In Robocon, we need a line sensor that able to detect the white lines that overlay on the vinyl flooring that consists of green, blue and red zone. To overcome this problem, green light digital fiber sensor is introduced. With the green emitting light, its reflection on the green, blue and red surface is very low while the reflection to the white white surface is relatively high. Thus, the sensor is able to detect the white lines from the 3 different colors.
