7 Types Of Robot Arms And The Industries They Are Perfect For

Ever since the Industrial Revolution, there have been great strides in production technology. However, the most rapid and incredible changes in manufacturing started around 40 years ago, when the first robot arms were invented and they started replacing human workers in production lines. Incredibly, these innovations never stopped, and now there are many types of robot arms that are made for very specific tasks and industries. Here are 7 Types of Robot arms and the industries they are perfect for. 

1. Welding Robot Arm

The welding robot is very self-explanatory. It is designed to weld objects together and is extremely efficient and fast. Design-wise, most welding robots could move in three dimensions for rectilinear types, and even more planes with articulating versions. A high-heat torch is usually attached at the end of the arm, and the heat from the flames usually reaches thousands of degrees. This makes the heat so much more focused, and allows the welding robot to melt through metal. Welding robots are highly adaptable and could be used to fulfill a wide variety of welding processes including, arc, TIG, spot, resistance, and a lot more. A lot of industries use welding robots. These include the automotive, metal, and fabrication industries. 

2. Painting Robot Arm

Painting robots are highly accurate and efficient robot arms, that are specially designed for painting applications. Most painting robots have a five or six-axis motion. There are three for the base motion, and around three for applicator orientation. 

These types of robots are specially designed to standardize the painting process and eliminate the risk of human error that usually happens during manual spraying.  Aside from the highly maneuverable robot arm, it is also equipped with an automatic sprayer to provide a detailed finish. It also has automatic mixing equipment that will provide the sprayer with the necessary paint.  Painting robots are used by a good number of industries, although the most prevalent user is the automotive industry. Cars need to have a perfect sheen and finish, and painting robots provide the most consistent paint jobs. 

3. Palletizing Robot Arm

The palletizing robot arm is specially made for palletizing and depalletizing procedures. Palletizing is the act of stacking products onto pallets for easy transport, and depalletizing is the act of unloading these same pallets once they arrive at their destination. In order to accomplish this process, the palletizing robot is programmed to stack the products in a defined pattern, and it requires timing and precision in order for the palletizing robot arm to function properly. A majority of industries use the palletizing robot arm because products need to be moved in large quantities, and stacked in well-ordered patterns.

4. Assembly Robot

The assembly robot is technically the darling of most production lines because it is specially designed to put parts together at record speeds. These robots were first created to replace human workers, so their key attributes are speed and precision. The robot arms are very flexible, and there is very little chance that they would get snagged with one another.  They are usually attached to a production line and are easily reconfigured to fulfill a specific need. The assembly robot is usually controlled via a program and could work autonomously very well. The most common industries that use assembly robots are automotive, electrical, and hardware industries, because their products require a great deal of assembly.

5. Handling Robot

As the name implies, handling robot arms are meant to handle and move materials for transport and delivery. Handling robots offer a lot of benefits to most production line systems. However, its main attribute is increased uptime. Compared to human workers who have to take breaks during the handling process, robots could work for hours on end, just as long as they are properly maintained. They are also much faster and could handle heavier loads compared to human workers. A majority of industries tend to use handling robots, although delivery industries use them the most. 

6. Pick and Place Robot Arm

The Pick and place robot arm is designed to speed up the process of picking up parts or items and placing them in key locations. These robots are highly efficient and could handle very delicate objects without fear of damaging them. The pick and place robot arm is specially made to handle the stress of hours of work and is capable of making repetitive movements without breaking. The main usage of pick and place robot arms is to minimize the work for human workers, so they could handle more complex tasks. Pick and place robot arms could be configured according to the need of the moment. So the pick and place robot could also be reconfigured for packaging and bin picking applications. Due to the pick and place robot’s accuracy and speed, they are usually used by electrical industries to make the assembly process more efficient. 

7. CNC Robot Arm

CNC robot arms are high-precision robot arms that could accomplish very accurate movements. They are made for physically demanding tasks and could handle a lot of repetitive movements without getting damaged. Like other robot arm options, the CNC arm is meant to reduce human errors and prevent injuries during the production process. The CNC robot arm is extremely versatile, and it could streamline a variety of tasks such as assembly, material removal, machine tending, and packaging. This jack of all trade quality makes the CNC robot very popular throughout most industries. 


In the past few decades, robot arm technology has evolved a great deal. There are now robot arms that are specially made for specific tasks. These same characteristics also make them perfect for certain industries. By knowing these types of robot arms and the industries that they are best suited for, you will be armed with the necessary knowledge should you need to purchase one in the future.
