Self-Aligning EPM Connector: A Versatile Solution for Adaptive and Multi-Modal Interfaces (2508.16008v1)

Abstract: This paper presents a multifunctional connector based on electro-permanent magnet (EPM) technology, integrating self-alignment, mechanical coupling, fluid transfer, and data communication within a compact SLA-3D printed structure. Experimental results demonstrate reliable self-alignment, efficient fluid transfer in single-loop and dual-channel modes, and robust data transmission via integrated electronic control. The connector exhibits high flexibility in accommodating axial, angular, and lateral misalignments while maintaining low energy consumption. These features make it highly suitable for modular robotics, electric vehicle charging, household robotic platforms, and aerospace docking applications.
