Abstract
Robots have played mainly important roles in factries up to the present and will be active in our daily life in future in a house. These are home robots or service robots. In order to cooperate with human being, these robots must act with fertile emotions. In order to clarify the actions with emotion, the actions of a Bunraku puppet were analyzed. Bunraku is a classical puppet entertainment in Japan. In this show, the puppets express the exaggerated human actions with fertile emotions. In this analysis, the puppet actions are modeled by stochastic processes. We present a hypothesis that “the action is decomposed into three factors: (1) the functional factor, (2) the emotional factor and (3) the stochastic factor”. We measured the real actions of a Bunraku puppet and obtained the experimental data (time series). From these time series, the above three factors were computed, based on the above hypothesis. In order to examine the validity of the above computation (signal processing), the power spectra of the stochastic factors were analyzed.
