Abstract:
A micro-electro mechanical multiple degree of freedom platform assembly formed from a plurality of thin films on a substrate, comprising:a moveable planar platform having three connection points, said connection points defining a platform triangle, said platform being capable of being moved away from the plane of said substrate; three fixed-length linkages capable of being moved away from the plane of said substrate, each linkage having one end pivotally connected to one of said platform connection points through a platform joint, each connection point being connected to only one linkage; and each linkage having an opposed end pivotally connected to said substrate; at least one linear drive, each drive including a traveling member capable of controlled movement along a linear path adjacent said substrate; and each traveling member being pivotally connected to an opposed end of one of said linkages through a base joint, each linkage being connected to only one traveling member; wherein when each of said opposed ends are in a predetermined position, said linkages and said platform are coplanar to and adjacent to said substrate, and when any of said traveling members is in any other position along said linear path, at least the linkage connected to that member and said platform is neither coplanar to nor adjacent to said substrate.
