Motion Control of a Video Capsule for Gastrointestinal Navigation

MSc assignment

Project Description:

The development of controllable video capsule endoscopy (VCE) is a critical step toward improving gastrointestinal (GI) diagnostics. Traditional video capsules rely on passive peristaltic motion, which limits their ability to navigate precisely and capture targeted imaging. This MSc project will focus on designing and implementing a motion control system for a magnetically actuated video capsule, enabling real-time, guided navigation inside the GI tract. The project will explore magnetic control strategies, integrating permanent magnet-based robotic actuation and electromagnetic control to enable precise orientation and position control. The final goal is to optimize the capsule’s movement for better imaging coverage and improved diagnostic capabilities.

Research Objectives 

  1. Develop a Control Algorithm for Magnetic Actuation:

    • Design a robust control system that allows real-time, adjustable motion of the capsule.
    • Optimize motion parameters to ensure smooth movement while avoiding excessive rotational drift.
  2. Enhance Navigation Stability and Positioning Accuracy:

    • Investigate feedback-based control strategies using real-time position tracking (e.g., X-ray or external sensors).
  3. Improve Imaging Efficiency through Controlled Motion:

    • Develop motion planning techniques to maximize imaging coverage and stability.
    • Prevent uncontrolled capsule tumbling, ensuring optimal camera focus.
  4. Validate the Motion Control System in a Simulated GI Environment:

    • Conduct ex vivo experiments using porcine intestines to assess real-world feasibility.
    • Analyze system performance based on navigation accuracy, imaging quality, and response time.
