When a disaster happens in an area where people live in and there are victims at there, a rescue team is organized and sent to save the victims. Traditionally, the rescue parties run a risk of their own lives to save the victims. We believe that recent progress of robotics technologies and networking technologies can help the situation. We propose the idea of the autonomous network construction system and the remote investigation system of the disaster area by robots. We defined such a network as Robohoc network in our previous paper. In this paper, we propose one of the design ideas that suits the Robohoc network requirements defined in.
