The UAV control unit can be preloaded with a spray plan and a flight plan, or the UAV can be controlled by a user.

The present application provides a method for renovation works on a building that has a plurality of building elements, for example walls. The method includes: receiving scan data of a building element of the building; (150) processing the scan data to determine at least one dimension of the building element and an initial property of the building element from the scan data; configuring (160) a building system for the building element to achieve a target property of the building element, the building system being configured according to the at least one dimension of the building element and according to the initial property of the building element; and generating instruction data (170) for fabricating the building system. There is also provided an apparatus for renovation works on a building that has a plurality of building elements, for example walls.

A roof coating sprayer including a cart assembly and a sprayer assembly. The cart assembly has a frame with a plurality of wheels. The frame has a sprayer support assembly with a lateral member, and vertical spray nozzle attachment members arranged along the lateral member. The attachment members each mount a spray nozzle and can be vertically and horizontally shifted relative to the lateral member. The roof coating sprayer can be pulled over the surface of a roof at a uniform rate, enabling a coating of a uniform thickness to be sprayed on the roof. Additionally, the cart assembly can be self-propelled, enabling a uniform rate of speed for the cart and thereby enabling uniform application of coating.

Sprayer apparatus for use with an elongate boom may be configured to spray a liquid onto foliage on a ground surface. The sprayer apparatus may include a spray boom, a spray hood coupled to the spray boom, an extension member coupled to the spray boom, and a mounting apparatus coupled to the extension member. The mounting apparatus may be couplable to the elongate boom to support the spray boom and the spray hood above the ground surface.

A surface treatment vehicle for manufacturing a wind turbine blade is provided, the vehicle including: a transportation unit for locomotion of the vehicle, and a filling unit for applying a filler material on a surface of the blade, wherein the filling unit includes: a dispensing head for dispensing the filler material, the dispensing head being moveably attached to the transportation unit, and a tank for storing the filler material, the tank being attached to the transportation unit and fluidly connected to the dispensing head. Having the surface treatment vehicle with the filling unit allows an easier, faster, safer and more efficient manufacturing of a wind turbine blade.

The present disclosure provides for an automated spray system (100) to produce an elastomeric pad on a railroad tie. The automated spray system (100) includes a two-component spray system (102) for spraying a two-component reaction mixture to produce the elastomeric pad on the railroad tie. The automated spray system further includes a gantry system (140) having girder (146) that supports the spray applicator.

The present describes a work vehicle where an operator can, on the work vehicle side, confirm which working machine is engaged and set which working machine to engage. A tractor, to which a working machine can be mounted, is provided with: a liquid crystal panel selectably displaying an engageable working machine mounted and displaying the currently engaged working machine so as to be identifiable; an operation unit (encoder dial, enter button, and command buttons) for carrying out selection and determination operations for the working machine displayed on the liquid crystal panel; and a control device that, when a determination operation is carried out by the operation unit for a desired working machine, disengages the currently engaged working machine, and configures the working machine for which the determination operation has been carried out to be engaged.

The embodiments herein discloses a semi-autonomous mobile robotic apparatus (100) that can apply primers and paints and perform other operations such as wall sanding, drawing abstract wall art on the interior walls of buildings. The disclosed semi-autonomous mobile robotic apparatus (100) apparatus comprises of at least 13 numbers of type-1 (403) and at least 2 numbers of type-2 (405) ultrasonic sensors coupled to the apparatus (100), at least 2 Light Detection and Ranging (LiDAR) sensors (401 and 402) coupled to the apparatus (100), a human machine interface module (102) adapted to receive one or more inputs from a user (101) and provide the data to the microprocessor (103) for processing inside the apparatus (100) and provide output to one or more modules (104 and 105) to perform the relevant painting, sanding, putty application or abstract wall art drawing operations.

A chute for a drop spreader assembly that includes a body having a vertical axis. A funnel portion of the body has an open top to receive flowable material, a dispensing chute portion of the body has a distal dispensing opening and extending along an angle with respect to the vertical axis, and a plurality of directional vanes of the body protrudes into a flowpath within the dispensing chute portion to direct flowable material to an even distribution pattern through the distal dispensing opening. In some forms, the dispensing chute portion can be divided into a central portion and lateral portions separated from the central portion by gaps adapted to receive structure associated with a snow removal device therethrough. Each of the central and lateral portions can have a plurality of directional vanes protruding into a flowpath thereof.
