Cartesian
Also known as rectilinear or gantry robots, Cartesian robots have three linear joints that move in different axes (X, Y, and Z). This unique, rigid structure enables simple movements with advanced precision and repeatability. These advantages make Cartesian robots ideal for assembly line applications, such as picking up and moving bottles. Since they do not require extensive movements, they are fairly inexpensive robots and are some of the cheapest assembly line automation solutions.
