Hello Magut,

Welcome to the Forum. It will be better if you provide more information so we can help you out:

1.  We have over 700 Robots included in our courses. Which one did you try?

2. You did not notice a difference compared to what?

3. What exactly did you not understand.

The clearer the question is, the more useful answer I will be able to give you.
