PURPOSE:To control a photographing car effectively while confirming a remaining running distance by detecting the remaining power of a battery and calculating the running distance and remaining running distance of the battery by a computer from the result of detection. CONSTITUTION:Commanding ratio waves are transmitted from a wireless controlling device 12. The waves are analyzed by a computer installed on the photographing car 1 and an instruction corresponding to the commanding signal is outputted. The power source of a video camera 2 and an illuminating lamp of the car 1 carrying battery 3 is turned on by the instruction to make operations of advancing, retreating and stopping. The number of rotation is detected by a rotational number sensor coupled to a driving motor for running wheel. The remaining power of the battery is detected by a battery sensor, and the running distance and remaining running distance of the battery are calculated by the computer based on the data, and wirelessed from a transmitter to a receiver of a base together with video signals of a camera 2. The running car 1 is controlled while confirming the running distance and remaining running distance through a receiving set. |
