In a Nutshell
When your device won't perform line-following as expected.
It's usually due to Quad RGB Sensor. Do the following steps.
#1 Calibrate the Quad RGB Sensor.
#2 Check if the Sensor is Faulty.
#1 Calibrate the Quad RGB Sensor
This is to make sure the sensor is adapted to your environment.
Factors like light condition and ground color will affect its performance.
Calibrate every time when you change to a new environment is recommended.
During steps 4~5 mentioned above, please check:
If the indicators turn solid on white background, the calibration is OK.
If the indicators keep flashing, please do the calibration again.
#2 Check if the Sensor is Faulty
Move mBot2 to cross a line back and forth by hand and observe.
The indicators should stay solid in the background and turn off on the line.
If not, the sensor is likely to be faulty. Please contact customer support.
#3 Check the Line Following Function
1. Press Home Button on the left side.
2. Check if mBot2 follows the line properly.
