- # so100_brick (TsFile)
21
-
22
- Apache TsFile version of [`mldev19/so100_brick`](https://huggingface.co/datasets/mldev19/so100_brick), a LeRobot v2.1 demonstration dataset recorded with an SO-100 arm.
23
-
24
- ## Overview
25
-
26
- This dataset was created using [LeRobot](https://github.com/huggingface/lerobot). It records one SO-100 manipulation task (brick) with per-frame joint state and action vectors, plus two camera streams (`laptop`, `phone`).
27
-
28
- - **Robot:** SO-100 (`so100`)
29
- - **Scale:** 55 episodes, 16,279 frames, 1 task, 30 fps
30
- - **Split:** train
31
-
32
- ## Schema (TsFile structure)
33
-
34
- The TsFile table is named `so100_brick`.
35
-
36
- | Role | Columns |
37
- | --- | --- |
38
- | Time | `Time`, INT64 milliseconds |
39
- | TAG | `episode_index`, `task_index` |
40
- | FIELD | `frame_index`, `sample_index` |
41
- | FIELD | `action_0` `action_5`, FLOAT |
42
- | FIELD | `observation_state_0` … `observation_state_5`, FLOAT |
43
-
44
- The original 6-element `action` and `observation.state` vectors are flattened into scalar FLOAT measurements. The source `index` column is retained as `sample_index`.
45
-
46
- ## Conversion notes
47
-
48
- - `Time = round(timestamp * 1000)` with millisecond precision; time restarts inside each episode, while `episode_index` and `task_index` identify the TsFile device.
49
- - The original `timestamp` field is omitted because it is exactly represented by `Time / 1000`.
50
- - The two camera streams (`observation.images.laptop`, `observation.images.phone`) are video and are NOT included in this repository; they remain in the [source videos tree](https://huggingface.co/datasets/mldev19/so100_brick/tree/main/videos).
51
- - `meta/` is mirrored from the source. Aside from the redundant `timestamp` column and the excluded videos, no source rows or numeric fields are dropped.
52
-
53
- ## Read example
54
-
55
- ```python
56
- from tsfile import TsFileReader
57
-
58
- with TsFileReader("data/so100_brick.tsfile") as reader:
59
- print(reader.get_all_table_schemas()["so100_brick"])
