# 📦 FreeTacman
## Robot-free Visuo-Tactile Data Collection System for Contact-rich Manipulation


## 🎯 Overview

This dataset supports the paper **[FreeTacman: Robot-free Visuo-Tactile Data Collection System for Contact-rich Manipulation](http://arxiv.org/abs/2506.01941)**. It contains a large-scale, high-precision visuo-tactile manipulation dataset with over 3000k visuo-tactile image pairs, more than 10k trajectories across 50 tasks.

## 🔬 Potential Applications
The FreeTacman dataset enables diverse research directions in visuo-tactile learning and manipulation:

- **System Reproduction**: For researchers interested in hardware implementation, you can reproduce FreeTacMan from scratch using our 🛠️ [Hardware Guide](https://docs.google.com/document/d/1Hhi2stn_goXUHdYi7461w10AJbzQDC0fdYaSxMdMVXM/edit?addon_store&tab=t.0#heading=h.rl14j3i7oz0t) and 💻 [Code](https://github.com/OpenDriveLab/FreeTacMan).

- **Multimodal Imitation Learning**: Transfer to other LED-based tactile sensors (such as GelSight) for developing robust multimodal imitation learning frameworks.

- **Tactile-aware Grasping**: Utilize the dataset for pre-training tactile representation models and developing tactile-aware reasoning systems.

- **Simulation-to-Real Transfer**: Leverage the dynamic tactile interaction sequences to enhance tactile simulation fidelity, significantly reducing the sim2real gap.

## 📂 Dataset Structure

The dataset is organized into 50 task categories, each containing:
- **Video files**: Synchronized video recordings from the wrist-mounted and visuo-tactile cameras for each demonstration
- **Trajectory files**: Detailed tracking data for tool center point pose and gripper distance


## 🧾 Data Format

### Video Files

- **Format**: MP4
- **Views**: Wrist-mounted camera and visuo-tactile camera perspectives per demonstration

### Trajectory Files

Each trajectory file contains the following data columns:

#### Timestamp
- `timestamp` - Unix Timestamp

#### Tool Center Point (TCP) Data

- `TCP_pos_x`, `TCP_pos_y`, `TCP_pos_z` - TCP position
- `TCP_euler_x`, `TCP_euler_y`, `TCP_euler_z` - TCP orientation (euler angles)
- `quat_w`, `quat_x`, `quat_y`, `quat_z` - TCP orientation (quaternion representation)

#### Gripper Data
- `gripper_distance` - Gripper opening distance
