The invention relates to a work vehicle (1) comprising an operable arm (10) adapted to handle a tool (A-D) fastened to the free end of the arm, a control unit (4) for controlling the work vehicle (1), a dust control system arranged to distribute water mist with the aim of retaining dust that is created when the tool is used. For efficient dust control, the dust control system comprises a pressure air source (31) and a water pressure source (21), an air duct (33) arranged for the tool (A-D), through which an airflow from the pressure air source (31) can be conveyed, an injection nozzle (26) directed against the airflow in the air duct (33), with which water from the water pressure source (21) can be sprayed into the airflow for atomization of the water into liquid drops, which together with the airflow form a water mist, whereby the air duct arranged for the tool (A-D) is directed, so that the liquid drops form water mist (36) in the surroundings of the tool.

The system includes a robot multi-jet system having a spray section, a drier section, and a catalyst section. The drier section includes a warm air blower, the catalyst section includes a photocatalyst tank, and the spray section includes a plurality of jet extensions. A first jet extension connected to the photocatalyst tank sprays a uniform layer of a photocatalyst through a first set of jets, and a second jet extension that is mechanically connected to the drier section and in fluid communication with the warm air blower is configured to spray a gas onto an inner surface of the glass tube with a second set of jets. Both the drier section and the catalyst section are mounted on wheels to move the system on the inner surface of the glass tube. A motor is electrically connected to a battery mounted within the robot and mounted to the wheels.

A coating system for applying coating liquid such as a base coat, a paint, a lacquer or a protective layer to surfaces of buildings, wind turbines, ships and aircraft. The coating system includes an unmanned aerial machine in the form of a helicopter for dispensing the coating liquid. The aerial machine has a fuselage, two rotors, a tank for holding the coating liquid, and an applicator for dispensing the coating liquid and outputting same onto a surface to be coated. In order to supply the tank with coating liquid, the tank is fastened to the aerial vehicle and the tank or aerial vehicle has a filling opening for refilling the tank in the landed state of the vehicle, and/or the tank is part of an exchangeable tank module coupled to the fuselage and/or is uncoupled from the fuselage by a coupling device controlled in an automated manner.

A fluid dispersion system and method used for spraying large areas with near-monodispersed, aerosolized fluid droplets. More specifically, the system creates and distributes a cloud of near-monodispersed droplets of fluid by pumping pressurized air and fluid through fluid dispersion machinery and into, and out of, a fluid dispersion nozzle. The fluid dispersion machinery is a combustion engine-driven air compressor system that includes an engine, radiator, fuel tank, fluid tank, fluid piping system, fluid pump, air compressor, air compression intake, one or more fluid dispersal nozzles, air ducting, clutch, and control system. The method of fluid dispersion is implemented at night during a nighttime air inversion when there is a temperature difference between the temperature of air at the top of an object and the temperature of air near the ground surface.

An autonomous moving apparatus includes a handheld housing adapted to contain a printing head, an actuating mechanism adapted to move the housing on top of a printing surface, an audio sensor, and at least one non-audio sensor selected from a group comprising a distance sensor, a touch sensor, and an image sensor. Processing circuitry is adapted to execute a code for analyzing an audio signal captured by the audio sensor to detect a voice command; in response to the detection of the voice command, analyzing readings of at least one non-audio sensor to identify a triggering event; in response to the detection of the triggering event, instructing the actuating mechanism such that the housing moves along a printing pattern associated with the triggering event, and instructing the printing head to print media extracted from the readings, selected according to an analysis of the readings.

A method for applying fluid to a travel lane is disclosed. The method may include receiving information related to a travel lane including a first set of tire paths and a second set of tire paths to be traveled by one or more vehicles, generating spray pattern control information for a fluid application machine having multiple spray heads based on the first set of tire paths and the second set of tire paths to be traveled by the one or more vehicles, and selectively triggering the multiple spray heads of the fluid application machine to alternately apply fluid to the first set of tire paths and the second set of tire paths based on the spray pattern control information and based on a current position of the fluid application machine on the travel lane.

It is suggested to provide a line marking device having a GNSS receiver or prism for a robotic total station. The line marking device further has at least one spray nozzle and a comparator adapted to compare a detected location to a predetermined pattern. The comparator calculates a location and/or a direction error. Further the line marking device has a prompting device for providing steering information to a user. The provided information is the location and/or direction error. The at least one spray nozzle and the GNSS receiver or the prism are in a fixed spatial relation to a connecting element, which is connected or connectable to an unmovable receiving element of a cart.

The present invention refers to an automated painting system on oil ships, being executed by a mobile platform and an oscillating arm. The assembly only works due to the control of cables, winders and wheels. This approach is aimed at painting large vertical walls. The painting deck suspension uses four cables, each connected to a pivot on the mobile platform, and two fixed pivots plus four winders. The winders contain a servo motor in a synchronous serial network. The cables are made of reduced-weight polyethylene. Each cable is connected exclusively to one winder. Suspension is achieved with the aid of two adapted cranes and initialization through the addition of a giraffe-type crane.

A spray machine autonomously traverses a roof while selectively spraying and rolling adhesive across the roof. To navigate the roof, the spray machine is most preferably fitted with GPS and other sensors to detect roof features and already coated adhesive. In one embodiment the spray machine has a spray and roll apparatus supported on an undercarriage and propelled by a drive train. Each of the spray nozzles and rollers are preferably supported upon respective boom arms, and reciprocate along the longitudinal axis of the boom arm. Each of the spray and roller boom arms have a longitudinal axis that extends transverse to the spray machine ordinary forward direction of travel. In another embodiment, combination spray and roller boom arms are hinged to the undercarriage, and so may be lifted from horizontal to vertical to avoid obstacles.

The autonomous paint spraying machine is an autonomous mobile system for making paint markings on surfaces. The autonomous paint spraying machine includes a chassis having longitudinally opposed first and second edges, where the first edge has a linear contour and the second edge has an arcuate contour. A linear track is mounted on the chassis adjacent the first edge, and an arcuate track is mounted on the chassis adjacent the second edge. A paint receptacle is mounted on an upper surface of the chassis, and a plurality of driven wheels are mounted on a lower surface of the chassis. A controller is configured for controlling actuation and orientation of the plurality of driven wheels. First and second spray nozzles each receive paint from the paint receptacle. The first spray nozzle is slidably mounted on the linear track, and the second spray nozzle is slidably mounted on the arcuate track.
