Hi,
How can I convert my custom Musculoskeletal Model to MuJoCo model? I would like to use the converted model in the myosuite environment?

Hi,
Firstly, thanks very much for your great work.
When I try to drag the myoarm.xml, myoleg.xml or myohand.xml to the mujoco.viewer to load the model for visualiztaion on the ubuntu system installed in the virtual machine, the system just stucks and it become really slow for me to click or do any other operations. However, if I load the myoelbow model to the mujoco.viewer the same way, it is ok. So, it maybe a problem related to the computer itself, namely, my computer configuration is not enough to render them in the virtual machine that I need to use a computer with better gpu or cpu because of the high model complexity in the arm or leg model, right?

And could you recommend the lowest computer configuration for the model loading or simulation, my computer's cpu is amd ryzen 7 4800H with radeon graphics and gpu is nvidia geforce gtx 1650. If I install doulbe system instead of using virtual machine, would it be better for simulation? Would apple m1 is ok for the simulation?

Thanks so much for your time.

Wishing you all the best.

Hi,

Firstly, kudos for your amazing work! I'm curious how can I transfer marker/keypoints-based real-world motion capture data to MyoSuite for simulating musculoskeletal models, similar to the process in OpenSim?

Additionally, how can I command the joints of these models to follow specific trajectories. Do you have any reference codes or guidance on achieving this?

In the myosuite demo a variant of the myoleg model, called "myoleg (suspended)" can be selected and interacted with.
It would be great to have this suspended version as well as the classic myoleg as a mujoco xml file here.
I realize that obtaining it should be possible with few changes to the original xml, though the original suspended myoleg implementation could be safer and would be more guaranteed to function as desired.

Hi,
Will you be releasing the XML files corresponding to the MJB binaries? Would really help if we want to tinker with the models, by adding on an exoskeleton or simulating sarcopenia.

If not, any suggestions on how to do these mods with just the binaries?

Hello,
I have a question regarding the following code snippet:
import myosuite
import gym
env = gym.make('myoElbowPose1D6MRandom-v0')
env.reset()
for _ in range(1000):
env.sim.render(mode='window')
env.step(env.action_space.sample()) # take a random action
env.close()
In this code, I noticed the usage of the gym.make function with the argument 'myoElbowPose1D6MRandom-v0'. I'm curious about how this function call is handled and if there is a specific file that controls the environment with the name 'myoElbowPose1D6MRandom-v0'.

Could you please provide some insight into the internal workings of gym.make and how it retrieves and initializes the specified environment? Additionally, I would appreciate any information on the file structure or configuration associated with the environment named 'myoElbowPose1D6MRandom-v0'.

Thank you in advance for your assistance!

Best regards,

Hi,

Would it be possible to release the arm model as a xml file?

Thanks in advance!

I have tried to run any .mjb file with it, but I keep getting the error 'ValueError: mj_loadModel: failed to load from mjb.' I've tried to investigate, but it seems like this is not a Mujoco-related issue. I am using Mujoco version 2.3.7 on Windows 11.
