If the left Line Tracking Sensor sees dark, what should the robot do?

When the left Line Tracking Sensor detects a dark surface, it typically indicates that the robot is positioned off the designated line it is meant to follow. The purpose of the left Line Tracking Sensor is to help the robot remain aligned with its path. If this sensor sees dark, it generally means the robot has strayed slightly to the left of the line.

In response, turning right helps the robot correct its position and get back onto the line. This maneuver allows it to realign with its intended path. The robot relies on the feedback from its sensors to make navigational decisions, and responding by turning in the correct direction ensures it can continue to follow the line effectively.

Other actions, such as maintaining the current path or stopping immediately, do not effectively address the misalignment caused by the sensor detecting dark. Maintaining the current path would allow the robot to stray further away from the line, while stopping would not resolve the issue of its position relative to the intended path.
