In this study, we analyzed what kind of animal-like qualities are important in the acceptance of partner robots in households. The questionnaire surveyed the animal-like qualities of visual, auditory and tactile elements, and analyzed the relation between the partial animal-like qualities of each element and the duration of use. We also showed what aspects of the robot’s animal-like nature the user perceived by analyzing the relationship between the animal-like nature of each element of the robot and the sense of living things.
The results suggest that items such as the intelligence of the robot and the animal-like shape of the robot might be factors in acceptance. It was also suggested that the smoothness of the robot’s movement and the animal-like sound of the volume other than the robot’s voice were factors that made users feel a sense of living-likeness toward the robot.
