Robot Differential Behavioral Expression in Different Scenarios.

During human-robot interaction, a robot is commonly considered dull since it follows very limited programmed orders repeatedly. Although faced with different people in different scenarios, a robot behaves the same. In this paper, we aim to construct a robot emotion system with respect to the personality of the robot and the reaction of the interactor. The robot's behaviors, including its facial expression, voice, and motion, are all parameterized and interrelated with the robot's emotions. In this way, the robot will perform much richer behavioral expressions in different situations. Two typical experiments are conducted, where the robot acts as a guard at a school gate and a study partner in a house, respectively. According to the questionnaire, most of the participants agree that the robot behaves differently in the two scenes.
