scara robot are a very common type of industrial robot for applications that require high accuracy and precision. They have a unique arm configuration that allows them to be compliant in the horizontal direction and rigid in the vertical direction, which makes them suitable for assembly tasks with tight tolerances, such as inserting a shaft into a hole. They are also very strong and can withstand sudden stress or collisions.
As a result, they are often used for repetitive tasks that would be difficult or unsafe for human workers. Examples include assembly of electrical and electronic components, small precision machine parts, or the handling and transfer of large automotive components. They have a wide variety of end-effectors available, including vacuum grippers and specialty holders designed to hold different sized parts. Additionally, they can be fitted with a vision system to track the position of parts on a conveyor belt and prevent them from falling off the line.

When Does a SCARA Robot Make Sense?
There are a lot of factors that go into choosing the correct robot for your application, and it’s not always clear cut. We recommend that you get in touch with our network of independent advisors to understand the specific details of your project and how a scara robot might be the best fit.
Cost is often the major deciding factor when evaluating robot types. While the costs of SCARAs vary from manufacturer to manufacturer, they are generally less expensive than other robot types. They also typically come with fewer components which helps reduce their overall cost.
The other key consideration is the work envelope of a robot. A SCARA has a circular workspace, which may not be ideal for some applications. It also lacks the dexterity and flexibility of other robot types, such as six-axis robots.
A new kinematic design for the linear motion of SCARA robots has been developed that can improve performance in a variety of applications by providing a single value of the optimal kinematic performance index (OKPI). It is based on an image of the workspace in which the manipulator generates quasi-optimal trajectories for the given ratio of link lengths, and it identifies the points on the workpiece that will be reached most frequently by the desired trajectory. In this way, the workpiece positioning error is minimized and the robot reaches more pick-and-place locations. This approach enables the development of a new generation of SCARAs with superior performance. In addition to this, it can also be applied to optimize the design of existing robots.
