This study is aimed to develop the function of rescuing the victims under the collapsed buildings, which is added to the hydraulic power shovel for construction. The research theme is divided into two aspects, which are the construction of master-slave controller to dig the debris distinguishing from the victims and the development of "Active Hose" to dive into the debris and supply the fresh water for the life extension.As for the master-slave controller, we proposed "Parallel Impedance Controller" which can realize the actual contact feeling, controller considering the communication time delay, controller adaptable to the impedance change caused by the characteristics of the dug objects, whose validity was experimentally confirmed. And they can lead to the technology of detecting the victims.Active Hose was developed as the artificial elephant's trunk to be added to the shovel. We could succeed in reducing the size to 45mm diameter, which helps to dive into the small space as the debris. The propelling units to push the hose into debris were also developed, and we could experimentally confirm that these hose was useful to supply the fresh water to the victims. In the near future, the dustproof countermeasure will be also done.
