerosol container, comprising, a first flow channel connected to an aerosol container; a second flow channel connected to the first flow channel; a support configured to support at least a part of the second flow channel; and a change unit configured to change a shape of the second flow channel, wherein the support changes a support position of the second flow channel in response to a change in a shape of the second flow channel, is provided. In addition, an unmanned aerial vehicle on which the discharge apparatus is mounted is provided.

Provided is a posture changing device for changing a posture of an aerosol container mounted on an unmanned aerial vehicle, the posture changing device including: a posture selecting unit for selecting a posture of the aerosol container from a plurality of candidate postures; and a posture changing unit for changing a posture of the aerosol container to the posture selected from the plurality of candidate postures. Also provided is a posture changing method for changing a posture of an aerosol container mounted on an unmanned aerial vehicle, the posture changing method including: selecting a posture of the aerosol container from a plurality of candidate postures; and changing a posture of the aerosol container to the posture selected from the plurality of candidate postures.

Provided is an unmanned aerial vehicle configured to be able to discharge a liquid, comprising: a container of the liquid; a discharging unit configured to discharge the liquid; and a coupling unit configured to couple the container and the discharging unit together, wherein the coupling unit includes a buffering unit configured to buffer stress generated in the coupling unit. The container may be an aerosol container. The coupling unit may include a rigid unit coupled to the buffering unit and configured to have rigidity higher than the buffering unit.

Provided is a discharge apparatus to which an aerosol container can be detachably mounted, the discharge apparatus including: a pressing unit configured to press a stem for opening and closing a valve of the aerosol container; and a buffer unit configured to buffer excess force, which is an amount of force by which force with which the pressing unit presses the stem has exceeded force to open the valve. The buffer unit may be configured to buffer the excess force exerted on the pressing unit by moving the pressing unit according to the excess force. The buffer unit may be configured to buffer the excess force exerted on the aerosol container by moving the aerosol container according to the excess force.

The present invention provides a flying apparatus that can accurately measure a weight of a transported objected in a simple configuration. The flying apparatus 10 includes rotors 11, motors 12, a flight sensor 13, an electric power conversion unit 14, and a computation control unit 15. The flight sensor 13 measures physical quantities acting on a fuselage base portion 16. The computation control unit 15 generates instruction signals based on the physical quantities to cause the fuselage base portion 16 to be at a predetermined position in a predetermined attitude. The electric power conversion unit 14 adjusts amounts of electric power supplied to the motors 121 and the like based on the received instruction signals. Moreover, the computation control unit 15 calculates an estimated weight that is an estimation value of a weight of the transported object, based on magnitudes of the instruction signals.

Mobile station to carry out aerial spraying operations for large surfaces by means of drones which comprises at least one of a machine room comprising at least one electricity generator and an energy backup system; at least one compartment for the storage and transport of drones; a mixing tank connected to a water storage tank; a loading and unloading equipment movable on at least one rail; a lifting equipment arranged outside and configured to lift an operator; a battery charging and transport compartment for drones, a lighting system, a resting place incorporated into the system, multiple hermetic and washable containers for the transport of chemical products, dispensers, chemical waste, personal protection elements, spill containment elements (sand, non-sparking shovels, swabs), clean clothes, dirty clothes, trash.

Provided is an unmanned aerial vehicle including: a discharge port configured to discharge contents in a container; an expansion/contraction unit configured to connect the discharge port and the container and be expandable; and a discharge position control unit configured to control expansion/contraction of the expansion/contraction unit.

There is provided a holding member including: a holding unit configured to hold a package with a variable volume; and a connection unit configured to connect the holding unit and an unmanned aerial vehicle. The holding member may include a posture change unit configured to change a posture of the holding member, and a posture fixing unit for the holding unit. The holding member may include a package fixing unit configured to fix the package to the holding unit. There is provided a spraying method in which in a state in which the holding member holds the package, and the holding member holding the package is mounted on the unmanned aerial vehicle, a content of the package is sprayed from the unmanned aerial vehicle.

Unmanned vehicles may be used to survey a property in response to or in anticipation of damage to the property. For example, an unmanned vehicle may use one or more sensors to determine damage to the property. Unmanned vehicles can be terrestrial, aerial, nautical, or multi-mode.

An unmanned aerial vehicle (“UAV”) system for energy transport includes a UAV having an energy tank configured to transport energy, a processor, and a memory. The memory includes instructions which, when executed by the processor, may cause the system to receive a first location for collecting or releasing the energy, determine an energy level of the energy tank, and transport the energy by the UAV to or from the first location based on the determined energy level.
