<P> The second attribute of the SCARA is the jointed two - link arm layout similar to our human arms, hence the often - used term, Articulated . This feature allows the arm to extend into confined areas and then retract or "fold up" out of the way . This is advantageous for transferring parts from one cell to another or for loading / unloading process stations that are enclosed . </P> <P> SCARAs are generally faster and cleaner than comparable Cartesian robot systems . Their single pedestal mount requires a small footprint and provides an easy, unhindered form of mounting . On the other hand, SCARAs can be more expensive than comparable Cartesian systems and the controlling software requires inverse kinematics for linear interpolated moves . This software typically comes with the SCARA though and is usually transparent to the end - user . </P> <P> Most SCARA robots are based on serial architectures, which means that the first motor should carry all other motors . There also exists a so - called double - arm SCARA robot architecture, in which two of the motors are fixed at the base . The first such robot was commercialized by Mitsubishi Electric . Another example of a dual - arm SCARA robot is Mecademic's DexTAR educational robot . </P> <Ul> <Li> </Li> <Li> </Li> <Li> </Li> <Li> </Li> </Ul>
