Keywords:Humanoid Robot, Uncanny Valley, Face, Robot Anxiety Scale, Cross-cultural Study

In this study, we analyzed the influence of robot anxiety characteristics on the appearance tendency of uncanny valley. We used crowdsourcing for the questionnaire survey of mechano-humanness score (MH score) and likeability of 80 robot face images. Then we divided the participants into two groups according to their scores of Robot Anxiety Scale. The results of t-test of the fitted curves using the MH scores and likeability scores showed that the appearance tendency of the uncanny valley is affected by users’ robot anxiety scale. Those who have less anxiety toward robots showed higher affinity toward the robot faces, while those with high anxiety showed lower affinity toward the same faces.
