-# dagger_final_1_21 (TsFile)
-
-Apache TsFile version of the LeRobot dataset
-[`lerobot-data-collection/dagger_final_1_21`](https://huggingface.co/datasets/lerobot-data-collection/dagger_final_1_21).
-
-## Overview
-
-Bimanual openarms-follower demonstrations (LeRobot v3.0).
-
-- **Robot:** openarms_follower (bimanual)
-- **Episodes:** 1
-- **Frames:** 841
-- **Sampling rate:** 30 fps
-- **Tasks:** 1
-
-## Schema (TsFile structure)
-
-- **Time** (INT64, milliseconds) — `round(timestamp * 1000)`, restarting per episode.
-- **episode_index / task_index** (TAG) — the device dimension. Query a single episode with
-  `WHERE episode_index=N`.
-- **FIELD** — `frame_index`, `sample_index`, and the flattened state/action vectors
-  (`observation_state_0..15`, `action_0..15`) as single-precision FLOAT.
-
-The robot's the left_wrist / right_wrist / base camera streams are time-series-irrelevant and **not uploaded** to this repository;
-get them from the original dataset (its `videos/` directory). The source `meta/` is mirrored here.
-
-## Usage
-
-Read the `.tsfile` files with the Apache TsFile Java or Python SDK.
-
-## Source & license
