# SutureBot: A Precision Framework and Benchmark for Autonomous End-to-End Suturing
This dataset is part of the **SutureBot** project, a benchmark for developing and evaluating autonomous surgical robotic policies for end-to-end suturing. It contains high-resolution, multi-camera video and robot kinematics from real robot demonstrations on tissue phantoms, supporting research in imitation learning, vision-language-action modeling, and surgical autonomy.
[project website](https://suturebot.github.io/) | [code repository](https://github.com/SutureBot/SutureBot/tree/ACT).
## Dataset Summary
The dataset includes:
- **Stereo endoscope images** (`left_img_dir`, `right_img_dir`)
- **Wrist camera views** (`endo_psm1`, `endo_psm2`)
- **Low-level kinematics** (end-effector pose, joint angles, jaw state, etc.) in `ee_csv.csv`
- **Multiple tissues** and **multiple task types** (e.g., needle pick-up, suturing)
- All data is organized by:
tissue_[id]/[task_name]/[episode_timestamp]/
The following is a visualization of the dataset folder structure:

Each episode is a complete trajectory from a real robotic execution using a da Vinci Research Kit (dVRK) platform.

## Usage
This dataset is designed for training and evaluating autonomous policies that take as input multi-view RGB images (optionally language-conditioned), and output continuous control actions.
It supports a wide range of applications including:
- Behavioral cloning and offline RL
- Multi-modal policy learning (images + kinematics + language)
- Visual servoing and tool tracking
- Surgical robot benchmarking
---
## File Structure
Each episode contains:
- `left_img_dir/`: Left endoscope camera images
- `right_img_dir/`: Right endoscope camera images
- `endo_psm1/`: Right wrist (PSM1) camera images
- `endo_psm2/`: Left wrist (PSM2) camera images
- `ee_csv.csv`: Kinematic data including joint states, poses, and jaw angles
---
## Format
- Image format: `.jpg`, RGB
- Kinematics: CSV with columns such as:
- `timestamp`
- `psm1_pose.position.{x,y,z}`
- `psm1_pose.orientation.{x,y,z,w}`
- `psm1_js[0-5]`, `psm2_js[0-5]`, etc.
- `ecm_pose.*`, `suj_pose.*`, etc.
A complete list of columns is available in the `dataset.croissant.json` schema.
