<p>The physical appearance of a robot can significantly affect interactions between humans and robots. Consequently, it is imperative to elucidate the visual factors that affect these interactions. This study aimed to ascertain the influence of a robot’s physical attractiveness by investigating whether an attractive robot is preferred and whether it creates a positive impression in a communication context. Two groups of stimuli were used in the experiment: one consisted of attractive and non-attractive robots. In Study 1, 567 adult men and women participated in an online survey. The results revealed a significant preference for the attractive robot group in the communication situations. In Study 2, 931 adult men and women participated in an online survey, and the findings indicated that attractive robots received more favorable ratings in terms of human- and communication-related attributes. This study substantiates the significance of physical attractiveness in the context of human–robot interactions. This underscores the need to deliberate upon and study the phenomenon of beauty bias within the field of human–robot interaction.</p>
