This model is not original, I learned it from online videos. You can build this work using LEGO 45544 series and 45560 series parts. I tested that when the large motor rotates 80 degrees, the mechanical diamond moves most smoothly, provided it is on a smooth surface. (Example: tile surface) The ultrasonic sensor does not need to be connected to the data cable. It is just a decoration, but the ultrasonic sensor lights up more like eyes! If you like my video, you can help me like it, share it, and subscribe to my channel. I will be very grateful to you.
