The goal is to have a model as same as pic 4 which is the one side of our robot. For now, the simplified model can be seen in picture 1,2,3. I built my model and connect 3 simple parts of the model together . I get different error that I would like to share with you in the meeting. Here is the summary of my questions:
  1. As you can see in picture 3 , three cable module which has the spools and pulley inside or attached to it, are connected to 3 ankers. And these cable modules are connected to Rocap which is a solid body for now as you can see in the model. I tried different method for connection with weld and solid body connection, but I am not sure which on is the best because they messed up the visual of my model!
  2. My other question is when I connected these three cable modules to the Rocap to have the complete model, I wanted to relocate the Anker position in the space to have better angle respect to my pullet 2 of them were located without any problem but when I tried for cable_module_2 it completely messed up my model.
These are main issues.

Hi there. I looked at your model and simplified based on my best guess from the diagrams you attached. I think your original model was missing a connection between the Rocap and ground, and there were some extra joints in the model.
I have simplified it to two connections and put in some actuation to have it move up and down. The adjusted model is attached here and the animation is below. For a similar example, see the example model Cable Robot.

Hi Steve. I hope you are doing great. i checked the model. Here are my questions: I see that to make rocap moving in space you used the Rectangular Joint. Is it any whay that we can let the Rocap be freely moving in the space without conection it to Zero position in space ? I tried to design another model with more anker and Pulley cable and no Joint for Rocap to be conected to world system. There is kienamtic error when i run my model.
