About

Nelson L. Duarte Filho is a robotics researcher whose work bridges industrial automation and intelligent human-robot collaboration. His primary research areas include robotic welding automation, computer vision for manufacturing, multi-robot path planning, and human-robot interaction (HRI) in industrial settings. Duarte Filho’s most impactful contribution is an automated seam tracking system using passive monocular vision for linear robotic welding, published in 2017 and cited 9 times—a foundational work for shipbuilding and other heavy industries seeking precision without expensive sensors. He further advanced HRI in welding by designing situational awareness-oriented interfaces (2020, 8 citations), enhancing safety and efficiency for factory workers interacting with complex robotic systems. Earlier, he developed “Space D*” (2012), a novel path-planning algorithm combining D* graph search with space colonization for multi-robot navigation in unknown environments, demonstrating creative cross-domain thinking. While his citation counts reflect a focused, applied research trajectory, his work has direct industrial relevance, particularly for automated manufacturing and collaborative robotics. Duarte Filho’s research is notable for its practical orientation—solving real-world welding challenges while pushing the boundaries of how humans and robots work together safely and effectively.
