The workspace of four kinematically different types of Stewart Platforms have been analized. The workspace analysis has been recognized as an important process in designing a robot in the sense that it provides the information about the mechanism dimensions which satisfy the design requirements for the robot. In this paper, the workspace of Stewart Platforms has been analized by developing an algorithm using a search technique for boundary points of the workspace. The inverse kinematics of a Stewart Platform has been used in the development of the algorithm.
The sectional views of the workspaces of four types of Stewart Platforms have been plotted on the planes perpendicular to the base platforms. The effect of mechanism geometry such as the sizes of the platforms, and the leg and joint constraints on the workspaces has been also analized. Through this work, it has been found that the kinematic types of Stewart Platform do not have much influence on the workspace.
