ABSTRACT:
This invention relates to parallel mechanisms and, to be more specific, mechanical devices consisting of plates connected together by several legs. The 6 degrees of freedom variable leverage motion simulator, shown in FIG. 1, basically an in-parallel actuated robotic platform with three serial subchains, features a novel design that can provide 6 degrees of freedom motion capability. Two simplified versions, shown in FIG. 3 and FIG. 5, can provide selective 3 degrees of freedom motion. The designs also exploit the use of various pickup points which make them very easy to adapt to different actuators and to provide different leverages. Potential energy storage devices can be installed to the pickup points as a safety feature and to reduce the payload of actuators. The preferred embodiments of this invention may be used, among other things, as a motion/force simulator for flight simulation, driving simulation or object interaction and telepresence issues in virtual reality environments.
