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 sourcemeta/declares only 42 episodes (info.jsontotal_episodes=42/total_frames=28964;episodes.jsonlhas 42 lines). Episodes 42–45 (4,497 frames) are present and valid on disk but missing frommeta. This TsFile includes all 46 episodes; the mirroredmeta/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
indexcolumn. - 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.
