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.

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 invention is a water fountain control system that utilizes cameras to analyze movements of a human subject, and actuates one or more water fountain controllers in response to the movements to create a display incorporating spray patterns of the flowing water. The camera system records video in real time and generates optical signals that are sent to a processor running software that assesses the dimension, position, stance, and/or motion of the human subject and converts the data into recognized classes of movements and/or poses. Once the processor identifies the type of movements and/or poses, it sends signals to the actuators of the water fountains to control the fountains in a manner that implements stored predetermined visual effects generated by the fountain to create a visual presentation to an audience.

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 system includes a first nozzle assembly positioned along a boom assembly. The first nozzle assembly includes a first valve operably coupled with a first nozzle. A first imaging device is associated with the first nozzle assembly. A second nozzle assembly is positioned along the boom assembly and includes a second valve operably coupled with a second nozzle. A second imaging device is associated with the second nozzle assembly. A computing system is operably coupled with the first nozzle assembly, the first imaging device, the second nozzle assembly, and the second imaging device. The computing system is configured to receive data from the first imaging device, identify a first reference point within the data provided by the first imaging device, receive data from the second imaging device, identify a second reference point within the data provided by the second imaging device, and determine a boom deflection model.

A fluid dispenser includes a pump, a motor, a nozzle, a near field sensor, and a controller. The near field sensor is configured to sense a presence of an object within a predetermined distance away from the near field sensor. The controller is configured to determine the presence of the object within the predetermined distance for a first predetermined amount of time. In response to the determination, the controller is configured to activate the pump to push fluid in a first direction. The controller is configured to determine an absence of the object within the predetermined distance of the near field sensor. The controller is configured to reverse operation of the pump for a second predetermined number of rotations to draw the fluid in a second direction that is opposite the first direction in the absence of the object within the predetermined distance of the near field sensor.

A system for an agricultural operation includes a first vehicle having an object sensor configured to capture data associated with one or more objects within the field and a location sensor configured to capture data associated with a location of each of the one or more objects. A computing system is communicatively coupled with the object sensor and the location sensor. The computing system is configured to identify at least one of the one or more objects as a weed, classify each of the identified weeds in a first set of weeds or a second set of weeds, and generate a weed map based on the classification of each of the first set of weeds and the second set of weeds.

Sports field marking equipment includes a) a paint applying means adapted for marking a sports field on a surface; b) a position determining device configured for determining the position of the sports field marking equipment; c) a distance sensor configured for detecting a goal and/or corner post and the distance thereto; d) a first processor; and e) a first memory coupled to the first processor. The first memory includes program instructions executable by the first processor for receiving a goal and/or corner post detection signal and the measured distance from the distance sensor to the goal and/or corner post; receiving the position and direction of the sports field marking equipment from the position determining device at the time of receiving the detection signal; computing waypoint coordinates of the goal and/or corner post based on the received data; and storing the computed waypoint coordinates of the goal and/or corner post.

Methods of dispensing fluid are disclosed. A first applicator is positioned above a first dispense site at a first dispense region of a first electronic substrate by moving the first applicator using a primary positioner. A second applicator is simultaneously positioned above a first dispense site at a second dispense region of the first electronic substrate by moving the second applicator together with the first applicator using the primary positioner and moving the second applicator relative to the first applicator using a secondary positioner. It is then determined that the first or the second dispense region is misaligned relative to the other of the first or the second dispense region. Fluid is dispensed from the first applicator while moving the first applicator using the primary positioner to form a first fluid pattern at the first dispense region and fluid is simultaneously dispensed from the second applicator while moving the second applicator using the primary positioner and the secondary positioner.

The invention relates to a spray unit comprising an axle (20), a disc (30), a disc shape modifying assembly (40) and a liquid applicator (50). The disc is configured to spin about the axle centred on the centre of the disc. The liquid applicator is configured to apply liquid to a surface of the disc. The disc shape modifying assembly is configured to modify the trajectory of the liquid droplets that leave the spray unit by way of varying the diameter of the disc.
