Cartesian robot or linear robot can be collectively refered to as industrial robot, in which three control axes (XYZ axis) move along a straight line instead of rotating. At the same time, their control axes (XYZ axis) are at an angle of 90° to each other and the three sliding joints linear movement back and forth. Therefore, cartesian robots are sometimes called linear robots.

Linear robot
Because the three sliding joints of Cartesian robot can move up and down, left and right, back and forth linearly, it is called linear robot. Cartesian robot control arm solutions are commonly used in CNC machining, 3D printing, milling machines and plotters. The picking and placing machine can also run on a linear Cartesian coordinate robot. One kind of Cartesian robot is that both ends of the dragon are supported horizontally.

Gantry robot
Gantry robot, or Gantry System is one of the Cartesian robots. It needs to be supported at both ends in the horizontal direction in the use function, so it has a shape of a gantry, so it is called a gantry robot. The gantry supported at both ends.

Cartesian robot
Cartesian coordinates is a general term for rectangular coordinate system and oblique coordinate system. Two number axes intersecting at the origin form a plane radial coordinate system. lf the units of measurement on the two number axes are equal, it is called a Cartesian coordinate system. A Cartesian coordinate system in which two number axes are perpendicular to each other is called a Cartesian rectangular coordinate system, otherwise it is called a Cartesian obligue coordinate system.

Cartesian robot refers to Cartesian coordinate robot or XY Cartesian Gantry Robots

Cartesian coordinate robot is a multi-purpose manipulator that can realize automatic control, reprogramming and build spatial Cartesian relations with degrees of freedom. Also known as large Cartesian coordinate robot, multi degrees of freedom and build spatial Cartesian relations with degrees of freedom. lt is also called large rectangular coordinate robot. also known as expert robot or gantry robot. Its working behavior is mainly through completing the linear motion along the X, y and Z axes.

Truss robot
Truss robot is a kind of full-automatic industial eouoment based on the right angle  X, Y and Z coordinate system, which can adjust the wok posion of the workpiece or realize the trajectory mowement of the workpiece. In fact, the name of truss robot is gantry robot, because gantry is often called gantry, and gantry can also be called truss, so there is the saying of truss robot.
To sum up, the working principles of truss robot, gantry robot and linear robot are the same. They are all a kind of cartesian robot for different applications.
