What invalid assumption could be made about the functionality of Line Tracking Sensors?

The assumption that Line Tracking Sensors will always detect the line perfectly is invalid because it overlooks various factors that can affect sensor performance. Line Tracking Sensors rely on contrasting colors and reflectivity to determine the presence of a line. Environmental conditions such as lighting, the surface texture of the floor, and even wear on the sensors can lead to inconsistencies in detection. Additionally, if the line is too narrow or the sensor is not correctly positioned, the sensors may fail to read the line reliably. Thus, while they are designed to track lines effectively under optimal conditions, perfect detection cannot be guaranteed in all situations.
