Flexiv Robotics Rizon4
This package contains a MuJoCo robot description (MJCF) of Rizon4 developed by Flexiv Robotics.
The first time takes a moment
Opening this model fetches it from the Menagerie repository — the scene, the robot and the meshes it references, about 6 MB — and keeps it here, so anyone opening it after you gets it straight away. Nothing of yours is uploaded in the process: the simulation itself runs in your tab, on MuJoCo compiled to WebAssembly.
What you can do with it here
- Simulate it under gravity and contact, write a controller in JavaScript, shove it with the mouse, and run the four repeatable tests that answer with a number rather than an impression.
- Look inside it: the kinematic tree, every joint and its range, collision geometry against the visual mesh, where the mass actually sits.
- Convert it to URDF for ROS, or to USD for Isaac Sim — each direction states what it could not carry across.
- Author a movement for it and check the motors it declares can actually perform what you drew.
Whose model this is
The Flexiv Robotics Rizon4 model is Apache 2.0 licensed and was published by Flexiv as part of the MuJoCo Menagerie, curated by Google DeepMind. This page is a way to open it, not a claim on it — the folder upstream carries the licence text, the changelog and the README its authors wrote:
https://github.com/google-deepmind/mujoco_menagerie/tree/main/flexiv_rizon4
If you use the model in your own work, credit that folder rather than this page. If it has changed upstream since we fetched it, the copy here is the one you get — say so in a bug report and it will be re-fetched.
