→Applications: Separated the two paragraphs to distinguish between the two applications: 1) CNC machines and 2) pick and place machines. Reworded the second paragraph since it was copied word-for-word from the website, https://robot.cfp.co.ir/en/robots/cartesian-gantry. However this website has some nice videos of cartesian coordinate robots, so I added a link to it.
A C'''cartesianartesian 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.<ref>{{Cite book|title=Mechatronics and Robotics Engineering for Advanced and Intelligent Manufacturing|last=Zhang|first=Dan|last2=Wei|first2=Bin|date=2016|publisher=Springer|year=|isbn=978-3-319-33580-3|___location=Cham|pages=31}}</ref> 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]]. It has high reliability and precision when operating in three-dimensional space.<ref>{{Cite book|title=Advanced High Strength Steel And Press Hardening - Proceedings Of The 4th International Conference On Advanced High Strength Steel And Press Hardening (Ichsu2018)|last=Mingtu|first=Ma|last2=Yisheng|first2=Zhang|date=2018|publisher=World Scientific|year=|isbn=978-981-327-797-7|___location=Singapore|pages=526}}</ref> As a robot coordinate system, it is also effective for horizontal travel and for stacking bins.<ref>{{Cite book|title=Fundamentals of Robotics Engineering|last=Poole|first=Harry H.|date=2012|publisher=Van Nostrand Reinhold|year=|isbn=978-94-011-7052-9|___location=New York|pages=35}}</ref>
[[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.
Line 11:
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 machines and [[plotter]]s where a tool such as a router or pen translates across an ''x-y'' plane and is raised and lowered onto a surface to create a precise design.
[[Automated storage and retrieval system|Pick and place]] machines are another application for cartesianCartesian coordinate robots. For example, overhead gantry Cartesian robots are [https://robot.cfp.co.ir/en/robots/cartesian-gantry applied] for continuous parts loading and unloading on [[CNC]] lathes production lines, performing 3-axis ''(x, y, z)'' pick and place operations of heavy loads with high speed performance and high positioning accuracy. In general, overhead gantry Cartesian robots are suitable for many [[automation]] systems.<ref>{{cite web|title=When do you need a gantry robot|url=http://www.linearmotiontips.com/when-do-you-need-a-gantry-robot/|website=Linear Motion Tips|publisher=Danielle Collins|accessdate=21 September 2017}}</ref>
