PURPOSE:To improve the operation efficiency of an unmanned cart by charging a battery through a charger by the power of a ground power unit during robot work by power supply from the ground power unit on a working station. CONSTITUTION:When an unmanned cart 10 reaches a predetermined working station 60 and is positioned, an industrial robot 40 is supplied with power and pressure air through an electric connector 74 held on a support plate 72 and a counter 7b for air when the movable support plate 72 is connected to power supply terminals 64 and pressure air supply terminals 66 in a supply terminal 62 on the working station 60 side. In this case, power received from a movable connector 32 is fed in parallel to a charger, and a battery is charged. According, the unmanned cart can be operated at high efficiency. |
