Please post your model in the neutral configuration. In that case also, if we make the IK for that mechanism, do you agree if we use it as a example V-REP scene on our website and/or software?

Cheers

I am really happy to hear that you want to help me with our model~ I have noticed the importance that sometimes the common method to calculate inverse kinematic would not works as the configuration has some special geometric feature. Here is the link of our STL model and the thesis paper script with the inverse kinematic and Jacobian matrix you may need.
stl file:

and here is some picture to define the angle and coordinate of the model

As for the use as example or put it into your software, I think it's good for other user, for I have notice there are many parallel configuration problems are not solved. But the model is designed by our laboratory originally and my supervisor want to publish some paper with this configuration. I think its a interesting configuration and if you want to use it, please let me known and make the statement with our laboratory.
My email is

,you can contact me in anytime. I will gave you the information of my laboratory and my supervisor, or other information of our model and questions that I don't express clearly.

and nowadays, I have started to write the inverse kinematic solution with Lua, If I have any improvement, I will let you known it in the first time : )

Usually we do not offer to help in that way, But if we have to go through additional hoops and loops to check permission with your lab, then we'll just leave it to it. Sorry.
Btw, you posted your mechanism openly on this forum, that's why I thought it would be ok to use it as an example.

Cheers
