Stiffness and Vibration Resistance Analysis of Isotropic Stewart Platform (ISP) and Common Stewart Platform (CSP)

Parallel manipulators found wide applications in the industry such as entertainment, heavy, and aerospace industries. However, the contemporary growth of the economy and industry demands additional and exceptional capabilities for robots. Parallel manipulator applications in the industry are pretty specific and complex rather than serial manipulators. Therefore in this research, we proposed an isotropic Stewart parallel manipulator to enhance robot stiffness and payload capacity capabilities. Moreover, proves the concept by experimental methods. The main contribution of this paper is to rely on robot design, joint positions, and comparison of experimental results to prove the concept idea. The research paper is organized in the following order: introduction, design concept, joint positions and simulation, experimental results, and conclusion.
