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:

observation.images.image: 136 MP4 files
observation.images.wrist_image: 136 MP4 files
observation.images.frontview_image: 136 MP4 files
observation.images.sideview_image: 136 MP4 files

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()
