Patent attributes
A precision tripod motion system is provided. The tripod motion system in one example includes a bottom plate including three spaced-apart bottom single-degree-of-freedom (SDOF) hinge portions, a top plate including three spaced-apart top three-degrees-of-freedom (TDOF) joint portions, with the top plate configured to receive a workpiece, three linear actuators pivotally coupled to the three bottom SDOF hinge portions of the bottom plate and coupled to the three top TDOF joint portions of the top plate, with each linear actuator of the three linear actuators configured to change length over a linear actuation span, and a rotator component and/or a positioning table affixed to the top plate and the bottom plate. The tripod motion system is additionally coupled to a rotator component and a positioning table to provide six degrees of freedom of motion.
