For current emotional robots, like the panda-type emotional robot, it is necessary to improve the body, diversify the expression and change the emotional expression by adding more degrees of freedom because the expressive movements required for communication are not sufficient. A stable crawler-type moving mechanism is designed to make the panda-type emotional robot possible to perform different actions. The emotional expressions can be adjusted by changing the emotional expression movement based on Laban's theory, controlling the speed of each movement, and changing the movement time. Through the emotion expression experiment, the effectiveness of the robot mechanism and emotional expression system are proven.
