SCARA robots, which stands for Selective Compliance Assembly Robot Arm, are highly popular and user-friendly industrial robotic arms used in various industries, especially in manufacturing and assembly applications. These robots have the ability to move freely and maintain stiffness in three axes while being compliant in the final axis, making them suitable for tasks such as pick and place, sorting, and assembly.
The history of SCARA robots dates back to 1977 when Professor Hiroshi Makino of Yamanashi University attended the International Symposium on Industrial Robots in Tokyo, Japan. Inspired by the revolutionary SIGMA assembly robot showcased at the event, Makino formed the SCARA Robot Consortium, consisting of 13 Japanese companies, to further improve assembly robots through dedicated research. The consortium quickly developed and tested the first prototype of a SCARA robot in 1978, followed by a second version two years later. The commercial release of the first SCARA robot in 1981 revolutionized industrial production processes worldwide.
SCARA robots typically feature 4 axes, with 2 parallel arms capable of moving in a single plane and a compliant final axis at right angles to the others. Their simple design allows for quick movements while maintaining precision and accuracy. They are easy to program compared to industrial robotic arms with 6 degrees of freedom, and their fixed joint positions make them predictable. SCARA robots are versatile and can enhance productivity, accuracy, and task speed simultaneously.
The advantages of using SCARA robots are numerous, particularly for large-scale production applications. Their simple design enables faster cycle times, impressive positioning accuracy, and high repeatability. They excel in smaller environments where precision is crucial, making them popular for electronics assembly and food manufacturing. SCARA robots are also easy to program, especially when using RoboDK as the robot programming software.
However, there are some drawbacks to consider when using SCARA robots. While they offer high speed, their payload capacity is limited compared to other robot types, with the highest payload SCARA robots capable of holding only about 30-50 kg. Additionally, SCARA robots have a restricted workspace, limiting the size of operations they can handle and the flexibility of task orientations.
Despite these drawbacks, now is a great time to consider using SCARA robots. They are cost-effective and highly flexible options for various needs. RoboDK has recently made updates to the software to further improve SCARA programming, including an enhanced inverse kinematic solver for SCARA robots. This feature allows for easy reversal of any axis, simplifying the process of mounting the robot upside down or in different orientations.
Choosing the right SCARA robot can be challenging due to the wide range of options available. It’s essential to define your needs before selecting a specific model to ensure you maintain their favorable price-performance ratio. RoboDK offers a simulator where you can test multiple SCARA models by downloading them from the Robot Library and testing them on a mockup of your application.
In conclusion, SCARA robots are popular and easy-to-use industrial robotic arms used in various industries. They have a collaborative history and offer advantages such as fast movements, precision, and ease of programming. While they have limitations in terms of payload and workspace, they are still suitable for a wide range of tasks. Now is a suitable time to consider utilizing SCARA robots, especially with the advancements in programming capabilities.
