Abstract —Great East Japan Earthquake occurred at March 11
2011 and following Tsunami and the Fukushima 1 nuclear disaster
have forced many people to evacuate from their habitations to other
places. These have thrown down many challenges to service robots.
According to a report from Japanese government, about 120,000
people live at evacuated places and 40,000 among them live in
temporary shelters, such as schools or community centers at June 2.
Moving around shelters is one of challenges that robots do services
to people. It is difficult to prepare a complete map of shelters
and to operate robots autonomously at shelters where conditions
dynamically change, and also it is hard to move robots by remote
operation because manpower is needed for other tasks. In this paper,
the experiments of robot operation by elderly and of the proposed
indication method are introduced. We propose a method of indication
to robot and AR marks and QRcode and discuss the merits of the
marks that can be both human and robot readable marks.
