For some students the time period between level "B" and level "C" is long enough to forget some parts of the learned material. In today's class we won't learn new material - we'll practice what we've learned. In this way the teacher can help students recall what they may have forgotten.
In the beginning it's important to let the students program the robot incorrectly. In this way you will attract their attention while you are explaining why they didn't succeed with the task.
Sample solutions to the tasks are presented in the lesson and for the students. It's not forbidden to copy them, if they want to.
The additional tasks include an ultrasonic sensor to the robot. This has a motivational effect to most of the students. You can present it as a reward for the diligent.
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons
Level B1. "Spy gadgets". Robotics with LEGO
The third level of the Robotics with LEGO curriculum for students in second, third or fourth grades.
In these lessons, we stress on more complex and challenging robots. The concept of Condition is introduced. Students learn about physics concepts of inertia and center of mass. Robots with two sensors are built and students program both of them. Programming becomes more complex as robots now can make complex decisions. "Spy"-robots sneakily follow their targets, trying to be undetected.

Lesson 1 - Strange Bot
Intro
Today we're constructing a damaged robot! We will test how it works and if we can use it again or we would have to reconstruct it. Where did this damaged robot come from? Read below.
There are higher risk occupations such as firemen and policemen.
Can you give an example for another dangerous profession?
How many dangerous professions have you heard of?
What are the dangers in these professions?
Would you take a high risk job? Which one?
Would you want to have a robot to help you? What would the robot do?
Many people risk their lives at work, because we haven't yet created and produced robots to do the job for them. But today we're building a robot, which can eliminate the risk of one of the most dangerous professions - the one of the bomb disposal expert.
The job of this expert is to defuse bombs before anyone is injured. It sounds expensive to create a new robot for each bomb a bomb disposal expert has to defuse, but, luckily, it is not necessary. The robots can be repaired or recycled! However, sometimes it's difficult to distinguish where do some of the deformed parts go. Today we're constructing a robot, for which we don't have a right wheel and we have two left wheels. We'll try to program this robot in a way we could reuse it.
