Abstract
Actual environments where people live and do their tasks are not always arranged for robots. When the robots have to execute their task, for example guiding a person to a destination, it uses a database like map, but as the task environment may often change, the database should be maintained simultaneously. This will be a heavy burden for the owner of the robot, so, some autonomous methods like observation learning are required. In this report, we propose an observation and communication method so that a humanoid robot can create and maintain a map for navigation.
