Lesson
Learn how to explore your surroundings with your eXperiBot while avoiding obstacles.

Introduction
Many assistance systems and sensors in modern cars help ensure safe driving today. They detect obstacles such as other cars, bicycles, or people. If something is in the way, the car can, for example, warn the driver or brake automatically. This makes driving safer and provides support for the driver.
Today, your eXperiBot should work in a similar way: it should avoid obstacles and do so automatically.
Learning goals
In this lesson, you will learn…
how to explore the environment with your eXperiBot,
how to detect obstacles with the eXperiBot’s Multisensor,
how to avoid obstacles with your eXperiBot.
Units
Get your eXperiBot ready to go.
Create a program that allows your eXperiBot to explore its surroundings. When your eXperiBot detects an obstacle, it should reverse.
Set the sensitivity of the Multisensor and try out different values. Observe the distance from which your eXperiBot can avoid obstacles.
Extend your program: When your eXperiBot detects an obstacle, it first plays a short sound and then moves away.
Bonus units
Two eXperiBots should move toward each other and swerve out of the way as soon as they recognize each other. Test whether your program works for this or whether you need to change it.
