Abstract
A controller: selects one optical sensor to use from among a first optical sensor and at least one second optical sensor; moves a substrate transfer hand to a detection start position at which an optical path of the selected optical sensor is positioned above a substrate placing portion and does not interfere with a pillar portion; lowers the substrate transfer hand from the detection start position to a detection position at which an object is detected by the optical sensor; and stores, as a height position of the substrate placing portion, a height of the optical path of the optical sensor from a predetermined positional reference when the substrate transfer hand is at the detection position.
