%0 Journal Article %T Humanoid Robot Head Design Based on Uncanny Valley and FACS %A Jizheng Yan %A Zhiliang Wang %A Yan Yan %J Journal of Robotics %D 2014 %I Hindawi Publishing Corporation %R 10.1155/2014/208924 %X Emotional robots are always the focus of artificial intelligence (AI), and intelligent control of robot facial expression is a hot research topic. This paper focuses on the design of humanoid robot head, which is divided into three steps to achieve. The first step is to solve the uncanny valley about humanoid robot, to find and avoid the relationship between human being and robot; the second step is to solve the association between human face and robot head; compared with human being and robots, we analyze the similarities and differences and explore the same basis and mechanisms between robot and human analyzing the Facial Action Coding System (FACS), which guides us to achieve humanoid expressions. On the basis of the previous two steps, the third step is to construct a robot head; through a series of experiments we test the robot head, which could show some humanoid expressions; through human-robot interaction, we find people are surprised by the robot head expression and feel happy. 1. Introduction Robots play an increasingly important role in our life and work, to assist and even replace the human work in more and more fields. With the development of society, the traditional robots canĄ¯t meet human beings, humanoid robots [1¨C3] are coming, and human beings want more and more analogue. There are many famous humanoid robots, for instance, Kismet and Leonardo made from MIT in USA, ROMAN made in Germany, and WE-robot and SAYA made in Japan, which all could surprise people and give some kind of special feelings but cannot gain some place in personĄ¯s awareness. This paper divided these humanoid robots into two domains. First like a beautiful flower vase to people, human beings find it is an amazing thing, and only like to see its actions, for instance, smile, anger; these robots are almost made in Japan and have shocking appearance; second like a toy to people, we find it interesting to play with this kind of robots, which can show some facial expressions, and these robots are always made in USA and Europe. In order to avoid these cases and simplify the whole design, this paper is meant to make a humanoid robot head instead of the whole body, which not only has good appearance, but also can show some expressions. The paper is organized as follows: in Section 1 we introduce two kinds of humanoid robots. In Section 2 we introduce the concept of the uncanny valley. In Section 3 we talk about the Facial Action Coding System (FACS). In Section 4 we design the hardware and software of the robot head and build the robot head according to the previous design. %U http://www.hindawi.com/journals/jr/2014/208924/
