COMPLETE REVIEW OF SELECTIVE ASSEMBLY ROBOT ARM (SCARA)

Have you ever heard of SCARA? In the modern world like today, technological developments are becoming increasingly sophisticated. There are more and more terms appearing in the world of technology, from AI or Artificial Intelligence to SCARA or Selective Compliance Assembly Robot Arm. 

In short, we can call it a Robotic Arm or Hand/Arm Robot, which is a type of industrial robot that is useful for carrying out assembly tasks with high accuracy and speed. Check out further discussion regarding the SCARA Robotic Arm below!

Who Invented SCARA?

This Robotic Arm has quite a long history. Initially, in 1977, a professor from Yamanashi University named Professor Hiroshi Makino was inspired by an event. The event was held at the International Symposium in Tokyo, Japan and discussed Industrial Robots.

At that time, Hiroshi witnessed an inspiring revolutionary discovery, namely the SIGMA robot. After that, Hiroshi began to form the SCARA Robot Consortium, which consists of 13 Japanese companies to develop self-assembling robots through special research.

A glance at the Selective Compliance Assembly Robot Arm (SCARA)

The SCARA Robotic Arm has a unique way of working, you know, it has a unique configuration with 2 arms. One arm can operate in a horizontal plane and the other arm in a vertical position.

This configuration allows the robot arm to move more flexibly, stably, and allows for quick and accurate pick and place movements.

Many factories or industries use this cool technology for packaging, sorting, material processing, and even assembling electronic components.

The main advantage of SCARA is its ability to maintain stable vertical and horizontal movements, making it suitable for assembly and material movement operations that require fast and precise movements.

Before it started to be used in the industrial world, researchers from industry to university students had done a lot of research on this Robotic Arm, you know!

One of them is a thesis on Selective Compliance Assembly Robot Arm at Gadjah Mada University which you can access via the UGM Repository website.

This research was conducted to analyze the kinematics and dynamics of a 4 DOF SCARA robot using V-REP and MATLAB simulations.

The goal is to increase efficiency and productivity in the manufacturing industry by designing, analyzing and simulating SCARA robots.

There is a number of research data, scientific journals, and other theses and theses that carry the Robotic Arm theme. For example, a discussion of the design and simulation of the Selective Compliance Assembly Robot Arm (SCARA).

his research discusses the design and simulation of Robotic Arms used in industry for Material Handling (Packaging, Assembly, and Pick and Place). 

Based on research journals which can be accessed in the ITS Repository, the Robotic Arm also has the ability to pick up objects commanded by voice commands, the success rate has reached 78%.

Through some optimization and more research, this success rate can be increased further in the future.

Differences between SCARA and Other Industrial Robot Arms

The standard industrial robot that is widely used in the world of manufacturing is the 6-axis robot, the two have quite big differences. Here are some of the main differences:

1.Design

Selective Compliance Assembly Robot Arm (SCARA) only has 4 axes so movement is limited, the design is also simpler and smaller. Meanwhile, other industry standard robots have 6 axes which allow them to move freely in various directions. 

2. Range of Motion

SCARA with its 4 axes certainly has limited movement, it is more suitable for work in the vertical plane of motion because the arms are designed that way. This makes SCARA robots more suitable for jobs that require precise movements within a certain work space and less suitable for jobs that require complex movements.

3.Size

Selective Compliance Assembly Robot Arm (SCARA) has a smaller and more compact size than a 6-axis robot arm. This means that the SCARA Robotic Arm can be integrated into small work areas. 

The Popularity of the SCARA Robotic Arm and Its Influence in the Industrial World This Robotic Arm is a type of industrial robot that is currently popular, especially in the manufacturing and assembly industry. In general, this type of robot has 4 axes and 2 parallel arms.

This robot has the ability to move freely and is able to maintain rigidity in its 3 axes, while the last axis is flexible. 

This flexibility allows the robot arm to perform tasks such as pick & place, sorting goods, and even assembly. Currently, many well-known manufacturing companies in the assembly sector have switched to using SCARA Robotic Arm technology.

Even though it is not yet 100% integrated with Robotic Arm, its use is becoming increasingly common. 

Advantages of Using SCARA Robotic Arm

The use of robots turns out to provide many benefits for the world of large-scale manufacturing. ts simple design is able to speed up the work cycle, its accuracy is also good, and it is able to repeat work with more precise processes and results than other types of robots.

 

In fact, this robot is able to work well on assembly work with minute or small details. Considering its simpler design, the price of SCARA is also cheaper. This minimalist design means costs for production and maintenance are minimal. 

 

Its high accuracy and precision make this type of robot capable of completing detailed tasks quickly and with minimal errors. 

 

Disadvantages of Using SCARA Robotic Arm

 

Matching Jobs Are Automated Using SCARA Several types of work that can be automated using the SCARA Robotic Arm are: Assembly such as assembling electronic equipment, installing nails and screws, and installing small components.

• Pick and Place: pick and place certain objects from one point to another.
• Packing: Packing products sent or stored. You can program the SCARA Robotic Arm to pick up and place products in boxes and equip them with sensors.
• Distribute components or fluids with a high degree of accuracy.
• And so on according to function. 
  

Conclusion

 

From the discussions above, we can draw several conclusions. CARA is Selective Compliance Assembly Robot Arm or robot arm. This type of robot has 4 axes with movement in the X-Y and Z planes, its 360 degree rotation originates from the Z axis. 

 

SCARA has a smaller size, minimalist design, more economical price, more accuracy, faster, and is able to repeat work with precision.

 

Therefore, the SCARA Robotic Arm is more suitable for use in assembly, sorting and pick and place work. However, compared to standard 6-axis industrial robots, SCARA also has several disadvantages, namely limited movement space (dominantly horizontal) and lower load carrying capacity.

 

In choosing the right 4-axis SCARA Robotic Arm model, you can consider several things. Starting from the scope of work and footprint, accuracy, to speed.
