Question 3: Why the smart robot cannot perform infrared obstacle avoidance?   
Answer: Firstly, you should check the whether the infrared detection module on the 
smart robot works properly.  When there is  no obstacle  ahead of the robot, the 
green LEDs on the robot are off. When the obstacle is detected, the green LEDs will 
light up. In case that the LEDs are always off or always on, you can try to adjusted 
the potentiometers on the bottom of the robot to make the LEDs work properly. 
Question 4: What can I do, if the motion of the smart robot is wrong? 
Answer: In case that the direction of motion is wrong, you may need to change the 
pin settings in your program. 
Question 5: The rotational range of the steer is abnormal.   
Answer: The rotational range of the steer can reach 180 degree. In normal condition, 
the steer can turn to left at 90 degree, and turn to right at 90 degree as well. If there 
is a big difference between the both sides, you should reassemble the steer and 
make adjustment.
