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.
