Remove Green Duck (TsFile)

Apache TsFile version of KuphDev/remove_green_duck.

Overview

This dataset was created using LeRobot. It contains teleoperated demonstrations on an SO-class follower arm (robot_type = so_follower, 6 DoF) for one task: "Remove green duck from target". Each episode records joint state and commanded action vectors over time.

Modalities: Time-series.
Episodes: 60 demonstrations of one task.
Frames: 53,522 timesteps total, recorded at 30 fps.
Robot: SO follower arm, 6 joints including gripper.
Source format: LeRobot v3.0 Parquet plus video metadata.
Converted file: data/kuphdev_remove_green_duck.tsfile.

Schema

Time (TIME, INT64, milliseconds): per-frame timestamp, synthesized as round(timestamp * 1000). Time restarts at 0 for each episode.
episode_index (TAG, INT64): demonstration id, values 0 through 59.
task_index (TAG, INT64): task id, always 0 in this dataset.
frame_index (FIELD, INT64): frame number within each episode.
sample_index (FIELD, INT64): renamed from the source global index column.
observation_state_0 .. observation_state_5 (FIELD, FLOAT): measured joint positions.
action_0 .. action_5 (FIELD, FLOAT): commanded joint targets.

The 6 channels of observation.state and action are, in source order: shoulder_pan.pos, shoulder_lift.pos, elbow_flex.pos, wrist_flex.pos, wrist_roll.pos, and gripper.pos.

Conversion Notes

Source data/chunk-*/*.parquet files were merged into one TsFile table named kuphdev_remove_green_duck.
Source vector columns were flattened without changing their semantic order: observation.state[6] became observation_state_0..observation_state_5, and action[6] became action_0..action_5.
Source episode_index and task_index are TsFile TAG columns. Query a single episode with a predicate such as WHERE episode_index = 0.
Source timestamp was dropped after conversion because it equals Time / 1000 seconds.
Source index was renamed to sample_index.
Source camera video feature observation.images.top is not included in this converted repository. The numeric time-series data can be aligned back to the original videos by episode_index, frame_index, and Time.
The source meta/ directory is mirrored, with meta/info.json updated to describe the converted TsFile schema and video policy.

Usage

Read the .tsfile file with the Apache TsFile Java or Python SDK.

# pip install tsfile
from tsfile import TsFileReader

reader = TsFileReader("data/kuphdev_remove_green_duck.tsfile")
# Example query intent: select one demonstration with WHERE episode_index = 0.

Videos

The original dataset records one camera stream per episode (observation.images.top). These MP4 videos are not included here; retrieve them from the original dataset under KuphDev/remove_green_duck/videos.
