    摘要: The present invention belongs to the field of techniques related to a laser robot and a method of controlling the same, particularly for performing weaving of a laser beam easily with high accuracy without the provision of a vibrating condenser lens at the leading edge of an arm.To solve the problems, in the laser robot (RB) of the present invention, a first inclined mirror (41a) is mounted on a motor (42a) inclined at a predetermined angle from a plane perpendicular to the direction of the rotation axis of a rotor shaft. Similarly, a second inclined mirror (41b) is mounted on a motor (42b) inclined at a predetermined angle. The laser beam (LB) emitted from a laser oscillator (8) is reflected in series by the first and second inclined mirrors (41a, 41b) and is subsequently propagated in the laser robot (RB) to be directed toward workpieces from the tip of a torch (7). By controlling the numbers of rotations, rotation directions and rotation phases of the first and second inclined mirrors (41a, 41b), weaving modes of the laser beam (LB) are selected.
