MuJoCo
Classic physics engine widely used in robot RL and control research — lightweight and accurate.
Curated collection of high-quality MuJoCo robot models (arms, quadrupeds, humanoids) maintained by Google DeepMind.
Why: Best public MJCF robot assets for MuJoCo experiments
MuJoCo Menagerie is DeepMind’s curated set of high-quality robot MJCF assets (arms, quadrupeds, humanoids). It removes the pain of hunting broken URDFs when you just want a trustworthy Franka, Unitree, or humanoid model in MuJoCo.
Use it with MuJoCo or dm_control wrappers. Always check each model’s license and actuator ranges before real-robot transfer.
Learning Path: keep it next to MuJoCo so simulation intro is “engine + good assets,” not engine alone.
Researchers, students, and builders comparing open embodied stacks.
