Research on the Advantages of Nonlinear Algorithm for Magnetic Positioning of Capsule Robot

This paper studies the nonlinear positioning technology of the capsule robot in the magnetic field, aiming to prove that the nonlinear algorithm has higher calculation accuracy than the traditional algorithm. Given the complex and unpredictable characteristics of the human body environment, magnetic positioning technology is crucial for the positioning of capsule robots in the internal human body environment. Therefore, improving the accuracy and reliability of positioning is of great significance for medical applications and diagnostic processes. In this study, the Maxwell simulation model of the magnet was first established to simulate the behavior of the magnet in the magnetic field, and the magnetic field distribution of the permanent magnet was analyzed. On this basis, we compare the proposed nonlinear algorithm with traditional algorithms. By comparing the experimental results and calculating the accuracy evaluation, we found that the nonlinear algorithm exhibited higher accuracy and stability in the magnetic positioning of the capsule robot than the traditional algorithm. This research provides a new method and technical support for the precise positioning of capsule robots, which will help improve the accuracy and feasibility of endoscopic surgery and diagnosis.
