电连接器作为在轨服务与维护领域的航天装备基础元件,广泛存在装配和拆卸的接入需求,其自动接入技术涉及接触力感知、视觉识别与定位、机械臂柔顺控制等关键技术,具有重要研究意义和推广价值。本文基于6自由度机械臂、双目结构光相机及其控制软件,构建了不同类型电连接器的自动接入试验平台,采用关键点提取、RANSAC粗配准和ICP精配准等算法,实现了模板点云的精确配准,完成了不同类型电连接器接入状态的高可靠识别;采用机械臂导纳控制,实现了机械臂末端夹具的抓取定位-对中旋拧-插拔拆卸等系列化操控。以Y27和J30等不同类型电连接器作为典型案例进行自动接入作业测试,验证了平台系统和已采用方法的可行性。

Electrical connectors, as the basic components of space equipment for in-orbit servicing and maintenance, have extensive assembly and disassembly access requirements. The automatic access technology involves key technologies such as force sensing, visual recognition and positioning, and compliance control of manipulators. It has important research significance and promotion value. Based on a 6-DOF manipulator, a binocular structured-light camera, and its control software, a test platform for automatic access of different types of electrical connectors was constructed. The template point cloud was precisely aligned using key-point extraction, RANSAC course registration, and ICP fine registration algorithms. The high-reliability identification of different types of electrical connectors in the access state was completed. The impedance control of robotic arm was used to achieve a series of manipulations, including grasping and positioning, aligning, screwing, plugging and disassembly. The feasibility of the platform system and method was verified by testing the automatic access operation of Y27 and J30 electrical connectors as typical cases.
