LIBERO Plus Spatial Camera All Sawyer Failures TsFile

This dataset is an Apache TsFile conversion of LSY-lab/libero_plus_spatial_camera_all_sawyer_failures, a LeRobot v3.0 Sawyer manipulation dataset covering ten LIBERO-Plus spatial-camera tasks. The source repository is published by LSY-lab; its commits identify Maximilian Christof (max-chr) as the original uploader.

Source Dataset and Attribution

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

TsFile Schema

  • TIME: Time (INT64 milliseconds)
  • TAG/device columns: episode_index, task_index
  • Scalar FIELD columns: frame_index, sample_index
Source vector Width Flattened FLOAT fields
observation.state 8 observation_state_0 ... observation_state_7
observation.states.ee_state 6 observation_states_ee_state_0 ... observation_states_ee_state_5
observation.states.joint_state 7 observation_states_joint_state_0 ... observation_states_joint_state_6
observation.states.gripper_state 2 observation_states_gripper_state_0 ... observation_states_gripper_state_1
action 7 action_0 ... action_6

Vector names preserve the source prefix, replace . with _, and append the element index. The source index column is renamed to sample_index.

Videos and Frame Alignment

The original videos/ tree contains 544 MP4 files (314,489,697 bytes), with 136 files for each 256x256 AV1 stream:

Videos are not included in the TsFile upload. Align numeric rows with source video frames using episode_index and frame_index; source episode metadata under meta/episodes/ preserves each stream's file indexes and timestamp range.

Minimal Read Example

from tsfile import TsFileReader

reader = TsFileReader("data/lsy_lab_libero_plus_spatial_camera_all_sawyer_failures.tsfile")
table_name = "lsy_lab_libero_plus_spatial_camera_all_sawyer_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()
