Fire fighters are in danger at large fires and fire in large warehouses. Therefore, development of a compact water discharge robot capable of extinguishing activity is desired. However, existing small water discharge robots cannot lay hoses themselves. In the absence of the ability to lay hoses, it is necessary to pull and extend hoses. In that case the hose is caught the corner when the robot works in a narrow place. For this reason, it is necessary to load hoses on the robot and feed hoses synchronously with the moving speed of the robot. However, since the hose is connected by a fitting, ordinary rollers can’t overcome the fitting. Using a roller and a belt, we fabricated a mechanism to cross the metal fittings. We conducted an experiment to lay fire hose. As a result, we succeeded in laying six fire hoses.
