stack_cubes_flexiv_0801 (TsFile)

Apache TsFile version of Xense/stack-cubes-flexiv-0801.

Overview

This dataset is a LeRobot v3.0 bimanual dataset of a Flexiv Rizon 4 robot stacking cubes.

Robot: bimanual Flexiv Rizon 4 (bi_flexiv_rizon4_rt)
Scale: 170 episodes, 891,288 frames, 30 fps
Split: train
Cameras (not uploaded): head, left_wrist, right_wrist, plus tactile views

Schema (TsFile structure)

The TsFile table is named stack_cubes_flexiv_0801.

Role	Columns
Time	`Time`, INT64 milliseconds
TAG	`episode_index`, `task_index`
FIELD	`frame_index`, `sample_index`
FIELD	`action_0` … `action_19`, FLOAT
FIELD	`observation_state_0` … `observation_state_19`, FLOAT

Vector columns are flattened into scalar FLOAT measurements (single precision). The source index column is retained as sample_index.

Conversion notes

Time = round(timestamp * 1000) with millisecond precision; time restarts inside each episode, while episode_index and task_index identify the TsFile device.
The original timestamp field is omitted because it is exactly represented by Time / 1000.
Camera video streams are NOT included in this repository; they remain in the source videos tree.
meta/ is mirrored from the source. Aside from the redundant timestamp column and the excluded videos, no source rows or numeric fields are dropped.

Read example

from tsfile import TsFileReader

with TsFileReader("data/stack_cubes_flexiv_0801.tsfile") as reader:
    print(reader.get_all_table_schemas()["stack_cubes_flexiv_0801"])
