Abstract
A transfer system includes a hand that supports a workpiece to be transported; an arm that moves the hand; a scanning controller that moves the hand by the arm along a scanning direction that intersects sides which are provided to be fixed to the hand and not parallel with each other, such that the sides pass a known reference position in a transfer path of the workpiece; and a position detector that detects a positional deviation of the hand in a direction intersecting the scanning direction, based on a timing at which one of the side reaches the reference position and a timing at which the other side reaches the reference position RP, while the scanning controller is moving the hand.
