idreesrazak_record_test (TsFile)

Apache TsFile version of idreesrazak/record-test.

Overview

A LeRobot teleoperation dataset recorded with an SO-101 follower arm. 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 captures one manipulation task.

Task: "Grab an object and drop it in the bin".
Scale: 54 episodes, 24,163 frames at 30 fps, 1 task.
Robot: so101_follower (6-DoF arm + gripper).
Modalities converted: 6-D scalar observation.state and 6-D scalar action, plus frame_index/sample_index. The two camera video streams (observation.images.front, observation.images.top) 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_5 (FLOAT) — commanded joint/gripper positions.
observation_state_0 .. observation_state_5 (FLOAT) — measured joint/gripper positions.

Vector columns are flattened element-wise (observation.state → observation_state_0..5, action → action_0..5). 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/idreesrazak_record_test.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())
