The selection of which type of robot to choose is not always clear-cut, but Cyan Tec Systems are in a totally unbiased position to recommend solutions for the particular automation requirement. This article considers the specific case of the SCARA robot and when it is most likely advantageous to use one. In some cases the selection of the most suitable robot is straightforward and in others, it is mainly down to a comparison on costs. SCARA robots normally have up to 4 axes (3 rotation and one Z linear).
The SCARA robot is most commonly used for pick-and-place or assembly operations where high speed and high accuracy is required. Generally, a SCARA robot can operate at higher speed with optional cleanroom specification. In terms of repeatability, currently available SCARA robots can achieve tolerances lower than 10 microns, compared to 20 microns for a six-axis robot. By design, the SCARA robot suits applications with a smaller field of operation and where floor space is limited, the compact layout also making them more easily re-allocated in temporary or remote applications.
