Step 2

Choose "show icon" in the On start brick.

Step 3

Drag if brick into forever brick and judge if both of the line-tracking sensors are detecting the edges of the black line, then set the right wheel speed to 20. If not, set the speed of both wheels as -50 to reverse, pause 300ms and keep the left wheel still but the right wheel moves at a random speed from 50~100 and lasts 100ms. Set the speed of both wheels to 0 and pause 1s to move forward again.
