Ethologically inspired human-robot communication has been studied to realize long-term social relationships between a robot and persons. Specifically, dogs' attachment behavior is applied to the robot. This paper presents an approach to behavioral characteristic of the robot's attachment behavior. The behavioral characteristic is determined by three factors. In the previous model, the factors of the behavioral characteristic are given as fixed numerical values. Therefore, the behavioral characteristic of the robot would not change even if the robot has experiences of interactions with persons. To develop social relationships between the robot and a person, it is more natural that the robot behavioral characteristic is changed based on the interaction history. In this paper, persons' behaviors during interaction and processes of robot behaviors are evaluated and the factors of behavioral characteristic are updated. We evaluate the proposed method to update the behavioral characteristic through experiments.
