## Overview
**RoCo Task Board Assembly Demonstrations** is a real-world robot manipulation dataset for assembling parts on a task board. It is released by **Sharpa** in a **LeRobot-compatible** format for imitation learning, visuomotor policy learning, visual-tactile representation learning, and contact-rich manipulation research.
Task-board assembly requires precise part localization, fine contact timing, bimanual coordination, and robust perception under hand-object occlusion. The demonstrations include synchronized multi-view video, tactile observations, proprioceptive state, torque signals, and action targets.

## Example Views
The demonstrations include synchronized head, wrist, and tactile video streams. Each preview below uses a 3-minute window from the same `lerobotv2.1` episode, played at 10x speed. GIF previews render directly in Markdown; click any preview to open the MP4 version. Tactile previews preserve their full wide-frame layout.

## Dataset Statistics
| Item | Value |
| --- | ---: |
| Total collection seasons | 10 |
| `lerobot3.0` seasons | 10 |
| `lerobot3.0` episodes | 151 |
| `lerobot3.0` frames | 733,809 |
| `lerobotv2.1` seasons | 10 |
| `lerobotv2.1` episodes | 151 |
| `lerobotv2.1` frames | 733,809 |
| FPS | 30 |
| Video streams | 6 |
| State/action dimension | 65 |
| Tactile signal dimension | 60 |
| Approximate data size | 104.8 GB |
For new users, we recommend starting from `lerobot3.0`. The `lerobotv2.1` export is included for compatibility with pipelines that still depend on the older LeRobot layout.
## Get Started
### Download The Dataset
Make sure Git LFS is installed before cloning from Hugging Face.
```bash
git lfs install
git clone https://huggingface.co/datasets/SharpaIT/RoCo_TaskBoardAssembly
```
If you want to clone only metadata first and fetch large files later:
```bash
GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/datasets/SharpaIT/RoCo_TaskBoardAssembly
```
If you only want a specific season, use sparse checkout:
```bash
git init RoCo_TaskBoardAssembly
cd RoCo_TaskBoardAssembly
git remote add origin https://huggingface.co/datasets/SharpaIT/RoCo_TaskBoardAssembly
git sparse-checkout init
git sparse-checkout set season_POC22061_2026_06_11_14_29_08_train README.md
git pull origin main
```
### Quick Inspection
Each season contains both `lerobot3.0` and `lerobotv2.1` exports. Inspect `meta/info.json` first to understand the exact schema and file templates.
```python
import json
from pathlib import Path
dataset_root = Path("RoCo_TaskBoardAssembly")
episode_root = dataset_root / "season_POC22061_2026_06_11_14_29_08_train" / "lerobot3.0"
with open(episode_root / "meta" / "info.json", "r") as f:
 info = json.load(f)
print(info["total_episodes"])
print(info["total_frames"])
print(info["features"].keys())
```
## Dataset Structure
The dataset is organized by collection season. Each season contains a `lerobot3.0` export and a `lerobotv2.1` export.

### LeRobot Storage Layout
| Part | Description |
| --- | --- |
| `meta/` | Dataset metadata, feature schema, task metadata, and path templates |
| `data/` | Episode frame data stored as Apache Parquet files |
| `videos/` | Per-camera MP4 videos |
The most important metadata file is `meta/info.json`. It defines `total_episodes`, `total_frames`, `fps`, `splits`, `data_path`, `video_path`, and `features`.
### File Path Templates
LeRobot v3.0 uses templates similar to:
```text
data/chunk-{chunk_index:03d}/file-{file_index:03d}.parquet
videos/{video_key}/chunk-{chunk_index:03d}/file-{file_index:03d}.mp4
```
LeRobot v2.1 uses templates similar to:
```text
data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.parquet
videos/chunk-{episode_chunk:03d}/{video_key}/episode_{episode_index:06d}.mp4
```

### Proprioceptive State
The 65D `observation.state` and `action` vectors are ordered as follows:
| Range | Names | Meaning |
| --- | --- | --- |
| 0 - 6 | `left_arm_j0` to `left_arm_j6` | Left arm joints |
| 7 - 28 | `left_hand_j0` to `left_hand_j21` | Left dexterous hand joints |
| 29 - 35 | `right_arm_j0` to `right_arm_j6` | Right arm joints |

### Video Streams
The complete visual observation set contains six camera streams:
| Feature key | Description | Shape |
| --- | --- | --- |
| `observation.images.head_left` | Left head camera | 480 x 480 x 3 |
| `observation.images.head_right` | Right head camera | 480 x 480 x 3 |

## Usage Recommendations
This release is provided as training data. For local experiments, users may split by season to avoid mixing demonstrations from the same collection session across train and evaluation sets.
For policy learning, a typical setup is:
- Visual observations: one or more `observation.images.*` streams
- Proprioception: `observation.state`
- Optional tactile signal: `observation.tactile`
- Supervision target: `action`
For multi-view policies, start with:
```text
observation.images.head_left
observation.images.head_right
observation.images.wrist_left
observation.images.wrist_right
```
Then add tactile video streams if your model can use high-resolution tactile observations:
```text
observation.images.tactile_deform
observation.images.tactile_raw
```
## Dataset Notes
- This repository contains only the LeRobot exports prepared for release.
- Raw POC recording folders and intermediate HDF5 folders are intentionally excluded from this release.
- The dataset is released by season, not as a single flattened LeRobot root.
- Every released season includes both `lerobot3.0` and `lerobotv2.1`.
- `motor_j0` to `motor_j6` are the torso/motor-related dimensions in `observation.state` and `action`.
- The task is contact-rich and precision-sensitive: policies should expect object contacts, hand-part occlusions, tactile events, and fine pose adjustments.
