About

Ki-Yin Chang is a researcher specializing in mobile robotics, with a particular focus on path planning and navigation algorithms. His work centers on developing intelligent computational methods that enable mobile robots to navigate complex environments filled with obstacles of arbitrary shapes and weighted regions. Chang's most significant contribution is his development of path planning approaches grounded in higher geometry maze routing algorithms. His methodology involves analyzing a top-view workspace, extracting free navigable zones by virtually expanding obstacles, and computing optimal traversal paths — a technically elegant solution to a longstanding challenge in autonomous robot navigation. His 2008 paper, "Optimal Path Planning for Mobile Robot Navigation," stands as his most impactful work, accumulating 123 citations and demonstrating the enduring relevance of his algorithmic framework to the robotics research community. This built upon his earlier 2004 study introducing the foundational maze routing approach, which established the conceptual groundwork for his subsequent advancements. For students and researchers working in autonomous systems, motion planning, or human-robot interaction, Chang's contributions offer both theoretical rigor and practical applicability. His progression from foundational algorithm design to optimized navigation solutions reflects a focused and methodical research trajectory that continues to influence the field of mobile robotics.
