摘要
High-success-rate robotic assembly of industrial components requires stable perception, accurate pose estimation, and smooth motion execution under complex operating conditions. However, conventional vision-guided systems are often affected by illumination variations and depth noise, resulting in unstable localization. Furthermore, traditional motion planning often overlooks kinematic constraints, causing abrupt dynamic disturbances. This paper presents an integrated perception-reasoning-planning framework to improve the performance of vision-guided robotic assembly and increase its success rate. In the perception stage, an Interacting Multiple Model Kalman Filter (IMM-KF) adaptively fuses visual observations across different motion states to improve the temporal consistency of three-dimensional localization. For axisymmetric components, a geometry-aware reasoning method is established by combining point cloud preprocessing, Random Sample Consensus (RANSAC)-based end-face extraction, and Principal Component Analysis (PCA)-based normal estimation, enabling geometry-based 6-DoF pose estimation without deep regression training. Finally, a hierarchical motion planning strategy is incorporated, utilizing manipulability-based singularity avoidance and second-order continuous (C²) trajectory generation to improve motion execution stability. Experimental results on a collaborative robotic platform performing shaft-hole assembly under varying component placement angles and positions validate that the proposed framework enhances spatial localization consistency and significantly increases the assembly success rate from 32% to 89% under practical assembly uncertainties.
