In this paper, we propose an information assistance
system for victim search in rescue activity. This system
is composed of an intelligent data carrier for rescue
(IDC-R) and a data retrieval blimp (DRB). An
IDC system enables to provide the environment with
information storage, sensing, and processing functionality.
We have incorporated the auditory functionality
into IDC units and applied them to rescue
activity support. IDC-Rs attached in buildings repeat
calling to victims and recording their answers
independently. A DRB flies over a suffered area and
communicates IDC-Rs to activate them and to obtain
data. We have implemented actual devices and
describe a feasible motion planning algorithm for a
DRB.
