box_in_bin_test

This dataset is a TsFile conversion of rtsmc/box_in_bin_test, a LeRobot SO-101 follower robot dataset.

Source Dataset

  • Original dataset: rtsmc/box_in_bin_test
  • Original license: apache-2.0
  • Robot type: so101_follower
  • Modalities: Time-series
  • Source sampling rate: 30 fps
  • Source scale: 31 episodes, 13,602 frames, 1 task
  • Source videos: 31 videos in the original dataset under videos/

The source task is:

  • task_index=0: Put the box in the bin

TsFile Conversion

The converted dataset stores the numeric robot time-series data in one TsFile:

  • data/box_in_bin_test.tsfile

Conversion summary:

  • Rows: 13,602
  • Episodes: 31
  • Time precision: milliseconds
  • Table name: box_in_bin_test
  • TAG columns: episode_index, task_index
  • Time mapping: Time = round(timestamp * 1000)
  • Dropped source column: timestamp, because it is represented by Time / 1000
  • Renamed source column: index to sample_index
  • Omitted source video feature: observation.images.front

The meta/ directory is mirrored from the source dataset, with meta/info.json updated to describe the converted TsFile artifact and the video policy. Videos are not included in this converted repository; use the original dataset if frame-aligned videos are needed.

Schema

Time is the TsFile time column in milliseconds. episode_index and task_index are TAG columns. Remaining columns are FIELD measurements:

  • frame_index
  • sample_index
  • action_0 through action_5
  • observation_state_0 through observation_state_5

The 6 action and observation-state dimensions follow the source joint order:

  • shoulder_pan.pos
  • shoulder_lift.pos
  • elbow_flex.pos
  • wrist_flex.pos
  • wrist_roll.pos
  • gripper.pos

Usage

Read the TsFile with Apache TsFile tools or SDKs. Example path:

data/box_in_bin_test.tsfile

To inspect a single episode in SQL-style tools, filter by the TAG:

SELECT *
FROM box_in_bin_test
WHERE episode_index = 0;
