SO-100 Grab Pen — record-test-11 (TsFile)

Apache TsFile version of Alexisbo/record-test-11.

Overview

Teleoperated demonstrations on an SO-100 follower arm (robot_type = so100_follower, 6 DoF) of a single task: "Grab pen and put in orange box". Each episode records the arm's joint positions (state) and commanded joint targets (action) over time.

Episodes: 46 demonstrations of one task.
Frames: 33,461 timesteps total, recorded at 30 fps.
Robot: SO-100 follower arm (6 joints incl. gripper).
Source format: LeRobot v2.1.

Episode count note: the source data/ directory ships 46 episode files (indices 0–45). The source meta/ declares only 42 episodes (info.json total_episodes=42 / total_frames=28964; episodes.jsonl has 42 lines). Episodes 42–45 (4,497 frames) are present and valid on disk but missing from meta. This TsFile includes all 46 episodes; the mirrored meta/ is left as-is (still describing 42), so prefer the TsFile contents as the source of truth for episode/frame counts.

Schema (TsFile structure)

Time (INT64, milliseconds) — per-frame timestamp, restarts at 0 for each episode (round(timestamp * 1000); ~33 ms apart at 30 fps).
episode_index (TAG) — demonstration id (0–45). Query a single episode with WHERE episode_index=0.
task_index (TAG) — task id (always 0; the dataset has one task).
frame_index (FIELD, INT64) — frame number within the episode.
sample_index (FIELD, INT64) — 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 each vector are the SO-100 joints, in order: shoulder_pan, shoulder_lift, elbow_flex, wrist_flex, wrist_roll, gripper (positions, in degrees).

The source timestamp column is dropped because it equals Time / 1000. Camera videos are not included in this repository (see below).

Usage

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

# pip install tsfile
from tsfile import TsFileReader
reader = TsFileReader("data/alexisbo_record_test_11.tsfile")
# query one episode: WHERE episode_index=0

Videos

The original dataset records two camera streams per episode (observation.images.front, observation.images.side). These MP4 videos are not included here — they are not time-series data. Retrieve them from the original dataset under Alexisbo/record-test-11/videos.
