摘要：This study is the design guidelines for the living space with robots. The study can be applied to the architectural planning and focused on the basic environmental primary factor. The authors focused on space size, specifical distance from the wall in the front direction, position, and distance between an individual as factors affecting individual distance. The authors research the distances a small mobile robot moves to a six mats space co.pared with that toward a distances 5 m or more (space less physical factors). The following three results were obtained: (1) The individual distance is smaller than 30 cm in both the approach angle in the experiment space of six mats; (2) The distance from the wall in the front increased, and the individual distance between a participant and a robot also increased; (3) In terms of body position, the upright positioning was clarified and the individual distance was small.
