You already have your square with the robot.
Now, let's compare different castor wheel constructions. Build them all or borrow them from other students in the classroom. Take turns so that everyone can use every caster wheel construction and note the results in the challenge below.
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 2 - Third Wheels and Square
Intro
Today we will test different support wheels and determine which one is most suitable for a robot that we will send to the moon.
The robot on the moon will be powered by a solar battery, but that means it has very little electricity and must not waste much of it to turn and navigate. You will need to find which support wheel resists the least when turning.
Another terrible problem would be if the robot got stuck. It will be too expensive to send a mechanic to the moon to help him. We will have to determine which wheels would get stuck easily in a small hole and which wheel can the robot pull out.
All teams should build different third wheels after which students can swap them.
At the end of the lesson, the most successful teams will be awarded a bonus task!

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 5 - Ultrasonic sensor
Remember to provide feedback to students regularly. It's important to give structured feedback in the form of a grade. Today, you'll need to grade your students following this article.
