Development of a new spraying robot for building waterproof materials

For roof and indoor and outdoor waterproof material coating operations, most companies still rely mainly on manual operations, including painting, rolling, manual spraying, and coil covering. There are phenomena such as low construction efficiency and uneven thickness control. In order to improve the construction process and better promote the application of spraying quick-setting products, this design has developed a robot spraying equipment with high accuracy, fast construction speed and convenient construction. Firstly, according to the area covered and the size of the obstacle, the robot's program will partition the whole area and determine the reciprocating working path. Secondly, design the mechanical structure scheme and clarify the technical route. A rotatable four-wheel mobile chassis is used to build workbenches and spray systems. Finally, this paper proposes a method of combining differential GPS and unit decomposition, combining the small area decomposed with high-precision differential GPS navigation and positioning, and designing a path planning algorithm.
