It always need a path to run either white or else since the IR rays should reflect from the particular path (color mostly used white on black).
fingers not alou9 2 go near line ben9ers because its really its really hot an9 u might get burnt
You usually have a light source shining on the ground, and a light sensor detecting the reflected light. It then calculates where the lightest parts are (assuming it's a white line on a black background) and adjusts its route accordingly.
Single sine diagram is graphical representation of electrical circuit drawn using single line instead of drawing 3 separate lines for three phases.

Line tracing robots are simply robots with an additional sensor placed on them.
The robot has sensors in its base that detect to difference in brightness between the white surface and the black line. It is programmed to stay on the black line by computer software.
a line following robot follows a black line about 3/4 inches in width on a black surface. these robots are usually used in compititions. according to rules, the robots are raced one at a time and the robot with the shortest time wins. the curves in the lines must be 4 inchces or more in diameter
It sounds like you are using an NXT unit, but to make a line follower, you don't find the distance between the robot and the line, you find the line and center it under you. I would recommend using the light sensor because it will allow you to find the area where the line is darker than the surrounding surface. Then, whenever the line is not centered under your robot, you have it go back and forth until it finds it.
Off-line Programming (OLP) is a Robot programming method where the Robot Program is created independent from the actual robot cell. The robot program is then uploaded to the real robot for execution. In off line programming the robot cell is commonly represented as a graphical 3Dmodel.
In the future, a line following robot could be used to lay groundwork for a small structure, repaint objects such as baseball diamonds, lay a trail of something down, or even plow the ground for farmers.
For repetitive tasks which use the same path things like following one on the floor of a factory to remove the need for a human operator also lines of metal placed under lawns can be used as a guide for a robot lawnmower
Andrew Charles Boud has written: 'The development of an off-line robot programming method using virtual reality'
Some popular reference books for building line following robots include "Robot Building for Beginners" by David Cook and "Make: Sensors: A Hands-On Primer for Monitoring the Real World with Arduino and Raspberry Pi" by Tero Karvinen and Kimmo Karvinen. Websites like Adafruit, SparkFun, and RobotShop also offer tutorials and resources for building line following robots.
can be used in a driverless car
One example might be in a warehouse where the robots follow 'tracks' to and from the shelves they stock and retrieve from.
