  • Patent number: 11400606
    Abstract: An articulated robot has an arm, a drive motor for driving and positioning the arm, a gas spring for supporting a load acting on the arm to reduce a load of the drive motor and a control unit for controlling the drive motor. The control unit has a function of estimating a decrease state of a gas sealed inside the gas spring based on an actual current value of the drive motor obtained at a stop position at which the drive motor is operated and stopped in an energized state. The decrease state of the gas sealed inside the gas spring is estimated based on the current value of a servo motor without causing decline in operation rate of the robot.
