The challenge

Program the robot to move six times:

a great distance forward and backward;
then some smaller distance forward and backward;
and finally a very small distance forward and backward.

Possible settings

Choose the distances on your own and according to the space you have available.
The easiest numbers could be 3, 2, 1 rotations, but feel free to be creative and choose your own values.

Courses with this episode

The episode is used in the following courses where you can find additional tasks for it to use in class

EV3 Phi. Introduction to robotics with LEGO Mindstorms

Robotics with LEGO - First Level (Deprecated)

Level A1. Introduction. Robotics with LEGO

Robotics with LEGO - Level 1.0 - Adventure in Space

The challenge

Program the robot to move six times:

forward and backward for some long distance;
then forward and backward for some shorter distance;
and finally forward and backward for very short distance.

Possible settings

Choose the distances on your own, and according to the space you have available.
The easiest numbers could be 3, 2, 1 rotations, but be free to feel creative and choose your own values.

English

You already know how to use a number of blocks and the next few tasks are about the Yo-yo challenge. What you should do is to program the robot to move forward for a long distance, backward for a long distance then forward for a short distance shorter backward for a shorter and then forward for even shorter distance and backward for even shorter distance. So, like 6 movements. Try to implement it in a program in the next following tasks.

EV3 Phi. Introduction to robotics with LEGO Mindstorms

The things that you will be able to do with your EV3 robot by the end of this course are:

Freely move your robot towards desired target;
Avoid obstacles on the path of your robot using sensors;
Follow lines of any shape;
Detecting and picking up objects of any kind;

Series of instructions make a program

The challenge is to make the robot move back and forth with ever decreasing distance.

Robotics with LEGO - Level 1.0 - Adventure in Space

The first level of the Robotics with LEGO curriculum for students in fifth to twelfth grades.

Various constructions with robots are built. Learn how to control the motors so that the robot navigates around the Moon and Earth in various ways. Getting to know the first two sensors. The robot can feel its surroundings with the help of the Touch sensor and avoid obstacles.
The Ultrasonic distance sensor can help the robot avoid obstacles. Students work with concepts like loop, degrees and medium motor. Robots can now do two different actions at the same time - while solving missions on a field, the third motor clears detected obstacles.

Lesson 1 - Moving like a Yo-Yo

Introduction

Today, you will get to know your classmates and your teacher, learn how the lessons are conducted, construct your first robot, and learn how to program it to move. The end goal of this lesson is to make the robot move like a Yo-Yo. How does a Yo-Yo move?

If you have ever owned a Yo-Yo, you know that it's meant to fall down and rise back up to your hand. But in order for it to move successfully, we need to move our arm in such a way that we provide it with the required velocity. Otherwise, it will decrease the distance on the way back up on each drop until it stops.

Try to make a good impression on the rest of your class, because you will be doing this course with them until the end.

Level A1. Introduction. Robotics with LEGO

Introduction to robotics - The first level of the Robotics with LEGO curriculum for students in second, third or fourth grades. A journey in space, with robots. Various constructions with robots are built. Learn how to control the motors so that the robot navigates around the Sun, the Moon and Earth in various ways. Getting to know the first of the sensors. The robot can feel its surroundings with the help of the Touch sensor and avoid obstacles.

Lesson 2 - Yo-yo challenge

Introduction

Today we will learn to program the robot to perform more than just one action, as well as program it to move like a yo-yo. Have you ever played with a yo-yo? How does it move? Did you know that from Filipino yo-yo means "to return".
