Research Summary

Wataru Sato (Ph.D.)

We conduct research to elucidate the computational mechanisms of human mind (emotions, cognition, and behavior) to develop robots with mind.

Specifically, we conduct the following research.

  • Computational elucidation of human mind; its implementation in robots collaborating with engineers.
  • Psychological evaluation of robots' functions.
  • Interdisciplinary research across psychology, informatics, and robotics, especially on emotional communication.
