# Anubis Stack Tuna EEF Pose 50 Fixed (TsFile)

Apache TsFile version of [`euijinrnd/anubis_stack_tuna_eefpose_50_fixed`](https://huggingface.co/datasets/euijinrnd/anubis_stack_tuna_eefpose_50_fixed). Modalities: Time-series.

## Overview

This LeRobot dataset contains 50 demonstrations for the task “Restock the tuna can,” including state, action, and quaternion action signals.

## Dataset Scale

- 50 episodes, 11,830 frames, one task, sampled at 50 fps.
- The `train` split contains 11,830 TsFile rows in `data/anubis_stack_tuna_eefpose_50_fixed_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](https://huggingface.co/datasets/euijinrnd/anubis_stack_tuna_eefpose_50_fixed/tree/main/videos).

## 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 `_19`, `action_0` through `_22`, and `action_quat_0` through `_18` are FLOAT FIELD columns.

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

## Usage

Read `data/anubis_stack_tuna_eefpose_50_fixed_train.tsfile` with the Apache TsFile Java or Python SDK.
