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 software process for controlling a configurable UAV that includes a plurality of databases of crop plants, herbicides, insecticides and weeds. An area is defined to be treated. Thereafter, a scout UAV with an on-board camera is flown over the pre-defined area. Images detected by the camera are compared with the crop, pest and weed databases to respectively identify the crop plants, insects, and weeds. The insects and weeds are then subjected to a spot blast of pesticide/herbicide to kill them. Thus, the process results in a more efficient application of treatment chemicals which leads to less adverse environmental impacts associated with the use of pesticides and herbicides.

Provided are an Unmanned Aerial Vehicle (UAV) operating method and device. The method includes that: mapping information of an operation object to be operated is acquired, the mapping information including a safe height, geographic position information and a spray radius, of the operation object; a flight height of the UAV is adjusted to the safe height, and the UAV flies, according to the safe height, to a position corresponding to the geographic position information; and at the position corresponding to the geographic position information, a spiral spraying operation is performed on the operation object based on the spray radius (103).

An agricultural unmanned aerial vehicle (UAV) includes a fuselage, a flight power apparatus, a plurality of spray nozzles, a plurality of water pumps, and a controller. The flight power apparatus is mounted at the fuselage. The plurality of spray nozzles are installed below the flight power apparatus. The plurality of water pumps are connected to the plurality of spray nozzles and configured to deliver liquid to the spray nozzles. The controller is electrically coupled to the plurality of water pumps, and configured to selectively control one or more of the plurality of water pumps to pump the liquid to one or more of the spray nozzles connected to the one or more of the water pumps.

A wired vehicle fleet having a first vehicle connected with a supply unit by a first bendable connection element and a second vehicle connected with the supply unit by a second bendable connection element is controlled by a control unit to avoid a collision between the first and the second bendable connection elements.

A multi-modular aerial firefighting control method and apparatus for use by firefighters to control fire. The multi-modular aerial firefighting control method and apparatus generally includes multi-modular units that are held together to form an aerial firefighting system. The modular units may work together or independently. The multi-modular system comprises more than one modular unit, fluid, fluid conduit, reservoir, air flow generator, multi-modular unit support structure, aerial suspension system and aerial lift system.

A driving device, a spraying device having the driving device, and an unmanned aerial vehicle having the spraying device are provided. The driving device includes a driving assembly and an abutting assembly. The driving assembly includes a driving motor (31). The driving motor (31) has a driving shaft (32). The abutting assembly is connected to the driving assembly and exerts an acting force on the driving shaft (32) to abut against the driving shaft (32).

A remote operation spray device configured to depress-operate a spray nozzle of a spray device from a remote location. Device generates adequate pushing force required for depression and, by achieving weight reduction of the device proper, enables easy mounting on an aerial vehicle or other mobile unit. Device includes a main body fixedly attached to a mobile unit, a holder fixedly retaining a spray cartridge and a spray mechanism for jetting spray. The spray mechanism includes a base member, a depressing member pivotably attached to the base member for pressing down a spray nozzle, a pushed member provided at a distal end of the depressing member, and a pusher installed on the base member for pushing the pushed member to move horizontally. The horizontal pushing action of the pusher pushes and moves the pushed member to pivot the depressing member and press the spray nozzle vertically downward.

An aircraft, system, and method for sensing and/or releasing chemical agents by an aircraft is disclosed. The aircraft, system, and method may employ a chemical sensor, a wind sensor, an imaging device for capturing environmental features, and/or a processor operably coupled therewith. The processor may be used for collecting data from the chemical sensor, the wind sensor, and the imaging device to identify a navigational waypoint and to provide commands to the chemical sensor or to the aircraft based at least in part on collected data.

A method of weed control is provided. The method comprising: (a) determining development of flowers of at least one weed species of interest; and (b) artificially pollinating at flowering the flowers of the at least one weed species of interest with pollen that reduces fitness of the at least one weed species of interest. Also provided are systems for executing the method.
