About

Shengrui Yu is a leading researcher in robotic spray painting, with a primary focus on modeling and optimizing paint deposition for complex surfaces. His work addresses a critical challenge in automated manufacturing: achieving uniform paint film thickness on free-form objects. Yu’s major contributions include developing a paint deposition rate model that directly informs automatic trajectory programming for robotic sprayers, a key factor for process parameter optimization. His 2011 paper on this model has garnered 22 citations, demonstrating its foundational impact in the field. Additionally, Yu introduced the curvature circle method for estimating paint deposition patterns on free-form surfaces, a novel approach that accounts for surface geometry to improve coating accuracy and uniformity. This 2010 work, with 14 citations, has been instrumental in advancing robotic air spray painting for industrial applications. By bridging theoretical modeling with practical implementation, Yu’s research enables more precise, efficient, and consistent paint application, reducing waste and enhancing quality in manufacturing. His contributions are essential for students and researchers exploring automation, surface coating, and robotics in industrial processes.
