Claim:
1. A position detection system for detecting a position of an object having a recess or a protrusion, the position detection system comprising: a contactor including an end configured to physically contact, trace and fit with the recess or the protrusion of the object; a sliding mechanism that causes the contactor to slide in two directions perpendicular to each other; a robot configured to cause the contactor to move in a direction perpendicular to a plane defined by the two directions so as to cause the end of the contactor to physically contact, trace and fit with the recess or the protrusion of the object; a camera in a fixed positional relationship to a base of the sliding mechanism and configured to detect a position of the contactor in the plane; and a controller configured to detect the position of the object based on a movement amount of the contactor before and after the contactor slides on the sliding mechanism when the end of the contactor physically traces the recess or the protrusion of the object.
