assets: bi-dexhands source objects (bottle_cap/cup/pen, Apache-2.0) + local_bottle_cap MJCF/URDF
Two additions for the WUJI dexterous-5 batch (WUJI_SimBench PR #89):
assets/local_bottle_cap/ — the project-authored bottle+cap articulation (MJCF + URDF twin) that hand_track.open_bottle_cap references; it was missing from the bundle, so the task only built on machines with the local file.
assets/bi-dexhands/{bottle_cap,cup,pen} — the raw Bi-DexHands (PKU-MARL/DexterousHands, Apache-2.0, commit dc41afd) task-object assets with upstream LICENSE + ATTRIBUTION.md, imported for provenance and future mesh-based task upgrades (not yet wired into any task; conversion + re-validation is a tracked follow-up).
Great work, thanks for your PR
Superseded by #22, which carries the identical bi-dexhands content plus a v2 redesign of assets/local_bottle_cap (real screw cap — slide+twist coupled at 18 mm/turn so it can only be twisted open; lathe-generated quality meshes with a matching visual thread helix). Opened as a new PR because this contributor token cannot push additional commits to an existing PR ref. Closing this one in favour of #22.
Correction to my previous comment: this PR is already MERGED (thanks!), so nothing to close. #22 is the follow-up — it only changes assets/local_bottle_cap (v2 screw-cap redesign); the bi-dexhands content it carries is byte-identical to what this PR merged.
