Abstract:
A Cartesian robot, comprising:a base member having a planar y-reference surface extending in a plane along a length of said base member; a transverse member moveably mounted to said y-reference surface to move along an x-axis parallel to the plane thereof, said transverse member comprising a reference slab supported by at least one support member, wherein said reference slab has a length transverse to the x-axis; a planar z-reference surface extending in a plane along the length of said reference slab; and a y-carriage moveably mounted to said z-reference surface to move along an axis parallel to the plane of said z-reference surface and inclined at a constant angle with respect to a y-axis; wherein a z-position of said y-carriage along a z-axis is determined by a corresponding position of said y-carriage along said z-reference surface and a rigid body tilt of said reference slab, and wherein the x, y, and z-axes define a Cartesian coordinate system.
