Abstract
A robot that attaches and removes a work with respect to a machining device is controlled to correct a deviation of the robot's posture. A robot control device includes a correcting part that corrects a posture of the robot based on a measured value of a sensor that measures a load on the robot; a robot posture obtaining part; a work attachment target posture generating part; and a path generating part. The correcting part corrects the posture of the robot to decrease the load on the robot to be smaller than a threshold when the robot grips the work after machining. The robot posture obtaining part obtains a removal posture that is the posture of the robot after the correction for a plurality of the works after machining. The work attachment target posture generating part generates a new work attachment target posture based on a plurality of the removal postures.
