A Guide To Robot Arms

The word robot isn’t native to the English language. The language from which the word was borrowed means forced labor. Robots work in different industries, working for hours, performing difficult and dangerous tasks that most people can’t do. So in that sense, the phrase force labor fits. However, another description for a robot is a machine that performs specific tasks with accuracy, precision, efficiency, and speed.

A robot is commonly used for manufacturing, production, and assembling processes that require peak performance. In such industries, tasks are repetitive, and consistency in production is crucial. Robots can deliver quality while performing tasks over extended periods.

They have made human work much easier. The presence and usefulness of robots forever change industries such as automotive production companies, engineering, and agricultural industries.

What Is an Industrial Robotic Arm?

There are many types of robots and many tasks that robots can perform. The structure, mechanism, and design determine what it does.

A robot arm is also known as an articulated robotic arm. Robot arms are usually stationary, meaning that they are bolted to a specific spot like the floor, wall, ceiling, or another surface. Although it stays in place, robot arms are not void of movement. The structure of an industrial robotic arm typically has several joints, articulations, and manipulators: these work together, creating a movement and functionality similar to that of a human arm.

Robot arms can work as extensions of larger robotic pieces or function independently.

Past Limitations Of Robot Arms

Robots have evolved, and many no longer require close or constant supervision. They can also perform a wider range of tasks to accomplish narrowly defined tasks.

Previously, robot arms needed teaching and further development to perform more complicated tasks such as picking up a single item from a specific location in a specific direction.

This problem was due to the robots’ inability to recognize and differentiate one object from another. They were only able to recognize general areas but not pinpoint specific positions. Also, the robots could not adjust their grip to match the specific object it was interacting with. Essentially, it became a limiting factor for the robots making them less effective and slower.

These days, robot arms have seven sections joined by six joints.

For example, the robotic arm is frequently used in manufacturing roles. A typical robotic arm comprises seven metal segments joined by six joints. The robots have step motors that are controlled by computers. Essentially, motors are joined to each joint, and the computers cause the motors to rotate by controlling them individually.

The advantage of step motors is the range of movement they provide. They allow the robots to gain momentum in precise movements, enabling the computer to precisely control the movement. Robots can now move in the same way repeatedly. With the help of motion sensors, computers can control the movements accordingly.

Applications of Robotic Arms

Robots have many uses in a business. Let’s look at a few of them.

  1. Material Handling

Robot arms handle the material in a business. They move items from one place to another, for instance, packing and storing items correctly for easy transportation.

2. Assembly

Another use for robot arms is for assembling items. Assembly mostly works in a production line. It helps the production process if tasks are automated. It essentially lowers the chances of injuries or other accidents while increasing company productivity.

3. Welding

Robots can perform both simple and complex tasks. Companies dealing with advanced tasks like the automotive industry would need robots to weld, ensuring that only the best quality products are made.

Benefits Of Robotic Arms

From the first invention to their remarkable revolution, robots have played a key in today’s society. Companies and entire industries have enjoyed several benefits from robot arms.

1. Speed

There is a never-ending need for more production at faster rates in competitive markets. Humans try to work quickly, but they can slow down due to fatigue or even boredom. Robots, on the other hand, never need to take a break. They can work at incredible speeds hence achieving a lot very fast.

2. Safety

Many workers in factories face danger every day. Most environments aren’t safe. They may involve hazardous chemicals, exposure to very high temperatures, or heavy items. Workers in such environments are at risk of getting injured almost daily.

3. Efficiency

In addition to speed, robot arms are efficient machines. They can continually 24/7. Since they are machines, they don’t need days off or recess, meaning that production rarely needs to be stopped and essentially that businesses maintain production and other tasks at a steady pace. Output is generally increased, and the company can meet deadlines.

4. Precision

Robot arms perform various tasks, including assembling parts, picking and placing, etc. These are tasks that require accuracy and no mistakes. A robot can perform tasks to perfection with almost no human help. As a result, businesses can have consistency in their products.

5. Flexibility

Usually, business growth is dependent on the staff, ie, if the company changes, the staff have to change along with it. If the staff cannot cope with the changes, new workers will need to be employed. Robots work differently from humans. They can be repurposed when changes come to fit into the new activities. Robots are essentially be programmed to do various tasks in different environments. Their flexibility is what a company needs when faced with changes in the priorities or the market.

6. Automation

Robots are programmed to perform certain tasks automatically. Normally, automated tasks would be repetitive, such as picking up and placing items, applying paint, and lifting heavy boxes. With automation, companies can reduce time spent on repetitive tasks, increase efficiency, and increase speeds.

Wrapping It Up

Robots make the lives of so many people easier by providing efficient, accurate and a fast production of products.

Even though the robotics industry has seen tremendous growth over the years, there is still so much growth potential. The future holds more connections in industrial environments. It also promises that robotic arms will have more abilities in the future.
