About

Ping-Lang Yen is a distinguished robotics and biomedical engineering researcher whose work spans surgical robotics, rehabilitation engineering, and human-robot collaboration. His research has made significant contributions to the development of intelligent control systems and robotic platforms for both medical and agricultural applications. Yen's early work explored pneumatic muscle actuators and self-organizing fuzzy control for rehabilitation and industrial robots, garnering 28 citations. He went on to pioneer surgical robotic systems, including a hexaglide-structured knee surgical robot with enhanced safety features and hybrid Cartesian parallel manipulators for high-precision bone cutting — work that laid important groundwork for cooperative force-controlled surgical platforms. His more recent contributions focus on handheld orthopedic surgical robots featuring tremor suppression, shared control frameworks, and active guidance, with these studies accumulating over 34 citations collectively. Beyond the operating room, Yen has extended human-robot cooperation principles to agricultural robotics, developing collaborative tea-harvesting vehicles with adjustable autonomy to address labor shortages in narrow terrain environments. Across his career, Yen's research consistently bridges precision engineering with practical human-centered design, demonstrating a rare versatility that has influenced both clinical robotics and field automation communities.
