Different Types of Robots

Different types of robots serve different purposes in today's society. The future robots that you see in sci-fi films might not be around yet, but industrial robots play important roles in manufacturing plants, the military and even medical applications. Ready to learn about the different types of robots?

The Cartesian robot.
The Cartesian robot is one of a series of industrial robots, so named because it uses a Cartesian coordinator to operate the three prismatic joints of its arm. The Cartesian robot has uses in pick-and-place applications, arc welding, machine tools and applying sealant.

A cylindrical robot.
A cylindrical robot looks exactly how it sounds; a robot with axes that form a system of cylindrical coordinates. The cylindrical robot also belongs to the family of industrial robots, and it is good for machine tools, assembly work, spot welding and die casting.

The spherical or polar robot.
The spherical robot is capable of a polar coordinate system, in a radius around the machine and up or down. This is another industrial robot, and it's used in many of the same applications as the cylindrical robot.

Articulated robot.
An articulated robot is a robot with an arm that has multiple rotary joints, at least three, but sometimes more. An articulated robot can perform a different range of motion from the cylindrical or spherical robots, and while it's used in similar applications, it is suitable for operations that require different types of movements.

Parallel robot.
A parallel robot is a robot whose two arms have concurrent joints; either prismatic or rotary. The parallel robot is useful in applications that require two arms that can move simultaneously, including handling cockpits in flight simulators.

SCARA robot.
A SCARA robot is a robot with parallel rotary joints that enable the robot to operate in a plane. It's used in the same types of industrial applications as the other industrial robots.

Robots in military applications.
Military robots resemble the future robots you'd see in movies such as the "Terminator" series, with equipment that can go into battle without human involvement. Robots in military applications are still in the top-secret phase, and little is known about current levels of development.

Robots in medical applications.
Robots are also useful in life-saving medical applications. Robotic surgery is a growing area in the medical field, and it's an area in which robots have been utilized effectively. Robots can do everything from making smaller, more precise incisions to enabling doctors to operate remotely. Robotic surgery continues to advance as technology improves, and it is becoming a cornerstone of the surgical field.

Robots in household applications.
Robots are also beginning to become popular in household domestic applications. iRobot has a Roomba vacuuming robot, as well as a whole line of robots designed to pick up dirt and clean and mop floors. These types of domestic robots are huge time-savers, and they make it easy for people to focus on more productive tasks besides simply cleaning the house.
