摘　　要：In robotics and human-robot interaction,a robot’s capacity to express and react correctly to human emotions is essential.A significant aspect of the capability involves controlling the robotic facial skin actuators in a way that resonates with human emotions.This research focuses on human anthropometric theories to design and control robotic facial actuators,addressing the limitations of existing approaches in expressing emotions naturally and accurately.The facial landmarks are extracted to determine the anthropometric indicators for designing the robot head and is employed to the displacement of these points to calculate emotional values using Fuzzy C-Mean(FCM).The rotating angles of skin actuators are required to account for the smaller emotions,which enhance the robot’s ability to perform emotions in reality.In addition,this study contributes a novel approach based on facial anthropometric indicators to tailor emotional expressions to diverse human characteristics,ensuring more personalized and intuitive interactions.The results demonstrated howfuzzy logic can be employed to improve a robot’s ability to express emotions,which are digitized into fuzzy values.This is also the contribution of the research,which laid the groundwork for robots that can interact with humans more intuitively and empathetically.The performed experiments demonstrated that the suitability of proposed models to conduct tasks related to human emotions with the accuracy of emotional value determination and motor angles is 0.96 and 0.97,respectively.
