tote_bag_400

This dataset was converted from Ksato5044/tote_bag_400 to Apache TsFile format.

Dataset Description

The original dataset is a LeRobot-format robot dataset for the task "Pick up the bag on the floor".

  • Modalities: Time-series. The original dataset also includes video streams.
  • Robot type: hsr
  • Codebase version: LeRobot v2.0
  • Recording frequency: 10 Hz
  • Split: train (0:400)
  • Scale: 400 episodes, 102,629 frames, 1 task, 800 source videos
  • Source data path: data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.parquet
  • Source video path: videos/chunk-{episode_chunk:03d}/{video_key}/episode_{episode_index:06d}.mp4

Source Dataset

  • Original dataset: Ksato5044/tote_bag_400
  • Authors: Ksato5044
  • Task: Pick up the bag on the floor
  • License: Not declared in the source dataset metadata.

TsFile Conversion

The numeric robot state/action/time/task data was converted into one TsFile:

data/tote_bag_400.tsfile

Conversion details:

  • All 400 source episodes are stored in one TsFile table named tote_bag_400.
  • episode_index and task_index are TsFile TAG columns. Query a single episode with WHERE episode_index=N.
  • Time = round(timestamp * 1000) in milliseconds. The source timestamp column is not retained because it equals Time / 1000 seconds.
  • frame_index is kept. Source index is renamed to sample_index, and next.done is renamed to next_done.
  • Vector columns are flattened by preserving the source column name, replacing . with _, and appending the element index.
  • Values from flattened vector columns are stored as single-precision FLOAT.
  • The converted TsFile contains 102,629 rows and 104 columns including Time, TAG columns, and FIELD measurements.

Flattened vector features:

  • observation.state[8] -> observation_state_0..observation_state_7
  • observation.wrench.wrist[60] -> observation_wrench_wrist_0..observation_wrench_wrist_59
  • action.absolute[8] -> action_absolute_0..action_absolute_7
  • action.relative[11] -> action_relative_0..action_relative_10
  • action.arm[5] -> action_arm_0..action_arm_4
  • action.gripper[1] -> action_gripper_0
  • action.head[2] -> action_head_0..action_head_1
  • action.base[3] -> action_base_0..action_base_2

Schema roles:

  • TIME: Time in milliseconds.
  • TAG: episode_index, task_index.
  • FIELD: frame_index, sample_index, next_done, and the flattened robot observation/action measurements.

Dropped or omitted source fields:

  • timestamp is dropped because it is represented by Time.
  • observation.image.head and observation.image.hand are video features and are not converted into TsFile columns.
  • MP4 videos are not included in this repository. They remain in the original dataset under videos/.

The mirrored meta/info.json records the original video path and includes a tsfile_conversion section describing the converted schema, row count, TAG columns, dropped timestamp column, omitted video features, and time mapping.

Read Example

from tsfile import TsFileReader

path = "data/tote_bag_400.tsfile"

with TsFileReader(path) as reader:
    table = reader.get_all_table_schemas()["tote_bag_400"]
    columns = [c.get_column_name() for c in table.get_columns()]
    print(columns[:10])
