Applications Of A Robotic Arm

A robotic arm is a mechanically programmed device that is built to imitate the human hand. The robotic arm may be a complete unit in itself or maybe a part of a larger robot.

A robotic arm is linked with joints that allow a range of motions such as linear displacement and rotational motions. The joints are said to form a kinematic chain.

A robotic arm may be fitted with several end factors with the most common resembling a human hand with fingers. It is used to perform actions like picking, moving, and dropping objects from one point to another.

It is undeniable that robots have become part and parcel of everyday human life. They are intelligent and have made humans more productive in their everyday life.

Nowadays robots perform tasks that were previously done by humans and are adding a degree of perfection to them as well as speed.

A robotic arm has many applications and the following are some of them:

1. Welding

A robotic arm can perform different types of welding which are spot and arc welding

Welding is the process of binding two metal surfaces together by infusing a large amount of electric current at the point at which two metal surfaces come into contact.

The large current generates a lot of heat quickly that melts the metal sheets and upon cooling, they bind together.

By using a robotic arm to weld, you save human workers from weld burns and inhaling the hazardous fumes produced during welding.

2. Material Handling

A robotic arm can be utilized in handling different materials in different departments.

They can be used in packaging, assembly, and selection of materials to be used in a production process. They can also be used in handling hazardous and poisonous material that may harm a human being.

Using a robotic arm reduces labor costs and the dangers humans are exposed to.

3. Machine Tending

Applications Of A Robotic Arm

A robotic arm may be used in tending other machines i.e. it can be used to load and unload raw materials into other machines producing a product.

Some of these materials it handles may be very sharp or the machines into which these materials are being loaded may be dangerous to be operated on sight by a human. It reduces these risks faced by human beings.

4. Painting

A robotic arm can and is being utilized in the automotive industry in painting cars and panels.
It is highly preferred in place of a human for its high consistency and quality finish of every car. It paints all vehicles uniformly.

Because it suffers no fatigue, it can continuously work as long as there are cars to paint none stop.

By eliminating the human factor in the painting process, work may flow more steadily and production output is met.

Human beings also do not breathe in the toxic paint fumes which may lead to respiratory problems after a while therefore it can be said to have a positive medical factor to it as well.

5. Assembly

A robotic arm can be used in assembly lines anywhere.

They are most commonly used in vehicle assembly where they handle large and heavy parts that are joined to form a complete car.

By using a robotic arm in assembly, you eliminate the human risk of getting injured while in the assembly line. You also eliminate the human error factor for a robotic arm will perform the same task over and over the same way with the same standard and quality.

A robotic arm increases production output and reduces wastage of time.

6. Mechanical Cutting, Grinding, and Polishing

A robotic arm is a perfect tool to use when handling material that needs to be cut or polished.

Usually, the cutting, grinding, and polishing machines are dangerous to work with since they rotate at very high speeds. It requires one hundred percent of your attention at all times. A lapse in judgment or the wrong positioning of your hand may result in you losing it.

Therefore, using a robotic arm to perform the tasks above is the most logical and safest way of doing this work.

A robotic arm is also faster than a human for instance it may take a human being one and a half hours to polish a fabricated hip joint whereas a robotic arm can do it in less than five minutes.


A robotic arm is an important and integral of our everyday life, especially in the production industry. It makes work easier for human beings and profitable to the companies that have employed its uses.

If you want to make an impact in the production society, and global society at large, use a robotic arm.
