Quality Control Parameters for Robotic Bridge Painting

摘要

To protect a steel bridge from corrosion, periodic painting is needed. Bridge painting operations are dangerous and hazardous to human health. A robotic bridge painting system is being developed to replace the human being. One major problem with robotic bridge painting is how to achieve the specified coating quality, which includes two aspects: (1) the coating thickness; and (2) the coating appearance. To ensure quality of the robotic bridge painting, the writers have investigated: (1) the parameters that affect the coating thickness and appearance; (2) the values of the parameters to achieve the required thickness and appearance for the robotic painting; and (3) the thickness distribution functions of the bridge painting under various conditions. The specified painting quality can be achieved by using the results of this study to set up and control the robotic bridge painting system.
