About

Nobuyuki Otsu is a pioneering figure in intelligent robotics and computer vision, best known for his foundational work on autonomous mobile systems and advanced visual perception. His research spans natural human-robot interaction, real-time object recognition, and haptic exploration for robotic manipulation. Otsu’s most influential contribution is the development of the Jijo-2 mobile robot, an integrated platform capable of natural spoken dialogue for office services—including answering queries, route guidance, and delivery tasks—which has garnered over 60 citations and set a benchmark for socially interactive robots. He also advanced flexible vision systems through the Cubic Higher-order Local Auto-Correlation (CHLAC) approach, enabling simultaneous, real-time recognition of multiple moving objects in surveillance and intelligent transport systems, with key papers accumulating 13 and 7 citations respectively. In robotics, Otsu pioneered haptic detection of object affordances, teaching multi-fingered hands to learn manipulation tasks like unscrewing bottle caps through exploratory touch. His work on classifying motion constraints via compliant hands further demonstrates his commitment to creating adaptive, sensor-driven robots. With a career defined by interdisciplinary innovation, Otsu’s research continues to inspire developments in autonomous systems, human-robot collaboration, and intelligent vision.
