  • Publication number: 20240083024
    Abstract: A spring constant correction device and method measure a position and attitude of a distal end of an articulated robot when the articulated robot is operated in a state where elastic deformation is compensated, compare measurement values of the position and attitude of the distal end and target values of the position and attitude, and correct a spring constant based on a result of the comparison. In case of the correction, the spring constant is corrected at a predetermined position based on at least three of: an angle of an end point attitude based on the measured attitude; a torque of the distal end in the end point attitude; an angle of the distal end in a target attitude; and a torque of the distal end in the target attitude. A program of such a method is recorded in a recording medium.
