<p>A height sensor (13) is fitted to a fitting blank (14) in such a manner that it is substantially in close contact with, and parallel with, a laser machining head (9). Three-dimensional distance data between a laser emission port (9a) of the machining head (9) and a measurement edge (13a) of the height sensor (13) is stored in advance in a robot controller (10). A longitudinal distance of a laser machining start point is measured automatically and directly from above on the basis of this distance data, and the longitudinal distance of the laser emission port (9a) of the machining head (9) is corrected. Accordingly, a laser robot of the invention can execute laser machining while measuring highly accurately correction data of the height distance when the machining head is positioned to the laser machining start point.</p> |
