A main robot apparatus generates a sound scale command at a command generating state (ST 2 ) to enter into a state of waiting for a reaction of a slave robot apparatus (ST 3 ). When the slave robot apparatus outputs a emotion expressing sound responsive to a sound scale command issued by the main robot apparatus, the main robot apparatus recognizes this emotion expressing sound to output the same emotion expressing sound. In a state of the reaction action (ST 4 ), the main robot apparatus selects an action (NumResponse), depending on the value of the variable NumResponse which has counted the number of times of the reactions to output the action.
