The article is devoted to the development of a module for automating the planning of trajectories for painting aircraft fuselage elements. The scientific problem of the lack of modern control methods and technologies at aviation assembly plants, namely, in robotic areas for painting parts, is posed. And the applied problem of the inappropriate use of robotic painting due to lengthy readjustment due to the lack of automated adjustment of the robot’s control program is posed. The stages of development and implementation of module calculations are presented: the stage of processing a 3D model of a part to identify key vertices, generating points for the painting trajectory of one face, generating a complex of painting trajectories for the entire part, corrective transformation of the trajectory into the coordinate system of the central point of the robot manipulator tool. Based on the obtained trajectory, an automated synthesis of the robot's control program was implemented. The use of a control program was demonstrated and conclusions were drawn about the performance of the painting path planning module: it was empirically established that the robot performs the path according to the requirements. In the future, the module will be integrated into a hardware and software complex for managing and correcting control programs for painting aircraft parts. The use of a software and hardware complex will allow for robotic painting, improve the quality of the applied paint layer, reduce the production time of products and the paint consumption, and this will reduce the cost of products.
