Data from optical sensor
uses sensor bar 10 LED lights (5 of each side)
accurate up to 5 meters triangulation to determine depth distance between two points on image sensor (variable)
distance between LEDs on sensor bar (fixed) roll (with respect to ground) angle can be calculated from angle of
two image sensor points Advantages provides a pointing tool
gives approximate depth Disadvantages line of sight, infrared light problems
only constrained rotation understanding
