# home-robot: build map

Official home-robot python main example for build map. Inspect the pinned source and upstream setup before use.

ID: `home-robot-projects-offline-mapping-build-map-py`

Record version: `source-f30d65529768b4b6a6ba3988604a44dad0276d85232d7a1815e8c697fc27ec39`

Hub commit: `f97266a5cdd2c600cd376397a54892f08290df20`

## Access

Fetch the pinned repository, verify this source checksum, and use upstream installation and invocation. This record does not install or execute code.

Optional inert file retrieval: `python /PATH_TO_SKILL/scripts/rsh.py fetch-source home-robot-projects-offline-mapping-build-map-py --expected-source-revision ede6a67a2d0c0c8e12ad3b9726f330cea6cf90f5 --expected-source-sha256 f30d65529768b4b6a6ba3988604a44dad0276d85232d7a1815e8c697fc27ec39 --project ./experiment --json`. This verifies one file, preserves provenance and never installs or runs it. See [source-file retrieval](https://hub.superfastrobotics.com/source-files.md).

Hub preparation adapter: **false**. Runtime verification: **not_run**.

## Requirements

```json
{
  "python": "Inspect the pinned upstream package metadata for the supported Python version.",
  "packages": [],
  "display": "Upstream simulator, robot model, build, display and device requirements; inspect the selected source.",

  "source_imports": [
    "PIL",
    "click",
    "cv2",
    "glob",
    "home_robot.core.interfaces",
    "home_robot.mapping.semantic.categorical_2d_semantic_map_module",

}
```

## Invocation

```json
{
  "entrypoint": "python projects/offline_mapping/build_map.py",
  "notes": "Source reference only. Install the pinned upstream project and its stated dependencies explicitly. Robot bridges may actuate hardware; no hardware execution is established. Asset, model, SDK and data terms remain separate."
}
```

## Compatibility

```json
[]
```

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

## Evidence

Level: **source_reviewed**. Runtime verification: **not_run**.

Fetched and SHA-256 checked this immutable source; statically parsed Python or located native main; verified pinned license bytes and checked explicit per-file license identifiers. No upstream code executed.

Source review and contributor reports do not establish task completion. Preserve upstream attribution and licenses.
