# Dynamic Tossing

## Visualizers

## 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: `umi-dynamic-tossing`
- Project: `UMI (Core)`
- Task: `Dynamic Tossing`
- Upstream download/source URL: https://real.stanford.edu/umi/data/dynamic_tossing/dynamic_tossing.zarr.zip
- Upstream project page: https://umi-data.github.io
- Contact: [e-mail]
- Original paper: Chi et al. 2024
- Notes: 284 demos; 1 env; image+proprio

## Dataset Format
- Storage format: LeRobot v3 parquet-based dataset
- Total episodes: 284
- Total frames: 368428
- 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.
