In the wall spraying construction, a new construction mode is introduced, and a wall sprayingrobot is used to replace the manual spraying construction in a large area. However, at this stage, theconstruction efficiency of the wall spraying robot is far lower than its theoretical construction efficiency,that is, its application efficiency is too low. Through the research on the construction technology of wallspraying robot, its application efficiency of is greatly improved from the aspects of man⁃machinecoordination and coating mix ratio.
