The obiective of this thesis is to suggest a design guideline for a teaching assistant robot by clarifying what images satisfy the role ofa teaching assistant robot, and by finding out what elements of body feature pitomize such irnages. Images ofteaching assistant robots were established from a literature review and factor analysis. And eight elements of bedy feature were extracted from human form. Robotic external form samples varied according to the elements of body feature, which was modeled three-dimensionally. Children, who are the main users of teaching assistant robots, evaluated the 3D robot samples prejected onto a wall in real size. The evaluation criteria were the role images of teaching assistant robots, demographic features about age and gender, preference, and appropriateness. The results of evaluation were analyzed by ana]ysis of variance, and aBalysis of correlation. Finally, a design guideline for a teaching assistant robot was suggested based on the results of the experiment about the correlation between elements ofbody feature and role images.
