A Novel 5-DOF welding robot based on SCARA

摘要

This paper raises and analyses a novel 5-DOF welding robot which is based on SCARA. The robot is not only compatible but multifunctional because of the introduction of functional end that consists of two degrees of freedom, which are mutually perpendicular. After building the model, the kinematics analysis is carried out, through which the general formula of the forward as well as inverse kinematics is reached with D-H method. And only in that way, the human can get the method which is used for the position and velocity of the 5-DOF robot. In order to ensure the reliability of the robot in practical application, the modality of it is analyzed with ANSYS.
