Cartesian Coordinate Take-out Robots
According to Wikipedia, a cartesian coordinate robot (also called linear robot) is an industrial robot whose three principal axes of control are linear (they move in a straight line rather than rotate) and are at right angles to each other. The three sliding joints correspond to moving the wrist up-down, in-out, back-forth. Among other advantages, this mechanical arrangement simplifies the Robot control arm solution.
A popular application for this type of robot is a computer numerical control machine (CNC machine) and 3D printing. The simplest application is used in milling and drawing machines where a pen or router translates across an x-y plane while a tool is raised and lowered onto a surface to create a precise design. Pick and place machines and plotters are also based on the principal of the Cartesian coordinate robots.
