+ # RoboCasa365 Lightwheel Objects — mirror
14
+
15
+ An **unmodified byte-for-byte mirror** of the official RoboCasa "lightwheel objects"
16
+ asset pack, re-hosted on the HF Hub for fast/reliable download (upstream is a UTexas Box
17
+ link that can be slow or unreachable from some networks).
18
+
19
+ Pulled by RoboCasa's `download_kitchen_assets.py --type objs_lw` (and required by the GR00T
20
+ `robocasa365` sim setup, which downloads `tex tex_generative fixtures_lw objs_lw
21
+ objs_objaverse objs_aigen`). Companion to
22
+ [`IIFAN/robocasa365-lightwheel-fixtures`](https://huggingface.co/datasets/IIFAN/robocasa365-lightwheel-fixtures).

36
+ Verify after download:
37
+ ```bash
38
+ echo "a1db739b0e80fc4d56d4be27d89dba3aa60000e9648c5607874700e0f14b7955 objects_lightwheel.zip" | sha256sum -c
39
+ ```
40
+
41
+ ## Use it as a drop-in for `download_kitchen_assets.py`
42
+
43
+ The official script extracts this zip into `<robocasa>/robocasa/models/assets/objects/`
44
+ (creating `models/assets/objects/lightwheel/`):
45
+
46
+ ```bash
47
+ hf download IIFAN/robocasa365-lightwheel-objects objects_lightwheel.zip \
48
+ --repo-type dataset --local-dir /tmp/rc365
49
+
50
+ ROBOCASA=external_dependencies/robocasa365 # or external_dependencies/robocasa
51
+ unzip -q /tmp/rc365/objects_lightwheel.zip -d "$ROBOCASA/robocasa/models/assets/objects/"
52
+ # -> $ROBOCASA/robocasa/models/assets/objects/lightwheel/
53
+ ```
54
+
55
+ The remaining asset types (`tex`, `tex_generative`, `objs_objaverse`, `objs_aigen`) are NOT
56
+ in this repo — mirror them the same way from the Box links in `box_links_assets.json` if needed.
