Everything You Need to Know About Industrial Robotic Arms


For thousands of years, human arms have been assembling and putting things together in factories. However, due to technological advancements, new arms have been developed, industrial robotic arms. These artificial arms work in the same respects as those of humans but only at a more accurate and fast rate.

The industrial robotic arm is one of the most common robots in the world of manufacturing. The robotic arm which is made of metal usually has four to six joints. It can be used for a variety of manufacturing applications including material removal, welding, and material handling.

What are industrial robot arms made of?

An industrial robot arm is usually made of cast iron or steel. The metallic arm is normally built from the base up, it either ends with a wrist or any other end effector that is required to perform the task chosen for the arm. Each joint of the robotic arm features motors which are rotated by a robot controller. Some of the larger industrial robot arms are operated by pneumatic and hydraulic means in order to lift heavy payloads.

The arm’s work is to move the end effector from one place to another while performing its duty. It may be taking off, putting down, picking up or welding an entire or part of a workpiece. Robotic arms can either be programmed to carry out one specific task or a variety of them. It all depends on the needs and specifications of the manufacturer.

A marvel of engineering

Because industrial robot arms react in a way that is similar to human arms, they are considered an engineering marvel. The robotic arm also has a close resemblance to that of a human arm and features an elbow, wrist, shoulder, and forearm. For instance, a six-axis robot comprises six degrees of freedom. This means, unlike the human arm which enjoys seven degrees of freedom, the robot arm can move in six different ways.

However, those are the only similarities between a robot arm and a human arm. The arms of industrial robots move at a faster rate when compared to those of humans. Without the proper precautionary and safety measures, this can be very dangerous to the human operator. For this reason, robotic arms are usually designed with some type of sensors or safety package that ensure safety for people.

Benefits of an industrial robot arm

Industrial robotic arms have quite a number of benefits especially to businesses that deal with monotonous tasks such as welding or material removal.  The arm of an industrial robot not only increases the manufacturing process’ speed but also enhances precision and accuracy. In this regard, they cut down on both labor and worker error costs.

Industrial robotic arms can perform a plethora of functions. While they can be used to weld n entire vehicle, stack heavy items and lift heavy loads, they can also be used for small tasks. For instance, the precision of an industrial robot arm allows it to put assemble even the smallest microchip or motherboard.

It is crucial for a business to pick out the correct industrial robot arm in line with the job it needs to handle on the production line. While some tasks might require larger robotic arms which are designed to provide more reach and stability, others require smaller ones for putting together tiny microchips.

Small robotic arms are ideal for machine tending, dispensing, assembly as well as pick and place. Similarly, they are used in a plethora of industries such as packaging, pharmaceuticals, food and electronics among others. They are designed to improve your business’ production line in many ways.

With emerging trend in the robotics industry, industrial robot arms will continue to operate in the manufacturing industries for many years to come. As we wait for the introduction of the next lightning fast innovation, let’s enjoy this arm lifting and moving progress.
