Is it possible to implement a distance meter (rangefinder) using a webcam and the laser spot module? If so, can you please give me some indications on how to do that?

You can read more about the math at


but basically if you angle the laser down from the top of the robot then the spot height will relate to the distance that the spot is illuminating.
