Answers.Text: Thanks for your looking into it, dear @Alex. Actually I've seen that video before, and if you'll notice - the most important part is missing there. Not during the video, nor in 7:48 picture - the actual pare that is connected to the SG90 moving part - is missing. You can see (in the porccess) that there is a combination of some screws and a Technic brick, but I can't identify the parts, nor the way to connect them. Thanks again!

  <p>So, what I need now, and a way to connect the SG90 motor to a similar kind of construction, to achieve a similar outcome as in the video (and in the question).</p>

  There are numerous solutions over internet for attaching SG90 servo with LEGO. However I remember this [particular video](https://www.youtube.com/watch?v=3m0FgZjfbdM), which fit your need to attach/control Technic beams/liftarms. It also features required parts for this build at [7:48](https://youtu.be/3m0FgZjfbdM?t=468).
