Its mostly function is used to complete transition and motion of exact apparatuses and objects. Because of its small volume and simple drive principle, it is widely used in the field of electronic and electric industry, home-used electric-ware industry and exact mechanism. The whole system is composed of manipulator hand, manipulator arm, joints and servo motor driving system. By servo motor’s driving of each degree of freedom, it completes location change of manipulator hand and manipulator arm. The idiographic designing content is designing of in-phase tooth-shape strap, designing of silk-bar nut, designing of shell and axis and the choice of servo motors. On the base of checking its structure intensity, while it satisfied, we optimize designing of the structure of SCARA robots. This paper put its emphases on research of its structure designing and kinematics analysis. At the beginning of this paper, it introduces the development and sort of robots. It introduces detailed detail among the processing of the structure designing of a SCARA robot and its kinematics analys
