This study presents the design and simulation of a four‐legged mobile robot engineered for autonomous navigation on the exterior surface of a spacecraft hull. Unlike existing space robotic systems that rely on fixed infrastructure or operate in structured environments, this quadruped robot is designed to traverse complex, nonplanar hull geometries without external support. The robot integrates global path planning using Dijkstra’s algorithm with real‐time orientation correction via an onboard MPU‐6050 IMU, enablin…
