Some Novel Lower-Mobility Parallel Mechanisms

This paper gives a brief description of some novel lower-mobility parallel mechanisms developed in our recent research, including two 4-DOF (degrees-of-freedom) parallel mechanisms and two 5-DOF parallel mechanisms. The two 4-DOF parallel mechanisms can perform three dimensional rotations and one translation. The two 5-DOF parallel mechanism can perform three dimensional rotations and two translations. All of these novel parallel mechanisms have symmetrical mechanical structures.Copyright © 2002 by ASME
