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.

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.

An unmanned aerial vehicle (UAV) has a multicopter section for flying in air with an attached blower section for generating an air stream for blowing dust off surfaces. A flight controller controls the multicopter section, a blower controller controls the blower section, and a power supply supplies power to the multicopter and blower sections. The flight controller and the blower controller are connected, and the blower controller is adapted to supply blower control commands to the flight controller to compensate for the thrust of the air stream from the blower section by flight control of the multicopter section. The UAV may be enclosed by a protective cage in the form of a meshed polyhedron, wherein the rods of the meshes are elastically connected at the respective nodes.

An unmanned aerial device having cleaning function includes a fuselage, a washing assembly and two propulsion assemblies. The washing assembly is disposed at a head of the fuselage. The propulsion assemblies are connected to two opposite sides of the fuselage. The two opposite sides are connected to the head. The propulsion assemblies each have an axial direction, and the axial direction is parallel to a direction from a bottom of the fuselage to a top of the fuselage.

A cleaning method includes controlling an unmanned aerial vehicle (UAV) to fly to a region of a wall body according to a path to be cleaned, and, in response to detecting a cleaning prohibition identifier associated with the region, recognizing the region as a cleaning prohibition region and controlling the UAV to fly over the cleaning prohibition region without cleaning the cleaning prohibition region.

The invention relates to a method of disinfecting clean rooms for administration of a disinfectant, which is sprayed onto the surfaces to be disinfected by means of an unmanned aerial vehicle from the air; the disinfectant being stored on board the aerial vehicle in at least one tank. The invention further relates to a device for performing this method, comprising an accordingly adapted unmanned aerial vehicle.

Disclosed herein is the next step in cleaning evolution with my new Automatic Multi-Attachment Changing Station (AMACS). The AMACS System has three separate product lines that combine the best of all worlds, hands free, with computer touch screen integration.

A detector system for detecting at least one of dust, dirt, snow, and ice, comprising: one or more sensors configured to detect the at least one of dust, dirt, snow, and ice; and one or more processors configured to perform instructions, the instructions configured to cause the one or more processors to receive an indication from the one or more sensors relating to a detection of at least one of dust, dirt, snow, and ice, wherein the system comprises a light source, a dust panel, and a light detector.

A cleaning method includes controlling an unmanned aerial vehicle (UAV) to fly to a region of a wall body according to a path to be cleaned, determining a distance between the UAV and a wall surface of the region of the wall body based on a cleaning mode, and controlling the UAV to clean the wall surface via the cleaning mode and at the determined distance away from the wall surface.

Method for inspecting and/or manipulating a beam at a lower side of a roof or deck, the beam including a strip, the method comprising the steps of: providing an unmanned aerial vehicle, UAV, wherein the UAV comprises a body, a number of rotors, a first arm; and an inspection and/or manipulation tool; while the first arm is in the first position, flying the UAV towards the beam; when the UAV contacts the beam, moving the first arm from the first position to the second position such that the end of the first arm is moved to a position vertically above the strip; reduce the propulsion force until the UAV hangs from the beam with the end of the arm in contact with and supported by the strip; and inspecting and/or manipulating the beam, using the inspection and/or manipulation tool, while the UAV hangs from the beam.
