## 📖 Overview

The **FastUMI Pro Sample Dataset** provides a public preview of the multimodal sensing capabilities of the FastUMI Pro data collection system.

This release contains **only dozens of sample trajectories** and is intended for:

- System testing  
- Robotics and AI pipeline integration  
- Preliminary algorithm development  
- Demonstrating multimodal alignment and synchronization  


Full-scale datasets are available upon request for research or enterprise collaboration.

## 📊 Data Specifications

**Purpose:** The following table is to provide users with an overview of the technical specifications of the dataset.

| **Data Type** | **Path** | **Shape** | **Type** | **Description** |
|--------------|----------|-----------|----------|-----------------|
| RGB Images | RGB_Images/Frames/*.mp4| (H, W, 3) | uint8 | Multi-view RGB images |
| ToF PointClouds | ToF_PointClouds/PointClouds/*.pcd | variable | pcd | Time-of-Flight point clouds |
| Clamp Data | Clamp_Data/clamp_data_tum.txt | (N, 2) | float | Timestamp + clamp width |
| Merged Trajectory | Merged_Trajectory/merged_trajectory.txt | (N, 8) | float | Fused multi-sensor pose |

---

## 🧭 Data Formats

All pose data (SLAM, Vive, fused) follow the same structure:

```markdown
timestamp  x  y  z  qx  qy  qz  qw

```

| Field | Description | Field | Description |
| :---: | :---: | :---: | :---: |
| timestamp | Unix timestamp | qx | Quaternion X component |
| x | Position X (meters) | qy | Quaternion Y component |
| y | Position Y (meters) | qz | Quaternion Z component |
| z | Position Z (meters) | qw | Quaternion W component |

---

###  Coordinate System 

To ensure correct visualization and control, all pose data adheres to the following right-handed coordinate system (World Frame).
*   **Origin (0,0,0):** Geometric center of the tracking base stations (World Frame).
*   🔴 **X-Axis:** Points Forward (the primary direction of manipulation).
*   🟢 **Y-Axis:** Points Right (relative to the workspace).
*   🔵 **Z-Axis:** Points Upward (opposite to the direction of gravity).

<small><i>Tip: When using simulation environments like ROS or Isaac Gym, ensure your coordinate frame conventions match. You may need to apply a transformation if your framework uses a different "up" axis (e.g., Z-up vs. Y-up).</i></small>

## 📸 How We Collect Data
We collect data using the **FastUMI Pro** hardware suite. This system integrates high-frequency sensors to capture comprehensive multimodal interaction data:

*   **Visual:** Industrial-grade RGB cameras.
*   **Spatial:** Time-of-Flight depth sensors for dense 3D reconstruction.
*   **Haptic/State:** Force-sensitive clamp sensors for precise gripper feedback.
