Abstract:
A robot apparatus whose moving parts are controlled to make the robotic device behave expressively, the device comprising:means for detecting external or internal information; means for acquiring a cause factor influencing the behavior from the external or internal information detected by the information detecting-means; means for acquiring an occurrence tendency of the cause factor-influenced behavior based on the cause factor acquired by the cause factor acquiring means; means for making a comparison among occurrence tendencies of two or more behaviors, acquired by the occurrence tendency acquiring means and belonging to the same group; means for selecting one of the behaviors based on the result of the occurrence tendency comparison made by the occurrence tendency comparing means; and means for controlling the moving parts based on the behavior selected by the behavior selecting means to have the robot apparatus express the selected behavior; wherein the occurrence tendency of the behavior selected by the behavior selecting means being varied adaptively to the cause factor which is variable due to the actual occurrence of the behavior; and wherein a set of behaviors are organized in the form of a hierarchical structure such that a number of low-order behaviors are associated with a high-order behavior.
