Abstract
A position correction method includes: a step of opposing a hand to a target by moving the hand such that the hand becomes in a predetermined first initial posture; a first position detection step of detecting a position of the target from a rotation angle of a rotation axis when the target blocks a detection light by swinging the hand; a step of opposing the hand to the target by moving the hand such that the hand becomes a predetermined second initial posture different from the first initial posture; a second position detection step of detecting a position of the target from the rotation angle of the rotation axis when the target blocks the detection light by swinging the hand; and a correction amount arithmetic step of obtaining rotation angle correction amounts of the second axis and the third axis based on a difference between the position of the target acquired in the first initial posture and the position of the target acquired in the second initial posture.
