OMX-F 0702CR (TsFile)

Apache TsFile version of dream-79/omx_f_0702CR. Modalities: Time-series.

Overview

This LeRobot dataset contains OMX-F demonstrations for picking up the fixed blue block and placing it in the yellow basket.

Dataset Scale

• 39 episodes, 19,605 frames, one task, sampled at 30 fps.
• The train split contains 19,605 TsFile rows in data/omx_f_0702cr_train.tsfile.

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.
• observation_state_0 through _5 and action_0 through _5 are FLOAT FIELD columns for the six OMX-F joints.

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

Usage

Read data/omx_f_0702cr_train.tsfile with the Apache TsFile Java or Python SDK.
