It transmits a laser beam through an optical cable to a robot, which angles lenses and mirrors in the end of its arm to aim the laser towards the parts that need welding.
它通过光导电缆发射激光给机器人，机器人用它手臂末端的角度透镜和镜子对准激光点焊接。

Using a laser, the robot can make highly accurate welds and position itself for each one a lot faster than it could if it were spot-welding in the normal way.
与传统方法相比，利用激光，机器人可以高精度高效率的完成焊接。

The robot "sees" the 3D models of objects based on the laser on its front it uses to scan for things.
