MyoSuite is a collection of musculoskeletal environments and tasks simulated with the MuJoCo physics engine and wrapped in the OpenAI gym API to enable the application of Machine Learning to bio-mechanic control problems.

Documentation | Tutorials | Task specifications

Below is an overview of the tasks in the MyoSuite.

Installations

You will need Python 3.8 or later versions.

It is recommended to use Miniconda and to create a separate environment with:

conda create --name myosuite python=3.8
conda activate myosuite

It is possible to install MyoSuite with:

pip install -U myosuite

for advanced installation, see here.

Test your installation using the following command (this will return also a list of all the current environments):

python -m myosuite.tests.test_myo

You can also visualize the environments with random controls using the command below:

python -m myosuite.utils.examine_env --env_name myoElbowPose1D6MRandom-v0

NOTE: On MacOS, we moved to mujoco native launch_passive which requires that the Python script be run under mjpython:

mjpython -m myosuite.utils.examine_env --env_name myoElbowPose1D6MRandom-v0

It is possible to take advantage of the latest MyoSkeleton. Once added (follow the instructions prompted by python -m myosuite_init), run:

python -m myosuite.utils.examine_sim -s myosuite/simhive/myo_model/myoskeleton/myoskeleton.xml

Examples

It is possible to create and interface with MyoSuite environments just like any other OpenAI gym environments. For example, to use the myoElbowPose1D6MRandom-v0 environment, it is possible simply to run:

from myosuite.utils import gym
env = gym.make('myoElbowPose1D6MRandom-v0')
env.reset()
for _ in range(1000):
  env.mj_render()
  env.step(env.action_space.sample()) # take a random action
env.close()

You can find our tutorials on the general features and the ICRA2023 Colab Tutorial ICRA2024 Colab Tutorial on how to load MyoSuite models/tasks, train them, and visualize their outcome. Also, you can find baselines to test some pre-trained policies.
