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).

no difference between emiter follower and source follower
Across the line starter has a large inrush current.
The advantage of the emitter follower is that it has a positive gain of 1.
emitter follower is a type of negative feedback ,
can be used in a driverless car
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.
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.
it will turn on you.
maybe ask in adifferent way or go to a different site I'm a real person not a machine thank you bye
I have a disadvantage, Uses lots of energy
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.
Advantages of robots are that they can be efficient and cheap. Disadvantages would be they destroy jobs for actual people.
One example might be in a warehouse where the robots follow 'tracks' to and from the shelves they stock and retrieve from.

it blowing up,batery leaks ,malfunctions,rust,and a whole lot more
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.
