1. A robot system comprising:

  • a first robot having a first robot coordinate system set therein;

    a second robot having a second robot coordinate system set therein;

    a measuring unit including a light-receiving device mounted on selected one of the first robot or an object mounted on the first robot;

    a means for setting the first robot and the second robot at each position of their initial states, respectively;

    a means for detecting, with the light-receiving device, a feature portion mounted on selected one of the second robot or an object mounted on the second robot, and detecting the feature portion imaged on the light-receiving surface of the light-receiving device;

    a means for determining, based on the result of the detection, the distance to be covered by the second robot in such a manner that the two-dimensional feature amount including the position of the feature portion on the light-receiving surface is coincident with a predetermined target value;

    a means for moving the second robot in accordance with the determined distance to be covered by the second robot;

    a means for acquiring and storing the position information of the second robot after movement; and

    a means for calculating the relative positions of the first robot coordinate system and the second robot coordinate system using the position information of the second robot stored for each initial state and the information of the first robot in the initial states in the case where at least three initial states are given.
