RoboDyna v2 — FastWAM training bundle
Author: Rui Heng Yang
Training-ready bundle for the LeRobot v2.1 half of
RoboDyna/robodyna-benchmark-v2
(81 task-condition combos, 4,050 episodes, dual-arm ur5-wsg, 16.67 Hz), plus the
FastWAM preprocessing artifacts computed from it. Everything ships as one tar
archive split into ≤45 GiB parts (robodyna_v2_bundle.tar.part-NN);
parts.sha256 holds the part checksums.
The extracted tree:
| Path | Content |
|---|---|
lerobot/<task>/<condition>/ |
Unmodified LeRobot v2.1 datasets (81 combos) |
dataset_stats.json |
Action/state normalization stats (z-score fields + min/max/q01/q99), computed over the 99% train split |
text_embeds_cache/ |
UMT5 text-embedding cache, 35 prompts, context_len=128 |
fastwam_vae_cache_wan22_bf16/ |
Wan2.2-TI2V-5B VAE latent cache: 1,348,216 samples, [48,3,24,20] bf16, whole latents.bf16 (186,377,379,840 bytes), built with video_backend=pyav, num_frames=33, action_video_freq_ratio=4 |

Notes
- Training must pin
video_backend=pyav: latent-cache compatibility compares the backend recorded at build time. - The VAE cache
manifest.jsonrecords the full identity (VAE sha256, preprocess spec, sample count 1,348,216). - The upstream benchmark's
annotations/and HDF5 half are intentionally not bundled; get them from the original dataset.
