Pick Up the Red Block (TsFile)

Apache TsFile version of k1seul/pick_up_the_red_block. Modalities: Time-series.

Overview

This LeRobot dataset contains Trossen AI Solo demonstrations for the task “Pick up the red block and place it in the bowl.”

Dataset Scale

• 62 episodes, 43,296 frames, one task, sampled at 30 fps.
• The train split contains 43,296 TsFile rows in data/pick_up_the_red_block_train.tsfile.
• The pinned source tree contains 62 per-episode Parquet shards declared by meta/info.json. It also contains data/chunk-000/file-000.parquet, an aggregate copy of episodes 0–9; that redundant 7,422-row copy is not converted a second time.

Conversion details

Time is round(timestamp * 1000) in milliseconds. The source timestamp column is therefore not stored as a separate FIELD; frame_index is retained and source index is named sample_index. Camera videos are not included in this time-series repository and remain in the original dataset.

Schema (TsFile structure)

• Time (INT64, milliseconds) is the per-episode sample time.
• episode_index and task_index are TAG columns identifying the device series.
• frame_index and sample_index are INT64 FIELD columns.
• action_0 through _6 and observation_state_0 through _6 are FLOAT FIELD columns for the seven Trossen AI Solo joints.

For example, select one device with WHERE episode_index='0' AND task_index='0'.

Usage

Read data/pick_up_the_red_block_train.tsfile with the Apache TsFile Java or Python SDK.
