This paper presents an upper-body robot system that expresses involuntary abdominal and thoracic (chest) breathing. The system employs servomotors to generate breathing-related movements in both the shoulder and abdominal regions in response to the robot’s breathing parameters. By adjusting the speed, stability, and range of motion of each servomotor, the system aims to enhance nonverbal communication by expressing emotional and physical states such as excitement, anxiety, panic, fatigue, and debility. Experimental results suggest that combining multiple elements of breathing expression can improve the robot’s ability to evoke empathetic responses through emotionally expressive physical behavior.

This paper presents an upper-body robot system that expresses involuntary abdominal and thoracic (chest) breathing. The system employs servomotors to generate breathing-related movements in both the shoulder and abdominal regions in response to the robot’s breathing parameters. By adjusting the speed, stability, and range of motion of each servomotor, the system aims to enhance nonverbal communication by expressing emotional and physical states such as excitement, anxiety, panic, fatigue, and debility. Experimental results suggest that combining multiple elements of breathing expression can improve the robot’s ability to evoke empathetic responses through emotionally expressive physical behavior.
