Abstract
This paper presents the UX process "Three step Sustainable-model" for social robots to be sustainable in society. “Sustainable social robots” means that the social robots have roles in the society and the resources to play the roles for the social robots are kept in the society. The UX process is the process for human experiences of interaction with social robots. For social robots to get positions in society, they need not only functions and performances but also well grand-designed social environments. To investigate the method of grand design, in the paper three fieldworks using social robots have analyzed. As a result, "Three step Sustanable-Model" is proposed. This model is a hypothesis at present, but useful for social robots to be sustainable in society.
