Rigid Links between multiple shapes

[ZZhang]

Hello all, I am an initial user of vrep. I am trying to achieve a cable robotics model in the scenario and I have made a worked model like this. however, after I made another model like this which is based on the last one. the model cannot stable in the first stage. I was thinking is the mass problem of the shapes but it is still not working after the mass changed.
please make a comment if there is anything wrong.

Cheers
