A '''cartesian coordinate robot''' (also called '''linear robot''') is an [[industrial robot]] whose three [[principal axis (mechanics)|principal axes]] of control are linear (i.e. they move in a straight line rather than rotate) and are at [[right angle]]s to each other.The three sliding joints correspondscorrespond to moving the wrist up-down,in-out,back-forth. Among other advantages, this mechanical arrangement simplifies the [[Robot control]] [[arm solution]]. [[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.

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. [[Automated storage and retrieval system|Pick and place]] machines and [[plotter]]s are also based on the principal of the '''cartesian coordinate robot'''.
