Select an object that will represent The Moon and place it in an open location. The students will attempt to circumvent it with their robots.
Mark (using tape) the starting position of the robots (the base) so that they can go to the side of The Moon with a single straight line move.
Don't allow the students to work on the task "Take up to 5 minutes to check if it's possible to program the robot to move forward for 2 seconds by rotating both motors at the same time using only the "run_time" command. Did you succeed?" for more than 5 minutes. In this task, the students have to reach the conclusion that this is impossible because the program is waiting for one motor to stop before the other motor begins moving.
Solution to the task "Now that you know about the fourth input parameter of the run_time command, try again to program the robot to move forward for 2 seconds using only this command.".
Motor(Port.B).run_time(360, 2000, Stop.COAST, False) Motor(Port.C).run_time(360, 2000, Stop.COAST)
The second run_time command must be awaited without a forth False parameter by the program because then the program ends and that stops the motor movement.
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons

Python with LEGO Mindstorms EV3 - Level 1
The course introduces students to the programming language Python. We use LEGO Mindstorms EV3 Robots. Python is a popular programming language. It could be used for introducing students to programming, for academic studies, for developing machine learning algorithms and as a general-purpose language.
During the course, students learn how to read and how to develop Python programs. They use an Integrated Development Environment called Visual Studio Code. Robots are programmed to perform interesting and funny tasks like "bringing you water". The level ends with competition on a playing field with boxes.

Lesson 3 - Luna 3
Introduction
Today we are going to look at a favorite historic moment of ours, namely the Moon landing by the Luna 3 spaceship. Our robot is also called Luna 3 and we will choose an object to represent The Moon.
The robot will go around the "Moon", take a picture and return to base. We will take the picture with a phone set to "continuous shot" or a timer.
If you work fast, you will have a picture at the end of the lesson that you can use to remember it.
