Requirements and considerations when attaching EV3 Ultrasonic sensor to the robot:
- It should be stable – the sensor should not be loose or change its position compared to the ground.
- There should be no obstacles in front of the sensor, such as cables, parts etc, that might prevent the sensor from "seeing".
- It should be horizontal. Otherwise it will always "see" the ground.
- You should always bear in mind the position of the sensor in order to have the correct results. So if you put the sensor at the back of the robot and make it stop when it sees a wall less then 10 cm away, will the program work?
Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons
Level A2. "Space exploration". Robotics with LEGO
The second level of the Robotics with LEGO curriculum for students in second, third or fourth grades.
A new sensor is introduced - the Ultrasonic distance sensor can help the robot avoid obstacles. Students work with new 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. The first robot with chain-treads is built.

Lesson 5 - Navigation in a Labyrinth
Returning feedback to students is important. We try to return feedback constantly in the classes. You should also try to return feedback in a structured way - in a form of a digit. Today you will have to grade your students following this article.

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.
