3-PRS parallel robot for battery swapping of electric vehicle

The application of parallel mechanism (PM) is getting more and more widely due to its many advantages. In this field, the research of the 3-PRS parallel mechanism, which undergo one translational degree of freedom (DOF) and two rotation DOFs, has a high practical value and great significance, but far from reaching its proper degree in practical applications at present. This paper presents a new application of 3-PRS PM and provides the whole process of its analysis of inverse kinematics and parasitic motion.
