LIBERO Plus Goal Lighting All IIWA Failures TsFile

This is an Apache TsFile conversion of LSY-lab/libero_plus_goal_lighting_all_iiwa_failures, a LeRobot v3.0 IIWA manipulation dataset containing successful and failed attempts for nine LIBERO-Plus goal-lighting task instructions. The source repository is published by LSY-lab; all four source commits, including the initial upload, are authored by Maximilian Christof (max-chr).

Source Dataset and Attribution

Original dataset: LSY-lab/libero_plus_goal_lighting_all_iiwa_failures
Source organization: LSY-lab
Original uploader/author: Maximilian Christof (max-chr)
License: Apache-2.0
Robot type: iiwa; LeRobot codebase: v3.0
Sampling rate: 20 fps; source split: train: 0:186
The source card provides no dataset-specific paper citation or BibTeX entry.
Source numeric 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

Source Videos

The original videos/ tree contains 744 MP4 files (321.77 MiB), with 186 files for each 256x256 RGB AV1 stream at 20 fps and no audio:

observation.images.image - 186 MP4 files
observation.images.wrist_image - 186 MP4 files
observation.images.frontview_image - 186 MP4 files
observation.images.sideview_image - 186 MP4 files

Videos are not included in this TsFile dataset. Retrieve them from the original videos/ tree. Align rows to MP4 frames using episode_index and frame_index; meta/episodes/chunk-000/file-000.parquet stores each stream's chunk/file index and timestamp range.

Minimal Read Example

from tsfile import TsFileReader

reader = TsFileReader("data/lsy_lab_libero_plus_goal_lighting_all_iiwa_failures.tsfile")
table_name = "lsy_lab_libero_plus_goal_lighting_all_iiwa_failures"
columns = [
    "episode_index", "task_index", "frame_index", "sample_index",
    "action_0", "observation_state_0",
]
with reader.query_table(table_name, columns, batch_size=65536) as result:
    batch = result.read_arrow_batch()
    print(batch.to_pandas().head())
reader.close()
