This study developed a laparoscopic robotic digital twin system using parametric modeling (SolidWorks) and kinematic mirroring. Core components include instruments, endoscope, and robotic arms. Optimized 3D models were integrated into Unity (FBX/HingeJoint/C#) with virtual endoscopic alignment via Zhang’s calibration (intrinsic/extrinsic matrices), ensuring virtual-physical geometric consistency.
