======A reinforcement learning approach to robotic suturing======

**Last updated: 2/20/2022**


======Summary======

{{:courses:456:2023:projects:456-2023-20:ezgif.com-video-to-gif_1_.gif?400|}}

Our goal is to develop an OpenAI Gym compatible interface for the Surgical Robotics Challenge (SRC) environment with efficient, accurate reinforcement learning (RL) algorithms. Currently, no robust framework exists for RL tasks in surgical robotics environments. We propose an OpenAI Gym environment based on a autonomous robotic suturing environment with benchmark algorithms to pave the way for future surgical automation.

======Background, Specific Aims, and Significance======
Current RL techniques have seen significant progress in the robotics domain; mostly due to open-source RL frameworks and an emerging corpus of environments to train autonomous robotic simulations, such as OpenAI Gym. However, there exist a lack of platforms which offer environments conducive to medical robotics. 

The Surgical Robotics Challenge (SRC) is a simulation platform to develop algorithms to address various questions in surgical robotics automation  with:
  * Two 7-DOF instrument arms based on the da Vinci Surgical System large needle driver
  * Controllable camera based on the da Vinci Endoscopic Camera Manipulator
  * Suturing phantom
  * Needle with a suture
Specifically, the 2021-2022 SRC consists of three challenges:
  - Challenge 1: Find the needle
  - Challenge 2: Grasp needle and drive through tissue
  - Challenge 3: Suture the phantom

Our aim is to make the SRC environment compatible with the OpenAI Gym API for RL research and provide benchmark RL algorithms for the 2021-2022 SRC challenge tasks. Generally, we seek to create an OpenAI Gym environment with different rewards for each task (e.g. grasping a needle, inserting the needle, and guiding the needle to the target exit hole) and use state-of-the-art (SOTA) RL methods to learn the policy as a benchmark for future surgical automation research. Having an open-source environment on OpenAI Gym will produce wide applicability and drive more innovation and attention in autonomous surgical robotics systems.
======Deliverables======
 
  * **Minimum: Open-source OpenAI Gym environment to train RL algorithms** (Expected by 4/12/2023)
    - Transfer of robotics surgical challenge to OpenAI Gym environment (sandbox env)
    - Core functionality for OpenAI Gym: `make()`, `reset()`, `step()`, `render()`
    - Environments built to accomplish SRC Challenge #2: grasp needle and drive through tissue
    - Documentation of our work through entire development pipeline
    - Compatibility with dVRK tools in the LCSR lab

  * **Expected: Benchmarked performances of the SOTA RL algorithms** (Expected by 4/28/2023)
    - Literature review of SOTA RL Algorithms 
    - RL algorithm training for automated suturing task (SRC #2)
    - Performance evaluation (accuracy and efficiency) of RL algorithms & 2021-2022 SRC winners


  * **Maximum: Submission as NeurIPS (Datasets and Benchmark track), additional SRC tasks** (Expected beginning of June)
    - Paper for NeurIPS conference (database and benchmarking track): 6/1/23 for abstract, 6/7 for full paper



======Technical Approach======
Our goal is to develop an OpenAI gym environment to automate the suturing process with reinforcement learning. Developing the environment and RL algorithm in accordance with guidelines of Surgical Robotics Challenge #2 (grasping and driving the needle), we will ensure compatibility with the AMBF-RL toolkit environment. Ultimately, we hope to submit a paper to the NeurIPS conference in June 2023.

To address the suturing task, we will develop an environment with three sub-tasks: grasp, insert, and target. Given the robotic arm location and needle location, the `grasp` task will navigate the robotic arm towards the needle at an ideal angle and pick up the needle. The `insert` task will handle the needle positioning and puncturing through the starting point of the tissue, and the `target` task will guide the needle through the tissue and pull the needle out of the tissue.
