Team 13 Two-Balls Stacking (TsFile)
Converted from roboticshack/team13-two-balls-stacking at pinned revision 7df39c37cad86c865ae9194461160824afd46d4a. Modalities: Time-series.
Dataset description
This LeRobot v2.1 SO100 dataset records demonstrations of stacking two balls on top of each other.
The pinned task instruction is: “Stack the balls on top of each other.”
- Source repository owner/publisher: roboticshack
- License: apache-2.0 (declared by the source card).
- Paper/homepage/citation: no completed paper, homepage, or citation is documented in the pinned source card unless linked above.
Dataset Scale
| Split | Episodes | Tasks | Source trajectory Parquets | TsFile rows | Sampling rate | TsFile files/shards |
|---|---|---|---|---|---|---|
train |
51 | 1 | 51 | 13,476 | 30 Hz | 1 |
The staged Parquet has 13,476 rows and 17 columns including Time; TsFile chunk metadata independently reports the same 13,476 rows.
TsFile schema
| Column | Role | TsFile type | Observed/source range |
|---|---|---|---|
Time |
TIME | INT64 | 0–11,767 ms; restarts per episode |
episode_index |
TAG | STRING | source integer 0–50 |
task_index |
TAG | STRING | source integer 0–0 |
frame_index |
FIELD | INT64 | 0–353 within an episode |
sample_index |
FIELD | INT64 | 0–13,475 globally |
Exact remaining FIELD names/ranges and imported types:
action_0–action_5(FLOAT): main shoulder pan/lift, elbow flex, wrist flex/roll, and gripper actionobservation_state_0–observation_state_5(FLOAT): the corresponding SO100 state
Conversion
- All source episodes in the train split are merged into
data/team13_two_balls_stacking_train.tsfile;episode_indexandtask_indexare TAG dimensions. Time = round(timestamp * 1000)in milliseconds. The sourcetimestampcolumn is omitted because it is redundant withTime / 1000seconds.frame_indexis retained. Sourceindexis retained assample_index.- Every vector is fully flattened: the complete source name is kept,
.becomes_, and element indices are appended. Float vectors are imported as single-precision FLOAT fields. - Other scalar source columns shown above are retained; no trajectory rows are intentionally dropped.
- Source metadata is mirrored for publication, with copied
meta/info.jsonrewritten to describe the converted data path and conversion semantics.
Video policy
The pinned metadata declares 102 source videos across side and RealSense camera streams. MP4 files were not downloaded or uploaded; they remain in the pinned source videos/ tree.
Minimal read example
from tsfile import TsFileReader
reader = TsFileReader("data/team13_two_balls_stacking_train.tsfile")
print(reader.get_all_table_schemas().keys())
reader.close()
