Basic emotional walking using a biped humanoid robot

In order to explore an issue of human-robot symbiosis, we have constructed a bipedal humanoid robot called WABIAN-RII (WAseda BIpedal humANoid robot-Revised II). The bipedal humanoid robot has a total of forty-three mechanical degrees of freedom (DOF); two six DOF legs, two ten DOF arms, a four DOF neck, four DOF in the eyes and a torso with a three DOF waist. We describe a matter of emotional walking expressions using the bipedal humanoid robot. The emotional walking is created by a set of motion parameters of all its mechanical parts such as the torso, neck, head, arms and legs. The results of the emotional walking expressions are evaluated by the percentage of recognition calculated from the questionnaires, showing that the emotional walking expressions are successfully realized
