Coin Add More TsFile

This dataset is a TsFile conversion of the LeRobot dataset Jinyu220/coin_add_more. It keeps the numeric robot state, action, eye, pose, frame, episode, and task data in one TsFile table. Video files are not mirrored in this converted repository.

Source Dataset

Original dataset: Jinyu220/coin_add_more
Authors/organization: Jinyu220
License: apache-2.0
LeRobot codebase version: v2.1
Robot type: not specified in source metadata
Modalities: Time-series
Source split: train: 0:100
Scale: 100 episodes, 43,297 frames, 2 tasks, 500 videos, 1 chunk
Sampling rate: 33 fps
Tasks: put_coinv2; coin_add_more
Source video streams: observation.images.left_eye_cam, observation.images.right_eye_cam, observation.images.wrist_cam_right, observation.images.overhead_cam, observation.images.worms_eye_cam
Video format: 480x640x3, AV1, 33 fps
Source videos: videos/

TsFile Data

TsFile path: data/coin_add_more.tsfile
Table name: coin_add_more
Rows: 43,297
Episode/task device groups: episode_index + task_index
Mirrored metadata: meta/episodes.jsonl, meta/episodes_stats.jsonl, meta/info.json, meta/tasks.jsonl

Schema

Column	TsFile role	Type	Notes
`Time`	TIME	INT64	Milliseconds, computed as `round(timestamp * 1000)`
`episode_index`	TAG	INT64	Source episode identifier
`task_index`	TAG	INT64	Source task identifier
`frame_index`	FIELD	INT64	Source frame index, retained
`sample_index`	FIELD	INT64	Source `index`, renamed to avoid ambiguity
`observation_state_0` ... `observation_state_13`	FIELD	FLOAT	Flattened source `observation.state` vector
`action_0` ... `action_13`	FIELD	FLOAT	Flattened source `action` vector
`left_eye_0` ... `left_eye_1`	FIELD	FLOAT	Flattened source `left_eye` vector
`right_eye_0` ... `right_eye_1`	FIELD	FLOAT	Flattened source `right_eye` vector
`right_arm_pose_0` ... `right_arm_pose_15`	FIELD	FLOAT	Flattened source `right_arm_pose` vector
`middle_arm_pose_0` ... `middle_arm_pose_15`	FIELD	FLOAT	Flattened source `middle_arm_pose` vector

Conversion Notes

Time is synthesized from the source timestamp column as integer milliseconds.
The source timestamp column is dropped because it is redundant with Time / 1000 seconds.
The source index column is renamed to sample_index.
Vector columns are flattened by preserving the full source name, replacing . with _, and appending the element index.
episode_index and task_index are stored as TsFile TAG columns, so each episode/task pair is queryable as a device grouping.
Source videos are intentionally omitted from this upload; use the original dataset for video playback and frame alignment.
No numeric rows were intentionally dropped during conversion.

Validation

pipeline.py validate passed for data/coin_add_more.tsfile.
TsFile readback reported 43,297 rows, matching the staged Parquet row count.
Readback row distribution by task tag: task 0 has 35,324 rows, task 1 has 7,973 rows.
