Dear all, we have a problem by modelling a 2-Finger Gripper. There is a "Spring Link" to realize a parallel movement of the two fingers. These Spring Link can (somehow) not connected. Attached you can find the XML. Maybe someone has an idea.
I'm a little step closer by using an equaltiy and connect these untidghten parts. This was done according to http://www.mujoco.org/forum/index.php?threads/trouble-with-a-closed-kinematic-loop.3646/. So now they are connected, but i'm still struggeling with the movement. So i can't close the gripper. My suggestion is, that the anchorsetting is wrong?? Or am I wrong (Both attachements should be in one folder)
You need to fix the position of the anchors (red balls), the position of the joints (they are off as well) as well as the joint ranges to obtain the desired behavior.
Many thanks Florian. Nice to see where these coordinates are. Do you can share these visualization? Just to have an example making things transparent and so.
Hi Hauke, Did you figure this out? I have been stuck in the same situation for a while. It will be great if you can share the working model....
