Relationship Between Mechadroid Type C3 and Human Beings Based on Physiognomic Features

In this paper, we created random facial expressions for the Mechadroid Type C3, a robot equipped with a high degree-of-freedom facial expression mechanism and which is intended to serve a receptionist function. Investigating the morphological characteristics and physiognomy features of these facial expressions, we evaluated what personality characteristics could be expressed by the face of the C3 and what impressions those facial expressions made on people. As a result, it was found that a baby-schema-cute face, modest face, and smiley face are the most suitable as the physiognomy of a reception robot.
