An effective implementation is shown for a height adjustment system for a plurality of spray guns used in a line striper.

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 ground sprayer includes a front portion and a rear portion. A marking fluid is stored in a fluid reservoir removably mounted in the front portion. A pump disposed in the front portion draws the marking fluid from the fluid reservoir through a manifold, and the pump drives the marking fluid out of a nozzle. An actuator is disposed in the rear portion and can activate the pump based on a command from the user. The rear portion includes a handle such that the user can fully support and operate the ground sprayer with a single hand.

A ground marking apparatus is configured to apply marking material to a ground surface. The ground marking apparatus includes a beam supported by a beam mount and extending along a beam axis. A carriage is disposed on the beam and movable on the beam along the beam axis. A carriage motor operably interfaces with the beam and is configured to move the carriage along the beam. A dispense arm is supported by the carriage and is configured to move relative to the beam as the carriage moves along the beam.

Apparatus for blending and applying plural substances including aggregate onto an environmental substrate is shown and described. The apparatus includes optionally a single power plant, plural pumps each fed by a respective hopper, and a blender blending pumped materials together. Dispensing ratios of the two pumps are mutually adjustable. An onboard air compressor delivers compressed air for atomizing blended materials as they are dispensed with the aggregate. Because materials may be curable or hardenable, flushing is enabled. The apparatus may be a free standing wheeled device.
