A discharge apparatus for an aerial vehicle is provided which is capable of mounting an aerosol container by effectively utilizing a space outside an airframe. The discharge apparatus for an aerial vehicle, in which a content is discharged through a nozzle from an aerosol container mounted on an airframe, is characterized in that the aerosol container is mounted outside the airframe, and is arranged so that a central axis of the aerosol container is along a pitch axis of the airframe, or arranged on an extension portion such as a small wing extending from a fuselage of the airframe, an arm portion provided with a rotor blade, a leg portion for taking off and landing, or the like, with the aerosol container and the nozzle being connected to each other through a tube.

The present invention relates to an aerial vehicle (10). aerial vehicle comprises a liquid chemical tank (20), at least one liquid spray unit (30), at least one actuator (40), a plurality of sensors (50), and a processing unit (60). The liquid chemical tank is configured to hold a liquid chemical. The at least one liquid spray unit is configured to spray the liquid chemical. The at least one actuator is configured to operate the at least one liquid spray unit. At least one sensor (51) of the plurality of sensors is configured to measure a speed of the aerial vehicle relative to the ground. At least one sensor (52) of the plurality of sensors is a light detection and ranging (LIDAR) sensor configured to measure the direction and distance of airborne particles relative to the aerial vehicle with respect to a fore-aft axis of the aerial vehicle. The processing unit is configured to determine an air movement direction and distance relative to a projection of the fore-aft axis onto the ground and determine an air movement speed relative to the ground. The determination comprises utilisation of the speed of the aerial vehicle, the direction and distance of airborne particles relative to the aerial vehicle with respect to the fore-aft axis of the aerial vehicle and the speed of airborne particles relative to the aerial vehicle. The processing unit is configured to control at least one flying operation of the aerial vehicle and/or control the at least one actuator. Determination of at least one instruction for the control of the at least one flying operation of the aerial vehicle and/or determination of at least one instruction for the control the at least one actuator comprises utilisation of the determined air movement direction and distance relative to the projection of the fore-aft axis onto the ground and the determined air movement speed relative to the ground.

A method for performing one or more tasks on a surface via an unmanned aerial vehicle (UAV) or aerial robotics system (ARS) includes tethering a first UAV to a ceiling, a vertical wall, or a second UAV via a tethering cord with an extendible and retractable length, performing at least one task via the first UAV to an object during flight of the first UAV, sensing at least one parameter of the surface of the object via a task sensor, and resiliently adjusting an adjustable sensor arm of the first UAV to facilitate performance of the task(s). The adjustable sensor arm may support the task sensor and be resilient to impact forces caused by direct contact of the task sensor or the adjustable sensor arm with the surface. The tethering cord may be extended or retracted via at least one motor while the first UAV performs the task(s).

In one embodiment, a boom for a sprayer vehicle, comprising: a fluid-carrying medium; one or more first nozzles fluidly coupled to the fluid-carrying medium; and plural unmanned aerial vehicles tethered together, the plural unmanned aerial vehicles each comprising plural fans, wherein the one or more first nozzles are arranged to discharge material through one or more fans of the plural fans.

There is provided an industrial machinery system including an industrial machine, an area information acquiring device that acquires information on an operation area where the industrial machine is to be caused to perform an operation, and a control apparatus that determines whether to perform the operation by the industrial machine in the operation area, wherein the control apparatus includes a storage section that stores information on a registered area, the information being acquired in advance, and a determining section that determines whether to perform the operation by the industrial machine in accordance with whether an area corresponding to the operation area is identifiable from the registered area stored in the storage section.
