# 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.
