In order that people are willing to accept life-support robots in their life, we would like to understand the reason why they refuse such robots. We hypothesize that the refusal is caused by the fear of the robots. To prove this hypothesis, we conduct a questionnaire, lecture, and group discussion to home-economics, science, and robotics students. In the questionnaire, we ask students to estimate the applicability of the robots to various occupations. We guess the over-estimation or under-estimation of the robots’ performances leads to fear. Following the questionnaire, we arrange the group discussion. In this paper, we will report five elements related to the fear of robots that are obtained by the aforementioned activity. These are robots’ appearance, communication ability, human-robot relationship, knowledge of robots, and unfamiliarity with robots.
