# simboxpushtest (TsFile)

Apache TsFile version of [`kumarhans/simBoxPushTest`](https://huggingface.co/datasets/kumarhans/simBoxPushTest).

## Overview

A [LeRobot](https://github.com/huggingface/lerobot) robot-manipulation dataset. The source card is auto-generated ("This dataset was created using LeRobot") and does not add a free-text description; the facts below are taken from the source `meta/info.json`.

- **Robot:** so100
- **Episodes:** 31
- **Sampling rate:** 30 fps
- **Splits:** a single `train` split

## Schema (TsFile structure)

- **Time** (INT64, milliseconds) — `round(timestamp * 1000)`; the source `timestamp` column (seconds) is dropped because it equals `Time / 1000`.
- **episode_index** (TAG), **task_index** (TAG) — device dimensions; query one episode with `WHERE episode_index = <n>`.
- **frame_index** (FIELD, INT64), **sample_index** (FIELD, INT64, from the source `index`) — per-frame bookkeeping.
- Vector columns (single-precision FLOAT, source name with `.` → `_` and an element index appended):
  - action → `action_0`..`action_5` (FLOAT)
  - observation.state → `observation_state_0`..`observation_state_5` (FLOAT)

Camera video streams are **not** included in this repository; see the original dataset for the videos: https://huggingface.co/datasets/kumarhans/simBoxPushTest (`videos/` directory). The numeric state/action series are complete; join with the original videos via `episode_index` + `frame_index`.

## Usage

Install the Apache TsFile Python SDK (`pip install tsfile`) and read a converted file:

```python
from pathlib import Path
from tsfile import TsFileReader

path = Path("data/simboxpushtest.tsfile")
with TsFileReader(str(path)) as reader:
    schemas = reader.get_all_table_schemas()
    print("tables:", list(schemas))
    table_name = next(iter(schemas))
    table = schemas[table_name]
    columns = [column.get_column_name() for column in table.get_columns()]
    print("columns:", columns)
    field_names = [
        column.get_column_name()
        for column in table.get_columns()
        if column.get_column_name() not in {"Time", "time"}
    ]
    if field_names:
        with reader.query_table(table_name, field_names[:3], batch_size=1024) as result:
            batch = result.read_arrow_batch()
            if batch is not None:
                print(batch.to_pandas().head())
```
