Simulation Analysis of Deformation Control for Magnetic Soft Medical Robots

摘要

Dear Editor, This letter presents a biocompatible cross-shaped magnetic soft robot and investigates its deformation mode control strategy through COMSOL modeling and simulation. Magnetic soft robots offer novel avenues for precise treatment within intricate regions of the human body. However, the biosafety and precise control characteristics of robots need to be further improved for practical medical use. In this study, a cross-shaped magnetic soft robot was designed based on bio-compatible chitosan material. The cross-shaped magnetic soft robot exhibited programmable and controllable deformation behaviors by manipulating the external magnetic field and the composition of magnetic materials through the finite element method. The findings of this study provide support for the precise control of magnetic soft medical robots and offer insights for the design of programmable motion robots.
