Claim Text:
1. A linear-motion stage comprising: a base; a first multiple-arm linkage extending from the base to a first carriage attachment piece; a second multiple-arm linkage extending from the first carriage attachment piece to the base; wherein: the first multiple-arm linkage constrains a motion of the first carriage attachment piece to motion in a first plane and the second multiple-arm linkage constrains the first carriage attachment piece to motion in a second plane, the first and second planes intersecting at a plane intersection line; the first and second multiple-arm linkages constrain the motion of the first carriage attachment piece along a carriage motion line, the carriage motion line being parallel to the plane intersection line; and the first and second multiple-arm linkages are arranged angularly asymmetric with respect to a plane transverse to the plane intersection line.
