Introduction
Self-driving robots now work in modern shopping centers. They deliver goods to stores, pick up boxes, or clean the main aisles. To prevent these robots from getting lost, they travel on fixed routes. These routes often feature floor markings or clearly visible paths. The robots follow these markings much as vehicles follow a road.
Today, your eXperiBot should work in exactly the same way: it should learn to recognize a line and become a reliable line follower.
Learning goals
In lesson, you will learn how to…
let your eXperiBot follow a line.
Units
Get your eXperiBot ready to go.
Create a program that makes your eXperiBot act as a line follower.
Create a program that automatically stops your eXperiBot at the end of the line and plays a melody.
Change the loop blocks in your program and analyze the difference between “repeat-while” and “repeat-until.”
Bonus units
Create a program that makes your eXperiBot act as a line follower, following a black line with several curves.
Create a program that makes your eXperiBot stop briefly at the end of the line, turn around, and become a Line follower again. Repeat this sequence continuously.
