|
| ## 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. |
|
|
| This dataset supports the [RoCo IROS 2026 Challenge](https://rocochallenge.github.io/RoCo-IROS2026/). Teams can use it to develop, train, and evaluate policies for the task-board assembly track. Interested participants should visit the official competition website and complete the [registration form](https://forms.gle/d2NKNAE7dqSfYZB87) to receive challenge updates and participation details. |

|
|
| ## 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 |
| ``` |
|
|
| ## Features Schema |
|
|
| ### Main Feature Groups |
|
|
| | Feature | Type | Shape | Description | |
| | --- | --- | ---: | --- | |
| | `observation.state` | float32 | 65 | Joint-space robot state | |
| | `action` | float32 | 65 | Joint-space action | |
| | `observation.state.joint_torque` | float32 | 65 | Joint torque signal | |
| | `observation.tactile` | float32 | 60 | Tactile force/torque signal | |
| | `observation.images.*` | video | varies | Multi-view visual observations | |
| | `timestamp` | float32 | 1 | Timestamp | |
| | `frame_index` | int64 | 1 | Frame index within an episode | |
| | `episode_index` | int64 | 1 | Episode index | |
| | `task_index` | int64 | 1 | Task index | |
|
|
| ### 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 | |
| | 36 - 57 | `right_hand_j0` to `right_hand_j21` | Right dexterous hand joints | |
| | 58 - 64 | `motor_j0` to `motor_j6` | Torso / motor-related 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 | |
| | `observation.images.wrist_left` | Left wrist camera | 480 x 480 x 3 | |
| | `observation.images.wrist_right` | Right wrist camera | 480 x 480 x 3 | |
| | `observation.images.tactile_deform` | Tactile deformation video | 480 x 1200 x 3 | |
| | `observation.images.tactile_raw` | Raw tactile video | 480 x 1600 x 3 | |
|
|
| Video files are MP4 without audio. Codec may differ across exports and seasons. `lerobot3.0` is primarily AV1, while `lerobotv2.1` is primarily H.264. |
|
|
| ## Tactile Modality |
|
|
| The dataset includes tactile observations as both compact numeric signals and high-resolution video streams. These modalities are synchronized with the robot state, action, and visual camera streams at 30 FPS, making them suitable for contact-rich policy learning and visual-tactile representation learning. |
|
|
| | Tactile feature | Type | Shape | Description | |
| | --- | --- | --- | --- | |
| | `observation.tactile` | float32 | 60 | Per-frame tactile force/torque signal: 10 fingertips x 6 axes | |
| | `observation.images.tactile_deform` | video | 480 x 1200 x 3 | Deformation-oriented tactile video stream that visualizes contact-induced surface changes | |
| | `observation.images.tactile_raw` | video | 480 x 1600 x 3 | Raw tactile camera stream preserving the full tactile sensor image layout | |
|
|
| The `observation.tactile` vector provides a compact force/torque representation for each frame. It contains 10 fingertip groups: left and right `thumb`, `index`, `middle`, `ring`, and `little`. Each fingertip contributes six values, ordered as `fx`, `fy`, `fz`, `tx`, `ty`, and `tz`, for a total of 60 dimensions. |
|
|
| The two tactile video streams provide complementary image-based tactile observations: `tactile_deform` emphasizes deformation patterns caused by contact, while `tactile_raw` preserves the raw tactile image for users who want to build their own visual-tactile preprocessing or representation learning pipeline. For downstream experiments, users can start with `observation.tactile` as a lightweight contact signal, then add one or both tactile video streams when the model architecture can handle the additional spatial resolution and bandwidth. |

|
| ## 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. |
