Abstract: An autonomous and self-mobile apparatus for applying a coating to a surface. The self-positioning apparatus can move into an interior or to an exterior of a structure, and can automatically apply a coating, such as paint, to a surface of the room, or a surface of the exterior of the structure, with little or no human intervention or assistance. The apparatus navigates and applies coatings using its sensors and a computer. In some implementations, the system may also include a storage, recharging, and monitoring unit that interconnects with the apparatus for applying a coating to a surface.
