Abstract: A logistic station comprises a plurality of objects having a first status and a second status and a detection device used for detecting the status of the objects. The detection device comprises a pallet having a plurality of first supporting portions and a first sensor. The objects are detachably disposed on the first supporting portions of the pallet. A first reference position and a first predetermined position are configured in the pallet with respect to the first supporting portions thereof. The first sensor transmits a first signal to the first predetermined position to detect whether objects having the second status.

Abstract: A displaced wafer detection system comprises a unified pod, a pod opener, a horizontal transmission robot, and a sensor. The unified pod encloses a plurality of wafers in a first position. The pod opener opens the unified pod. The horizontal transmission robot carries the wafers from the unified pod to a second position. When one of the wafers reaches the second position, the sensor detects if any wafer slips during wafer transmission from the unified pod.
