Following a Line Using Two Light Sensors

The video at this site demonstrated how to get a robot to follow a line using a single sensor. You have likely seen that this method of following a line has several limitations. Certainly you could enhance your programming to use different strategies to improve how well the robot follows the line with a single sensor, but you might also want to consider adding a second light sensor.

Following are pages at other sites with ideas on how to improve your line follower:

One and two sensor line following

"Toeing the Line" - a report by a 9th grader on multiple line following techniques

More advanced strategies with one light sensor and an NXT

AND, you can use three sensors - so what would you do differently if you were using THREE light sensors???
