The principles of FACT have been adapted to help designers synthesize flexures that decouple displacement-based actuators such that they (i) do not impose undesired loads on other actuators, (ii) do not affect the outputs of other actuators, and (Hi) drive the system's stage to move with desired DOFs and minimal parasitic error. Rules have been created for controlling system constraint characteristics (i.e., exact, over, and under-constraint). A FACT-designed flexure system was fabricated and tested to experimentally verify how well its flexures decoupled the outputs of its actuators. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
