- We are conducting research and development in technology for unifying the information of a large number of intelligent sensors distributed in a disaster-stricken area. Operating effectively as a system in real time, network household electric appliances, a personal digital assistant (PDA), a robot, etc. provided information and an action plan for a stricken area’s situation. In this paper we introduce ubiquitous device "Intelligent Data Carriers for Rescue (IDC-R) " and formation of a dynamic network, and development of a means of disaster information communication (a group of people, a robot, an adhoc network, a home network, etc.). Target experiment for actual proof is also introduced.
