+ # Move Objects Multitask (TsFile)
23
+
24
+ This dataset is an Apache TsFile conversion of the Hugging Face dataset
25
+ [`villekuosmanen/move_objects_multitask`](https://huggingface.co/datasets/villekuosmanen/move_objects_multitask).
26
+ The source was created with
27
+ [LeRobot](https://github.com/huggingface/lerobot) and contains ARX5 robot
28
+ demonstrations for 58 object-manipulation tasks.
29
+
30
+ Modalities: Time-series. The source repository also contains three synchronized
31
+ camera streams; videos are not included in this converted repository.
32
+
33
+ ## Source Dataset
34
+
35
+ - Original dataset: [`villekuosmanen/move_objects_multitask`](https://huggingface.co/datasets/villekuosmanen/move_objects_multitask)
36
+ - License: `apache-2.0`
37
+ - Current LeRobot metadata version: `v2.1`
38
+ - Robot type: `arx5`
39
+ - Split: `train` (`0:140`)
40
+ - Scale: `140` episodes, `100,760` frames, `58` tasks
41
+ - Sampling rate: `50` fps
42
+ - Source frame files: `140` Parquet files
43
+ - Source video files present in the repository: `420`
44
+ - Camera streams: `3`, each with `140` MP4 files
45
+ - Source data layout: `data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.parquet`
46
+ - Source video layout: `videos/chunk-{episode_chunk:03d}/{video_key}/episode_{episode_index:06d}.mp4`
47
+
48
+ The tasks include picking up or sliding household objects, moving objects to a
49
+ shelf, placing objects in an oven dish or cardboard box, and several composed
50
+ object interactions. The complete mapping from `task_index` 0 through 57 is
51
+ preserved in `meta/tasks.jsonl`.
52
+
53
+ The camera streams are `observation.images.front`,
54
+ `observation.images.left_wrist`, and `observation.images.right_wrist`. Source
55
+ videos are 480 x 640 RGB AV1 at 50 fps and contain no audio.
56
+
57
+ ### Source metadata discrepancy
58
+
59
+ The current source `meta/info.json` declares `total_videos: 432`, while the
60
+ repository file tree contains 420 MP4 files: 140 episodes multiplied by three
61
+ camera streams. The converted metadata preserves both facts as
62
+ `source_metadata_video_count: 432` and `source_video_count: 420`. The source
63
+ README also embeds an older v2.0 snapshot with 103,021 frames; this card uses
64
+ the current v2.1 `meta/info.json` and the 100,760 rows measured across all 140
65
+ source Parquet files.
66
+
67
+ ## Converted File
68
+
69
+ - TsFile: `data/move_objects_multitask_train.tsfile`
70
+ - TsFile table: `move_objects_multitask_train`
71
+ - Converted rows: `100,760`
72
+ - Episodes: `140`
73
+ - Tasks: `58`
74
+ - Time precision: milliseconds
75
+ - TAG columns: `episode_index`, `task_index`
76
+ - File size: `3,355,749` bytes
77
+ - SHA-256: `9cb91a8cb77dd54c49590433765f0d52dff3cbf22638cc888ac40d378e91ae7a`
78
+
79
+ All train episodes are merged into one TsFile. The original `episode_index` and
80
+ `task_index` columns are retained as TAG columns, allowing queries by episode,
81
+ task, or both without synthetic aliases.
82
+
83
+ ## Schema
84
+
85
+ `Time` is computed as `Time = round(timestamp * 1000)` in milliseconds and
86
+ restarts in each episode. At 50 fps, consecutive frames are approximately 20 ms
87
+ apart. The source `timestamp` column is not retained because it is redundant
88
+ with `Time / 1000` seconds. No source rows are dropped.
89
+
90
+ TAG columns:
91
+
92
+ - `episode_index`
93
+ - `task_index`
94
+
95
+ FIELD columns:
96
+
97
+ - `frame_index`
98
+ - `sample_index` (renamed from source `index`)
99
+ - `action_0` through `action_13` (FLOAT)
100
+ - `observation_state_0` through `observation_state_13` (FLOAT)
101
+
102
+ Both source vector features have 14 float32 elements. The source metadata does
103
+ not provide element names, so this conversion preserves their original order
104
+ without inventing semantic labels. Dots in source feature names are replaced
105
+ with underscores before the zero-based element index is appended.
106
+
107
+ ## Video Policy
108
+
109
+ The three source video features are not converted or uploaded. Use the original
110
+ dataset for synchronized videos:
111
+ [`villekuosmanen/move_objects_multitask/videos`](https://huggingface.co/datasets/villekuosmanen/move_objects_multitask/tree/main/videos).
112
+
113
+ Each numeric row retains `episode_index`, `frame_index`, `task_index`, and
114
+ `sample_index`, preserving alignment with the original per-episode videos.
115
+
116
+ ## Metadata
117
+
118
+ The source `meta/` files are mirrored in this repository. `meta/info.json` is
119
+ updated so `data_path` points to
120
+ `data/move_objects_multitask_train.tsfile`. Its `tsfile_conversion` object
121
+ records the source and converted file counts, declared and observed video
122
+ counts, table name, Time formula, TAG columns, row count, feature mappings, and
123
+ frame/video alignment. The converted `total_videos` value is `0`.
124
+
125
+ ## Validation
126
+
127
+ The converted file was compared with all 140 source Parquet files:
128
+
129
+ - source and staged rows: `100,760`
130
+ - source tasks represented: `58`
131
+ - duplicate `(episode_index, task_index, Time)` rows: `0`
132
+ - maximum action-vector difference: `0`
133
+ - maximum observation-state-vector difference: `0`
134
+ - source `index` to converted `sample_index` mismatches: `0`
135
+
136
+ The TsFile is also validated with the project pipeline and read back with the
137
+ TsFile Python SDK before publication.
138
+
139
+ ## Usage
140
+
141
+ ```python
142
+ from tsfile import TsFileReader
143
+
144
+ path = "data/move_objects_multitask_train.tsfile"
145
+ with TsFileReader(path) as reader:
146
+ schemas = reader.get_all_table_schemas()
147
+ table = schemas["move_objects_multitask_train"]
148
+ print([(column.get_column_name(), column.get_category())
149
+ for column in table.get_columns()])
150
+ ```
