Can the Movements of Robots Convey Emotions to People? The Robots Communicate with Human and Express Emotions through Different Actions

The service robots as a fast-growing industry in today's society, have gained the attention of all the countries. The research of service robots has gradually shifted from functional to perceptual. During the human robot interaction, in addition to the voice interaction, movements are also an important factor in expressing information and conveying emotions. Through observation, this study collected the actions from three industry fields which have a total of 22 experts and staffs, and also analyzed and classified these movements. Finally, it established the robotic actions of animation for testing and using the three kinds of vocabulary of the robot personality traits (F1. “active factor”, F2. “helpful factor”, F3. “dominant interaction factor”) as the evaluation criteria of perception, explored the user cognition to the different personality traits of robots. The results show that the robot movements have the greatest impact on the first type of F1 ⌊ active factor ⌋, while the industry category only affects the third type of F3 ⌊ dominant interaction factor ⌋. In the case of different industry categories, the impact of F1 ⌊ active factor ⌋ is also different. For overall preference, every action will increase users' preference. However, in terms of acceptance, “actions with information transfer functions” can increase users' acceptance, but” auxiliary Action” will not improve them. The results of this study can propose action design guidelines for personalized service robots for different industries.
