The purpose of this study is to clarify the avoiding space between the human and the robot. In the experiment, the avoiding distance between the human and the robot was measured, while a man tried to avoid interplaying with the independently-moving robot. The characteristics of human movements were verified from results. According to the results, a sight distance does not differ between male and female when avoiding the specific robot we used in this study. It has also proved that there is no difference in a sight distance by interlacing angle. The study showed that the sight distance expands spherically with aradius of 1450(mm) from the height of the robot's eye. The avoiding distance from side ways was calculated to be 610(mm), which is smaller than that of human to human. This value suggests that it requires about 1100(mm) passing by one another, and it is narrow in current housing plans.
