The present disclosure is to provide a robot control device configured to control a robot. The device controls the robot selectively in a normal operating mode in which the robot is operated within an allowable range defined beforehand according to load applied to the robot and an overdrive mode in which the robot is operated at high speed without operation of the robot being limited to the allowable range. The device operates the robot at high speed in the overdrive mode by interlockingly changing magnification scales of a plurality of parameters defined beforehand that may specify an operating speed of the robot, based on an overdrive magnification scale defined beforehand about a degree of the high-speed operation in the overdrive mode.
