# cable_insertion_3 (TsFile)
Apache TsFile version of [`DistantSky/cable_insertion_3`](https://huggingface.co/datasets/DistantSky/cable_insertion_3).
## Overview
This dataset is a LeRobot v2.1 dataset of a Hessian arm performing cable insertion at 60 fps, with per-episode `prompt` text.
- **Robot:** Hessian (hessian)
- **Scale:** 66 episodes, 19,896 frames, 60 fps
- **Split:** train
- **Cameras (not uploaded):** `video_left`, `video_overhead`, `video_right`
## Schema (TsFile structure)
The TsFile table is named `cable_insertion_3`.
| Role | Columns |
| --- | --- |
| Time | `Time`, INT64 milliseconds |
| TAG | `episode_index`, `task_index` |
| FIELD | `frame_index`, `sample_index` |
| FIELD | `observation_state_0` … `observation_state_13`, FLOAT |
| FIELD | `observation_velocity_0` … `observation_velocity_13`, FLOAT |
| FIELD | `action_0` … `action_13`, FLOAT |
| FIELD | `source_action_time_s` |
| FIELD | `prompt` |
Vector columns are flattened into scalar FLOAT measurements (single precision). The source `index` column is retained as `sample_index`.
## Conversion notes
- `Time = round(timestamp * 1000)` with millisecond precision; time restarts inside each episode, while `episode_index` and `task_index` identify the TsFile device.
- The original `timestamp` field is omitted because it is exactly represented by `Time / 1000`.
- Camera video streams are NOT included in this repository; they remain in the [source videos tree](https://huggingface.co/datasets/DistantSky/cable_insertion_3/tree/main/videos).
- `meta/` is mirrored from the source. Aside from the redundant `timestamp` column and the excluded videos, no source rows or numeric fields are dropped.
## Read example
```python
from tsfile import TsFileReader
with TsFileReader("data/cable_insertion_3.tsfile") as reader:
print(reader.get_all_table_schemas()["cable_insertion_3"])
```
