Re: the problem that the joint exceed the position scale
Thanks for your reply! And I already tried the newton egine and it performs better. But it seems that not all the problem is solved. As you mentioned, i need to adjust the mass, while the question is that how should we process the universial joint because the link in this kind of joint is light. Is ...

It is true that the model will get the force from the ground because of the gravity, but why does that still happen even though ...
