Initial Study on Robot Emotional Expression Using Manpu

Abstract

In recent years, robots have started to play an active role in various places in society. The ability of robots not only to convey information but also to interact emotionally, is necessary to realize a human-robot symbiotic society. Many studies have been conducted on the emotional expression of robots. However, as robots come in a wide variety of designs, it is difficult to construct a generic expression method, and some robots are not equipped with expression devices such as faces or displays. To address these problems, this research aims to develop technology that enables robots to express emotions, using Manpu (a symbolic method used in comic books, expressing not only the emotions of humans and animals but also the states of objects) and mixed reality technology. As the first step of the research, we categorize manpu and use large language models to generate manpu expressions according to the dialogue information.
