Abstract:
A substrate transporting apparatus includes a first light emitting sensor emitting a first sensing light in a first direction, a first light receiving sensor receiving the first sensing light, a second light emitting sensor emitting a second sensing light in a second direction different than the first direction, a second light receiving sensor receiving the second sensing light, a substrate transporting loader passing through traveling lines of the first sensing light and the second sensing light, a state information storage unit storing state information of the substrate transporting loader, and an operation information computing unit computing operation information of the substrate transporting loader based on the state information.
