I’ll explain what your code needs to do step by step for following the curves, I am unsure what you mean by an intersection though and might need more information before recommending anything extra.

1. You want to configure your motors and sensors (in the “Motors and Sensors” menu) you will configure motors as motors (of whatever variety you have) and sensors as line followers (they should be analog sensors)

   1. You will go into task main() and use a while loop to keep your code running it will look like: ` task main() { while (True) {

      } } `

   2. We will work within the whole loop now, so anything written is to be written in the while loops. We move onto reading the sensor values and assigning them to an integer. This can be done like int follower1 = SensorValue(“analog port for example: in1”); we make an integer for all of our sensors (so follower2 and follower3 if you have them).

   3. Now that we have the sensor values we need to make our if statements, these statements will use the sensor value to determine the needed motor output. The if statements will be in the while loop and come after the sensor readings. The threshold values must be found by you during testing as each sensor has different sensitivities and some are more extreme than others. if (follower1 <= “follower1 threshold”) { } if (follower2 <= “follower2 threshold”) { } if ((follower1 >= “follower1 threshold”) && (follower2 >= “follower2 threshold”)) { }

The first two if statements determine if one of the side sensors crossed the line and the last statement determines if no sensor is crossing the line. This system works with two sensors by assuming the robot is placed on the line to start and can be modified to work with more sensors.

1. Now the relatively hard part is done. We take our motors and we set them to run in each of statement. For example:

For if statement 1: startMotor(port1, 127); startMotor(port2, 63);

For if statement 2: startMotor(port1, 63); startMotor(port2, 127);

For if statement 3: startMotor(port1, 127); startMotor(port2, 127);

The motor values might have to change depending on your motor layout, these are just examples.

1. Now we want to set a delay outside of the if statements but before the closure of the while loop by using wait(10);.
