## Requirements

```json
{
  "python": "Not a Python entrypoint; follow the pinned upstream package requirements",
  "packages": [
    "MuJoCo version specified by the pinned model README",
    "Adjacent upstream meshes and included XML definitions"
  ],
  "display": "Model XML often references adjacent meshes or other model XML. Viewer/rendering and MuJoCo/MJX version requirements are model-specific; this index does not fetch those assets or load a model.",
  "execution_domain": "simulation",
  "source_imports": []
}
```

## Invocation

```json
{
  "entrypoint": "Data/configuration artifact: low_cost_robot_arm/low_cost_robot_arm.xml; use its upstream loader or package integration after inspection",
  "notes": "This file is not a standalone program. No Xacro expansion, include resolution, model loading, configuration deployment or robot execution was performed."
}
```

## Compatibility

[]
```

Missing environment fields remain unknown. Source discovery labels do not establish robot compatibility.

## Evidence
