# so100_nut_test_11 (TsFile)

Apache TsFile version of [`356c/so100_nut_test_11`](https://huggingface.co/datasets/356c/so100_nut_test_11).

## Overview

A [LeRobot](https://github.com/huggingface/lerobot) robot-manipulation dataset — a nut pick-and-place manipulation task recorded with a SO-100 arm. 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:** SO-100
- **Episodes:** 100
- **Frames:** 38691
- **Sampling rate:** 30 fps
- **Tasks:** 1
- **Splits:** a single `train` split (`0:100`)

## 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):
  - observation.state → `observation_state_0`..`observation_state_5` (FLOAT)
  - action → `action_0`..`action_5` (FLOAT)

Camera video streams are **not** included in this repository; see the original dataset for the videos: https://huggingface.co/datasets/356c/so100_nut_test_11 (`videos/` directory).

## Usage

Read the `.tsfile` files with the Apache TsFile Java or Python SDK.
