Facial expression on robot SHFR-III based on head-neck coordination

As nearly 55% of information is transferred by facial expressions, facial expression robot take an important role in human-robot interaction. This paper introduces the development and experiments of facial expression robot SHFR-III. The robot´s facial system is consist of eyebrow mechanism, eyeball mechanism, lid mechanism and jaw mechanism. Neck mechanism and its kinematic analysis is also done to make robot´s expression more vivid. Experiment based on head-neck coordination and motion joining is also presented. Last, summary and further research plan are attached.
