Social behavioral robot that stands in line

摘要

Recent research results on mobile robot navigation systems make them seem promising for utilization in service fields, but in order to utilize the robot in a peopled environment, it should recognize and obey the people's social behavior. In this paper, we propose a social behavioral robot that stands in line as people do. We have employed the notion of personal space for modeling a line of people and developed a stereo vision system to recognize them. We have also developed a mobile robot navigation system that can purchase a cup of coffee even if people are waiting for service in line.
