LIBERO Plus Goal Camera All Kinova3 Failures (TsFile)

This repository is an Apache TsFile conversion of LSY-lab/libero_plus_goal_camera_all_kinova3_failures, a LeRobot v3.0 dataset for Kinova3 manipulation trajectories. The source repository is published by the Learning Systems Lab (LSY-lab) and the source upload is attributed to Maximilian Christof (max-chr). The source card declares the Apache-2.0 license and does not provide a dataset-specific paper citation; the tasks are part of the LIBERO-Plus project.

Source dataset and videos

  • Source dataset: https://huggingface.co/datasets/LSY-lab/libero_plus_goal_camera_all_kinova3_failures
  • Source revision inspected: 23c505b64fcdeedb558f478776c79aea4c9de4a9
  • Robot: kinova3; LeRobot codebase: v3.0; sampling rate: 20 fps
  • Source frame layout: data/chunk-{chunk_index:03d}/file-{file_index:03d}.parquet
  • Source video layout: videos/{video_key}/chunk-{chunk_index:03d}/file-{file_index:03d}.mp4
  • Camera streams: observation.images.image, observation.images.wrist_image, observation.images.frontview_image, and observation.images.sideview_image (256×256 RGB, AV1, 20 fps).

The TsFile repository intentionally does not include videos/. Retrieve videos from the original Hugging Face video tree. Align a video with numeric rows using episode_index and frame_index; meta/episodes/chunk-000/file-000.parquet contains the per-stream chunk/file and timestamp ranges.

Converted artifact

  • TsFile: data/lsy_lab_libero_plus_goal_camera_all_kinova3_failures.tsfile
  • Table: lsy_lab_libero_plus_goal_camera_all_kinova3_failures
  • Split: train
  • Source shards: 1 Parquet file; merged output: 1 TsFile
  • Rows: 56,874; episodes: 258; tasks: 10
  • Source Parquet size: 10,202,862 bytes; TsFile size: 7,033,403 bytes (smaller after encoding/compression)

Schema

Time is an INT64 millisecond timestamp computed as round(timestamp * 1000). The source timestamp is then dropped because it is redundant with Time / 1000. Time remains monotonic within each (episode_index, task_index) device segment; the source episode_index and task_index values are preserved as TsFile TAG columns.

Role Columns
TIME Time (INT64, ms)
TAG/device episode_index (INT64), task_index (INT64)
FIELD metadata frame_index, sample_index (renamed from index)
FIELD vectors observation_state_0..7, observation_states_ee_state_0..5, observation_states_joint_state_0..6, observation_states_gripper_state_0..1, action_0..6 (FLOAT32)

Vector columns are flattened row-major to scalar FLOAT fields. Source dots are replaced with underscores: for example, observation.states.ee_state becomes observation_states_ee_state_0_5. No numeric rows or state/action dimensions are dropped; only timestamp is dropped and index is renamed.

The source contains some IEEE-754 NaN values in state/action dimensions (preserved in the TsFile); these are data values rather than dropped rows.

TsFile encoding and compression

The table writer uses the requested compact policy:

  • FLOAT/DOUBLE → GORILLA + LZ4
  • INT32/INT64 → TS_2DIFF + LZ4
  • TIME → TS_2DIFF + LZ4
  • BOOLEAN (if present in a future source revision) → RLE + LZ4
  • TAG values → TsFile table-model device/TAG segments

The staged Parquet and final TsFile were read back with the TsFile Python SDK. Metadata and query readback both report 56,874 rows, and the converted schema contains 1 TIME, 2 TAG, and 32 FIELD columns.

Task index mapping

  1. put the wine bottle on the rack
  2. open the middle layer of the drawer
  3. put the wine bottle on the top of the drawer
  4. put the bowl on the plate
  5. put the bowl on the top of the drawer
  6. open the top layer of the drawer and put the bowl inside
  7. push the plate to the front of the stove
  8. put the bowl on the stove
  9. put the cream cheese on the bowl
  10. turn on the stove

Minimal read example

from tsfile import TsFileReader

path = "data/lsy_lab_libero_plus_goal_camera_all_kinova3_failures.tsfile"
reader = TsFileReader(path)
table_name = "lsy_lab_libero_plus_goal_camera_all_kinova3_failures"
schema = reader.get_all_table_schemas()[table_name]
columns = [c.get_column_name() for c in schema.get_columns()
           if c.get_column_name() != "Time"]

with reader.query_table(table_name, columns, batch_size=65536) as result:
    batch = result.read_arrow_batch()

The dataset-specific YAML configuration and converter are kept locally under D:/code/config/ and D:/code/scripts/; validation reports are local conversion artifacts and are not part of the TsFile upload set.
