Today, various types of “personal robot” are beiug develeped for general users. The research scope of the robot engineering needs to cover cultural sciences such as socialsciences, clinical psychology, philosophy, cognitive science, etc. At the same time, a greater emphasis should be given on exploration into human-related factors, such as image recognition/understanding, psychological effects, unconscious perception in light of communication or interaction between humans and personal robots. We participated in the Robofesta Kanagawa 2001 Yokohama, and conducted surveys on human-related factors involved in communication with robots. We used questionnaire sheets, drawings, observation and questioning as the main survey tool to gather information fromvisitors. It was expected that we could collect as large information as possible both in data type and quantity because audience from various backgrounds and different age groups would visit the show. Surveyed data were analyzed in many different angles. In this paper, we will discuss advantages of surveys conducted in an exhibition as well as findings obtained from the analyzed data of our surveys.
