About

Tsutomu Sawada is a pioneering researcher in the field of affective robotics, with a primary focus on emotionally grounded architectures for humanoid robots. His most significant contribution is the development of the Emotionally Grounded (EGO) architecture, which enables autonomous robots to select behaviors and modulate motions based on internal emotional states and homeostasis. This work, demonstrated on Sony’s QRIO SDR-4X II humanoid robot, has garnered 37 citations and represents a foundational approach to integrating emotion into robotic decision-making. Sawada further advanced this framework by introducing algorithms for learning behavior selection through interaction, where behavior values are shaped by external stimuli and internal drives. His research on associated emotion and its expression in entertainment robots (22 citations) has been instrumental in creating more believable and engaging robotic companions. By grounding robot behavior in emotional states rather than purely logical rules, Sawada’s work has influenced the design of socially interactive robots, bridging the gap between artificial intelligence and human-like emotional expression. His contributions remain highly relevant for researchers in human-robot interaction and affective computing.
