Install emscripten[edit]
First, you need to install emscripten, which is a compiler toolchain for WebAssembly.
Get the emsdk repo[edit]
git clone https://github.com/emscripten-core/emsdk.git
Enter that directory[edit]
cd emsdk
Download and install the latest SDK tools[edit]
./emsdk install latest
Make the "latest" SDK "active"[edit]
./emsdk activate latest
Activate PATH and other environment variables[edit]
source ./emsdk_env.sh
These variables are set for the current terminal. If you want to make it for all terminals, you can add them to any terminal profile. Here they are:
The environment variables:
EMSDK = < path to emsdk dir >
EM_CONFIG = ~/.emscripten
EMSDK_NODE = < path to emsdk dir >/node/12.9.1_64bit/bin/node
Now just try it![edit]

Build the mujoco_wasm Binary[edit]
First git clone
https://github.com/zalo/mujoco_wasm
Next, you'll build the MuJoCo WebAssembly binary.
mkdir build
cd build
emcmake cmake ..
make

.png)
Tip: If you get an error with "undefined symbol: saveSetjmp/testSetjmp" at the build step, revert to:
./emsdk install 3.1.56 && ./emsdk activate 3.1.56 && source ./emsdk_env.sh
Running in Browser[edit]
Run this in your mujoco folder to start a server.
python -m http.server 8000
Then navigate to:
http://localhost:8000/index.html
Running in Cloud/Cluster and Viewing on Local Machine[edit]
Add extra parameter to your ssh command:
ssh -L 8000:127.0.0.1:8000 my_name@my_cluster_ip
Then you can open it on the browser on your local machine!
Adding New Models[edit]
All the models are stored in the folder examples/scenes, as seen below:
You can add your own model XML and meshes here. For example, here we add the stompy folder.
After adding the model files, run
python generate_index.py
to update file indexes.
Then copy all the content in index.json to mujocoUtils.js, as shown below:
In the end, again at file mujocoUtils.js, add the name and scene file
Then reload again and you can see new models have been added:
