In this article, the student is introduced to active electro-optical sensors like 2D LiDAR.

Active optical sensors such as 2D LiDAR (Light Detection And Ranging) are used to perform scanning and detection of surfaces surrounding the robot.

These electronic sensors emit light on the horizontal plane, usually the X-Y plane. Based on the captured reflected light, an accurate representation of the distance of the object is known.

A variation of 2D LiDARs, known as 3D LiDARs map the three-dimensional space around the robot. That is, information is captured along X,Y and Z axis.
