X-Y stage with rotation and tilt
Abstract:
An X-Y movable stage with rotation and tilt is described. A fixed base comprises a magnetic bed with a checkerboard, hexagonal or pseudo-random pattern of alternating north and south poles on a grid. A movable puck moves, rotates and tilts on the base. The base and puck system is free of any other moving parts. The puck comprises three or more nodes where each node may be energized for a north, south, or off magnetic field, with varying field strength. Embodiments include use in a vacuum or fluid. Light from the base to the puck may be used to charge or power a puck. Methods of mapping node locations, controllers, and applications are described. Embodiments for specific applications are described.
