# Pick Brocolli

## Visualizers
- [LeRobot Visualizer](https://huggingface.co/spaces/lerobot/visualize_dataset?path=%2FDaivdYuan%2Fexumi-pick-brocolli-lerobot)
- [Neural Motion Visualizer](https://platform.neural-motion.org/open?repo=DaivdYuan%2Fexumi-pick-brocolli-lerobot)


## Overview
This dataset is a conversion from an upstream robotics dataset into **LeRobot v3-compatible format**.
It is intended to provide reproducible access in a unified schema.

## Source Dataset
- Dataset ID: `exumi-pick-brocolli`
- Project: `exUMI`
- Task: `Pick Brocolli`
- Upstream download/source URL: https://huggingface.co/datasets/silicx/exUMI/resolve/main/pick_brocolli.zarr.zip?download=true
- Upstream project page: https://silicx.github.io/exUMI/
- Contact: silicxuyue@outlook.com
- Original paper: Xu et al. 2025
- Notes: 170 demos; image+tactile

## Dataset Format
- Storage format: LeRobot v3 parquet-based dataset
- Total episodes: 30
- Total frames: 13137
- FPS: 30
- Robot type: generic_robot
- Observation feature: `observation.state` with shape `[7]`
- Action feature: `action` with shape `[7]`
- Video streams: present

## Video Modalities
- `observation.images.camera0_rgb`: shape `[224, 224, 3]`
- Frame rate: `30` FPS

## Conversion Notes
- Target schema: LeRobot v3
- Conversion path: ingest -> preprocess -> zarr probe -> convert 1 episode -> upload
- `action` fallback may be used when upstream `data/action` is missing.
