I'm struggling to get good performance on Ant (positional). It seems like many episodes terminate early due to failing the is_healthy check.
Test case: I reset 256000 Ant environments and step a fe…

Hey all,
for a project of mine I am using the mujoco mjx pipline and try to train neural networks using JAX. We had the idea to alter the input to the physics step by having a neural network in fro…

Hello Brax team,
I'm interested in simulating an inelastic rope within Brax, similar to [this example](https://mujoco.readthedocs.io/en/stable/_static/example.mp4). When the rope transitions from a…

Hi,
I'm a student who is new to Mujoco (and all simulators really), and I'm trying to use MuJoCo for physical simulation for my project.
I'm just getting start with this. At current stage, I'm t…

Hi,
I'm trying to use MuJoCo (MJX) to simulate a humanoid bipedal robot with several closed linkages. I am using MJX inside BRAX and when I visualize some seconds of trajectory I clearly see that t…

This problem is also discussed in the issue #1142. I have been facing same error i.e. ```NotImplementedError: {2} not implemented.``` but due to presence of an equality constraint in my xml file. I do…

Hi,
I'm trying to get more familiar with MJX to use it for quadruped RL training and so I've been going through the published tutorial.ipynb. I've noticed that the results plotting depends on the n…

Hi,
Thank you for this software, it's really useful for my research. I'm currently running some baseline algorithms with stable-baselines3 and somehow I have trouble instantiating the replay buffe…

Hello,
Thank you for your amazing work with brax, I am excited to use this physics engine for simulations.
I have been running into a particular issue that I don't understand. Below is a simple …

Hi,
first of all thanks for your work on brax!
I have noticed an anomaly when trying to get gradients of different pipelines.
When differentiating the pipeline functions, only the positional …
