MuJoCo 4.0: What Changed in DeepMind's Physics Engine and How to Try It
The Brief
- MuJoCo 4.0 is reported as released, with changes to DeepMind's physics engine.
- The source is an introductory DEV Community article that covers what changed and how to try it.
- The excerpt provided does not list the specific changes or release date.
Why it matters
MuJoCo is used to simulate contact dynamics for robot policies, so changes to its engine can affect simulation results and how policies behave when moved to the real world.
Who’s affected
- Robotics developers using MuJoCo
- Reinforcement learning teams training policies in MuJoCo simulation

A robot policy can look excellent in a video and still fail when a gripper touches an object, a wheel loses traction or a fast-moving body crosses a thin obstacle between simulation steps. Contact dynamics are where a physics engine earns its keep. MuJoCo is an open-source…
