In this lesson, students will navigate the same labyrinth as in Lesson 3, but this time using the distance sensor. The most important concept for them to remember is the construction: go forward until something happens and then stop. This was used in Lesson 3, so it's a kind of revision with a new sensor. The idea remains the same: the robot goes forward until it gets close to the wall and then turns.
In this lesson, we don't encounter the same problem as in Lesson 3, where the robot had difficulty turning properly due to needing to touch the wall. With the distance sensor, the robot can use any turn without touching the wall. Feel free to point that out to the students.

Level A2 - History and Mythology - Robotics with LEGO SPIKE Prime
This is the second level of the LEGO Robotics Curriculum for second, third, and fourth-grade students.
In this level, we will focus on History and Mythology, with each lesson covering a different aspect of the ancient world. You will learn about a new distance sensor that uses ultrasound to help a watchtower robot detect invaders. We will also introduce new concepts such as loops, degrees, and a third motor. Additionally, you will learn how robots can perform two different tasks simultaneously.

Lesson 6 - Exploring an Egyptian pyramid
Introduction
Have you heard of the Egyptian pyramids? What do you know about them?
Near the city of Cairo, there are three pyramids. The largest of them is the Great Pyramid of Giza. It is around 4600 years old and was built during the Old Kingdom of Egypt. It is so old that historians say we live closer to the Roman Empire than the Roman Empire was to the building of the pyramids! It was used as a tomb for Pharaoh Khufu. To preserve the body of the pharaoh, the pyramid was constructed like a labyrinth to prevent anyone from finding it. To study the pyramid, our robot will need to navigate this labyrinth.
Since the pyramid is so old and full of delicate hieroglyphs, using a force sensor to navigate is not an option, as even light touches might damage the writings. That's why we will use our new sensor: the distance sensor!
