Why the Line Follower Mode doesn't work on mBot
When mBot works properly with Manual mode and Wall avoidance mode but doesn’t work
properly with Line follower mode, please test if the line follower sensor is faulty referring to the
below steps.
Step 1
Put the two sensors of the Me Line follower above (Detection range: 1~2cm) a white desk or
white paper and check if the two LEDs corresponding to the two sensors lit up?
Step 2
Move it away from the white desk or white paper and check if the two LEDs corresponding to the
two sensors turn off?
