About
Chee Yap is a pioneering researcher in computational geometry, robotics, and algorithmic motion planning. His foundational work on the “retraction” method for motion planning, introduced in his 1985 paper (408 citations) and its 1983 precursor (145 citations), revolutionized the field by providing efficient algorithms for moving a disc among polygonal obstacles. Yap also made significant contributions to shape reconstruction through probing (124 citations) and coordinated motion planning for dual robot arms (48 citations), demonstrating his broad impact on robotic manipulation. His later work introduced pseudo-approximation algorithms for optimal motion planning (20 citations), advancing the theory of approximate solutions. Yap’s development of resolution-exact algorithms for link robots (7 citations) and soft subdivision motion planning (7 citations) further showcases his sustained influence on practical, theoretically-sound robotics. Beyond these, his design of the LINETOOL geometric editor (13 citations) highlights his commitment to bridging theory and application. With over 800 total citations across his most-cited works, Yap’s research has shaped algorithmic robotics for decades, making him a key figure for students and researchers exploring motion planning, computational geometry, and approximation theory.
