Device and method for calibrating a robot
 A calibrating device is composed of a movable portion having a degree of freedom movable in three axis directions orthogonal to each other, a displacement detector for detecting displacement of said movable portion as per degree of freedom, a universal joint having a three-axis rotating degree of freedom, which is attached to the tip end portion of said movable portion, a fixture attached to a free end of the universal joint, which is capable of being easily connected to the tip end portion of the wrist of the robot. The calibrating device measures displacement of the wrist tip end portion. That is, the invention provides a comparatively simple calibrating device and a calibrating method, in which automation is easy without requiring any complicated operations, using the calibrating device.
