Now you can check the position of the trail in your program.
▯ If it is located between –10 and +10 the robot should move straight
ahead (M1 and M2 = left: v = 5)
▯ Between –11 and –40 it should correct slightly to the left
(M1left: v = 5, M2 left: v = 2)
▯ Between +11 and +40 it should correct slightly to the right
(M1left: v = 2, M2 left: v = 5)
▯ At values < –40 it should correct strongly to the left
(M1left: v = 5, M2 right, v = 3)
▯ At values > +40 it should correct strongly to the right
(M1right: v = 3, M2 left, v = 5)
▯ If it looses the trail, it should stop.
You can find the finished program here:
Your robot can now react. However it would be even better if your robot
would turn around at the end of the trail instead of just stopping.
