A kind of redundant actuation parallel mechanism with eight sub-chains is proposed and analyzed in this article. Output kinematic characteristics of the moving platform are analyzed by degree-of-freedom method and redundant degree-of-freedom number is analyzed. The moving platform of this redundant parallel mechanism can fulfill a six degree-of-freedom motion while the number of needed input variables...
Type synthesis of robot mechanism is an important and complicated research field. There are many type synthesis methods at present and different method is fit for different type of robot mechanism. This paper studies all kind of the degree of freedoms (DOF) for robot mechanism. Three DOFs including I-DOF, M-DOF and E-DOF are summarized and used to appraise characteristics and type for a given robot...
Virtual reality technology utilizes computer to construct three dimensional dummy environment and users can act with it by the aid of special computer input/output devices. This paper introduces a novel computer input device based on the parallel mechanism technology. This computer input device provides six degree of freedoms (DoF) operation ability, as is more flexible than the conventional two dimensional...
