This paper describes the bipedal humanoid robot that makes human laugh with its whole body expression and affect human’s psychological state. In order to realize "Social interaction" between human and robot, the robot has to affect human’s psychological state actively. We focused on "laugh" because it can be thought as a typical example for researching "Social interaction". Looking through a Japanese comedy style called "manzai" or the art of conversation, we picked out several methods for making human laugh. Then we made several skits with the advice of comedians, and made the whole body humanoid robot perform them. Results of experimental evaluation with these skits shows that the robot’s behavior made subjects laugh and change their psychological state seen as a decrease of "Depression" and "Anger".


This study was conducted with the support of the Research Institute for Science and Engineering, Waseda University and as part of the humanoid project at the Humanoid Robotics Institute, Waseda University. It was also supported in part by the MEXT/JSPS KAKENHI Grant No. 25220005; Global COE Program "Global Robot Academia", MEXT, Japan;) Grants for Excellent Graduate Schools, MEXT, Japan; we thank all of them for the financial and technical support provided.
