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).
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.

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.
Line tracing robots are simply robots with an additional sensor placed on them.
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
You can detect a black line on a white surface using infrared sensors that can distinguish the color contrast between the line and the surface. The sensors can detect the different reflectivity levels of the two colors and help the robot follow the line accordingly. Employing a PID (Proportional Integral Derivative) control algorithm can also assist in keeping the robot aligned with the black line.
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
The Polar robot has multiple sensors, including infrared sensors for detecting obstacles, line-following sensors for tracking lines on the ground, and touch sensors for interacting with the environment. These sensors help the robot navigate its surroundings and perform tasks autonomously.

An IR sensor in a robot can be used for various purposes such as obstacle detection, line following, distance measurement, and object detection. The sensor emits infrared light and detects the reflection to identify the presence or absence of objects in its path, allowing the robot to navigate its environment effectively.
