A method for automatic glue-spraying of stringers and inspection of glue-spraying quality based on measured data. Three-dimensional (3D) point cloud data of a stringer-skin assembly is collected by 3D laser scanner, and then processed by denoising and sampling. Feature points of an intersection line of a site to be glued of the stringer-skin assembly are extracted by K-means clustering method based on Gaussian mapping, and a minimum spanning tree is constructed based on a set of the extracted feature points. A connected region is established to obtain an initial feature intersection line of the string-skin assembly, which is optimized by random sample consensus algorithm to remove redundant small branch structures to obtain the actual glue-spraying trajectory. The quality of the glue sprayed on the stringer-skin assembly is inspected by line laser to determine positions of the defects, which are then subjected to secondary glue-spraying.

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.

A powder suction and discharge apparatus including a pipe, a container that is coupled to the pipe, a valve that opens and closes a passage of the pipe, and a pressure reducing mechanism that causes an internal space of the container to have negative pressure, in which in a first state in which the valve is open and the pressure reducing mechanism is driven, powder is sucked into the container through the pipe, in a second state in which the valve is closed, the sucked powder is stored in the container, and in a third state in which the valve is open, the stored powder is discharged through the pipe.

The disclosure relates to a device that saves water, energy, and money and may record the savings with a software analytics dashboard. The device allows cold water to flow out when the shower is first turned on and slows or shuts water flow once the water is heated and the shower is unoccupied. After the presence of the user is detected, the shower flow may resume.

An automated painting system that includes a robotic arm and a painting end effector coupled at a distal end of the robotic arm, with the painting end effector configured to apply paint to a target surface. The painting system can also include a computing device executing a computational planner that: generates instructions for driving the painting end effector and robotic arm to perform at least one painting task that includes applying paint, via the painting the end effector, to a plurality of drywall pieces, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one painting task.

A makeup machine includes a housing, a rotating platform, a spray head, moving means, and a controller circuit. The rotating platform rotates in the housing around a vertical center axis. The spray head is coupled to the rotating platform. The spray head is operative to receive a spray cartridge, and cause the spray cartridge to spray a material contained therein on a target area of a user's skin. The moving means moves the spray head vertically and horizontally relative to the target area. The moving means is coupled to the rotating platform and rotates with the rotating platform. The controller circuit within the housing controls movements of the rotating platform and the moving means.

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 a painting robot and a painting method using the painting robot. The painting robot includes: an arm control unit which controls operation of the robot arm; a head control unit which controls driving of nozzles of the nozzle head; a distance measuring device which measures the distance between the painting portions and the nozzle discharging surface; and an image processing portion which forms a three-dimensional model for painting, which is a three-dimensional model, based on the painting coverage of the vehicle expected to be painted. The head control unit, based on the distances measured between the painting portions in the three-dimensional model for painting and an imaginary nozzle head or the distances measured by distance measuring device, controls to discharge paint from nozzles with distances within the prescribed range, and to not discharge paint from nozzles outside the prescribed range.
