Rescue Robot Day 2Exploring Computer Science

Lesson 6-11

Step 1 - Line Following• There is a line following tutorial in the Common section, but

it might not work for your robot and this course!• If your robot is going in circles then go to the view programs and

check the light sensor on the white and on the line. Adjust the light sensor condition in your code to match what you see.• If your robot is getting lost on the turns then you can:

1. Adjust the speed. Slow it down2. Rather than running one wheel forward and stopping the other wheel,

have the one wheel move forward and the other wheel move backward (at about ½ the speed)

Step 2 – Finding the Victims• You will need to decide whether to use the Ultrasonic

sensor or the Touch sensor. Both can work. Your robot must not push the victim! A touch is OK but the victim cannot move.
