roarm_m3_test

This dataset is converted from dudulrx0601/roarm_m3_test to Apache TsFile format.

Modalities: Time-series. The original dataset also contains laptop and phone camera video streams, which remain in the source Hugging Face dataset and are not included in this converted repository.

Source Dataset

  • Original dataset: dudulrx0601/roarm_m3_test
  • Format: LeRobot v2.0
  • Robot type: unknown
  • License: apache-2.0
  • Scale: 50 episodes, 4,739 frames, 1 task (pick), 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

Converted Files

  • TsFile data: data/roarm_m3_test.tsfile
  • Mirrored metadata: meta/
  • Rows in TsFile: 4,739
  • Time precision: milliseconds

Schema

Time is synthesized as round(timestamp * 1000) and restarts per episode.

TAG columns:

  • episode_index
  • task_index

FIELD columns:

  • frame_index
  • sample_index renamed from source index
  • next_done renamed from source next.done
  • observation_state_0 through observation_state_5, flattened from observation.state[6]
  • action_0 through action_5, flattened from action[6]

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

Conversion Notes

  • The source timestamp column is not retained as a separate field because it is redundant with Time / 1000 seconds.
  • Source video streams observation.images.laptop and observation.images.phone are not uploaded here. Use the original dataset videos: https://huggingface.co/datasets/dudulrx0601/roarm_m3_test/tree/main/videos
  • meta/info.json is mirrored from the source and updated to describe the converted TsFile schema, original video path, row count, TAG columns, flattened features, renamed fields, and video policy.
  • Aside from the redundant timestamp field and omitted video streams, no rows or numeric time-series fields are intentionally dropped.

Read Example 

# Read data/roarm_m3_test.tsfile with the Apache TsFile Java/Python SDK.
# Query one episode with a predicate such as:
# WHERE episode_index = 0
