=== Construction ===

Each axis of a Cartesian coordinate robot typically is a [[linear stage]] consisting of a linear [[actuator]] geometrically parallel with [[Linear-motion bearing|linear bearings]]. The linear actuator is typically between two linear bearings spaced apart from each other to support [[Moment (physics)|moment]] loads.  Two perpendicular linear stages stacked on top of each other form ana [[X-Y table|XY table]].  Examples of XY tables include the XY axes of [[Milling (machining)|milling machines]] or precision positioning stages. At least one of the linear stages of [[cantilever]]ed Cartesian coordinate robots is supported at only one end. Cantilevered construction provides accessibility to parts for pick-and-place applications such as [[laboratory automation]] for example. Cartesian coordinate robots with the horizontal member supported at both ends are sometimes called gantry robots; mechanically, they resemble [[gantry crane]]s, although the latter are not generally robots. Gantry robots are often quite large and may support heavy loads.
