Abstract
A method of operating a transport system includes detecting an anomalous condition of a wafer transfer vehicle; sending the wafer transfer vehicle along a rail to a diagnosis station adjacent to the rail; and inspecting properties of the wafer transfer vehicle, such as a speed, a weight, an audio frequency, a noise level, a temperature, and an image of the wafer transfer vehicle, by using the diagnosis station.
