We will cover the typical reasons why your robot is not moving at all.
When you first start the EV3 brick, you see the recent programs menu. Let's see what it is all about.
How to help students implement long programs.
Let's make a program that moves the robot forward and then backward.
We will demonstrate an alternative way to make the robot move backward
There are number of settings in a Move block and now we will focus on the rotations setting
Sometimes a good teacher needs a few tricks in his sleeve, so that he can surprise and entertain his students.
A note why we give the challenge at the start of the lesson.
The challenge is to make the robot move back and forth with ever decreasing distance.
Here are some guidelines for assigning tasks to students:
Use visible references on the floor. If the floor is tiled, use the tiles. If there are lines, use them as guides. Always clearly mark both the starting point and the finish line.
Students may forget where the start and end points are, so it is important for you, as the teacher, to mark them clearly.
Use one testing area for every 10–12 students and teach them to wait their turn in line. This helps keep the activity organized and fair for everyone.
A task distance of around 50 cm (20 inches) works well. You can also choose a different distance or decide together with the students. Any distance can work, especially if it has meaning.
For example, you can use a meaningful challenge like: “Move the robot as far as your height.”
Decide in advance what counts as a successful result. For example, is 42 cm acceptable? Is 49 cm enough? Is 55 cm too far?
Set clear expectations and help students understand the importance of precision. At the same time, encourage them to try again and improve their results.
Program the robot to move forward by 50cm (20 inches).
Unplug one of the cables and observe what the robot does.
When we, the teachers, make programs and projects, we give them descriptive names. Let's show you a way to put cool names on your programs.
We will cover three ways to transfer your program from the computer to the robot.
It seems obvious and intuitive how to connect the robot and the computer. We must cover that part, so that we are sure you can download our programs to the robot later on.
Now we will create the first program in this course and we will make the robot move forward.
Now we have to program the robot. The steps that we will cover are starting the software, writing a program and downloading it to the robot.
We will demonstrate how to connect the brick and the motors by using cables correctly and reliably.
Overview of what is going to happen that part of the lessons.
We will learn how to connect and disconnect LEGO cables and on which ports exactly to connect the motors.
We will take a look at the EV3 motors and will go into details about them
The most universal way to start your programs is from My Projects menu and we will cover details about that menu in the EV3 Brick.
Do it yourself, fix the errors in the construction of the EasyBot
We will demonstrate the common mistakes students make when building a robot.
Do your best as a teacher to make sure students are expanding their vocabulary on every occasion.
Expanding students' vocabulary is an important part of the learning process.
It is unacceptable when after a few classes your students still say, "I need that blue thing or the red part".
The teacher should encourage students to pronounce the names of the parts on every occasion.
This is easy when students ask you to give them some part from the set or ask you to help them find a piece in the set.
We will cover the names and the basic usage of the parts in our typical robot.
There are some things to be careful about when your students work with the brick.
