Examples of Industrial Robots

An industrial robot is defined as a machine that features a multipurpose manipulator that is automatically controlled and programmable in three or more axes. Industrial robots are also defined as reprogrammable machines that may be stationary or mobile. Industrial robots are used to automate production related tasks with the majority being used in manufacturing settings.

There are many different types of robots that fall under the definition of an industrial robot. Industrial robots are classified according to their structure or architecture. Below is a look at examples of the most common types of industrial robots.

• • Articulated Robots - An articulated robot is one whose robotic arm consists of at least three axes. Articulated robots typically feature a rotating base attached to a single robotic manipulator. They are the most common type of industrial robot as they are the most versatile. The FANUC Arcmate 120ic is an example of an articulated robot. Articulated robots can vary greatly by size, reach, payload, and axes. Most have four to six axes. The ABB 120 is an example of a compact articulated robot. The Motoman ES165D is a larger articulated robot that is ideal for heavy payload applications. Examples of applications automated by articulated robots include palletizing, assembly, welding, material removal, and material handling.


• • Cartesian Robots - A cartesian robot is defined as one consisting of a robotic manipulator with three perpendicular axes and is attached to a coordinate system such as a linear track. These robots are an example of a mobile industrial robot. Cartesian robots can also be referred to as gantry robots. Due to their coordinate system, cartesian robots are ideal for material handling applications such as robotic pick and place. Their track system provides mobility that allows them to quickly transfer parts from one point to another.


• • Delta Robots - Delta robots are those that consist of three parallel robotic arms that meet at a single point. The arms of a delta robot move simultaneously to control a single EOAT. Unlike most types of industrial robots, the base of a delta robot is attached above the robotic manipulator. The FANUC M-2ia is an example of a delta robot. Delta robots are compact with slender arms and low payloads. Their design allows for agile movements and fast speeds. Examples of applications automated by delta robots include pick and place and part transfer. These robots may also be called parallel or spider robots.


• • Collaborative Robots - Collaborative robots feature a similar structure to articulated robots but with rounder edges. Collaborative robots are designed to operate alongside humans. Their rounded exterior is just one of many safety features that make it possible for them to operate around humans without safety barriers. Built-in force sensors and the elimination of pinch points are some of their other safety features. The Universal UR5 is an example of a collaborative robot or cobot as their name is often shortened to. Examples of collaborative robot applications include assembly, machine tending, material handling, inspection, and material removal.
