“…But they can be confined by the precision design method. For modeling and analysis for the position and orientation errors of the parallel robot, many studies have been performed [2][3][4][5][6][7]. Some researches use the modulus analysis and distance error modeling analysis, which is suitable for parallel robot with defined axis and lack of universal applications.…”

The precision analysis of a 3-PRS parallel robot with three DOFs has been studied in this paper. The 3-PRS parallel robot has been introduced with its kinematics analysis. The closed-loop vector model has been introduced. By the differential method, the mathematic error model of the position and orientation has been built. The forward error solution has been deduced including all the structural errors. Given the structural errors, the output errors of the parallel robot can be solved by the introduced model. The effect of the variation of the position and orientation of the 3-PRS on the output errors of the parallel robot have been analyzed

Motion accuracy is one of the key point for parallel robots. In the paper, error modeling and motion error analysis of a 3-DOF parallel robot 3-PRS has been studied in this paper. First, the 3-PRS parallel robot and its kinematics has been introduced with its kinematics analysis. Based on the reverse kinematics analysis of 3-PRS, the motion error has been modeled. Then, motion error analysis has been performed for 3-PRS. The analysis results show the clear tendency of structural error effects on the motion errors.
