Abstract: A joint driving device includes: a reduction gear output shaft that transmits a torque to a second link; a transmission shaft that transmits reaction of the torque to a first link; a transmission shaft outer cylinder arranged on the outer circumference of the transmission shaft and connected to the transmission shaft; a reduction gear output shaft outer cylinder arranged in the outer circumference of the reduction gear output shaft and connected to the reduction gear output shaft; and a wire body arranged between the first link and the second link and including at least one of a wire and a pipe. The transmission shaft includes the motor frame as at least a part. The wire body is housed in a space between the transmission shaft outer cylinder and the transmission shaft, and a space between the reduction gear output shaft outer cylinder and the reduction gear output shaft.

Abstract: An arm drive mechanism which rotates an arm, an angle sensor which detects a rotation angle of the arm drive mechanism and outputs angle information, an angular velocity sensor which is attached to the arm, detects angular velocity acting on the arm and outputs angular velocity information, a control command generating unit which outputs a control command value prescribing a rotational operation of the arm, a gain adjusting unit which incrementally or decrementally changes and thus adjusts a gain of the angular velocity information, and an arm operation control unit which controls an operation of the arm based on the control command value, the angle information and the gain-adjusted angular velocity information, are provided.

Abstract: A method of controlling a robot includes the steps of calculating a torsional angular velocity of an arm using a difference between an angular velocity detected by a gyro sensor and an angular velocity in a gyro sensor coordinate obtained from information detected by a first encoder and a second encoder, calculating a correction amount of a sensitivity error of the gyro sensor using a variation in the torsional angular velocity, and correcting sensitivity of the gyro sensor using the correction amount of the sensitivity error.
