Format and splits

Each task under State/ or Order/ 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 v1.3.0 · Split v1.3.0 · 778 train / 198 val. Explicit sample lists in manifest.json are authoritative. All existing 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.

Order recovery addition

O15 adds 35 real-robot trajectories and 105 videos from the 2026-11-03 two-cup recovery task. It belongs to Order, with task_variant=recovery. The State collection remains 19 tasks / 941 trajectories; Order contains 1 task / 35 trajectories. Existing files and frozen splits are unchanged. O15 adds 28 train / 7 val samples.

Flip the left cup over and back. While handling the right cup, knock over the left cup, restore it, then finish flipping the right cup over and back. The user confirmed the actual two-cup setup. The corrected text is stored in source_instruction; the original three-cup text remains in recorded_source_instruction. Raw source recordings are unchanged.

All 35 reviewed trajectories are retained and unannotated. No recovery-stage boundaries or success labels are inferred. The 105 new videos preserve 1280×720 at 30 FPS and exact source frame boundaries, verified by full decoded-pixel, frame-count and timestamp checks.
