Coffee Capsule Pickup — Trossen AI Bimanual (TsFile)

Apache TsFile version of allday-technology/coffeeCapsulePickup_LA_CLRHW_fryerTable_2.

Overview

A LeRobot (v2.1) teleoperation dataset recorded on a Trossen AI stationary bimanual robot performing the task "pick up a coffee capsule with the left arm." Each episode is a continuous trajectory of synchronized 14-DOF joint states and commanded actions (two 7-DOF arms) sampled at 30 Hz.

Robot: Trossen AI stationary bimanual (robot_type = trossen_ai_stationary, 14 degrees of freedom).
Episodes: 39 trajectories (see the exclusion note below).
Frames: 22,142 time steps.
Tasks: 1 — "pick up a coffee capsule with the left arm".
Sampling rate: 30 fps.

Schema (TsFile structure)

Time (INT64, milliseconds) — per-frame timestamp, restarting at 0 for each episode (round(timestamp * 1000)).
episode_index (TAG) — trajectory id (original source indices; the excluded episodes' indices are absent). Query one episode with WHERE episode_index=0.
task_index (TAG) — task id (always 0 here; the single task).
frame_index (FIELD, INT64) — frame counter within the episode.
sample_index (FIELD, INT64) — the source global index.
action_0 .. action_13 (FIELD, FLOAT) — commanded 14-DOF joint positions (left arm + right arm).
observation_state_0 .. observation_state_13 (FIELD, FLOAT) — measured 14-DOF joint positions.

The source vector columns action[14] and observation.state[14] are flattened to single-precision FLOAT columns. The source timestamp column is dropped because it equals Time / 1000 seconds.

Excluded episodes

The source dataset ships meta/ignore_episodes.json marking 9 episodes as bad: [1, 4, 29, 34, 35, 36, 37, 44, 45]. Following the authors' intent, these 9 episodes are excluded from this TsFile — 39 of the original 48 episodes are included. Because episode_index keeps its original value, those 9 indices simply do not appear.

Usage

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