Abstract:
1. A robot system comprising: a first movable component on which a first mark is provided, the first movable component being moved by a first actuator; a second movable component on which a second mark is provided, the second movable component being moved by a second actuator; a control unit that controls the first and second actuators to respectively move the first and second movable components in a three-dimensional coordinate system based on control information; a camera that takes an image of the first and second marks so as to output image data when the first and second marks are located at different positions; and a calibrator that creates a transformation parameter for correlating a two-dimensional coordinate system of the image data with the three-dimensional coordinate system based on the image data and the control information, wherein the control unit causes the first and second movable components to perform manipulations of moving a work piece.
