The authors are working closely the development of the prototype a unique serial kinematic structure of modular configuration. The prototype is developed in accordance with innovative ideas to develop a rotary linkage unlimited angle of rotation as the basic structural unit for such a kinematic motion structure. After verification of the prototype would be a proprietary idea of Universal Rotary Model (URM) to exercise in robotics as a basic building block movement of the robot or manipulator used mainly in industry eventually in the manufacturing technology utilizing unique and specific options suggested solutions. The article deals with the specifics of production documentation, available to select the optimum components, modifications and the effects of partial solutions, which together form a harmonious functional but extensible and modifiable whole.
