About

Hirotaka Imagawa is a leading researcher in humanoid robotics, with a primary focus on enabling robots to learn from and anticipate human motion. His work bridges the gap between raw sensory data and high-level symbolic reasoning, allowing robots to interact more naturally and intelligently with people. A key contribution is his pioneering approach to the online acquisition and visualization of motion primitives, where humanoid robots incrementally learn full-body movements directly from observing a human demonstrator in a motion capture studio, as detailed in his 2009 paper (15 citations). This work laid the foundation for more adaptive robotic learning. Building on this, Imagawa developed a groundbreaking system for predictive human-robot interaction. His 2011 paper (13 citations) introduced the "motion symbol tree" and "motion symbol graph," a symbolic inference framework that enables a humanoid robot to not only recognize current human behaviors but also predict future actions. By structuring motion patterns as symbolic representations, his research provides a powerful method for robots to anticipate and proactively assist humans, marking a significant step toward truly collaborative autonomous systems.
