    • PROBLEM TO BE SOLVED: To highly accurately control the position and attitude of a robot. SOLUTION: In the robot controlled in accordance with a coordinate relation between a signal value outputted by an encoder, a previously prepared signal value and a joint angle, an orthogonal coordinate system is defined so that a first axis corresponds to a central line of rotation of a link. On the robot located at a distance D S spaced from an origin of the coordinate system, a sensor for detecting a position variation in a direction of a second axis is attached. The link is rotated by an arbitrary angle with respect to the second axis as a reference, and then, a signal value E A of the encoder is obtained. The link is rotated to one side by an angle β. Then, the link is rotated by an angle -2β to obtain a position variation ΔP S detected by the sensor from the start to the end of the rotation of the angle -2β. Based on the position variation ΔP S , the distance D S and the angle β, an actual angle α of the arbitrary angle is calculated. The angle α is converted into a joint angle θ α . The coordinate relation between the signal value and the joint angle is corrected so that the previously obtained signal value E A and the joint angle θ α have a coordinate relation.
