Robots are no longer just found in sci-fi. With the development of technology, robots are becoming more and more integrated into our daily tasks. This helps humans to avoid repetitive, dangerous, difficult or even impossible tasks.
The different types of robot arms, which are one of the main parts of an industrial robot, are often referred to as robotic manipulators. These robotic arm types are programmable and are connected via joints or axes to allow rotational or linear movement.
The end-effector must be moved and controlled by robotic arms to finish a particular application. Different types of industrial robot arms have subsequently improved safety and efficiency in industries including manufacturing, military surveillance and armament, healthcare, transportation, and research.
A collection of robotic devices is collectively referred to as "robotic arms." The uses of these several robot types frequently overlap. However, each kind has unique features that often allow it to be more effective than other robotic arms for particular jobs. Various robotic arm types include:
Articulated arm
Six-axis arm
Collaborative robot arm
SCARA arm
Cartesian arm
Cylindrical arm
Spherical/Polar arm
Parallel/Delta arm
Anthropomorphic arm
Dual-arm
Several manufacturers and industry experts are using different types of robotic arms to automate their tasks, enhance their workers' safety, and increase their overall efficiency and productivity. Moreover, many robotic arm types can reduce wastage and operating costs as well. Industrial robots are becoming more and more prevalent in various types of industries. This section will explore the main types of industrial robots available on the market.
An articulated robot arm resembles the human arm and allows mechanical movement and configuration. It is one of the most common types of robotic arms for industrial automation. It features a single mechanical arm attached to a base with a twisting joint.
Six-axis robots are the most common type of articulating robot, and they generally feature four to six axes, allowing for a wider range of motion. They can automate many different robotic applications, including arc welding, spot welding, painting, assembly, material removal, material handling, palletizing, and many more.
Cartesian robot arms are also known as linear robots or gantry robots. These are the types of industrial robots that work on three linear axes using the Cartesian coordinate system (X, Y, and Z). This means they move in straight lines on three different axes (up and down, in and out, and side to side). This is why this type of robotic arm is quite popular amongst industrialists and manufacturers who are looking for higher flexibility in their configurations.

These robots provide users with the ability to adjust the speed, precision, stroke length, and size of the robot arm. Cartesian robots are positioned in the market for small applications and are often used for CNC machines and 3D printing.
Cylindrical robots are another type of robotic arm designed around a single-arm capable of moving up and down vertically. They have a rotary joint at the base and a prismatic joint to connect the links. These robots are very compact and cover small and simple tasks such as assembly, machine tending, or coating applications. This type of robotic arm is achieved with a rotating shaft and an extendable arm that supports vertical and sliding movements.
Delta robot arms are also referred to as "parallel robot arms" as they facilitate three arms connected to a single base mounted over a workspace. These types of robot arms have high-speed options and are thus used for automation.
Moreover, these robot arms have a unique design in the form of a dome shape that is capable of delicate and precise movements at high speeds. This is because all three arms directly control every joint of the end effector. These types of robotic arms are a great choice for applications in the food, pharmaceutical, and electronic industries.
Polar robots, also known as spherical robots, feature a base coupled to an arm with two rotational joints and one linear joint. The robot's axes combine to create a polar coordinate, enabling it to have a spherical work envelope. One of the first industrial robot categories to ever be created is the Polar Robot. Die casting, injection moulding, welding, and material handling are popular uses for polar robots.
Selective Compliance Assembly Robot Arm or Selective Compliance The Articulated Robot Arm is referred to by the abbreviation SCARA. The three-axis (X, Y, and Z) motion of SCARA robots is combined with rotational motion. Compared to Cartesian robots, SCARA robots perform better in lateral motions, move more quickly, and integrate more readily. SCARA robots are typically employed for biomedical applications, palletizing, and assembling.

Robotic arms are the most common form of robot technology in the industry. Read on to learn the benefits of this technology and see if it is right for you.
Robotic arms are one of the most identifiable pieces of robotic machinery in industrial settings. They tend to fascinate with their impressive feats of speed and strength, but their uses and how to apply them can be a mystery. This article will broadly describe the place of robotic arms in industrial applications to give you a better understanding of if they might be the right choice for you.
Topics discussed in this article include:
The term 'robotic arm' broadly describes a group of robotic mechanisms. These different robot types tend to have similar applications. However, each type has distinctions that typically lead to it being optimized for certain tasks over other robotic arms. Types of robotic arms include:
Articulated arms are general-purpose robotic arms with 5 or more joints or degrees of freedom. The articulated arm is an umbrella term for many other robot types. For instance, a six-axis robot is an articulated arm with six degrees of freedom. Articulated arms cover the broadest range of robot types used in industry and include six-axis and collaborative robots. You will find an example of this robot type in the banner image of this article.
Six-axis robots are the most common articulated arm. This also makes them the most common robotic arm used in industry today. Thanks to their flexibility, they are a great general-purpose robotic arm. This gives the six-axis an impressive list of uses. The six-axis robot is the most easily identified industrial robot.
The collaborative robot is a robotic arm purpose-built for hybrid work. This means it is designed to work near humans. Certain safety features allow for significant risk reduction in hybrid work environments. This is a relatively new robot type and its uses are still being explored. Collaborative robots are becoming more prominent in the industry as more manufacturers are being exposed to their benefits. The future is exciting for collaboratives.
SCARA robots are selectively compliant robot arms. This means they don't have the same flexibility afforded to articulated arms. This limits them in some respects but gives them certain advantages over articulated arm types.
Cartesian robots are rigid systems that move around in a 3D coordinate plane. These robots are typically constructed of 3 linear actuators. One actuator moves left and right in the x-axis. An additional actuator is attached to the x-axis actuator. This actuator moves up and down in the y-axis plane. A final actuator is attached to the y-axis member and moves back and forth in the z-axis plane. Cartesian robots are positioned for small applications.
Cylindrical robot arms are designed around a single arm that moves up and down a vertical member. This vertical member rotates the arm horizontally. The arm can extend and retract to perform its task. These robots are very compact and are deployed for small and simple tasks.
The first modern industrial robot was a spherical (polar) robot. This robot type has a simple design that isn't as common today as it once was. Spherical robots are similar to cylindrical robots except they swap the vertical linear axis with an additional rotary axis. This axis allows it to rotate vertically. It was designed for simple tasks that don't require high speed or complex motion.
Parallel/Delta robots are high-speed options for robotic automation. These robots' unique design allows them to reach incredible rates of speed. The delta robot is a great choice for high-speed and lightweight tasks.
Anthropomorphic robots are a rare sight in industrial settings. These robots boast two or more arms and a friendly face. They are often deployed in collaborative environments where they are working in near proximity to human operators.
