scara robot are used in a wide variety of industrial applications. They’re very fast, precise and easy to maintain. They also have fewer joints, which makes them ideal for applications where cycle times are critical. They’re a great choice for tasks such as screwdriving, and they excel at repetitive movements with high accuracy.
Unlike many other types of robots, SCARAs are designed to be compliant in the X-Y plane while remaining rigid in the Z direction. This enables them to handle a larger range of forces and work in environments that would otherwise damage or destroy other robots. They also have a built-in capability to detect and respond to unexpected forces that would ordinarily cause them to lose control. This allows the robot to stop or reverse position mitigating the initial contact and even dissipate some of the energy transferred from the force.
There are a number of different SCARA robots available on the market that vary in size and arm link ratio but all offer a consistent four-axis motion. They excel in pick and place operations due to their ability to move at high speeds with smooth and precise movement.
The selection of a specific robot type is often based on the requirements for an application, which in turn dictates the amount of space that the robot must be able to access and manipulate. For example, some applications require the robot to be able to reach every point in a container or box, while others only require the robot to be able to reach one particular area of the workspace.

Our engineers are knowledgeable and experienced in the entire range of automation technologies, including SCARA robots. We’re unbiased when it comes to selecting the right solution, which means that we are free to recommend any robotics manufacturer whose products meet our customer’s needs.
SCARA robots are ideal for small assembly applications where tolerances are measured in microns and speed is critical. The fact that they can be programmed with a simple graphic interface is another benefit. This makes them especially popular in industries like electromobility, solar power and electronics, where parts are small, low-volume and high-speed.
Choosing the correct end-of-arm tool (EOAT) is crucial for any robot application. The EOAT is what attaches to the end of the robot’s arm, and it can be anything from a simple gripper to a multipurpose end-of-arm-tool with dispensers or screwdrivers. The weight and inertia of the EOAT and the part being handled will determine the maximum payload that can be supported by a given SCARA robot. The length of the two arm links, their rotational degrees of freedom and the positioning repeatability of the axes will also affect the work envelope. For example, a midsized SCARA robot that has a 550-millimeter reach can support up to 10 kilograms of payload with a basic cycle time of 0.35 seconds.
