Industrial Robot- ALio Industries

Industrial robots: Science fiction movies and literature has always given us glimpses of robots and their uses. But today these industrial robots are very much a part of our lives. They have become an important part of our workspace.

You will find many different types of industrial robots. These have helped to ease down the load on the operators. They have not just made work easier, but they have also help in bringing down production time, helped in giving accurate solutions and have helped to boost the revenue of companies.

The most commonly used robot configurations are articulated robots, SCARA robots, delta robots and cartesian coordinate robots, (gantry robots or x-y-z robots). In the context of general robotics, most types of industrial robots would fall into the category of robotic arms (inherent in the use of the word manipulator in ISO standard 1738). Robots exhibit varying degrees of autonomy:

  • Some robots are programmed to faithfully carry out specific actions over and over again (repetitive actions) without variation and with a high degree of accuracy. These actions are determined by programmed routines that specify the direction, acceleration, velocity, deceleration, and distance of a series of coordinated motions.
  • Other robots are much more flexible as to the orientation of the object on which they are operating or even the task that has to be performed on the object itself, which the robot may even need to identify. For example, for more precise guidance, robots often contain machine vision sub-systems acting as their visual sensors, linked to powerful computers or controllers. Artificial intelligence, or what passes for it, is becoming an increasingly important factor in the modern industrial robot.

What are Industrial robots?

This is basically a robot arm. It is used in different manufacturing processes. These automated systems work on 3 or more axes. These robots are reprogrammable. You will find that there are different types of industrial robots. Each of them has its own explicit features.

Types and features:

The industrial robots can be classified on the basis of different criteria. These are the type of movement, architecture, application and brand. These days the collaborative criterion is also taken into consideration. One needs to connect with a company like Alio Industries, who are known to provide solutions to the customers based on their requirement.

1. Robots based on the type of movement:

  • Cartesian robots whose 3 axes of control are linear, and these are at right angles to each other. These robots will move in a straight line.
  • SCARA robot that is Selective Compliance Articulated Robot Arm can do a rotation around the vertical axis in addition to the 3 translational.
  • Six axes robots have six degrees of freedom and they have more flexibility. Therefore, they can be used in a number of applications.
  • Redundant robots can position the tool in a given position and in different postures.
  • Dual-arm robots will have 2 arms, and these can work together.

2. Robots based on the type of application:

The specifications of this type of robot will depend on the application. The movement, controls, accessories etc. will vary as per the application. For example, an industrial robot that is used for assembling operation needs to have very good speed. It must have a very high degree of precision and it must be able to operate in a small space.
The different types of industrial robots based on application are welding robots, painting robots, Palletizing robots and assembly robots.

3. Robots based on the architecture:

These are classified into serial and parallel robots. In serial robots, the linkages will go from the base of the robot. Parallel robots or spider robots have high acceleration and have a small workspace.

4. Collaborative industrial robots:

These are the latest type of robots and they can collaborate with human beings.

History of industrial robotics:

The history of industrial robots goes back to the 1930s. In the year 1937, Bill Griffith P. Taylor completed the first industrial robot which conformed to the ISO standards. In the late ’70s, people started focusing more on robotics. It was during this time that many US companies ventured into this field.

We can say that the modern age of these robots began from the 1980s and it continues till date. In 1981 Takeo Kanade came up with the first robotic arm which had better accuracy and speed as compared to the earlier versions of industrial robots.

In 1988 Yaskawa America Inc came up with Motorman ERC control system which controlled 12 axes. In 1994 Motorman ERC control system was upgraded to support 21 axes. In 2008 the first collaborative robot was installed.

What is an industrial robot used for?

These robots are useful in different industries to overcome different challenges in different applications. They can be used in material removing, assembling, welding etc. One can also use them in a non-destructive inspection. There are mobile robots that can be used to transport large structures in certain industries like the aerospace industry. These robots help to improve safety and they will also help in improving inefficiency.

Industrial robot applications:

These types of robots can be used in different applications. They are mainly used in material handling. They can also be used in welding. There are many other robot applications.
They can be used in appliance automation, 3D laser vision, grinding, laser cutting, drilling, cutting etc. The flexibility of the robot, reach, payloads etc. will vary depending on the application. A company like Alio Industries has the expertise to fulfill the customized requirement depending on the application.

Market structure:

According to The International Federation of Robotics in the year 2017, there were 2,439,543 operational industrial robots. In the year 2018, China alone sold 154,032 units of industrial robots. By the year 2021, the number of industrial robots across the globe is expected to rise to reach 3,788,000.

The largest user of industrial robots is the automotive industry. Their market share is around 30%. The electrical and electronic industry has 25% market share. These robots are also used in other industries. This includes metal, machinery, rubber, plastic, food, textiles, leather industry etc.

Advantages of industrial robots:

  • Since these robots can complete tasks faster, they will help in improving efficiency.
  • They have better accuracy and hence they help to improve the quality standards
  • Industrial robots can work for long hours
  • They improve productivity and they increase the profitability
  • Improvement in the working conditions from the point of view of safety.
  • They can perform tiring and laborious tasks with ease.

Disadvantages of Industrial Robots:

  • The implementation of industrial robots is an expensive affair. The company has to be willing to make a huge investment.
  • This is a highly advanced technology. So, for the set up you need expertise. The operation staff will have to be given proper training.
  • Industrial robots do have their own limitations in performing certain tasks.

Industrial robots can surely help in easing a lot of load in different industries. But one has to make the selection of the robot prudently. One has to take into consideration the application for which the robot has to be used. You also need to have clarity about the specifications.

It is always better to choose experts who are known to manufacture bespoke industrial robots. One can seek advice from such experts and can then choose the industrial robot as per their specific needs.
