Abstract:

Our research goal was to develop a face robot that has a human appearance and can display facial expressions. We also constructed facial expression recognition with vision in order to create human－robot interaction.

To display facial expressions, we used fishing line and fishing net to produce a muscular structure similar to the linear and nonlinear muscles of the human face. We also designed a mechanism for producing tears and made the face robot cry like a human being. For facial expression recognition, we used a few mouth and eyebrow descriptors by which to identify facial expressions. The results proved that a few descriptors could be used to achieve a high recognition ability. Finally, we combined facial expression display with facial expression recognition, and designed some conditions for human－robot interactions. We thus produced a closer and more natural relationship between humans and robots.
