| # Placement Assets 资产库 |
|
|
| 这是一个面向机器人仿真与 placement 任务的统一资产库,当前托管在 Hugging Face Dataset: |
|
|
| ```text |
| https://huggingface.co/datasets/yuchi233/Placement_Assets |
| ``` |
|
|
| 本仓库不是 RoboCasa 的镜像,也不是基于 RoboCasa 单独建立的资产库。RoboCasa、DISCOVERSE、TinyForge、Hunter 和第三方资产站都被视为不同的资产来源,统一纳入同一套存储、命名、索引和溯源规范。 |
|
|
| ## 当前已入库资产 |
|
|
| - RoboCasa 洗碗机 fixture: |
| - 路径:`assets/robocasa/raw/fixtures/dishwashers/` |
| - 数量:25 个 MJCF 资产 |
| - 每个资产保留 `model.xml`、`visuals/` 和本地 `metadata.yaml` |
| - RoboCasa 洗碗机相关辅助文件: |
| - registry:`assets/robocasa/raw/fixtures/fixture_registry/dishwasher.yaml` |
| - fixture 实现参考:`docs/source_notes/robocasa/dishwasher_fixture.py` |
| - DISCOVERSE models 集合: |
| - 路径:`assets/discoverse/raw/collections/models/discoverse_models/` |
| - 内容:MJCF、URDF、mesh、PNG/reference image 等 |
| - 处理方式:作为 collection-level asset 入库,内部保持 DISCOVERSE upstream 的 `models/` 目录结构,避免破坏 MJCF include 和 mesh 相对路径 |
|
|
| ## 统一目录结构 |
|
|
| 原始资产使用 `raw/`,保留来源结构和相对引用: |
|
|
| ```text |
| assets/<source>/raw/<asset_type>/<category>/<asset_id>/ |
| ``` |
|
|
| 示例: |
|
|
| ```text |
| assets/robocasa/raw/fixtures/dishwashers/Dishwasher031/ |
| ``` |
|
|
| 派生资产使用 `derived/`,用于保存凸分解、collision mesh、清洗结果、格式转换等生成物: |
|
|
| ```text |
| assets/<source>/derived/<asset_type>/<category>/<asset_id>/ |
| ``` |
|
|
| 如果要创建凸分解脚手架,可以先运行: |
|
|
| ```bash |
| python scripts/scaffold_convex_decomposition.py assets/robocasa/raw/fixtures/dishwashers/Dishwasher031 |
| ``` |
|
|
| 大规模 upstream 资产树如果包含大量内部相对引用,也使用 `raw/` 结构,但可作为集合资产保存: |
|
|
| ```text |
| assets/<source>/raw/<asset_type>/<category>/<asset_id>/ |
| ``` |
|
|
| 示例: |
|
|
| ```text |
| assets/discoverse/raw/collections/models/discoverse_models/ |
| ├── metadata.yaml |
| ├── mjcf/ |
| ├── meshes/ |
| └── urdf/ |
| ``` |
|
|
| ## 命名规则 |
|
|
| 目录字段: |
|
|
| ```text |
| assets/<source>/raw/<asset_type>/<category>/<asset_id>/ |
| ``` |
|
|
| - `source`:资产来源,使用小写 snake_case,例如 `robocasa`、`discoverse`、`tinyforge`、`hunter`、`third_party` |
| - `asset_type`:资产类型,例如 `fixtures`、`objects`、`scenes`、`robots`、`collections` |
| - `category`:类别,例如 `dishwashers`、`models`、`cups`、`cabinets` |
| - `asset_id`:优先保留 upstream 稳定 ID,例如 `Dishwasher031` |
|
|
| 全局 asset_id: |
| |
| ```text |
| <source>.<asset_type>.<category>.<upstream_id> |
| ``` |
| |
| 示例: |
| |
| ```text |
| robocasa.fixtures.dishwashers.Dishwasher031 |
| discoverse.collections.models.discoverse_models |
| ``` |
| |

| |
| ## 索引与 metadata |
|
|
| 全局索引文件: |
|
|
| ```text |
| manifest/assets.jsonl |
| ``` |
|
|
| 每个资产目录也必须包含: |
|
|
| ```text |
| metadata.yaml |
| ``` |
|
|
| 必需字段包括: |
|
|
| - `asset_id` |
| - `source` |
| - `source_asset_id` |
| - `asset_type` |
| - `category` |
| - `format` |
| - `entry_file` |
| - `license` |
| - `origin_url` |
| - `path` |
| - `tags` |
|
|
| 推荐字段包括: |
|
|
| - `readiness_level` |
| - `source_commit` |
| - `retrieval_date` |
| - `conversion_tool` |
| - `conversion_notes` |
| - `raw_sha256` |
| - `validation_status` |
|
|
| ## 原始结构与当前结构映射 |
|
|
| 如果导入时修改了 upstream 的目录结构,必须记录原始结构和当前结构的对应关系。 |
|
|
| 统一记录位置: |
|
|
| ```text |
| docs/structure_mapping.md |
| docs/source_notes/<source>.md |
| ``` |
|
|
| 当前例子: |
|
|
| ```text |
| DISCOVERSE upstream: |
| /home/yuchi/projects/DISCOVERSE/models/ |
| |
| 当前仓库: |
| assets/discoverse/raw/collections/models/discoverse_models/ |
| ``` |
|
|
| RoboCasa 洗碗机则是一对一映射: |
|
|
| ```text |
| robocasa/models/assets/fixtures/dishwashers/Dishwasher031/ |
| → assets/robocasa/raw/fixtures/dishwashers/Dishwasher031/ |
| ``` |
|
|
| ## 资产就绪度 L0–L5 |
|
|
| 资产存进仓库不代表可以直接用于产数。就绪度单独记录: |
|
|
| - L0:已通过目标任务、机器人 embodiment、policy、verifier 和 episode replay 验收,可稳定产数 |
| - L1:在原仿真器中是完整可运行资产,但尚未适配目标产数链路 |
| - L2:已有 articulated 结构,但物理、碰撞、任务语义等信息不完整 |
| - L3:可动部件已分离,但缺少可靠 joint |
| - L4:完整静态整件 |
| - L5:原始、缺件、未装配或需要显著修复的静态 mesh |
|
|
| 完整标准见: |
|
|
| ```text |
| docs/asset_readiness_classification.md |
| ``` |
|
|
| 当前状态: |
|
|
| - RoboCasa dishwasher:`L1_candidate` |
| - DISCOVERSE collection:`L1_L2_candidate_by_subasset` |
|
|
| ## 凸分解结果存放方式 |
|
|
| 凸分解结果属于派生资产,不能覆盖原始 mesh,也不能直接混进 upstream 的 `raw/` 目录。 |
|
|
| 统一存放路径: |
|
|
| ```text |
| assets/<source>/derived/convex_decompositions/<category>/<asset_id>/ |
| ``` |
|
|
| 示例: |
|
|
| ```text |
| assets/robocasa/derived/convex_decompositions/dishwashers/Dishwasher031_vhacd_v1/ |
| ├── metadata.yaml |
| ├── source_refs.yaml |
| ├── meshes/ |
| │ ├── door/ |
| │ │ ├── part_000.obj |
| │ │ └── part_001.obj |
| │ └── rack0/ |
| ├── mjcf/ |
| │ ├── convex_assets_include.xml |
| │ ├── convex_geoms_include.xml |
| │ └── convex_collision_include.xml |
| └── logs/ |
| └── decomposition.json |
| ``` |
|
|
| 其中: |
|
|
| - `metadata.yaml`:记录派生资产 ID、license、来源、算法、参数文件、验证状态 |
| - `source_refs.yaml`:记录对应的原始 asset、原始 XML、原始 mesh 路径 |
| - `meshes/`:保存凸分解后的 convex pieces |
| - `mjcf/convex_assets_include.xml`:在 MJCF 顶层 include,用来注册 convex part mesh |
| - `mjcf/convex_geoms_include.xml`:在目标 body 内 include,用来添加 collision geoms |
| - `mjcf/convex_collision_include.xml`:带 wrapper body 的独立预览/便利 include |
| - `logs/decomposition.json`:记录 VHACD / CoACD 等工具版本、参数、输入输出 hash |
| - `logs/parts_summary.csv`:记录每个 part 的 bbox 尺寸、中心、体积、面积、顶点数和面数,方便筛查过小/过大的 collision part |
|
|
| 实际运行 CoACD 凸分解: |
|
|
| ```bash |
| pip install trimesh coacd |
| |
| python scripts/run_convex_decomposition.py \ |
| assets/robocasa/raw/fixtures/dishwashers/Dishwasher031 \ |
| --mesh visuals/door.obj \ |
| --mesh visuals/rack0.obj \ |
| --variant coacd_v1 \ |
| --register-manifest |
| ``` |
|
|
| MuJoCo 接入方式: |
|
|
| ```xml |
| <!-- MJCF 顶层 --> |
| <include file="path/to/mjcf/convex_assets_include.xml"/> |
| |
| <!-- 目标 body 内部 --> |
| <include file="path/to/mjcf/convex_geoms_include.xml"/> |
| ``` |
|
|
| 不要直接修改 `raw/` 里的 `model.xml`。如果要替换原始 collision,应该在下游任务工程里选择性 include 派生 collision 文件。 |
|
|
| 凸分解后的 part 尺寸不能直接通过“目标长度/目标体积”指定,CoACD 主要通过粒度参数间接控制: |
|
|
| ```text |
| --threshold 越小通常越细,part 更多/更小;越大越粗,part 更少/更大 |
| --max-convex-hull 限制最多生成多少个 convex hull;越小越粗 |
| --no-merge 禁止合并 hull,通常会保留更多/更小的 part |
| --mcts-max-depth 允许更深层递归切分,可能得到更细的结果 |
| --resolution 提高几何采样/细节分辨率 |
| ``` |
|
|
| 粗 collision 示例: |
|
|
| ```bash |
| python scripts/run_convex_decomposition.py <raw_asset_dir> \ |
| --mesh <mesh.obj> \ |
| --threshold 0.08 \ |
| --max-convex-hull 8 |
| ``` |
|
|
| 细 collision 示例: |
|
|
| ```bash |
| python scripts/run_convex_decomposition.py <raw_asset_dir> \ |
| --mesh <mesh.obj> \ |
| --threshold 0.02 \ |
| --max-convex-hull 32 \ |
| --no-merge \ |
| --mcts-max-depth 4 |
| ``` |
|
|
| 完整规范见: |
|
|
| ```text |
| docs/convex_decomposition_spec.md |
| ``` |
|
|
| 该文档包含 `scripts/run_convex_decomposition.py` 的完整使用方法、所有 CLI 参数说明、粗/细分解参数 preset,以及 rack / wire-like 资产的注意事项。 |
|
|
| ## Primitive collision proxy 结果存放方式 |
|
|
| 对于洗碗机 rack、钢丝架、栅格、插槽隔板这类 thin rod / wire-like 资产,如果 CoACD / VHACD 会把功能空隙填死,优先使用 primitive collision proxy。 |
|
|
| 统一存放路径: |
|
|
| ```text |
| assets/<source>/derived/primitive_collision_proxies/<category>/<asset_id>/ |
| ``` |
|
|
| 示例: |
|
|
| ```text |
| assets/robocasa/derived/primitive_collision_proxies/dishwashers/Dishwasher031_rack1_primitive_boxes_v1/ |
| ├── metadata.yaml |
| ├── source_refs.yaml |
| ├── README.md |
| ├── REPORT.md |
| ├── proxy/ |
| │ └── primitive_collision_proxy.json |
| ├── mjcf/ |
| │ ├── primitive_geoms_include.xml |
| │ └── primitive_collision_include.xml |
| ├── curobo/ |
| │ └── primitive_world.yml |
| └── logs/ |
| ├── cuboids_summary.csv |
| └── proxy_generation.json |
| ``` |
|
|
| 实际运行示例: |
|
|
| ```bash |
| python scripts/run_primitive_collision_proxy.py \ |
| assets/robocasa/raw/fixtures/dishwashers/Dishwasher031 \ |
| --mesh visuals/rack1.obj \ |
| --variant rack1_primitive_boxes_v1 \ |
| --segment-length 0.03 \ |
| --padding 0.001 \ |
| --min-half-extent 0.0015 |
| ``` |
|
|
| 其中 `proxy/primitive_collision_proxy.json` 是 source of truth,MuJoCo 和 cuRobo 输出都从同一份 JSON 派生。 |
|
|
| 完整规范和参数说明见: |
|
|
| ```text |
| docs/primitive_collision_proxy_spec.md |
| ``` |
|
|
| ## 第三方资产规则 |
|
|
| 第三方来源可以先只记录链接,不下载、不入 manifest。 |
|
|
| 只有当某个项目、实验、任务或生成场景实际使用了第三方资产时,才把具体使用到的资产复制进本仓库: |
|
|
| ```text |
| assets/third_party/raw/<asset_type>/<category>/<asset_id>/ |
| ``` |
|
|
| 导入时必须记录: |
|
|
| - 原始 URL |
| - provider / site name |
| - license |
| - retrieval date |
| - source asset ID |
| - 本地路径 |
| - 转换或清洗步骤 |
| - 必要时记录 hash |
|
|
| 候选第三方来源见: |
|
|
| ```text |
| docs/external_source_catalog.md |
| docs/source_notes/third_party.md |
| ``` |
|
|
| 重要规则: |
|
|
| - link-only candidate 不写入 `manifest/assets.jsonl` |
| - 下载数量不等于可生产资产数量 |
| - 来源库总量不能直接相加,必须处理上游派生和重复资产 |
|
|
| ## 校验 |
|
|
| 在仓库根目录运行: |
|
|
| ```bash |
| python scripts/validate_asset.py --all |
| ``` |
|
|
| 当前期望输出: |
|
|
| ```text |
| validated_assets=26 |
| ``` |
|
|
| 也可以校验单个资产: |
|
|
| ```bash |
| python scripts/validate_asset.py assets/robocasa/raw/fixtures/dishwashers/Dishwasher031 |
| ``` |
|
|
| 校验内容包括: |
|
|
| - `metadata.yaml` 是否存在 |
| - `entry_file` 是否存在 |
| - 资产目录是否符合四层结构 |
| - metadata 与目录字段是否一致 |
| - metadata 与 manifest 是否一致 |
| - MJCF 中的 mesh/texture 文件引用是否能解析 |
|
|

|
|
| ## 后续扩展流程 |
|
|
| 新增资产时按以下步骤: |
|
|
| 1. 确认来源、license、可再分发性和用途。 |
| 2. 确定资产粒度:单资产还是 collection-level asset。 |
| 3. 放入统一四层目录结构。 |
| 4. 保留 upstream 文件名和相对路径,除非有兼容性原因。 |
| 5. 添加 `metadata.yaml`。 |
| 6. 更新 `manifest/assets.jsonl`。 |
| 7. 如果改了目录结构,更新 `docs/structure_mapping.md` 和 `docs/source_notes/<source>.md`。 |
| 8. 运行 `python scripts/validate_asset.py --all`。 |
| 9. 上传到 Hugging Face。 |
