dagger_final_1_21 (TsFile)

Apache TsFile version of the LeRobot dataset lerobot-data-collection/dagger_final_1_21.

Overview

Bimanual openarms-follower demonstrations (LeRobot v3.0).

Robot: openarms_follower (bimanual)
Episodes: 1
Frames: 841
Sampling rate: 30 fps
Tasks: 1

Schema (TsFile structure)

Time (INT64, milliseconds) — round(timestamp * 1000), restarting per episode.
episode_index / task_index (TAG) — the device dimension. Query a single episode with WHERE episode_index=N.
FIELD — frame_index, sample_index, and the flattened state/action vectors (observation_state_0..15, action_0..15) as single-precision FLOAT.

The robot's the left_wrist / right_wrist / base camera streams are time-series-irrelevant and not uploaded to this repository; get them from the original dataset (its videos/ directory). The source meta/ is mirrored here.

Usage

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