A parallel robotic mechanism having a large working area.

SCARA; Selective Compliant Assembly Robot Arm (also known as Selective Compliant Articulated Robot Arm) is a multi-axis robotic arm that can be accessed in any X-Y-Z, or rather R-θ-Z coordinates within the workspace. 'X' and 'Y' motion is obtained with three parallel axis rotary joints. The vertical motion 'Z' is usually an independent linear axis at the wrist or base.

SCARA robots are used in assembly operations where the final movement to insert the part is a single vertical movement. Inserting components into a printed circuit board may be an example. This is often referred to as "vertical assembly". Substrate transfer between processing chambers during electronic device manufacturing may be another common use for SCARA robots.

A feature of SCARA is a jointed two link arm arrangement, which may be similar to a human arm, and therefore often uses the term articulated. This property can be withdrawn or "folded" out of this path after the arm extends into the defined area. This is useful for transferring substrates from one chamber to another or in enclosed loading / unloading process stations.
