This invention is a compact motion simulator incorporating a potential energy assisted drive mechanism and a direct memory motion method. The mechanism provides movement of heavy loads with reduced power compared to simulators of its type employing direct drive mechanisms. Potential energy devices are connected to rigid leverage members extending from the rotational axes. When moved about said axes, by means of powered actuators, displacement of the load away from center causes the potential energy devices to expand and store energy. This energy acts on opposition to the forces that created it producing a state at or near static equillibrium and thus greatly reduces power required to move the load back to center. The direct memory motion method uses a software component memory reader that gains access to the running process of a simulation program and derives motion data from memory addresses used by the programs graphical and physics engines.
