Fix croodinate pickment - #514
Conversation
Greptile SummaryThe PR updates coordinated-pickment assets and gripper parameters, versions the antipodal cache, and expands antipodal ray origins to recover missing contact pairs.
Confidence Score: 4/5The PR should not merge until optional tutorial assets are resolved lazily so unrelated object selections do not fail during import. The module-level preset construction unconditionally enters the download path for two new assets before command-line selection, while the remaining accepted feedback concerns explicit public API declarations.

| Filename | Overview |
|---|---|
| embodichain/data/assets/obj_assets.py | Adds two downloadable dataset classes, but leaves their public exports implicit rather than declaring all. |
| embodichain/toolkits/graspkit/pg_grasp/antipodal_generator.py | Versions antipodal cache filenames so results generated by the revised algorithm do not reuse stale cache entries. |
| embodichain/toolkits/graspkit/pg_grasp/antipodal_sampler.py | Adds a second ray-origin batch intended to recover contact pairs missed by the original raycast range. |
| scripts/tutorials/atomic_action/coordinated_pickment.py | Adds new presets and changes the default scene, but eagerly resolves both downloadable assets during every module import. |
| scripts/tutorials/atomic_action/tutorial_utils.py | Adjusts gripper sampling geometry and allows callers to provide an initial robot joint configuration. |

### Issue 1
scripts/tutorials/atomic_action/coordinated_pickment.py:139
**Assets resolve during module import**
If either new asset is absent from the local cache and the download service is unavailable, constructing `OBJECT_PRESETS` invokes `get_data_path` before argument parsing and aborts the import. This prevents the tutorial from running even when the user selects an existing local object such as `pencil` that does not require either new asset.
### Issue 2
embodichain/data/assets/obj_assets.py:243
**Public asset exports remain implicit**`PlasticTray` and `WaterBasin` are new public dataset classes, but the module does not declare them through `__all__` as required for public modules. Because the assets package imports this module with a wildcard, its exported API remains dependent on implementation-level names rather than an explicit declaration.

Pull request overview
This PR targets the coordinated pickment tutorial and the antipodal grasp pipeline by adjusting tutorial gripper parameters, adding new downloadable object assets, and changing antipodal sampling/caching behavior to address missing contact-pair annotations.
Changes:
- Update tutorial gripper constants and allow overriding UR5+gripper initial joint positions (
init_qpos) in tutorial helpers. - Extend the coordinated pickment tutorial with new object presets (PlasticTray/WaterBasin) and tweak scene/options parameters.
- Adjust antipodal raycasting behavior and invalidate old antipodal caches via a versioned cache key; register new object asset datasets.

- Calling get_data_path() while building OBJECT_PRESETS runs dataset resolution/download at module import time (even when a different --object is selected). Prefer storing the relative asset path here and letting resolve_cached_data_path() handle resolution when the object is created.
