In order to introduce robots into education field appropriately, it is necessary to consider the children's perceptions of the robots. In this study, the researchers developed the questionnaire for exploring the children's general impressions of the robots, the roles of the robots in the classroom and the appearances of the robots. A hundred and sixty seven fifth-grade children took this questionnaire. The results show that most students have good impressions of the robots and positive attitude to see the robots in their classroom. Their responses also reveal that they might have over expectations of the robots. Besides, the results show that most of children like cartoon character-like robots and animal- like robots, because the robots are very cute.
