-When the right arrow is displayed in the LED matrix, align the two infrared couplers at the bottom and front of the BPI-QCar horizontally and place them directly above the line inspection line,
+When the LED matrix displays the right arrow, place the two infrared tubes of Q-car above the white road around the line.
-Press button B and wait for the calibration procedure to be completed. The left arrow will be displayed on the LED matrix. At this time, the front of BPI-QCar will face the line direction,
+Press button a and wait until the calibration procedure is completed. The LED matrix will display the left arrow. At this time, make the front of Q-car face the line travel direction.
-Press button A, BPI-QCar will start to patrol the line. If the ultrasonic ranging module detects that there is an object with a distance of less than or equal to 10 cm in front of it, it will stop
+Press button B and Q-car will start line patrol driving. During driving, if the ultrasonic ranging module detects an object with a distance of less than or equal to 10cm in front, Q-car will stop.
