Lesson Summary:

Students program their robot to detect a black line and avoid crossing it.

What You'll Do:

Program your Edison robot by arranging the blocks how they are shown. Be sure to add a loop at the end and choose Edison's speed. create a border with black tape around a table and place your robot inside the border and run the program. Have students experiment different time with the 'reverse' and 'turn back' block as well as using different speeds. Have students report their findings on the paper provided. Then have students think of how this program would work in the real world.
