Format and splits
Each task under State/ retains its original metadata.json, metadata.jsonl, videos and,
when present, stage annotations. Paths in each trajectory index are task-relative. Resolution,
frame rate and available camera views are preserved per trajectory; they are not uniform
across all source datasets. All views of a trajectory share its frozen split.
Dataset v1.4.2 · Split v1.4.2 · 750 train / 191 val. Explicit sample lists in manifest.json are authoritative. All surviving assignments are preserved.
Sources and annotation status
S01–S10 are copied from MINT-SJTU/ProPriMem: 618 simulation trajectories with their original stage annotations. S01–S06 originate from TianxingChen/RMBench; S07–S10 originate from htrbao/LIBERO-MEM_lerobot. Original source links, instructions, hashes and domain labels remain in each trajectory index. The MINT repository is unchanged by this copy.
S11–S19 contain 323 real-robot PiperX trajectories collected on 2026-10-31, 2026-11-02 and
2026-11-03, with 969 videos at 1280×720 and 30 FPS. These recordings are unannotated:
has_annotation=false; stage boundaries and task-success labels are not inferred. The environment
camera is main_view, with wrist cameras left_view and right_view. Task names have no State
prefix. Raw robot state/action Parquet files are not included.
Selection and validation
User-reviewed exclusions remain unchanged: piggy-bank batch 20261031_153227 #3/#15/#16 and
batch 20261031_161309 #18/#19/#20; tea batch 20261103_134047 #0/#1; upside-down-cup batch
20261103_142808 #0. These refer to original source episode indices. The bottle task describes
three bottles. The test-tube task combines valid batches of 11 + 3 + 35 trajectories.
The 969 PiperX videos are frame-exact H.264 stream-copy cuts, checked by full decoding against source frame counts, timestamps and decoded YUV pixels. Imported State files are copied without re-encoding or changing annotations; hashes and frozen split assignments are verified.
Moved tasks
O15 (two-cup recovery) and S20 (repeated pouring) are available in ProPriMem Recover Trajectories, including their original train/validation assignments.
