+# so100_test_25 (TsFile)
+
+Apache TsFile version of [`douzi999/so100_test_25`](https://huggingface.co/datasets/douzi999/so100_test_25).
+
+## 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:** 40
+- **Frames:** 19701
+- **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_11` (FLOAT)
+  - observation.state → `observation_state_0`..`observation_state_11` (FLOAT)
+
+Camera video streams are **not** included in this repository; see the original dataset for the videos: https://huggingface.co/datasets/douzi999/so100_test_25 (`videos/` directory).
+
+## Usage
+
+Read the `.tsfile` files with the Apache TsFile Java or Python SDK.
