A self-propelled robot unit including a navigation system and movement items for positioning of the robot unit on an even base and a system for impacting predefined areas of the base during the unit's movement between two points on the base is provided. The robot unit's system for impacting predefined areas of the base includes at least one effect unit provided by an outer side of the wheels in relation to the center axis, but upwards one of the driven wheels. An embodiment also relates to a method for creation of a plan for the robot unit's movements and placement of markings for a ball game field.

A coating apparatus and method allow for precise control of the application of a coating material on a substrate and provides a data recording system which is useful for certifying a coating job and assessing when and where any abnormalities occur.

A system for striping a roadway marking onto roadway surface either for rehabilitating the current roadway marking or duplicating a previously recorded roadway marking with a computer having a machine learning program to process the roadway marking image and position the marker at the desired roadway marking location.

A liquid application apparatus sequentially moves to each of a plurality of divided areas obtained by dividing a liquid application area and discharges liquid to connect images. The liquid application apparatus includes an imager and processing circuitry. The imager reads a reference position set in an area where end portions of the plurality of divided areas overlap with each other. The processing circuitry sets the reference position to a reference origin of image writing.

In an example, a surface marking robot comprises a body, a print apparatus comprising a plurality of print nozzles mounted on the body, a position detection apparatus to determine a position of the robot, and a motion control system, to cause the robot to travel along the surface with an intended path. The print apparatus may be to deposit print material onto the surface from a first nozzle of the plurality of nozzles to form a line as the robot follows the intended path and upon detection by the position detection apparatus that the position of the robot has deviated from the intended path, the motion control system may be to perform a correction to a direction of travel of the robot such that the robot returns to the intended path; and the print apparatus may be to deactivate the first nozzle and activate a second nozzle of the plurality of nozzles, wherein the second nozzle may be chosen such that a distance between the first and second nozzles is to compensate for a deviation of the robots position from the intended path.

A road marker system for dispensing a plurality of markings at a uniform distance on a road. wherein the road marker system comprises a frame. wherein, the frame is configured to attach a spraying assembly to a vehicle and position the spraying assembly at a visible distance from a vehicle driver. A chain assembly comprises a plurality of sprocket wheels with a chain wrapped circulating around the plurality of sprocket wheels. A circulating striker assembly is attached to an exterior portion of the chain. wherein, the circulating striker assembly is configured to circulate around the chain as the chain circulates around the plurality of sprocket wheels. The road marker system further comprises a valve nozzle release having a paint bottle.

A method of spraying paint using a painting assembly attached to a distance measuring wheel includes: receiving, by a communication device of the painting assembly, a control signal for controlling a driving device of the painting assembly; and based on the control signal, controlling a paint spraying state of a paint can attached to a paint can fixing device.

An automatic and intelligent spraying device for traffic marking intelligent. The spraying device for traffic marking includes a fixed bottom plate, a coating storage tank, a control box provided with a controller, an armrest, a row of nozzles, a speed sensor, and a driving motor. The coating storage tank is connected with coating pipes equipped with an electromagnetic valve. The fixed bottom plate is provided with a driving motor and rotating wheels. The driving motor drives the rotating wheels to move. The speed sensor is electrically connected with the controller and the driving motor. The controller controls a speed of the driving motor according to speed information detected by the speed sensor. The controller controls the driving motor, and controls the row of nozzles to spray according to a preset spray marking and spray pattern through the electromagnetic valve.

This application provides an intelligent two-dimensional traffic marking spraying device, to reduce the construction amount of workers, improve the construction quality and the work efficiency. The intelligent two-dimensional traffic marking spraying device includes a baseplate, a coating storage tank, a control box, a armrest, a row of nozzles, a speed sensor, a drive motor and four rotary shafts. When spraying traffic marking, the builders first select the marking, then set the next base point, and turn on the main switch. The coating contained in the coating storage box enters into the nozzle and sprays out. Meanwhile, the solenoid valve opens and closes at the corresponding position through the feedback information of the speed sensor and the control of the controller, so as to achieve the purpose of spraying two-dimensional traffic marking.

Location systems and methods for locating paint and other markings on a surface are disclosed. A paint marking stick may include a magnetic field sonde that is actuated in conjunction with dispensing of paint or other markers, where the sonde generates a magnetic field signal in conjunction with dispensing of paint or placement of a marker. A corresponding utility locator may receive the sonde magnetic field dipole signal and determine and store positional information and type information associated with the paint or other marker.
