Any physics toolbox experts out there?

Can a conveyor belt be attached to a moving object? The base can but the rollers have a world hinge constraint that allows them to roll but keeps them in place regardless of the attachment. I need a conveyor belt on a moving vehicle for my contest entry.

Any thoughts?

Someone can tell me how they are recorded with the box of physical movements, I must be very donkey then fail to do so


Alguien me puede decir como se graban los movimientos con la caja de fisica, debo de ser muy burro pues no consigo hacerlo

I already started a thread with the suggestion before seeing this, but I will ask if those of you who have experience with the physics toolbox are able to make a vehicle with a trailer. Utility trailer. Boat trailer. 18 wheeler trailer. Keeping in mind that works as it should with regard to physics. Thanks!
