According to my experience, the production method of Lego box is basically to design the scheme first, collect materials, then build the frame, add motors and transmission devices, install sensors and controllers, add decorations and details, and finally test and adjust.

This is just a basic guide, you can adjust and innovate according to your own ideas and needs. Making Lego boxes requires patience and creativity. I hope you can enjoy the production process and create your own unique works!
