Hello,
Not sure what am I doing wrong here, followed a basic tutorial 101 constraint and looked simple but my application was bit more than what I've watched.
so in this picture I added a rotating ring to the grounded base using constraint and it turns 360Degrees, and want to open and close the 6 fingers by rotating the ring with the help of other parts. every thing is moving until the last connection.
the assembly is attached too.
Physically, is impossible to do what you need with the constraints you create.
An example in the image:
In constraint MATE14, you set the faces (white faces in the image) to be connected (parallel), but if the part need to rotate, must exist a certain variable angle between them, as you can see in the image in red.
If you suppress MATE14 it will rotate, but you will need to create other constraints to keep the parts together.
Maybe... showing us the tutorial will help us to find what's wrong with all constraints you are using...
Tip:
For these kinds of movements, check the tool JOINTS
But, be advised that due to movement complexity, they are constraints a lot more faulty and complex to work with...
