Unfinished screw-propelled vehicle model. It became the culmination of all my and my daughter's experiments with tracked vehicles. I don't know how it will be for you, but for me, the tracks (hidden) never came off at all, and it climbed almost vertical walls against all odds. The model is unfinished (made from scratch).

I achieved the movement of the screws equal to the movement of the body and reached the desired result. You can finish the rest yourselves. Published as material. Authorship must be indicated.
