Drone for spraying and brooming a concrete surface

A drone for selectively spraying a concrete surface, the drone comprising:

• a body frame;
• a plurality of boom assemblies, each boom assembly of the plurality of boom assemblies having a proximal end region disposed at the body frame and a distal end region linearly displaced from the proximal end region;
• a plurality of propulsion members, wherein each propulsion member of the plurality of propulsion members is disposed at the distal end region of one respective boom assembly of the plurality of boom assemblies, and wherein each propulsion member of the plurality of propulsion members comprises a motor and a propeller;
• a power source disposed at the body frame and operatively connected to the plurality of propulsion members, wherein, when the drone is operated to fly above the concrete surface, the power source energizes the plurality of propulsion members to apply lift to the drone;
• a fluid tank disposed at the body frame, wherein the fluid tank includes a fill opening in fluid communication with an interior area of the fluid tank;
• a spray bar including a plurality of spray nozzles in fluid communication with the fluid tank, wherein, when the drone is operated to fly above the concrete surface, the spray bar is disposed at a lower portion of the body frame, and wherein individual spray nozzles of the plurality of spray nozzles are spaced apart from one another at the spray bar;
• and
• a fluid pump in data communication with the power source and operatively connected to the plurality of spray nozzles, wherein the fluid pump is configured to actuate the plurality of spray nozzles when energized to spray a fluid from the fluid tank onto the concrete surface.
