Cartesian robots are capable of moving in multiple linear directions. Cartesian robot arm configuration has three linear and no rotational axes. It is suited for operations that require essentially up-and-down motions, as in palletizing or machine tending for which precise positioning is required. They are often used for pick-and-place applications, machine tool loading, and stacking parts into bins. Other applications include the manufacture of starter motors, wiper motors, instrument clusters, electronic fuel injection systems for cars, as well as cell phones, pressure sensors, printed circuit boards, and navigational systems.
