Robot manipulators are available in several different styles/configurations. This page shows five industrial robot configurations and their respective work envelpopes. Several videos are included showing the robot configurations in-use.
The first industrial robot, the Unimate, was a spherical robot. Sperical robots are rarely (if ever) used today.
Cylindrical robots are not widely used today.
The video above shows a cylindrical robot.
Cartesian or Linear
Cartesian robots are perhaps the easiest and least expensive robots to build. They can be made using linear actuators (electric or pneumatic) and programmed using a PLC or PC. The axis configuration of Cartesian robots provides good rigidity compared with other robots configurations.

SCARA (Selective Compliance Articulated Robot Actuator) robot configurations are extremely fast and are frequenly used in electronics assembly applications.
The video above shows a SCARA style robot manufacturing electrical capacitors.
The video above shows a SCARA style robot placing loaves of bread into boxes.
The video above shows several SCARA style robots making mascara (cosmetics robot application). This video shows much more than just robots... look at the end of arm tooling and part conveyance mechanisms used.
Articulated robots are widely used in industry today. They are very versatile and are the most common robot configuration used in manufacturing industries today.
The video above shows an articulated robot packaging potatoes.
The above video shows articulated robots assembling an engine.
