DEVICE AND METHOD FOR CALIBRATING ROBOT

摘要

A calibrating device 2 is composed of a movable portion having a degree of freedom movable in three axis directions orthogonal to each other, displacement detecting means (212, 222, and 232) for detecting displacement of said movable portion as per degree of freedom, a universal joint (25) having a three-axis rotating degree of freedom, which is attached to the tip end portion of said movable portion, a fixture (26) attached to a free end of the universal joint (25), which is capable of being easily connected to the tip end portion (16) of the wrist of the robot. The calibrating device (2) measures displacement of the wrist tip end portion (16). 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. <IMAGE>
