About

Ho Yeong Khing is a pioneer in mobile robotics perception, whose work has fundamentally shaped how autonomous systems interpret their environments. His primary research areas include multi-sensor data fusion, ultrasonic sensing, and laser-based localization for mobile robots operating in complex, cluttered indoor spaces. Khing’s most influential contribution, "Multi-ultrasonic sensor fusion for mobile robots" (2002), with 48 citations, addresses the critical challenge of overcoming specular reflection uncertainties in ultrasonic sensors. By developing both accurate sensor models and robust fusion methodologies, he enabled robots to extract reliable range information from noisy, multi-sensory inputs—a foundational step for safe autonomous navigation. In his complementary work, "The localization of mobile robot based on laser scanner" (2002), Khing introduced a landmark recognition technique using break-point detection in laser scanner data, achieving precise localization without pre-mapped environments. This natural landmark approach remains a cornerstone for modern SLAM systems. Through these contributions, Khing demonstrated that combining complementary sensor modalities—ultrasonic for proximity and laser for structure—could dramatically improve a robot’s spatial awareness. His research continues to inspire engineers building perception systems for service robots, warehouse automation, and autonomous vehicles.
