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.
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.
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.
The vacuum robot cleans your floor like a regular vacuum. But the robot vacuum does it by a press of as button. You don't even have to do it yourself, it makes one job less that you have to do.
The shape of a robot's body is typically determined by its function and design requirements. Factors such as the tasks it needs to perform, the environment it will operate in, and the components it needs to accommodate influence the shape of the robot's body. Additionally, considerations such as mobility, stability, and ergonomics also play a role in determining the design of a robot's body.
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.
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 must be talking about "follow" mode. When one robot follows the other the program must prevent the following robot from detecting the followed robot until it has moved a minimum predefined distance that is adjusted to prevent it from colliding with, or losing track of, the robot or whatever its following.

One risks of a robot is following the robot it can lead to a dangerous place
By following their programing.
Light, temperature, sound, you, and darkness
I actually use NXT but I imagine you use the light sensor to detect when there isn't a black line under it. Then steer to the left a bit and if the line isn't found, steer to the right until it's found.
Robot sensors detect different things and send different amounts of electricity to the Robot's controller board to tell their findings. Then the controller board uses these different amounts of electricity to interact with its surroundings. Example: Lets say you have a robot that is made to follow light. Lets say your robot has 3 light sensors. One in the front of your robot one on the right and one on the left side. The sensors will detect how much light is on the front, right, and left sides and send this data to the controller board. Then the controller board uses this data to tell the robot with direction to go.
For the newest kind of robot, the light sensor is used to detect the white lines from the dark lines on the nxt this helps your robot follow the lines!!

One can find a tutorial on how to build a robot from the following sources: Multiplo Talk, Society of Robots, Instructables, Robot Shop, Lets Make Robots, to name a few.
Robot is the culture of making a lot of bleeping and blooping noises, while move choppily and following commands.
