A system including an unmanned aerial vehicle (UAV) or aerial robotic system (ARS) to perform at least one task to an object during flight of the UAV in a movement mode configured for maneuvering near a surface of the object. A task sensor configured to sense at least one parameter of the surface. An adjustable sensor arm attachable to the UAV and supporting the task sensor to facilitate the task performed to the surface of the object by the UAV during flight of the UAV. The sensor arm being resilient to impact forces caused by direct contact of the sensor or sensor arm with the surface to bend, spring or swivel relative to a contour of the surface.

A drone system includes a drone aircraft connected to an air duct that terminates in a nozzle that emits a jet of air with a blowing force from the blower nozzle, such as for cleaning tall and hard to reach surfaces of structures and buildings or to otherwise blow objects, debris, substances and floating materials.

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.

A drone which can be piloted autonomously or by a user. The drone has an air treatment dispenser for spraying, or otherwise treating, a target area with one or more desired air treatments. The drone may operate as deemed desirable by a user, upon a predetermined schedule or in response to a demand signal from one or more target areas. By delivering the air treatments from an elevated position, the target area can be more uniformly and efficiently treated.

An unmanned aerial vehicle (UAV) comprises a controller. The controller of the UAV causes the UAV to access an interior of an object. The controller of the UAV causes the UAV to clean at least part of the interior of the object.

The invention discloses an automatic surface cleaning vehicle for photovoltaic (PV) panels (102) that is capable of moving on the surface of the said panel. The system comprises of a surface cleaning device (816) mounted on a retractable supporting frame which is collectively called as an Unmanned Autonomous Vehicle (UAV) (101). The invention provides for an automatic cleaning system that also collects data about the amount of dust accumulated on the surface of the photovoltaic panel (102) and details of any damage found on the surface. A motor driving circuit is further comprised in the unmanned, autonomous vehicle (101) to control direction and motion of the unmanned, autonomous vehicle (101).

An unmanned aerial vehicle, UAV, includes (i) a camera having a field of vision including, in use, a portion of a vehicle to be cleaned, (ii) a liquid container comprising waterless carwash liquid, (iii) a liquid dispenser operable to cause the waterless carwash liquid comprised in the liquid container to be dispensed from the liquid container, (iv) a cleaning implement, and (v) a controller communicatively coupled to the camera, the liquid dispenser and the cleaning implement. The controller is operable (a) to cause the liquid dispenser to dispense the waterless carwash liquid from the liquid container onto the portion of the vehicle to be cleaned and (b) to control the cleaning implement to clean the portion of the vehicle to be cleaned.

An unmanned aerial vehicle, as well as a method, a system, and a non-transitory computer readable medium provide a cleaning service for a vehicle. In an example embodiment, a method implemented by at least one unmanned aerial vehicle for providing a cleaning service for a vehicle is provided and includes cleaning the vehicle. The cleaning can include a washing process. The washing process can include flying according to a first path. The washing process can additionally include washing the vehicle using a washing module while flying according to the first path. The first path is based on 3D shape data of the vehicle.

A cleaning method and apparatus for elevated structures and ceilings, such as open girder truss systems, utilizes a multi-rotor blade helicopter/drone together with a contaminant entrainment system. More specifically, the drone includes a contaminant entrainment system including a vacuum and filter for entraining the contaminants dislodged from the elevated structures, a cleaning head to engage the surface to be cleaned, a system to guide the drone's flight path proximate the elevated structures to be cleaned, and optionally a power tether to reduce battery weight and increase the flight time of the drone.

An aircraft that can fly stably when water is discharged from a hose installed on the airframe, and an aircraft system, are provided. The aircraft system can include a master aircraft, slave aircrafts and a remote control device. The aircraft preferably fly as a unit. Each slave aircraft can include four rotary blade portions having propellers, and a suspending means for suspending a part of a hose. The master aircraft may include four first rotary blade portions having first propellers arranged to rotate in a horizontal plane, four second rotary blade portions having second propellers arranged to rotate in a vertical plane, and a nozzle on which a tip end part of the hose is installed. The direction of the center axis of the nozzle is parallel to the direction of the rotational axes of the second propellers.
