There are different categories of robots like articulated arm, polar, cylindrical, gantry, cartesian and scara. Scara and cartesian robots are the most popular based on simple applications.

Cartesian  robots have the most rigid structure that allows them to control reasonably high loads. They are used for pick and place tasks, machine tool loading, and stacking parts into bins.

The Cartesian coordinate robot is used to place an extensive selection of end-effectors like: Automatic screwdrivers, Automatic drills, Dispensing heads, Welding heads, Waterjet cutting heads and Grippers. The Cartesian robot has a simple and basic design that make it attractive in manufacturing. The Cartesian system reduces downtime and maintenance costs based on axes that can be replaced. Also, the whole system can be disassembled into its parts or reconfigured for different applications. Cartesian systems are less expensive than complex robots.

Cartesian robots have three particular directions X, Y and Z. They can move in multiple linear directions. Cartesians robots are used for assembly of electronic parts. Cartesians robots have other uses like manufacturing of starter motors, wiper motors, instrument clusters, electronic fuel injection systems for cars, cell phones, pressure sensors, printed circuit boards, and navigational systems.
