5position

This dataset is a TsFile conversion of DAbraham/5Position, a LeRobot SO100 robot dataset. The original dataset was created using LeRobot.

Source Dataset

Source dataset: DAbraham/5Position
License: apache-2.0
Robot type: SO100
Episodes: 50
Frames: 43,346
Tasks: 1
Sampling rate: 30 fps
Original data path: data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.parquet
Original video path: videos/chunk-{episode_chunk:03d}/{video_key}/episode_{episode_index:06d}.mp4

TsFile Conversion

The numeric frame data was converted to one TsFile:

data/5position.tsfile

All episodes are stored in the same TsFile table, with the original source columns episode_index and task_index declared as TAG columns. To query one episode, filter by episode_index.

Time is generated as round(timestamp * 1000) in milliseconds and restarts per episode. The source timestamp column is dropped because it is represented by Time / 1000 seconds. The source frame_index column is kept.

The source index column is renamed to sample_index.

Vector columns are flattened while preserving the source column name:

action -> action_0 ... action_5
observation.state -> observation_state_0 ... observation_state_5

Flattened vector values are stored as single-precision FLOAT fields.

Schema

Roles in the converted TsFile:

TIME: Time
TAG: episode_index, task_index
FIELD: frame_index, sample_index, action_0 ... action_5, observation_state_0 ... observation_state_5

The converted dataset contains 43,346 rows and 17 columns.

Video Policy

The original dataset contains three video streams:

observation.images.context
observation.images.arm
observation.images.base

Videos are not included in this converted repository. They remain available in the original Hugging Face dataset:

https://huggingface.co/datasets/DAbraham/5Position/tree/main/videos

Metadata

The original meta/ files are mirrored in this repository. meta/info.json is updated so data_path points to data/5position.tsfile, and it includes a tsfile_conversion object documenting the source dataset, converted data path, time mapping, TAG columns, flattened fields, dropped fields, omitted video features, and video alignment policy.
