To structure environment in informative way through the sensor network with distributed RFID tags is a promissing approach to an autonomous intelligent robot working in an ordinary environment for daily human life. This paper proposes methods to integrate the data from sensors into online database of the environment and to provide a robot with realtime information of the dynamically changing situation of its surroundings. Based on the analysis of sensor functions and data requirement from the robot, we have designed and implemented a data management system. In the experiments, decision and action of the robots in a task context have been successfully achieved by using the data provided through the data management system.
