The minimum radius that the robot can follow depends on a combination of
the forward speed of the robot, how quickly the turn drive motor can move the
steering wheel, and how far in front of the robot the light sensor is.We encourage
you to experiment with these variables and see how the robot behaves when fol-
lowing lines with turns of different radius.
Further Optimization of Line Following
You should be happy with this line follower, it runs very smoothly compared to
the differential drive configuration. Nevertheless, you might wonder if there’s
anything you can do to make it run at an even higher speed.
