This paper discusses the familiarity of a koala style robot. The familiarity is very important for communicating with robot to human. In this research, we are developing koala style robot by using various sensors to take various cute motions. The developed koala robot has 14 degree of freedom and has 7 different type sensors. We developed various motions to feel familiarity with koala robot. As an experiment, we have a questionnaire to evaluate the relation between familiarity emotions and motions of koala robot.
