Intro
Hi!
I am a undergrad student at IITM, I use MuJoCo for simulating a soft flexible rod kind of structure.
My setup
I use Mujoco version 3.3.2 in python in windows 10
My question
I am trying to model an existing model that we have made using disc and foam which is similar to an flexible rod kind of structure which is tendon driven and has 5 discs through which the tendon passes through but it mainly applies for on the last disc, but idk why the model is oscillating up and down, even if i don't give any inputs, it also gives warning as WARNING: Nan, Inf or huge value in QACC at DOF 0. The simulation is unstable. Time = 0.0060., is there any thing wrong in the tendon actuation or the model itself? Also i am not sure if there are any penetrations in the model.
Minimal model and/or code that explain my question
If you encountered the issue in a complex model, please simplify it as much as possible (while still reproducing the issue).
