OpenArm Pick v6 TsFile
This Apache TsFile edition is based on
qualiadev/openarm_pick_v6, a LeRobot v2.1 bimanual robot
manipulation dataset recorded in Isaac Sim through VR teleoperation.
Source and Attribution
- Source repository:
qualiadev/openarm_pick_v6 - Repository publisher:
qualiadev - Original author named by the source card and citation:
AiSaurabhPatil - License: Apache-2.0
- Task: grab the electric screwdriver from the table and drop it inside the box
- Platform: Isaac Sim (NVIDIA Omniverse)
- Control: VR teleoperation with Quest 3
- Robot:
openarm_bimanual; LeRobot version:v2.1 - Split:
train; 100 episodes; 65,190 frames; 1 task; 30 Hz - Duration: about 36.2 minutes
- Source data: 100 shards at
data/chunk-000/episode_{episode_index:06d}.parquet
TsFile Data
- Path:
data/qualiadev_openarm_pick_v6.tsfile - Table:
qualiadev_openarm_pick_v6 - Rows: 65,190
- Episode devices: 100
- Time precision: milliseconds
- Source Parquet size: 3,081,465 bytes
- TsFile size: 1,533,267 bytes
The 100 episode shards are combined into one table. episode_index and
task_index remain the TsFile TAG/device dimensions, so a single episode or
task can be selected through TAG predicates.
Schema
Time = round(timestamp * 1000) milliseconds and restarts at zero for every
episode. Source timestamp is omitted afterward because it equals
Time / 1000 seconds.
TAG columns:
episode_indextask_index
Scalar FIELD columns:
frame_indexsample_index(renamed from sourceindex)
FLOAT FIELD groups:
action[16]->action_0...action_15observation.state[16]->observation_state_0...observation_state_15
For each vector, indexes 0-6 are the left arm joints, index 7 is the left gripper, indexes 8-14 are the right arm joints, and index 15 is the right gripper. Dots in source vector names become underscores. No numeric row, episode, task, or vector dimension is omitted.
Encodings and Compression
- FLOAT/DOUBLE: GORILLA + LZ4
- INT32/INT64: TS_2DIFF + LZ4
- Time: TS_2DIFF + LZ4
- BOOLEAN: RLE + LZ4 (no BOOLEAN FIELD is present)
- TAG: TsFile table/device storage
Videos
Videos are not included in this TsFile repository. The source has 300 frame-aligned AV1 MP4 files (1,152,509,583 bytes, about 1.07 GiB), 480x360, 30 fps, without audio:
Each stream uses
videos/chunk-000/{video_key}/episode_{episode_index:06d}.mp4.
episode_index, frame_index, and meta/episodes.jsonl preserve frame
alignment with the source videos.
Usage
from tsfile import TsFileReader
reader = TsFileReader("data/qualiadev_openarm_pick_v6.tsfile")
with reader.query_table(
"qualiadev_openarm_pick_v6",
["episode_index", "task_index", "frame_index", "sample_index",
"action_0", "observation_state_0"],
batch_size=65536,
) as result:
print(result.read_arrow_batch().to_pandas().head())
reader.close()
