omy_f3m_multi_disconnect_0 (TsFile)

Apache TsFile version of AivexRoboticsGroup/omy_f3m_multi_Disconnect-0.

Overview

A LeRobot demonstration dataset recorded on an omy_f3m_multi bimanual robot. Each record is one control frame of a single demonstration episode: the commanded action, the measured robot state, and the frame/task bookkeeping. The dataset covers one disconnection task.

Task: "Disconnect the usb".
Scale: 150 episodes, 86,923 frames at 30 fps, 1 task.
Robot: omy_f3m_multi (14-D action and observation state: both arms/hands).
Modalities converted: the 14-D scalar observation.state and 14-D scalar action, plus frame_index/sample_index. The three camera video streams (observation.images.left_cam_wrist, observation.images.right_cam_wrist, observation.images.third_view) are not included; see below.

Schema (TsFile structure)

Time (INT64, milliseconds) — round(timestamp * 1000), restarting at 0 for each episode.
episode_index (TAG) — episode/device dimension. Query one episode with WHERE episode_index=0.
task_index (TAG) — task id (single task, always 0).
frame_index, sample_index (INT64) — source frame number and global source row index.
action_0 .. action_13 (FLOAT) — commanded joint positions.
observation_state_0 .. observation_state_13 (FLOAT) — measured joint positions.

Vector columns are flattened element-wise (observation.state → observation_state_0..13, action → action_0..13). The source timestamp column is not retained because it equals Time ÷ 1000 seconds.

Usage

Install the Apache TsFile Python SDK (pip install tsfile) and read a converted file:

from pathlib import Path
from tsfile import TsFileReader

path = Path("data/omy_f3m_multi_disconnect_0.tsfile")
with TsFileReader(str(path)) as reader:
    schemas = reader.get_all_table_schemas()
    print("tables:", list(schemas))
    table_name = next(iter(schemas))
    table = schemas[table_name]
    columns = [column.get_column_name() for column in table.get_columns()]
    print("columns:", columns)
    field_names = [
        column.get_column_name()
        for column in table.get_columns()
        if column.get_column_name() not in {"Time", "time"}
    ]
    if field_names:
        with reader.query_table(table_name, field_names[:3], batch_size=1024) as result:
            batch = result.read_arrow_batch()
            if batch is not None:
                print(batch.to_pandas().head())
