The design of SCARA robots aims to mimic a human arm’s actions to automate manufacturing processes such as assembly and loading/unloading tasks. They offer unmatched speed and precision that other big industrial robots cannot achieve. The main idea is to obtain the benefits of a human worker at higher speeds without fatigue. Incorporating SCARA robots into your manufacturing line is among the most affordable methods to increase your production speed.
EVS SCARA robots have been used for applications that require fast and effective pick and place performance. These include food processing, automotive assembly, electronics manufacturing, and pharmaceutical manufacturing applications. They can pick, place, move, pack, and unpack components easily which minimizes the space they occupy on the factory floor.

So what does Selective Compliance in the acronym SCARA mean? In robotics, the term compliance is defined as a robot’s capability of being flexible in at least one of its joints. It can also refer to the flexibility of the robot’s mechanical structure.
Compliant robots give way to your touch once you push them. They will not hold steady or push back. This unique configuration and design of SCARA robots allow them to handle a wide array of tasks in material handling applications.
The operator sends commands to the robot’s controller through communication ports such as digital I/O signals, etherCAT, and ethernet ports.
SCARAs are typically mounted on pedestals. They use vision systems, sensors, and motion controls to locate and pick up items accurately.
SCARA arms use 4-axis joints that allow them to move horizontally and vertically. They can move in the X and Y planes but are rigid in the Z plane. However, the robot’s end at the Z-plane, the “wrist” where the end-of-arm tooling is connected, has an axis that can rotate but cannot tilt.
SCARAs have adjustable horizontal movement. However, since the arms of SCARAs are levers, their reach is limited. Moreover, their joints handle the majority of the load when their arms extend so they need high-torque motors and robust bearings.
How can SCARAs benefit your business? SCARA robots are chosen because of these 4 main reasons:
Generally, SCARA robots can complete tasks at higher speeds with optional cleanroom specifications. They are quicker compared to other industrial robots and you can operate them in different industrial environments.
SCARAs also have the best performance among all types of robots when it comes to repeatability. High repeatability is important in assembly applications that require tolerances within a few microns. Examples are circuit board assembly tasks and moving needles into small grooves for dispensing.
Aside from speed and repeatability, SCARAs offer excellent verticality and linearity that help them perform various tasks precisely at fast speeds. With the help of vision systems, they can execute identification, sorting, and inspection tasks smartly which helps in reducing defect rates to effectively deliver consistent quality.
Lastly, SCARA robots are designed for applications that require smaller operation fields where there is limited floor space. They have a compact layout so you can easily re-allocate them for other applications.
SCARAs offer the best price-performance ratio when it comes to high-speed applications. They are suitable for businesses that are looking for cost-effective automation solutions. They are cheaper compared to delta robots which are another type of high-speed robot with multiple arms.
The cost of SCARA robots can range from USD 6,000 to USD 14,000 but can reach up to USD 20,000. The price of your desired SCARA robot will depend on the following factors:
Below are the major tasks that low-cost SCARA robots excel at:
SCARA robots were originally made for small assembly tasks that require high-speed performance. Examples are tasks in electronics manufacturing. The selective compliance of SCARA robots allows them to perform insertions easier compared to other robots without the need for complex programming.
SCARA robots are the cheapest and fastest machines for pick and place applications. Although Delta robots can beat their speed, SCARA robots are easier to set-up because you do not need to mount them above your workspace like Delta robots.
Soldering is another important task why SCARA robots are popular in electronics manufacturing. When equipped with the right end-of-arm tooling, they can produce consistent solder quality with improved efficiency compared to manual soldering.
3D printing is recently becoming popular in the robotics industry. There are 6-axis robots that can print bigger objects using 3D printing technologies. SCARA robots can be used in these applications for small scale printing applications.
Since SCARA robots can produce highly precise results, they are ideal for drawing and laser engraving tasks. A lot of end-of-arm tooling has emerged in the market over the past years that allow manufacturers to integrate laser engraving devices into small robots like SCARA robots.
