Novel Robotic Manipulator With Four Screws for Automated Storage and Retrieval System

A novel 4-screw robotic manipulator (FSR manipulator) used in automated storage and retrieval system (AS/RS) is designed. Microplates, which have a projection, are mounted on the four screws. Mathematical modeling, force analysis, static analysis and simulations are conducted. Compared with the existing robot hands, the FSR manipulator is simpler in mechanical structure and control system.
